2002-2007 Chris Schoeneman. +Synergy is distributed under the following license. + + GNU GENERAL PUBLIC LICENSE + Version 2, June 1991 + + Copyright (C) 1989, 1991 Free Software Foundation, Inc. + 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE +IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW.

That + enables a debug build of the installer. +- Fixes to compile under VS2005. + +I did not apply VS2005 project files, instead adding nmake files. nmake is +pretty weak but the makefiles can be modified without having visual studio. +Also modified the .rc files to not use winres.h. This plus nmake means +synergy can now be built using the freely downloadable Microsoft Windows +SDK for Vista, available from microsoft's web site. This change removes +all of the old VC++6 project files in favor of the nmake files.

There were two problems. +First the XkbLockGroup function was being called even for non-XKB +layouts. (And was being included in the compile even if the XKB +headers were not available!) Second, modifiers were assumed to +exist only the group in which a keysym was found and when looking +for modifiers for a key we only check modifiers in the same group. +So keys that needed Mode_switch (in group 1) would check to see if +Mode_switch was explictly mapped in group 1. It never is so that +would never work. Now we handle implicitly mapped modifiers. I +hadn't noticed this problem because my system (like most others) +uses XKB and when I forced non-XKB, the keys I tested worked anyway +through Multi_key. + +---------- +2006/04/01 22:25:33 crs +lib/platform/CXWindowsKeyState.cpp +lib/platform/CXWindowsKeyState.h +lib/platform/CXWindowsScreen.cpp + +Fixed autorepeat on X11.

Previously the server would send +ctrl and alt up events when sending a key that used AltGr then send +matching down events. Now we just clear the ctrl and alt bits in +the mask sent with the key; clients will temporarily release the +ctrl and alt modifiers as necessary to yield the key. If the key +doesn't need AltGr then the ctrl and alt bits are kept. We also +used to reserve the right alt key for AltGr even if the keyboard +layout didn't use it that way. This has been removed. The keyboard +mapping now presses the ctrl and alt keys for AltGr rather than use +the right alt. + +Also made getKeyID() a public method. + +---------- +2006/03/21 21:37:57 crs +lib/platform/CMSWindowsScreen.cpp +lib/platform/COSXScreen.cpp +lib/platform/CXWindowsScreen.cpp + +Improved log output when registering hot keys. + +---------- +2006/03/21 21:37:53 crs +cmd/synergyc/synergyc.cpp +cmd/synergys/synergys.cpp + +Added "server" and "client" to synergy log windows. + +---------- +2006/03/21 21:37:52 crs +lib/synergy/CKeyMap.cpp + +Fixed bug in keyboard mapping when releasing modifiers.

The PPC build +uses the 10.2.8 SDK while the i386 build uses the 10.4u SDK. Also +removed the "Default" configuration; "Development" is now the +default. + +---------- +2006/03/18 16:39:43 crs +lib/platform/COSXKeyState.cpp +lib/platform/COSXKeyState.h +lib/platform/COSXScreen.cpp + +Improved handling of option key on OS X servers. Previously it +was always treated as the super modifier. Now it's treated as +AltGr if it generates a glyph, though AltGr is not sent to the +clients. So if option+key produces a glyph then key is sent +without the option or AltGr modifiers. If option+key does not +produce a glpyh then option is sent as the super modifier. +Note that combining an option+key combination that would produce +a glyph with the command or control modifiers will cause it to +not produce a glyph. In that case we send option as the super +modifier and we send the glyph that would've been produced on +the server had the option key not been pressed. So option+s +sends the beta key id with no modifiers but command+option+s +sends the "s" key id with the alt and super modifiers. + +This seems to handle the user expectations. However some users +may expect option+L to produce win+L on win32 clients. These +same users probably expect option+? to produce an upside down +question mark. But these two expectations are fundamentally at +odds. We cannot satisfy everyone because OS X doesn't have +enough modifier keys. + +---------- +2006/03/18 13:20:18 crs +lib/server/CInputFilter.cpp + +Fixed mousebutton condition.

The assertion is blown because B owns the clipboard +but A sends a clipboard with a valid sequence number. The fix +is simply that clients must reset their internal clipboard +ownership flag when told to set the clipboard by the server. + +Second, synergy clients would fail to send the clipboard to the +server given the following sequence of events: + enter client A + A takes the clipboard + enter screen B + B takes the clipboard + enter A + A takes the clipboard with the same contents as before +In an effort to reduce bandwidth, clients don't send unchanged +clipboard contents.

This is a major change +to the client side handling of key events. This change converts the +X11 and win32 handling but not the OS X handling. + +The new class CKeyMap contains the information necessary to convert +a synergy key event to the platform events necessary to synthesize +the key. Platforms fill in a CKeyMap whenever their keyboard layouts +change using the addKeyEntry(), calling it once for each unique way +to synthesize a particular KeyID on the keyboard. The CKeyMap takes +it from there, first adding dead-key combinations and some other keys, +then doing the translation from KeyID to platform keystroke sequences. +Platforms no longer need to implement the KeyID to keystroke sequence +conversion, simplifying the platform implementations. + +This change also supports multiple keyboard layouts, typically used +to support various languages. If a key is not available on the active +layout but is on a different installed layout then synergy will switch +layouts automatically. + +The X11 version now fully supports the XKB extension.

It's reporting that a +non-blocking connect is available for writing (i.e. the connection +was successful) when the connection has actually failed. This +caused synergy to rapidly retry connecting. This change makes +synergy check for a connection error whether one was reported or +not. Thankfully, OS X does correctly set the socket error state +when it bogusly reports a successful connection so we can tell the +connection failed. + +---------- +2004/07/28 21:54:39 crs +lib/net/CTCPSocket.cpp + +Added workaround for apparent bug in OS X 10.3.4. If you started +a synergy client on that OS and pointed it at a system that wasn't +listening for connections then instead of the connection attempt +failing with 'connection refused' the system would claim the +connection succeeded. A subsequent read would reveal the problem +and synergy would "disconnect" and retry, causing the CPU to spin. +The system does correctly set the socket error state so this +workaround checks for socket errors when connecting whether or not +select reports an error state. + +Also, sometimes the system doesn't claim success but doesn't report +an error. Synergy eventually times out these attempts. + +---------- +2004/07/25 14:18:50 crs +configure.in +lib/common/Version.h + +Changed version to 1.1.8. + +---------- +2004/06/22 21:11:14 crs +lib/platform/CXWindowsScreen.cpp + +Disable key event capture on X11.

First, the mouse hook +now captures non-client area mouse messages. Previously, these +were ignored (because i forgot about them) and they caused all +kinds of problems because they weren't forwarded. For example, +clicking on a window border would cause the window to start +resizing when the mouse came back to the server screen.

(The window is still necessary +for clipboard ownership so it's still created.) No transparent +window means no screen flashing. It also means we don't have to +become the foreground and active window. This plays better with +apps that minimize or restore when they're no longer the +foreground application/active window. + +Third, fixed the low level keyboard hook to forward toggle key +updates, which it was neglecting to do. + +Finally, keyboard and mouse input is always forwarded from the hook +to the primary screen handler which then shadows the current key +and mouse button state. If we're using low level hooks then this +isn't really necessary and GetKeyState() always returns the right +info but without low level hooks it means we can just use the +shadow state. It also means we don't have to show our window in +order to get the system's key state table up to date, fixing the +screen flash when checking for the scroll lock state. + +---------- +2003/05/03 12:37:03 crs +lib/arch/CArchMultithreadWindows.cpp +lib/synergy/CPrimaryScreen.cpp +lib/synergy/CSecondaryScreen.cpp + +Boosted priority of main synergy threads to be very high (highest +realtime priority).

Fourth, scroll lock only locking to the client (which +only happened when using a synergy server on windows) has been fixed; +unfortunately the solution causes a lot of screen redraws for some +reason.

Contributed code should +following these guidelines. + +- Symbol Naming + Names always begin with a letter (never an underscore). The first + letter of interior names are always capitalized. Acronyms should + be all uppercase. For example: myTextAsASCII. + + Names come it two flavors: leading capital and leading lowercase. + The former have the first character capitalized and the latter + don't. In the following table, leading capital names are indicated + by `Name' and leading lowercase names by `name'. + + The naming convention for various things are: + + * Exceptions -- X + Name XMyException + * Interfaces -- I + Name IMyInterface + * Template Classes -- T + Name TMyTemplate<> + * Other Classes -- C + Name CMyClass + * Enumerations -- E + Name EMyEnumeration + * Constants -- k + Name kMyConstant + * Data Members -- m_ + name m_myDataMember + * Methods -- name myMethod + * Functions -- name myFunction + * Variables -- name myVariable + + Exceptions are types that get thrown and are generally derived + (possibly indirectly) from XBase. Interfaces are derived (possibly + indirectly) from IInterface and have only pure virtual functions. + Other classes are classes that aren't exceptions or interfaces. + Constants include global constants and enumerants. + + Method names should usually have the form `verbObject'. For example: + * isGameOn() + * getBeer() + * pressPowerButton() + * setChannel() + In general, use `get' and `set' to read and write state but use `is' + to read boolean state. Note that classes that contain only `is', + `get', and `set' are probably plain old data; you might want to + consider using public data members only or, better, refactor your + design to have classes that actually do something more than just + hold data. + +- File Naming + Each class should have one source and one header file. If the + class is named `CMyClass' then the source file should be named + `CMyClass.cpp' and the header file `CMyClass.h'. + + Headers files not containing a class should have some meaningful + name with a leading capital (e.g. `Version.h'). + + Source files without a header file have a leading lowercase name. + Only files containing the entry point for an application should + lack a header file. + +- Dependencies + * No circular library dependencies + Library dependencies form an acyclic graph. Conceptually + libraries can be arranged in layers where each library only + references libraries in layers below it, not in the same layer + or layers above it. The makefiles build the lowest layer + libraries first and work upwards. + + * Avoid circular uses-a relationships + When possible, design classes with one-way uses-a relationships + and avoid cycles. This makes it easier to understand the code. + However, sometimes it's not always practical so it is permitted. + + * Included files in headers + Headers should #include only the necessary headers. In + particular, if a class is referenced in a header file only as a + pointer or a reference then use `class COtherClass;' instead of + `#include "COtherClass.h".' + + * #include syntax + Non-synergy header files must be included using angle brackets + while synergy header files must be included using double quotes. + #include "CSynergyHeader.h" + #include + The file name in a #include must not be a relative path unless + it's a system header file and it's customary to use a relative + path, e.g. `#include '. Use compiler options to + add necessary directories to the include search path. + + * Included file ordering + Files should be included in the following order: + * Header for source file + The first include for CMyClass.cpp must be CMyClass.h. + * Other headers in directory, sorted alphabetically + * Headers for each library, sorted alphabetically per library + Include headers from the library closest in the dependency graph + first, then the next farthest, etc. Sort alphabetically within + each library. + * System headers + +- C++ + * C++ features + Synergy uses the following more recent C++ features: + * bool + * templates + * exceptions + * mutable + * new scoping rules + * the standard C++ library + + Do not use the following C++ features: + * dynamic_cast + * run time type information + * namespaces and using (use std:: where necessary) + + The new scoping rules say that the scope of a variable declared + in a for statement is limited to the for loop. For example: + + for (int i = 0; i < 10; ++i) { + // i is in scope here + } + // i is not in scope here + + for (int i = -10; i < 0; ++i) { + // an entirely new i is in scope here + } + // i is not in scope here + + This is used routinely in synergy, but only in for loops. There + is a macro for `for' in lib/base/common.h when building under + Microsoft Visual C++ that works around the fact that that compiler + doesn't follow the new scoping rules. Use the macro if your + compiler uses the old scoping rules. + + * Standard C++ library + The standard C++ library containers should always be used in favor + of custom containers wherever reasonable. std::string is used + throughout synergy but only as the CString typedef; always use + CString, never std::string except in the arch library. Synergy + avoids using auto_ptr due to some portability problems. Synergy + makes limited use of standard algorithms and streams but they can + be freely used in new code. + + * Limited multiple inheritance + Classes should inherit implementation from at most one superclass. + Inheriting implementation from multiple classes can have unpleasant + consequences in C++ due to it's limited capabilities. Classes can + inherit from any number of interface classes. An interface class + provides only pure virtual methods. Synergy breaks this rule in + IInterface which implements the virtual destructor for convenience. + + * No globals + Avoid global variables. All global variables must be static, making + it visible only with its source file. Most uses of global variables + are better served by static data members of a class. Global + constants are permitted in some circumstances. + + Also avoid global functions. Use public static member functions in + a class instead. + + These rules are violated by the main source file for each program + (except that the globals are still static). They could easily be + rewritten to put all the variables and functions into a class but + there's little to be gained by that. + + * Private data only + If a class is plain-old-data (i.e. it has no methods) all of its + data members should be public. Otherwise all of its data members + should be private, not public or protected. This makes it much + easier to track the use of a member when reading code. Protected + data is not allowed because `protected' is a synonym for `public + to my subclasses' and public data is a Bad Thing. While it might + seem okay in this limited situation, the situation is not at all + limited since an arbitrary number of classes can be derived, + directly or indirectly, from the class and any of those classes + have full access to the protected data. + + * Plain old data + A class that merely contains data and doesn't perform operations + on that data (other than reads and writes) is plain old data (POD). + POD should have only public data members and non-copy constructors. + It must not have any methods other than constructors, not even a + destructor or assignment operators, nor protected or private data. + Note that this definition of POD is not the definition used in the + C++ standard, which limits the contained data types to types that + have no constructors, destructors, or methods. + + * Avoid using friend + Avoid declaring friend functions or classes. They're sometimes + necessary for operator overloading. If you find it necessary to + add friends to some class C, consider creating a utility class U. + A utility class is declared as the only friend of C and provides + only static methods. Each method forwards to a private method on + an object of C type (passed as a parameter to the U's method). + This makes maintenance easier since only U has friend access to C + and finding any call to U is trivial (they're prefixed by U::). + + * Don't test for NULL when using `delete' or `delete[]' + It's unnecessary since delete does it anyway. + +- Makefiles + Automake's makefiles (named Makefile.am) have a few requirements: + * Define the following macro at the top of the file: + NULL = + * Lists should have one item per line and end in $(NULL). For + example: + EXTRA_DIST = \ + kiwi.txt \ + mango.cpp \ + papaya.h \ + $(NULL) + Indentation must use tabs in a makefile. Line continuations + (backslashes) should be aligned using tabs. + * Lists of files should be sorted alphabetically in groups (e..g + source files, header files, then other files). Lists of + subdirectories must be in the desired build order. + +- Source Formatting + Every project has its own formatting style and no style satisfies + everyone.

The mundane platform dependent parts +come from the usual suspects: networking, multithreading, file +system, high resolution clocks, system logging, etc. Porting +these parts is relatively straightforward. + +Synergy also has more esoteric platform dependent code. The +functions for low-level event interception and insertion, +warping the cursor position, character to keyboard event +translation, clipboard manipulation, and screen saver control +are often obscure and poorly documented. Unfortunately, these +are exactly the functions synergy requires to do its magic. + +Porting synergy to a new platform requires the following steps: + +- Setting up the build +- Adjusting lib/common/common.h +- Implementing lib/arch +- Implementing lib/platform +- Tweaks + +Setting up the build: + +The first phase is simply to create the files necessary to build the +other files. On Unix, synergy uses autoconf/automake which produces +a `configure' script that generates makefiles. On Windows, synergy +uses Visual C++ workspace and project files. If you're porting to +another Unix variant, you may need to adjust `configure.in', +`acinclude.m4', and Unix flavor dependent code in lib/arch. Note +especially the SYSAPI_* and WINAPI_* macro definitions in +ARCH_CFLAGS. Exactly one of each must be defined. It should also +add AM_CONDITIONALs if a new SYSAPI_* or WINAPI_* was added. + +Adjusting lib/common/common.h: + +The lib/common/common.h header file is included directly or indirectly +by every other file. Its primary job is to include config.h, which +defines macros depending on what the 'configure' script discovered +about the system. If the platform does not use the 'configure' script +it must define the appropriate SYSAPI_* and WINAPI_* macro. It may +also do other platform specific setup. + +Adjusting lib/common/BasicTypes.h: + +No changes should be necessary in BasicTypes.h. However, if the +platform's system header files define SInt8, et al. you may need +to adjust the typedefs to match the system's definitions. + +Implementing lib/arch: + +Much platform dependent code lives in lib/arch. There are several +interface classes there and they must all be implemented for each +platform. See the interface header files for more information. + +Platforms requiring special functions should create a class named +CArchMiscXXX where XXX is the platform name. The class should have +only static methods. Clients can include the appropriate header +file and make calls directly, surrounded by a suitable #ifdef/#endif. + +If using automake, the Makefile.am should list the system specific +files in a XXX_SOURCE_FILES macro where XXX matches the appropriate +AM_CONDITIONAL symbol. XXX_SOURCE_FILES must be added to EXTRA_DIST +and the following added above the INCLUDES macro: + + if XXX + libarch_a_SOURCES = \ + $(COMMON_SOURCE_FILES) \ + $(XXX_SOURCE_FILES) \ + $(NULL) + endif + +Implementing lib/platform: + +Most of the remaining platform dependent code lives in lib/platform. +The code there implements platform dependent window, clipboard, keyboard +and screen saver handling. If a platform is named XXX then the following +classes should be derived and implemented: + + * CXXXClipboard : IClipboard + Provides clipboard operations. Typically, this class will + have helper classes for converting between various clipboard + data formats. + + * CXXXEventQueueBuffer : IEventQueueBuffer + Provides operations for waiting for, posting and retrieving events. + Also provides operations for creating and deleting timers. + + * CXXXKeyState : CKeyState + Provides operations for synthesizing key events and for mapping a + key ID to a sequence of events to generate that key. + + * CXXXScreen : IScreen, IPrimaryScreen, ISecondaryScreen, IPlatformScreen + Provides screen operations. + + * CXXXScreenSaver : IScreenSaver + Provides screen saver operations. + +If using automake, the Makefile.am should list the window system +specific files in a XXX_SOURCE_FILES macro where XXX matches the +appropriate AM_CONDITIONAL symbol. XXX_SOURCE_FILES must be added +to EXTRA_DIST and the following added above the INCLUDES macro: + + if XXX + libplatform_a_SOURCES = $(XXX_SOURCE_FILES) + endif + +Tweaks: + +Finally, each platform typically requires various adjustments here +and there. In particular, synergyc.cpp and synergys.cpp usually +require platform dependent code for the main entry point, parsing +arguments, and reporting errors. Also, some platforms may benefit +from a graphical user interface front end. These are generally +not portable and synergy doesn't provide any infrastructure for +the code common to any platform, though it may do so someday. +There is, however, an implementation of a GUI front end for Windows +that serves as an example. diff --git a/doc/about.html b/doc/about.html new file mode 100644 index 00000000..aadd5764 --- /dev/null +++ b/doc/about.html @@ -0,0 +1,55 @@ + + + + + + + + About Synergy + + +

+With synergy, all the computers on your desktop form a single virtual +screen. You use the mouse and keyboard of only one of the computers +while you use all of the monitors on all of the computers. +You tell synergy how many screens you have and their positions relative +to one another. Synergy then detects when the mouse moves off +the edge of a screen and jumps it instantly to the neighboring screen. +The keyboard works normally on each screen; input goes to whichever +screen has the cursor. +

+In this example, the user is moving the mouse from left to right. +When the cursor reaches the right edge of the left screen it jumps +instantly to the left edge of the right screen. +

+

+

+You can arrange screens side-by-side, above and below one another, +or any combination. You can even have a screen jump to the opposite +edge of itself. Synergy also understands multiple screens attached +to the same computer. +

+Running a game and don't want synergy to jump screens? No problem. +Just toggle Scroll Lock. Synergy keeps the cursor on the same screen +when Scroll Lock is on. (This can be configured to another hot key.) +

+Do you wish you could cut and paste between computers? Now you can! +Just copy text, HTML, or an image as you normally would on one screen +then switch to another screen and paste it. It's as if all your +computers shared a single clipboard (and separate primary selection for +you X11 users). It even converts newlines to each computer's native +form so cut and paste between different operating systems works +seamlessly. And it does it all in Unicode so any text can be copied. +

+

+Do you use a screen saver? With synergy all your screen savers act in +concert. When one starts they all start. When one stops they all +stop. And, if you require a password to unlock the screen, you'll +only have to enter a password on one screen. +

+If you regularly use multiple computers on one desk, give synergy a +try. You'll wonder how you ever lived without it. +

Starting synergy automatically

+

+You can configure synergy to start automatically when the computer +starts or when you log in. The steps to do that are different on +each platform. Note that changing these configurations doesn't +actually start or stop synergy. The changes take effect the next +time you start your computer or log in. +

+

Windows

+

+Start synergy and click the Configure... button +by the text Automatic Startup. The +Auto Start dialog will pop up. +If an error occurs then correct the problem and click +Configure again. +

+On the Auto Start dialog you'll configure +synergy to start or not start automatically when the computer starts +or when you log in. You need Administrator access rights to start +synergy automatically when the computer starts. The dialog will let +you know if you have sufficient permission. +

+If synergy is already configured to automatically start then there +will be two Uninstall buttons, at most one +of which is enabled. Click the enabled button, if any, to tell +synergy to not start automatically. +

+If synergy is not configured to start automatically then there will +be two Install buttons. If you have +sufficient permission to have synergy start automatically when the +computer does then the Install button in the +When Computer Starts box will be enabled. +Click it to have synergy start for all users when the computer starts. +In this case, synergy will be available during the login screen. +Otherwise, click the Install button in the +When You Log In box to have synergy +automatically start when you log in. +

+

Unix

+

+Synergy requires an X server. That means a server must be +running and synergy must be authorized to connect to that server. +It's best to have the display manager start synergy. You'll need +the necessary (probably root) permission to modify the display +manager configuration files. If you don't have that permission +you can start synergy after logging in via the +.xsession file. +

+Typically, you need to edit three script files. The first file +will start synergy before a user logs in, the second will kill +that copy of synergy, and the third will start it again after +the user logs in. +

+The contents of the scripts varies greatly between systems so +there's no one definite place where you should insert your edits. +However, these scripts often exit before reaching the bottom so +put the edits near the top of the script. +

+The location and names of these files depend on the operating +system and display manager you're using. A good guess for the +location is /etc/X11. If you use kdm +then try looking in /etc/kde3 or +/usr/kde/version/share/config. +Typical file names are: +

+ + + + + + +
      xdm    kdm    gdm
1 xdm/Xsetup kdm/Xsetup gdm/Init/Default (*)
2 xdm/Xstartup kdm/Xstartup gdm/PostLogin/Default (*)
3 xdm/Xsession kdm/Xsession gdm/Sessions/Default (*, **)
+ +

+*) The Default file is used if no other +suitable file is found. gdm will try +displayname (e.g. :0) +and hostname (e.g. somehost), +in that order, before and instead of Default. +
+**) gdm may use gdm/Xsession, +xdm/Xsession or +dm/Xsession if +gdm/Sessions/Default doesn't exist. +

+For a synergy client, add the following to the first file: + + /usr/bin/killall synergyc + sleep 1 + /usr/bin/synergyc [<options>] synergy-server-hostname + +Of course, the path to synergyc depends on where you installed it +so adjust as necessary. +

+Add to the second file: + + /usr/bin/killall synergyc + sleep 1 + +

+And to the third file: + + /usr/bin/killall synergyc + sleep 1 + /usr/bin/synergyc [<options>] synergy-server-hostname + +Note that <options> +must not include +-f or --no-daemon or +the script will never exit and you won't be able to log in. +

+The changes are the same for the synergy server except replace +synergyc with synergys +and use the appropriate synergys command +line options. Note that the +first script is run as root so synergys will look for the configuration +file in root's home directory then in /etc. +Make sure it exists in one of those places or use the +--config config-pathname +option to specify its location. +

+Note that some display managers (xdm and kdm, but not gdm) grab +the keyboard and do not release it until the user logs in for +security reasons. This prevents a synergy server from sharing +the mouse and keyboard until the user logs in. It doesn't +prevent a synergy client from synthesizing mouse and keyboard +input, though. +

+If you're configuring synergy to start only after you log in then edit +your .xsession file. Add just what you +would add to the third file above. +

+

Mac OS X

+

+[By Tor Slettnes] +

+There are three different ways to automatically start Synergy +(client or server) on Mac OS X: +

+

    +
  1. + The first method involves creating a StartupItem + at the system level, which is executed when the machine starts up + or shuts down. This script will run in the background, and + relaunch synergy as needed. +

    +

    +
    Pros:
    +
    + Synergy is persistent, so this allows for a multi-user + setup and interactive logins. +
    +
    Cons:
    +
    + The synergy process does not have access to the clipboard + of the logged-in user. +
    +
    +
    2. +

    +

  2. + The second method will launch Synergy from the + LoginWindow application, once a particular + user has logged in. +

    +

    +
    Pros:
    +
    + The synergy process inherits the + $SECURITYSESSIONID environment variable, + and therefore copy/paste works. +
    +
    Cons:
    +
    + Once the user logs out, synergy dies, and no remote + control is possible. +
    +
    +
    3. +

    +

  3. + The third method is to launch a startup script from the + "Startup Items" tab under System Preferences -> Accounts. +

    +

    +
    Pros:
    +
    + Does not require root (Administrator) access +
    +
    Cons:
    +
    + Once the user logs out, synergy dies, and no remote + control is possible. +
    +
    +
    4. +
+

+The text below describes how to implement a Synergy client using +the first two methods simultaneously. This way, Synergy is +always running, and the clipboard is available when someone is +logged in. A Mac OS X Synergy server setup will be quite similar. +

+1. Create a System Level Startup Item +

+

    +
  • + Open a Terminal window, and become root: + + $ sudo su - + +
    • +
  • + Create a folder for this item: + + # mkdir -p /Library/StartupItems/Synergy + +
    • +
  • + In this folder, create a new script file by the same name as + the directory itself, Synergy. This script + should contain the following text: +

    + +#!/bin/sh +. /etc/rc.common +  +run=(/usr/local/bin/synergyc -n $(hostname -s) -1 -f synergy-server) +  +KeepAlive () +{ + proc=${1##*/} +  + while [ -x "$1" ] + do + if ! ps axco command | grep -q "^${proc}\$" + then + "$@" + fi +  + sleep 3 + done +} +  +StartService () +{ + ConsoleMessage "Starting Synergy" + KeepAlive "${run[@]}" & +} +  +StopService () +{ + return 0 +} +  +RestartService () +{ + return 0 +} +  +RunService "$1" + +

    + However, replace synergy-server with the actual + name or IP address of your Synergy server. +

    + Note that this scripts takes care not to start + Synergy if another instance is currently running. This + allows it to run in the background even when synergy is also + started independently, e.g. from the LoginWindow + application as described below. +

    • +
  • + Make this script executable: + + # chmod 755 /Library/StartupItems/Synergy/Synergy + +
    • +
  • + In the same folder, create a file named + StartupParameters.plist containing: +

    + +{ + Description = "Synergy Client"; + Provides = ("Synergy"); + Requires = ("Network"); + OrderPreference = "None"; +} + +

    • +
+

+That's it! If you want to test this setup, you can run the +startup script as follows: +

+ + # /Library/StartupItems/Synergy/Synergy start + +

+Any errors, as well as output from Synergy, will be shown in +your terminal window. +

+Next time you reboot, Synergy should start automatically. +

+2. Run Synergy When a User Logs In +

+Each time a user successfully logs in via the console, the +LoginWindow application creates a unique session +cookie and stores it in the environment variable +$SECURITYSESSIONID. For copy and paste operations +to work, Synergy needs access to this environment variable. In +other words, Synergy needs to be launched (directly or +indirectly) via the LoginWindow application. +

+However, in order to kill any synergy processes started at the +system level (as described above), we need root access. Thus, +launching Synergy within the User's environment (e.g. via the +Startup Items tab in System Preferences -> Accounts) is not an +option that work in conjunction with the method above. +

+Fortunately, the LoginWindow application provides +a "hook" for running a custom program (as root, with the username provided as +the first and only argument) once a user has authenticated, but +before the user is logged in. +

+Unfortunately, only one such hook is available. If you have +already installed a Login Hook, you may need to add the text +from below to your existing script, rather than creating a new +one. +

+

    +
  • + Launch a Terminal window, and become root: + + $ sudo su - + +
    • +

    +

  • + Find out if a LoginHook already exists: + + # defaults read com.apple.loginwindow LoginHook + + This will either show the full path to a script or + executable file, or the text: + + The domain/default pair of (com.apple.loginwindow, LoginHook) does not exist + + In the former case, you need to modify your existing script, + and/or create a "superscript" which in turn calls your + existing script plus the one we will create here. +

    + The rest of this text assumes that this item did not already + exist, and that we will create a new script. +

    • +
  • + Create a folder in which we will store our custom startup + script: + + # mkdir -p /Library/LoginWindow + +
    • +
  • + In this folder, create a new script file (let's name it + LoginHook.sh), containing the following text: +

    + +#!/bin/sh +prog=(/usr/local/bin/synergyc -n $(hostname -s) ip-address-of-server) +  +### Stop any currently running Synergy client +killall ${prog[0]##*/} +  +### Start the new client +exec "${prog[@]}" + +

    • +
  • + Make this script executable: + + # chmod 755 /Library/LoginWindow/LoginHook.sh + +
    • +
  • + Create a login hook to call the script you just created: + + # defaults write com.apple.loginwindow LoginHook /Library/LoginWindow/LoginHook.sh + +
    • +
+

+More information on setting up login hooks can be found at +Apple. +

+When running the Synergy client, you may need to use the IP +address of the Synergy server rather than its host name. +Specifically, unless you have listed the server in your +local /etc/hosts file or in your local NetInfo +database, name services (i.e. DNS) may not yet be available by the +time you log in after power-up. synergyc will +quit if it cannot resolve the server name. +

+(This is not an issue with the previous method, because the +StartupParameters.plist file specifies that this +script should not be run until "network" is available). +

+3. Good Luck! +

+Remember to look in your system log on both your server and your +client(s) for clues to any problems you may have +(/var/log/system.log on your OS X box, typically +/var/log/syslog on Linux boxes). +

Prerequisites for building

+

+To build synergy from the sources you'll need the following: +

    +
  • Windows +
      +
    • Microsoft Windows SDK for Vista; or +
    • VC++ 6.0 or up should work +
    +

    +

  • Unix +
      +
    • gcc 2.95 or up +
    • X11R4 or up headers and libraries +
    +

    +

  • Mac OS X +
      +
    • gcc 2.95 or up +
    • Carbon development headers and libraries +
    +
+

+

Configuring the build

+

+This step is not necessary on Windows. +

+To configure the build for your platform use the configure script: +

+  ./configure
+
+For a list of options to configure use: +
+  ./configure --help
+
+On Solaris you may need to use: +
+  ./configure --x-includes=/usr/openwin/include --x-libraries=/usr/openwin/lib
+
+so synergy can find the X11 includes and libraries. +

+

Building

+

    +
  • Windows +

    + Open a command prompt window (cmd.exe or command.exe). If necessary + run vcvars.bat, created when VC++ or Visual Studio was installed. (Use + search to find it.) It's necessary to run the file if you didn't have + the installer set up environment variables for you. Then enter: + 

    +  nmake /nologo /f Makefile.win
+
    + This will build the programs into build\Release. +

    +
  • Unix or Mac OS X +

    + Simply enter: + 

    +  make
+
    + This will build the client and server and leave them in their + respective source directories. +

    +
+

+

Installing

+

    +
  • Windows +

    + You'll need NSIS, + the Nullsoft Scriptable Install System. As in the building on Windows + description above, enter: + 

    +  nmake /nologo /f Makefile.win installer
+
    + to build build\Release\SynergyInstaller.exe. Run + this to install synergy. +

    + Alternatively, you can simply copy the following files from the + build\Release + directory to a directory you choose (perhaps under the + Program Files directory): +

      +
    • synergy.exe +
    • synergyc.exe +
    • synergys.exe +
    • synrgyhk.dll +
    +

    +
  • Unix or Mac OS X +

    + 

    +  make install
+
    + will install the client and server into + /usr/local/bin unless you + specified a different directory when you ran configure. +

    Synergy Configuration File Format

    +

    +The synergy server requires configuration. It will try certain +pathnames to load the configuration file if you don't specify a +path using the --config command line +option. synergys --help reports those +pathnames. +

    +The configuration file is a plain text file. Use any text editor +to create the configuration file. The file is broken into sections +and each section has the form: + + section: name + args + end + +Comments are introduced by # and continue to +the end of the line. name must be one of the +following: +

      +
    • screens +
    • aliases +
    • links +
    • options +
    +See below for further explanation of each section type. The +configuration file is case-sensitive so Section, +SECTION, and section +are all different and only the last is valid. Screen names are the +exception; screen names are case-insensitive. +

    +The file is parsed top to bottom and names cannot be used before +they've been defined in the screens or +aliases sections. So the +links and aliases +must appear after the screens and links +cannot refer to aliases unless the aliases +appear before the links. +

    +

    screens

    +

    +args is a list of screen names, one name per +line, each followed by a colon. Names are arbitrary strings but they +must be unique. The hostname of each computer is recommended. (This +is the computer's network name on win32 and the name reported by the +program hostname on Unix and OS X. Note +that OS X may append .local to the name you +gave your computer; e.g. somehost.local.) +There must be a screen name for the server and each client. Each +screen can specify a number of options. Options have the form +name = +value and are listed one per line +after the screen name. +

    +Example: + + section: screens + moe: + larry: + halfDuplexCapsLock = true + halfDuplexNumLock = true + curly: + meta = alt + end + +This declares three screens named moe, +larry, and curly. +Screen larry has half-duplex Caps Lock and +Num Lock keys (see below) and screen curly +converts the meta modifier key to the alt modifier key. +

    +A screen can have the following options: +

      +
    • halfDuplexCapsLock = {true|false} +

      + This computer has a Caps Lock key that doesn't report a + press and a release event when the user presses it but + instead reports a press event when it's turned on and a + release event when it's turned off. If Caps Lock acts + strangely on all screens then you may need to set this + option to true + on the server screen. If it acts strangely on one + screen then that screen may need the option set to + true. +

      +

    • halfDuplexNumLock = {true|false} +

      + This is identical to halfDuplexCapsLock + except it applies to the Num Lock key. +

      +

    • halfDuplexScrollLock = {true|false} +

      + This is identical to halfDuplexCapsLock + except it applies to the Scroll Lock key. Note that, by default, + synergy uses Scroll Lock to keep the cursor on the current screen. That + is, when Scroll Lock is toggled on, the cursor is locked to the screen + that it's currently on. You can use that to prevent accidental switching. + You can also configure other hot keys to do that; see + lockCursorToScreen. +

      +

    • switchCorners = <corners> +

      + See switchCorners below. +

      +

    • switchCornerSize = N +

      + See switchCornerSize below. +

      +

    • xtestIsXineramaUnaware = {true|false} +

      + This option works around a bug in the XTest extension + when used in combination with Xinerama. It affects + X11 clients only. Not all versions of the XTest + extension are aware of the Xinerama extension. As a + result, they do not move the mouse correctly when + using multiple Xinerama screens. This option is + currently true by default. If + you know your XTest extension is Xinerama aware then set + this option to false. +

      +

    • shift = {shift|ctrl|alt|meta|super|none}
      + ctrl = {shift|ctrl|alt|meta|super|none}
      + alt = {shift|ctrl|alt|meta|super|none}
      + meta = {shift|ctrl|alt|meta|super|none}
      + super = {shift|ctrl|alt|meta|super|none}       +

      + Map a modifier key pressed on the server's keyboard to + a different modifier on this client. This option only + has an effect on a client screen; it's accepted and + ignored on the server screen. +

      + You can map, say, the shift key to shift (the default), + ctrl, alt, meta, super or nothing. Normally, you + wouldn't remap shift or ctrl. You might, however, have + an X11 server with meta bound to the Alt keys. To use + this server effectively with a windows client, which + doesn't use meta but uses alt extensively, you'll want + the windows client to map meta to alt (using + meta = alt). +

      +

    +

    +

    aliases

    +

    + args is a list of screen names just like + in the screens section except each screen + is followed by a list of aliases, one per line, not followed + by a colon. An alias is a screen name and must be unique. During + screen name lookup each alias is equivalent to the screen name it + aliases. So a client can connect using its canonical screen name + or any of its aliases. +

    + Example: + + section: aliases + larry: + larry.stooges.com + curly: + shemp + end + + Screen larry is also known as + larry.stooges.com and can connect as + either name. Screen curly is also + known as shemp (hey, it's just an example). +

    +

    links

    +

    + args is a list of screen names just like + in the screens section except each screen + is followed by a list of links, one per line. Each link has the + form {left|right|up|down}[<range>] = + name[<range>]. A link indicates which + screen is adjacent in the given direction. +

    + Each side of a link can specify a range which defines a portion + of an edge. A range on the direction is the portion of edge you can + leave from while a range on the screen is the portion of edge you'll + enter into. Ranges are optional and default to the entire edge. All + ranges on a particular direction of a particular screen must not + overlap. +

    + A <range> is written as (<start>,<end>). + Both start and end + are percentages in the range 0 to 100, inclusive. The start must be + less than the end. 0 is the left or top of an edge and 100 is the + right or bottom. +

    + Example: + + section: links + moe: + right = larry + up(50,100) = curly(0,50) + larry: + left = moe + up(0,50) = curly(50,100) + curly: + down(0,50) = moe + down(50,100) = larry(0,50) + end + + This indicates that screen larry is to + the right of screen moe (so moving the + cursor off the right edge of moe would + make it appear at the left edge of larry), + the left half of + curly is above the right half of + moe, + moe is to the left of + larry (edges are not necessarily symmetric + so you have to provide both directions), the right half of + curly is above the left half of + larry, all of moe + is below the left half of curly, and the + left half of larry is below the right half of + curly. +

    + Note that links do not have to be + symmetrical; for instance, here the edge between + moe and curly + maps to different ranges depending on if you're going up or down. + In fact links don't have to be bidirectional. You can configure + the right of moe to go to + larry without a link from the left of + larry to moe. + It's possible to configure a screen with no outgoing links; the + cursor will get stuck on that screen unless you have a hot key + configured to switch off of that screen. +

    +

    options

    +

    + args is a list of lines of the form + name = value. These set the global + options. +

    + Example: + + section: options + heartbeat = 5000 + switchDelay = 500 + end + +

    + You can use the following options: +

      +
    • heartbeat = N +

      + The server will expect each client to send a message no + less than every N milliseconds. + If no message arrives from a client within + 3N seconds the server forces that + client to disconnect. +

      + If synergy fails to detect clients disconnecting while + the server is sleeping or vice versa, try using this + option. +

      +

    • switchCorners = <corners> +

      + Synergy won't switch screens when the mouse reaches the edge of + the screen if it's in a listed corner. The size of all corners + is given by the switchCornerSize + option. +

      + Corners are specified by a list using the following names: +

        +
      • none -- no corners +
      • top-left -- the top left corner +
      • top-right -- the top right corner +
      • bottom-left -- the bottom left corner +
      • bottom-right -- the bottom right corner +
      • left -- top and bottom left corners +
      • right -- top and bottom right corners +
      • top -- left and right top corners +
      • bottom -- left and right bottom corners +
      • all -- all corners +
      +

      + The first name in the list is one of the above names and defines + the initial set of corners. Subsequent names are prefixed with + + or - to add the corner to or remove the corner from the set, + respectively. For example: +

      + + all -left +top-left + +

      + starts will all corners, removes the left corners (top and bottom) + then adds the top-left back in, resulting in the top-left, + bottom-left and bottom-right corners. +

      +

    • switchCornerSize = N +

      + Sets the size of all corners in pixels. The cursor must be within + N pixels of the corner to be considered + to be in the corner. +

      +

    • switchDelay = N +

      + Synergy won't switch screens when the mouse reaches the + edge of a screen unless it stays on the edge for + N + milliseconds. This helps prevent unintentional + switching when working near the edge of a screen. +

      +

    • switchDoubleTap = N +

      + Synergy won't switch screens when the mouse reaches the + edge of a screen unless it's moved away from the edge + and then back to the edge within N + milliseconds. With + the option you have to quickly tap the edge twice to + switch. This helps prevent unintentional switching + when working near the edge of a screen. +

      +

    • screenSaverSync = {true|false} +

      + If set to false then synergy + won't synchronize screen savers. Client screen savers + will start according to their individual configurations. + The server screen saver won't start if there is input, + even if that input is directed toward a client screen. +

      +

    • relativeMouseMoves = {true|false} +

      + If set to true then secondary + screens move the mouse using relative rather than absolute + mouse moves when and only when the cursor is locked to the + screen (by Scroll Lock or a configured + hot key). + This is intended to make synergy work better with certain + games. If set to false or not + set then all mouse moves are absolute. +

      +

    • keystroke(key) = actions +

      + Binds the key combination key to the + given actions. key + is an optional list of modifiers (shift, + control, alt, + meta or super) + optionally followed by a character or a key name, all separated by + + (plus signs). You must have either + modifiers or a character/key name or both. See below for + valid key names. +

      + Actions are described below. +

      + Keyboard hot keys are handled while the cursor is on the primary + screen and secondary screens. Separate actions can be assigned + to press and release. +

      +

    • mousebutton(button) = actions +

      + Binds the modifier and mouse button combination + button to the given + actions. button + is an optional list of modifiers (shift, + control, alt, + meta or super) + followed by a button number. The primary button (the + left button for right handed users) is button 1, the middle button + is 2, etc. +

      + Actions are described below. +

      + Mouse button actions are not handled while the cursor is on the + primary screen. You cannot use these to perform an action while + on the primary screen. Separate actions can be assigned to press + and release. +

      +

    + You can use both the switchDelay and + switchDoubleTap options at the same + time. Synergy will switch when either requirement is satisfied. +

    +Actions are two lists of individual actions separated +by commas. The two lists are separated by a semicolon. Either list can be +empty and if the second list is empty then the semicolon is optional. The +first list lists actions to take when the condition becomes true (e.g. the +hot key or mouse button is pressed) and the second lists actions to take +when the condition becomes false (e.g. the hot key or button is released). +The condition becoming true is called activation and becoming false is +called deactivation. +Allowed individual actions are: +

      +
    • keystroke(key[,screens]) +
    • keyDown(key[,screens]) +
    • keyUp(key[,screens]) +

      + Synthesizes the modifiers and key given in key + which has the same form as described in the + keystroke option. If given, + screens lists the screen or screens to + direct the event to, regardless of the active screen. If not + given then the event is directed to the active screen only. + (Due to a bug, keys cannot be directed to the server while on a + client screen.) +

      + keyDown synthesizes a key press and + keyUp synthesizes a key release. + keystroke synthesizes a key press on + activation and a release on deactivation and is equivalent to + a keyDown on activation and + keyUp on deactivation. +

      + screens is either * + to indicate all screens or a colon (:) separated list of screen + names. (Note that the screen name must have already been encountered + in the configuration file so you'll probably want to put actions at + the bottom of the file.) +

      +

    • mousebutton(button) +
    • mouseDown(button) +
    • mouseUp(button) +

      + Synthesizes the modifiers and mouse button given in + button + which has the same form as described in the + mousebutton option. +

      + mouseDown synthesizes a mouse press and + mouseUp synthesizes a mouse release. + mousebutton synthesizes a mouse press on + activation and a release on deactivation and is equivalent to + a mouseDown on activation and + mouseUp on deactivation. +

      +

    • lockCursorToScreen(mode) +

      + Locks the cursor to or unlocks the cursor from the active screen. + mode can be off + to unlock the cursor, on to lock the + cursor, or toggle to toggle the current + state. The default is toggle. If the + configuration has no lockCursorToScreen + action and Scroll Lock is not used as a hot key then Scroll Lock + toggles cursor locking. +

      +

    • switchToScreen(screen) +

      + Jump to screen with name or alias screen. +

      +

    • switchInDirection(dir) +

      + Switch to the screen in the direction dir, + which may be one of left, + right, up or + down. +

      +

    • keyboardBroadcast(mode[,screens]) +

      + Turns broadcasting of keystrokes to multiple screens on and off. When + turned on all key presses and releases are sent to all of the screens + listed in screens. If not given, empty or + * then keystrokes are broadcast to all screens. + (However, due to a bug, keys cannot be sent to the server while on a + client screen.) +

      + mode can be off + to turn broadcasting off, on to turn it + on, or toggle to toggle the current + state. The default is toggle. +

      + screens is either * + to indicate all screens or a colon (:) separated list of screen + names. (Note that the screen name must have already been encountered + in the configuration file so you'll probably want to put actions at + the bottom of the file.) +

      + Multiple keyboardBroadcast actions may be + configured with different screens. The most + recently performed action defines the screens to broadcast to. +

      +

    +

    +Examples: +

      +
    • keystroke(alt+left) = switchInDirection(left) +

      + Switches to the screen to left when the left arrow key is pressed + in combination with the Alt key. +

      +

    • keystroke(shift+control+alt+super) = switchToScreen(moe) +

      + Switches to screen moe when all of the + Shift, Control, Alt, and Super modifier keys are pressed together. +

      +

    • keystroke(alt+f1) = ; lockCursorToScreen(toggle) +

      + Toggles locking the cursor to the screen when Alt+F1 is released. +

      +

    • mousebutton(2) = mouseDown(control+1) ; mouseUp(control+1) +

      + While on a secondary screen clicking the middle mouse button will + become a Control click of the primary button. +

      +

    • keystroke(super+f1) = keystroke(super+L,larry), keystroke(control+alt+delete,curly) +

      + Pressing Super+F1 (on any screen) will synthesize Super+L on screen + larry and Control+Alt+Delete on screen + curly. +

      +

    +Synergy is reasonably well commented so reading the source code +should be enough to understand particular pieces. See the +doc/PORTING +file in the synergy source code for more high-level information. +

    +

    How it works

    +

    +The theory behind synergy is simple: the server captures mouse, +keyboard, clipboard, and screen saver events and forwards them to +one or more clients. If input is directed to the server itself +then the input is delivered normally. In practice, however, many +complications arise. +

    +First, different keyboard mappings can produce different characters. +Synergy attempts to generate the same character on the client as +would've been generated on the server, including appropriate modifier +keys (like Control and Alt). Non-character keys like Shift are also +synthesized if possible. Sometimes the client simply cannot create +the character or doesn't have a corresponding non-character key and +synergy must discard the event. Note that synergy won't necessarily +synthesize an event for the corresponding key on the client's +keyboard. For example, if the client or server can't distinguish +between the left and right shift keys then synergy can't be certain +to synthesize the shift on the same side of the keyboard as the user +pressed. +

    +Second, different systems have different clipboards and clipboard +formats. The X window system has a system-wide selection and +clipboard (and yet other buffers) while Microsoft Windows has only +a system-wide clipboard. Synergy has to choose which of these +buffers correspond to one another. Furthermore, different systems +use different text encodings and line breaks. Synergy mediates and +converts between them. +

    +Finally, there are no standards across operating systems for some +operations that synergy requires. Among these are: intercepting +and synthesizing events; enabling, disabling, starting and stopping +the screen saver; detecting when the screen saver starts; reading +and writing the clipboard(s). +

    +All this means that synergy must be customized to each operating +system (or windowing system in the case of X windows). Synergy +breaks platform differences into two groups. The first includes +the mundane platform dependent things: file system stuff, +multithreading, network I/O, multi-byte and wide character +conversion, time and sleeping, message display and logging, and +running a process detached from a terminal. This code lives in +lib/arch. +

    +The second includes screen and window management handling, user +event handling, event synthesis, the clipboards, and the screen +saver. This code lives in lib/platform. +

    +For both groups, there are particular classes or interfaces that +must be inherited and implemented for each platform. See the +doc/PORTING file in the synergy source +code for more information. +

    +

    Auto-generated Documentation

    +

    +Synergy can automatically generate documentation from the comments +in the code using doxygen. +Use make doxygen to build it yourself +from the source code into the doc/doxygen/html +directory. +

    Answers

    +
      +
    1. Why doesn't ctrl+alt+del work on secondary screens? +

      + Synergy isn't able to capture ctrl+alt+del on PC compatible + primary screens because it's handled completely differently than + other keystrokes. However, when the mouse is on a client + screen, pressing ctrl+alt+pause will simulate ctrl+alt+del + on the client. (A client running on Windows NT, 2000, or XP + must be configured to autostart when the computer starts for + this to work.) +

      + On a primary screen running on an OS X system, you can use + ctrl+command+del. Using the pause key isn't necessary since OS X + doesn't treat ctrl+command+del differently. And using the pause + key isn't usually possible because there isn't one on most OS X + systems. Use command instead of option/alt because + the command key, not the option/alt key, maps to alt on windows. + The reason is because the command key is in the same physical + location and performs the same general function (menu shortcuts) + as alt on a windows system. This mapping can be modified in + the configuration. +

      + On mac laptops, the key labeled "delete" is actually backspace + and ctrl+command+delete won't work. However fn+delete really + is delete so fn+ctrl+command+delete will act as ctrl+alt+del + on a windows secondary screen. +

      +
    2. Can the server and client be using different operating systems? +

      + Yes. The synergy network protocol is platform neutral so + synergy doesn't care what operating systems are running on + the server and clients. +

      +
    3. What's the difference between synergy and +x2x, x2vnc, etc? +

      + Unlike x2x, synergy supports any number of computers and + it doesn't require X on Microsoft Windows platforms. It + also has more advanced clipboard support and synchronizes + screensavers. x2vnc is also limited to two computers, + requires the separate vnc package, and is really only + appropriate for using an X system to control a non-X system. + However, the right tool for the job is whatever tool works + best for you. +

      +
    4. What does "Cannot initialize hook library" mean? +

      + This error can occur on a synergy server running on a + Microsoft Windows operating system. It means that synergy + is already running or possibly was not shut down properly. + If it's running then first end the synergy task. If it's + not then try logging off and back on or rebooting then + starting synergy again. +

      +
    5. What security/encryption does synergy provide? +

      + Synergy provides no built-in encryption or authentication. + Given that, synergy should not be used on or over any untrusted + network, especially the Internet. It's generally fine for home + networks. Future versions may provide built-in encryption and + authentication. +

      + Strong encryption and authentication is available through SSH + (secure shell). Run the SSH daemon (i.e. server) on the same + computer that you run the synergy server. It requires no + special configuration to support synergy. On each synergy + client system, run SSH with port forwarding: +

      +

      +        ssh -f -N -L 24800:server-hostname:24800 server-hostname
+
      +

      + where server-hostname is the name of the + SSH/synergy server. + Once ssh authenticates itself, start the synergy client + normally except use localhost or + 127.0.0.1 as the server's + address. SSH will then encrypt all communication on behalf of + synergy. Authentication is handled by the SSH authentication. +

      + A free implementation of SSH for Linux and many Unix systems is + OpenSSH. For + Windows there's a port of OpenSSH using + Cygwin. +

      +
    6. What should I call my screens in the configuration? +

      + You can use any unique name in the configuration file for each + screen but it's easiest to use the hostname of the computer. + That's the computer name not including the domain. For example, + a computer with the fully qualified domain name xyz.foo.com has + the hostname xyz. There should also be an alias for xyz to + xyz.foo.com. If you don't use the computer's hostname, you + have to tell synergy the name of the screen using a command line + option, or the startup dialog on Windows. +

      + Some systems are configured to report the fully qualified domain + name as the hostname. For those systems it will be easier to use + the FQDN as the screen name. Also note that a Mac OS X system + named xyz may report its hostname as + xyz.local. If that's the case for you + then use xyz.local as the screen name. +

      +
    7. Why do my Caps-Lock, Num-Lock, Scroll-Lock keys act funny? +

      + Some systems treat the Caps-Lock, Num-Lock, and Scroll-Lock keys + differently than all the others. Whereas most keys report going down + when physically pressed and going up when physically released, on + these systems the Caps-Lock and Num-Lock keys report going down + when being activated and going up when being deactivated. That + is, when you press and release, say, Caps-Lock to activate it, it + only reports going down, and when you press and release to + deactivate it, it only reports going up. This confuses synergy. +

      + You can solve the problem by changing your configuration file. + In the screens section, following each screen that has the + problem, any or all of these lines as appropriate: +

      +

      +        halfDuplexCapsLock = true
+        halfDuplexNumLock = true
+        halfDuplexScrollLock = true
+
      +

      + Then restart synergy on the server or reload the configuration. +

      +
    8. Can synergy share the display in addition to the mouse and keyboard? +

      + No. Synergy is a KM solution not a KVM (keyboard, video, mouse) + solution. However, future versions will probably support KVM. + Hopefully, this will make synergy suitable for managing large + numbers of headless servers. +

      +
    9. Can synergy do drag and drop between computers? +

      + No. That's a very cool idea and it'll be explored. However, it's + also clearly difficult and may take a long time to implement. +

      +
    10. Does AltGr/Mode-Switch/ISO_Level3_Shift work? +

      + Yes, as of 1.0.12 synergy has full support for AltGr/Mode-switch. + That includes support for most (all?) European keyboard layouts. + All systems should be using the same keyboard layout, though, for + all characters to work. (Any character missing from a client's + layout cannot be generated by synergy.) There is experimental + support for ISO_Level3_Shift in 1.1.3. +

      +
    11. Why isn't synergy ported to platform XYZ? +

      + Probably because the developers don't have access to platform XYZ + and/or are unfamiliar with development on XYZ. Also, synergy has + inherently non-portable aspects so there's a not insignificant + effort involved in porting. +

      +
    12. My client can't connect. What's wrong? +

      + A common mistake when starting the client is to give the wrong + server host name. The last synergyc command line option (Unix) + or the "Server Host Name" edit field (Windows) should be the + host name (or IP address) of the server not the client's host + name. If you get the error connection failed: cannot connect + socket followed by the attempt to connect was forcefully + rejected or connection refused then the server isn't started, + can't bind the address, or the client is connecting to the wrong + host name/address or port. See the + troublshooting page for more help. +

      +
    13. Linking fails on Solaris. What's wrong? +

      + Did you add +

      +

      +        --x-includes=/usr/openwin/include --x-libraries=/usr/openwin/lib
+
      +

      + to the configure command line? Solaris puts + the X11 includes and libraries in an unusual place and the above lets + synergy find them. +

      +
    14. The screen saver never starts. Why not? +

      + If the synergy server is on X Windows then the screen saver will + not start while the mouse is on a client screen. This is a + consequence of how X Windows, synergy and xscreensaver work. +

      +
    15. I can't switch screens anymore for no apparent reason. Why? +

      + This should not happen with 1.1.3 and up. Earlier versions of + synergy would not allow switching screens when a key was down and + sometimes it would believe a key was down when it was not. +

      +
    16. I get the error 'Xlib: No protocol specified'. Why? +

      + You're running synergy without authorization to connect to the + X display. Typically the reason is running synergy as root when + logged in as non-root. Just run synergy as the same user that's + logged in. +

      +
    17. The cursor goes to secondary screen but won't come back. Why? +

      + Your configuration is incorrect. You must indicate the neighbors + of every screen. Just because you've configured 'Apple' to be to + the left of 'Orange' does not mean that 'Orange' is to the right + of 'Apple'. You must provide both in the configuration. +

      +
    18. The cursor wraps from one edge of the screen to the opposite. Why? +

      + Because you told it to. If you list 'Orange' to be to the left of + 'Orange' then moving the mouse off the left edge of 'Orange' will + make it jump to the right edge. Remove the offending line from the + configuration if you don't want that behavior. +

      +
    19. How do I stop my game from minimizing when I leave the screen? +

      + Many full screen applications, particularly games, automatically + minimize when they're no longer the active (foreground) application + on Microsoft Windows. The synergy server normally becomes the foreground + when you switch to another screen in order to more reliably capture all + user input causing those full screen applications to minimize. To + prevent synergy from stealing the foreground just click "Options..." + and check "Don't take foreground window on Windows servers." If you + turn this on then be aware that synergy may not function correctly when + certain programs, particularly the command prompt, are the foreground + when you switch to other screens. Simply make a different program the + foreground before switching to work around that. +

    Synergy History

    +

    +The first incarnation of synergy was CosmoSynergy, created by +Richard Lee and Adam Feder then at Cosmo Software, Inc., a +subsidiary of SGI (nee Silicon Graphics, Inc.), at the end of +1996. They wrote it, and Chris Schoeneman contributed, to +solve a problem: most of the engineers in Cosmo Software had +both an Irix and a Windows box on their desks and switchboxes +were expensive and annoying. CosmoSynergy was a great success +but Cosmo Software declined to productize it and the company +was later closed. +

    +Synergy is a from-scratch reimplementation of CosmoSynergy. +It provides most of the features of the original and adds a +few improvements. +

    Introduction

    +synergy: [noun] a mutually advantageous conjunction of distinct elements +

    +Synergy lets you easily share a single mouse and keyboard between +multiple computers with different operating systems, each with its +own display, without special hardware. It's intended for users +with multiple computers on their desk since each system uses its +own monitor(s). +

    +Redirecting the mouse and keyboard is as simple as moving the mouse +off the edge of your screen. Synergy also merges the clipboards of +all the systems into one, allowing cut-and-paste between systems. +Furthermore, it synchronizes screen savers so they all start and stop +together and, if screen locking is enabled, only one screen requires +a password to unlock them all. Learn more +about how it works. +

    +Synergy is open source and released under the +GNU Public License (GPL). +

    System Requirements

    +

    +

      +
    • Microsoft Windows 95, Windows 98, Windows Me (the Windows 95 family) +
    • Microsoft Windows NT, Windows 2000, Windows XP (the Windows NT family) +
    • Mac OS X 10.2 or higher +
    • Unix +
        +
      • X Windows version 11 revision 4 or up +
      • XTEST extension
        + (use "xdpyinfo | grep XTEST" to check for XTEST) +
      +
    +All systems must support TCP/IP networking. +

    +"Unix" includes Linux, Solaris, Irix and other variants. Synergy has +only been extensively tested on Linux and may not work completely or +at all on other versions of Unix. Patches are welcome (including +patches that package binaries) at the +patches page. +

    +The Mac OS X port is incomplete. It does not synchronize the screen saver, +only text clipboard data works (i.e. HTML and bitmap data do not work), +the cursor won't hide when not on the screen, and there may be problems +with mouse wheel acceleration. Other problems should be +filed as bugs. +

    +

    GNU GENERAL PUBLIC LICENSE

    +Version 2, June 1991 +

    +Copyright (C) 1989, 1991 Free Software Foundation, Inc.
    +59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
    +Everyone is permitted to copy and distribute verbatim copies +of this license document, but changing it is not allowed. +

    +

    Preamble

    +

    + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. +

    + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. +

    + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. +

    + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. +

    + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. +

    + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. +

    + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. +

    + The precise terms and conditions for copying, distribution and +modification follow. +

    +

    GNU GENERAL PUBLIC LICENSE
    +TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

    +

    + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". +

    +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. +

    + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. +

    +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. +

    + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: +

    + +
         +

    + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. +

    + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. +

    + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) +

    +

    +

    +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. +

    +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. +

    +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. +

    + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: +

    + +
         +

    + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, +

    + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, +

    + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) +

    +

    +

    +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. +

    +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. +

    + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. +

    + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. +

    + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. +

    + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. +

    +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. +

    +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. +

    +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. +

    + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. +

    + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. +

    +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. +

    + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. +

    +NO WARRANTY +

    + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE +IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE +COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM +"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR +IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES +OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE +ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. +

    + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED +TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY +WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED +ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, +SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF +THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT +LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR +LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE +PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH +HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. +

    • Fixed Scroll Lock not locking cursor to screen +
    • Fixed mapping of delete key on X11 +
    • Fixed loss of clipboard after a particular copy/paste sequence +
    • Fixed compatibility with windows 95/98/Me (ToUnicodeEx) +
    • Fixed bad argument to function on OS X +

    +

    +Hot keys support has one known major bug: key actions cannot be directed +to the server (primary) screen. The configuration file syntax has changed +from earlier versions; users will have to modify the configurations by +hand. +

    +Dec-18-2005 - Synergy 1.2.7 released +

    +Made following changes: +

      +
    • Added preliminary support for configurable hot keys (Lorenz Schori) +

    • Fixed control and alt keys getting stuck on on X11 +
    • Fixed desktop focus problems requiring extra clicks on win32 +
    • Fixed alt key event getting passed to server when on client on win32 +
    • Synergy would prevent alt+numpad character entry; this is fixed +

    Synergy Roadmap

    +

    +This page describes the planned development of Synergy. There are +no dates or deadlines. Instead, you'll find the features to come +and the rough order they'll arrive. +

    +

    Short term

    +

    +Synergy should work seamlessly. When it works correctly, it works +transparently so you don't even think about it. When it breaks, +you're forced out of the illusion of a unified desktop. The first +priority is fixing those bugs that break the illusion. +

    +Some of these bugs are pretty minor and some people would rather +have new features first. But I'd rather fix the current +foundation before building on it. That's not to say features +won't get added until after bug fixes; sometimes it's just too +tempting to code up a feature. +

    +The highest priority feature is currently splitting synergy into +front-ends and a back-end. The back-end does the real work. The +front-ends are console, GUI, or background applications that +communicate with the back-end, either controlling it or receiving +notifications from it. +

    +On win32, there'd be a front-end for the tray icon and a dialog to +start, stop, and control the back-end. OS X and X11 would have +similar front-ends. Splitting out the front-end has the added +benefit on X11 of keeping the back-end totally independent of +choice of GUI toolkit (KDE, Gnome, etc.) +

    +One can also imagine a front-end that does nothing but put monitors +into power-saving mode when the cursor is not on them. If you have +one monitor auto-senses two inputs, this would automatically switch +the display when you move the cursor to one screen or another. +

    +

    Medium term

    +

    +Some features fit well into Synergy's current design and may simply +enhance it's current capabilities. +

    +

      +
    • Configurable hot key to pop up a screen switch menu +
    • Configure screen saver synchronization on or off +
    • Graphical interface configuration and control on all platforms +
    • Graphical status feedback on all platforms +
    • More supported clipboard formats (particularly rich text) +
    +

    +A popup menu would be new for Synergy, which currently doesn't have +to do any drawing. That opens up many possibilities. Ideally, +front-ends request hot keys from the back-end and then tell the back +end what to do when they're invoked. This keeps the back-end +independent of the user interface. +

    +

    Long term

    +

    +Two features stand out as long term goals: +

    +

      +
    • Support N computers on +M monitors +
    • Drag and drop across computers +
    +

    +The first feature means sharing a monitor or monitors the way the +keyboard and mouse are shared. With this, Synergy would be a full +KVM solution. Not only would it support a few computers sharing +one screen (still using the mouse to roll from one screen to +another), but it should also support dozens of computers to provide +a solution for server farm administrators. In this capacity, it +may need to support text (as opposed to bitmap graphics) screens. +

    +The second feature would enhance the unified desktop illusion. It +would make it possible to drag a file and possibly other objects +to another screen. The object would be copied (or moved). I expect +this to be a very tricky feature. +

    +Synergy lets you use one keyboard and mouse across multiple computers. +To do so it requires that all the computers are connected to each other +via TCP/IP networking. Most systems come with this installed. +

    +

    Step 1 - Choose a server

    +

    +The first step is to pick which keyboard and mouse you want to share. +The computer with that keyboard and mouse is called the "primary +screen" and it runs the synergy server. All of the other computers +are "secondary screens" and run the synergy client. +

    +

    Step 2 - Install the software

    +

    +Second, you install the software. Choose the appropriate package +and install it. For example, on Windows you would run +SynergyInstaller. You must install the +software on all the computers that will share the mouse and keyboard +(clients and server). On OS X you'll just have a folder with some +documentation and two programs. You can put this folder anywhere. +

    +

    Step 3 - Configure and start the server

    +

    +Next you configure the server. You'll tell synergy the name of +the primary and secondary screens, which screens are next to which, +and choose desired options. On Windows there's a dialog box for +setting the configuration. On other systems you'll create a simple +text file. +

    + +Note that when you tell synergy that screen A +is to the left of screen B this does not +imply that B is to the right of +A. You must explicitly indicate both +relations. If you don't do both then when you're running synergy you'll +find you're unable to leave one of the screens. +

    +Windows
    +On Windows run synergy by double clicking on the +synergy file. This brings up a dialog. +Configure the server: +

      +
    • Click the Share this computer's keyboard and mouse (server) radio button +
    • Click the Screens & Links Configure... button +
    • Click the + button to add the server to the + Screens list +
        +
      • Enter the name of server (the computer's name is the recommended name) +
      • Optionally enter other names the server is known by +
      • Click OK +
      +
    • Use the + button to add your other computers +
        +
      • Using a computer's name as its screen name is recommended +
      • Choose desired screen options on the Add Screen dialog +
      +
    • Use the controls under Links to link screens together +
        +
      • Click (once) on the server's name in the Screens list +
      • Choose the screen to the left of the server; use --- + if there is no screen to the left of the server +
      • Choose the screens to the right, above and below the server +
      • Repeat the above steps for all the other screens +
      +
    • Click OK to close the Screens & Links dialog +
    • Use Options... to set desired options +
    • If the server's screen name is not the server's computer name: +
        +
      • Click Advanced... +
      • Enter the server's screen name next to + Screen Name +
      • Click OK +
      +
    +

    +Now click Test. The server will start and +you'll see a console window with log messages telling you about synergy's +progress. If an error occurs you'll get one or more dialog boxes telling +you what the errors are; read the errors to determine the problem then +correct them and try Test again. See Step 5 +for typical errors. +

    +Unix or Mac OS X
    +Create a text file named synergy.conf with the +following: +

    +    section: screens
+       screen1:
+       screen2:
+    end
+    section: links
+       screen1:
+           right = screen2
+       screen2:
+           left = screen1
+    end
+
    +Replace each occurrence of screen1 with the host name +of the primary screen computer (as reported by the +hostname program) and screen2 +with the host name of a secondary screen computer. In the above example, +screen2 is to the right of +screen1 and screen1 is to the +left of screen2. If necessary you should replace +right and left with +left, right, +up, or down. If you +have more than two computers you can add those too: add each computer's host +name in the screens section and add the +appropriate links. See the configuration +guide for more configuration possibilities. +

    +Now start the server. Normally synergy wants to run "in the background." +It detaches from the terminal and doesn't have a visible window, effectively +disappearing from view. Until you're sure your configuration works, you +should start synergy "in the foreground" using the -f +command line option. +

    +On unix type the command below in a shell. If synergys is not in your +PATH then use the full pathname. +

    +    synergys -f --config synergy.conf
+
    +On OS X open Terminal in the Utilities folder in the Applications folder. +Drag the synergys program from the synergy folder onto the Terminal window. +The path to the synergys program will appear. Add the following to the +same line, type a space at the end of the line but don't press enter: +
    +    -f --config 
+
    +Now drag the synergy.conf file onto the Terminal window and press enter. +Check the reported messages for errors. Use ctrl+c to stop synergy if +it didn't stop automatically, correct any problems, and start it again. +

    +

    Step 4 - Start the clients

    +

    +Next you start the client on each computer that will share the server's +keyboard and mouse. +

    +Windows
    +On Windows run synergy by double clicking on the +synergy file. This brings up a dialog. +Configure the client: +

      +
    • Click the Use another computer's shared keyboard and mouse (client) radio button +
    • Enter the server's computer name next to Other Computer's Host Name +
        +
      • This is not the server's screen name, unless you made that the + server's host name as recommended +
      +
    • If the client's screen name is not the client's computer name: +
        +
      • Click Advanced... +
      • Enter the client's screen name next to Screen Name +
      • Click OK +
      +
    +

    +Now click Test. +

    +Unix or Mac OS X
    +To start a client on unix, enter the following: +

    +    synergyc -f server-host-name
+
    +where server-host-name is replaced by the host +name of the computer running the synergy server. If synergyc is not in +your PATH then use the full pathname. +

    +On OS X open Terminal in the Utilities folder in the Applications folder. +Drag the synergyc program from the synergy folder onto the Terminal window. +The path to the synergys program will appear. Add the following to the +same line and press enter: +

    +    -f server-host-name
+
    +

    +When you added the client to the server's configuration you chose a +name for the client. If that name was not client's host name then +you must tell the client the name you used. Instead of the above +command use this instead: +

    +    synergyc -f --name name server-host-name
+
    +where name is the name for the client in +the server's configuration. (On OS X drag the synergyc program to the +Terminal window rather than typing synergyc.) +

    +

    Step 5 - Test

    +

    +Clients should immediately report a successful connection or one or +more error messages. Some typical problems and possible solutions are +below. See the troubleshooting and the +FAQ pages for more help. +

      +
    • failed to open screen (X11 only) +

      + Check permission to open the X display;
      + check that the DISPLAY environment variable is set
      + use the --display command line option. +

      +

    • address already in use +

      + Another program (maybe another copy of synergy) is using the synergy port; + stop the other program or choose a different port in the + Advanced... dialog. If you change the port + you must make the same change on all of the clients, too. +

      +

    • connection forcefully rejected +

      + The synergy client successfully contacted the server but synergy wasn't + running or it's running on a different port. You may also see this if + there's a firewall blocking the host or port. Make sure synergy is + running on the server and check for a firewall. +

      +

    • already connected +

      + Check that the synergy client isn't already running. +

      +

    • refused client +

      + Add the client to the server's configuration file. +

      +

    • connection timed out +

      + Check that server-host-name is correct.
      + Check that you don't have a firewall blocking the server or synergy port. +

      +

    • connection failed +

      + Check that server-host-name is correct. +

      +

    +If you get the error "Xlib: No protocol specified" +you're probably running synergy as root while logged in as another user. +X11 may prevent this for security reasons. Either run synergy as the same +user that's logged in or (not recommended) use +"xhost +" to allow anyone to connect +to the display. +

    +When successful you should be able to move the mouse off the appropriate +edges of your server's screen and have it appear on a client screen. +Try to move the mouse to each screen and check all the configured links. +Check the mouse buttons and wheel and try the keyboard on each client. +You can also cut-and-paste text, HTML, and images across computers (HTML +and images are not supported on OS X yet). +

    +

    Step 6 - Run

    +

    +Once everything works correctly, stop all the clients then the server. +Then start the server with the Start button +on Windows and without the -f option on Unix +and Mac OS X. Finally start the clients similarly. On Windows before +clicking Start you may want to set the +Logging Level to +Warning so the logging window doesn't pop +up (because you currently can't close it, just minimize it). +

    +You can also configure synergy to start automatically when your computer +starts or when you log in. See the autostart +guide for more information. +

    +

    Command Line Options Guide

    +

    +Common Command Line Options
    +The following options are supported by synergys +and synergyc. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
     -d,--debug level  use debugging level level
     --daemonrun as a daemon (Unix) or background (Windows)
     -f,--no-daemonrun in the foreground
      --display display  connect to X server at display (X11 only)
     -n,--name nameuse name instead of the hostname
     --restartautomatically restart on failures
     -1,--no-restartdo not restart on failure
     -h,--helpprint help and exit
     --versionprint version information and exit
    +

    +Debug levels are from highest to lowest: FATAL, +ERROR, WARNING, +NOTE, INFO, +DEBUG, DEBUG1, and +DEBUG2. Only messages at or above the given +level are logged. Messages are logged to a terminal window when +running in the foreground. Unix logs messages to syslog when running +as a daemon. The Windows NT family logs messages to the event log +when running as a service. The Windows 95 family shows FATAL log +messages in a message box and others in a terminal window when running +as a service. +

    +The --name option lets the client or server +use a name other than its hostname for its screen. This name is used +when checking the configuration. +

    +Neither the client nor server will automatically restart if an error +occurs that is sure to happen every time. For example, the server +will exit immediately if it can't find itself in the configuration. +On X11 both the client and server will also terminate if the +connection to the X server is lost (usually because it died). +

    +Server Command Line Options
    +

    +

    +    synergys [options]
+
    +The server accepts the common options and: +

    + + + + + + + + + + + +
     -a,--address address  listen for connections on address address
     -c,--config pathname  read configuration from pathname
    +

    +address has one of the following forms: +

    +    hostname
+    :port
+    hostname:port
+
    +hostname is a hostname or IP address of a network +interface on the server system (e.g. somehost +or 192.168.1.100). port +is a port number from 1 to 65535. hostname defaults to +the system's hostname and port defaults to 24800. +

    +Client Command Line Options
    +

    +

    +    synergyc [options] address[:port]
+
    +address is the hostname or IP address of +the server and port is the optional network +port on the server to connect to. The client accepts the +common options. +

    Authentication and Encryption

    +Synergy does not do any authentication or encryption. Any computer +can connect to the synergy server if it provides a screen name known +to the server, and all data is transferred between the server and the +clients unencrypted which means that anyone can, say, extract the +key presses used to type a password. Therefore, synergy should not +be used on untrusted networks. +

    +However, there are tools that can add authentication and encryption +to synergy without modifying either those tools or synergy. One +such tool is SSH (which stands for secure shell). A free implementation +of SSH is called OpenSSH and runs +on Linux, many Unixes, and Windows (in combination with +Cygwin). +

    +

    Configuring the Server

    +Install the OpenSSH server on the same computer as the synergy server. +Configure the OpenSSH server as usual (synergy doesn't demand any +special options in OpenSSH) and start it. Start the synergy server as +usual; the synergy server requires no special options to work with +OpenSSH. +

    +

    Configuring the Clients

    +Install the OpenSSH client on each synergy client computer. Then, on +each client, start the OpenSSH client using port forwarding: +

    +  ssh -f -N -L 24800:server-hostname:24800 server-hostname
+
    +The server-hostname is the name or address +of the computer with the OpenSSH and synergy servers. +The 24800 is the default network port used by synergy; if you use +a different port then replace both instances of 24800 with the port +number that you use. Finally, start the synergy client normally +except use localhost as the server host +name. For example: +
    +  synergyc -f localhost
+
    +Synergy will then run normally except all communication is passed +through OpenSSH which decrypts/encrypts it on behalf of synergy. +

    +

    Tips and Tricks

    +

      +
    • + Be aware that not all keystrokes can be handled by synergy. In + particular, ctrl+alt+del is not handled. However, synergy can + convert ctrl+alt+pause into ctrl+alt+del on the client side. + (Synergy must be configured to autostart when the computer starts + on the client for this to work on the Windows NT family.) Some + non-standard keys may not work, especially "multimedia" buttons, + though several are correctly handled. +

      +

    • + A screen can be its own neighbor. That allows a screen to "wrap". + For example, if a configuration linked the left and right sides of + a screen to itself then moving off the left of the screen would put + the mouse at the right of the screen and vice versa. +

      +

    • + You cannot switch screens when the Scroll Lock is toggled on. Use + this to prevent unintentional switching. You can configure other + hot keys to do this instead; see + lockCursorToScreen. +

      +

    • + Turn off mouse driven virtual desktop switching on X windows. It + will interfere with synergy. Use keyboard shortcuts instead. +

      +

    • + Synergy's screen saver synchronization works best with xscreensaver + under X windows. Synergy works better with xscreensaver if it is + using one of the screen saver extensions. Prior to xscreensaver 4.0 + you can use -mit-extension, + -sgi-extension, or + -xidle-extension + command line options to enable an extension (assuming your server has + the extension). Starting with 4.0 you must enable the corresponding + option in your .xscreensaver file. +

      +

    • + Synergy automatically converts newlines in clipboard text (Unix + expects \n to end each line while Windows + expects \r\n). +

      +

    • + Clients can be started and stopped at any time. When a screen is + not connected, the mouse will jump over that screen as if the mouse + had moved all the way across it and jumped to the next screen. +

      +

    • + A client's keyboard and mouse are fully functional while synergy is + running. You can use them in case synergy locks up. +

      +

    • + Strong authentication and encryption is available by using SSH. See + the security guide for more information. + Synergy does not otherwise provide secure communications and it should + not be used on or over untrusted networks. +

      +

    • + Synergy doesn't work if a 16-bit Windows application has the focus + on Windows 95/98/Me. This is due to limitations of Windows. One + commonly used 16-bit application is the command prompt + (command.exe) + and this includes synergy's log window when running in test mode. +

    Synergy To Do List

    +

    +This page describes the planned development of Synergy. There are +no dates or deadlines. Instead, you'll find the features to come +and the rough order they can be expected to arrive. +

    + +

    Short term

    +

    +Synergy should work seamlessly. When it works correctly, it works +transparently so you don't even think about it. When it breaks, +you're forced out of the illusion of a unified desktop. The first +priority is fixing those bugs that break the illusion. +

    +

    +Some of these bugs are pretty minor and some people would rather +have new features first. But I'd rather fix the current +foundation before building on it. That's not to say features +won't get added until after bug fixes; sometimes it's just too +tempting to code up a feature. +

    + +

    Medium term

    +

    +Some features fit well into Synergy's current design and may simply +enhance it's current capabilities. +

      +
    • Configurable hot key screen switching +
    • Configurable hot key to lock to a screen +
    • Configurable hot key to pop up a screen switch menu +
    • Configure screen saver synchronization on or off +
    • Graphical interface configuration and control on all platforms +
    • Graphical status feedback on all platforms +
    • More supported clipboard formats (particularly rich text) +
    +

    + +

    Long term

    +

    +Two features stand out as long term goals: +

      +
    • Support N computers on +M monitors +
    • Drag and drop across computers +
    +

    +

    +The first feature means sharing a monitor or monitors the way the +keyboard and mouse are shared. With this, Synergy would be a full +KVM solution. Not only would it support a few computers sharing +one screen (still using the mouse to roll from one screen to +another), but it should also support dozens of computers to provide +a solution for server farm administrators. In this capacity, it +may need to support text (as opposed to bitmap graphics) screens. +

    +

    +The second feature would enhance the unified desktop illusion. It +would make it possible to drag a file and possibly other objects +to another screen. The object would be copied (or moved). I expect +this to be a very tricky feature. +

    Synergy Troubleshooting

    +

    Problems

    +
      +
    1. Cannot read configuration +
    2. Connection forcefully rejected +
    3. Connection timed out +
    4. Cannot listen for clients +
    5. Unknown screen name "XXX" +
    6. Server refused client with name "XXX" +
      A client with name "XXX" is not in the map +
    7. Server already has a connected client with name "XXX" +
      A client with name "XXX" is already connected +
    8. Server has incompatible version +
    9. The cursor goes to secondary screen but won't come back +
    +

    Solutions

    +
      +
    1. Cannot read configuration +

      +There's an error in the configuration file. This error is always +accompanied by another message describing the problem. Use that +message and the configuration documentation +to determine the fix. +

      +
    2. Connection forcefully rejected +

      +The client was able to contact the server computer but the server was +not listening for clients. Possible reasons are: +

      +
        +
      • The client is using the wrong server +

        +Make sure the client is using the hostname or IP address of the computer +running the synergy server. +

        +
      • Synergy isn't running on the server +

        +Make sure the synergy server is running on the server computer. Make +sure the server is ready to accept connections. If another program is +using synergy's port (24800 by default) then synergy can't start unless +you specify a different port. +

        +
      • The client is using the wrong port +

        +Synergy uses port 24800 by default but you can specify a different port. +If you do use a different port you must use that port on the server and +all clients. +

        +
      +
    3. Connection timed out +

      +The most likely reasons for this are: +

      +
        +
      • A firewall +

        +A firewall is a program or device that deliberately blocks network +connections for security reasons. Typically, they'll silently drop +packets they don't want rather than sending a rejection to the sender. +This makes it more difficult for intruders to break in. +

        +When synergy traffic hits a firewall and gets dropped, eventually the +synergy client will give up waiting for a response and time out. To +allow synergy traffic through first find all the firewalls on the +network between and on the synergy client and server computers. +

        +A firewall on the server or any network device between the server and +any client should allow packets to TCP port 24800. (Port 24800 is the +default; use whichever port you've selected.) You'll have to consult +the manual for your operating system, device, or firewall software to +find out how to do this. +

        +Usually you'll won't need to adjust a firewall on client machines. +That's because firewalls normally allow incoming traffic on any port +they've initiated a connection on. The reasoning is, of course, if +you started a conversation you probably want to hear the reply. +

        +
      • The network is down or busy +

        +Correct the network problem and try again. You might try +ping to see if the two computers can see +each other on the network. +

        +
      • The server is frozen +

        +If the synergy server is running but locked up or very busy then the +client may get this message. If the server is locked up then you'll +probably have to restart it. If it's just very busy then the client +should successfully connect automatically once the server settles down. +

        +
      +
    4. Cannot listen for clients +

      +Synergy tried to start listening for clients but the network port is +unavailable for some reason. Typical reasons are: +

      +
        +
      • No network devices +

        +You must have a TCP/IP network device installed and enabled to use +synergy. +

        +
      • A synergy server is already running +

        +Check that a synergy server isn't already running. +

        +
      • Another program is using synergy's port +

        +Only one program at a time can listen for connections on a given port. +If the specific error is that the address is already in use and you've +ruled out the other causes, then it's likely another program is already +using synergy's port. By default synergy uses port 24800. Try having +synergy use a different port number, like 24801 or 24900. Note that +the server and all clients must use the same port number. Alternatively, +find the other program and stop it or have it use another port. +

        +
      +
    5. Unknown screen name "XXX" +

      +This error can be reported when reading the configuration; see +cannot read configuration. If the configuration +was read successfully and you get this error then it means that the +server's screen is not in the configuration. All screens must be listed +in the configuration. +

      +A common reason for this is when you haven't used the system's hostname +as its screen name. By default, synergy uses the hostname as the screen +name. If you used a different screen name in the configuration then you +must tell synergy what that name is. Let's say the hostname is +frederick but the configuration defines a screen +named fred. Then you must tell the server +that its screen name is fred by using the +--name fred command line option or setting +the screen name in the advanced options dialog to +fred. +

      +Alternatively, you can specify one name as an alias of another. See +the configuration documentation +for details. +

      +Another common reason for this is a mismatch between what you think the +hostname is and what synergy thinks it is. Typically this is a problem +with fully qualified domain names (FQDN). Perhaps you think your system +is named fred but synergy thinks it's +fred.nowhere.com or +fred.local. You can use either solution above +to fix this. +

      +
    6. Server refused client with name "XXX" +
      A client with name "XXX" is not in the map +

      +The client is using a screen name not in the server's configuration. +This is essentially the same problem as Unknown +screen name "XXX" and has the same solutions: specify another +screen name or add an alias. +

      +
    7. Server already has a connected client with name "XXX" +
      A client with name "XXX" is already connected +

      +This happens when: +

      +
        +
      • Two clients try use the same screen name +

        +Each client must have a unique screen name. Configure at least one +client to use a different screen name. +

        +
      • One client reconnects without cleanly disconnecting +

        +It's possible for a client to disconnect without the server knowing, +usually by being disconnected from the network or possibly by going +to sleep or even crashing. The server is left thinking the client is +still connected so when the client reconnects the server will think +this is a different client using the same name. Synergy will usually +detect and correct this problem within a few seconds. If it doesn't +then restart the server. +

        +
      +
    8. Server has incompatible version +

      +You're using different versions of synergy on the client and server. +You should use the same version on all systems. +

      +
    9. The cursor goes to secondary screen but won't come back +

      +This is FAQ #17 and is also mentioned in +the documentation for using synergy +and configuration. +
