* Added support for UltraVNC Single Click as originally proposed by Noobius ↵Monkey2012-04-231-0/+8
| | | | | | (Boobius) on 6/1/11. Original thread: http://sourceforge.net/tracker/?func=detail&aid=3310255&group_id=32584&atid=405860

* Add the OpenSSL libvncclient TLS version to the build system.Christian Beier2012-04-144-1/+657

* IPv6 support for LibVNCServer, part four: add copyright notices to files ↵Christian Beier2012-04-022-0/+2
| | | | with non-trivial changes.
* IPv6 support for LibVNCServer, part three: make reverse connections ↵Christian Beier2012-03-103-12/+129
| | | | | | | | IPv6-capable. Besided making libvncserver reverseVNC IPv6-aware, this introduces some changes on the client side as well to make clients listen on IPv6 sockets, too. Like the server side, this also uses a separate-socket approach.
* Add an optional parameter to specify the ip address for reverse connectionsLuca Stauble2012-02-033-3/+21
| | | | | | | | | | | | | | | | For security reasons, it can be important to limit which IP addresses a LibVNCClient-based client should listen for reverse connections. This commit adds that option. To preserve binary backwards-compatibility, the field was added to the end of the rfbclient struct, and the function ListenAtTcpPort retains its signature (but calls the new ListenAtTcpPortAndAddress). [jes: shortened the commit subject, added a longer explanation in the commit body and adjusted style] Signed-off-by: Luca Stauble <gnekoz@gmail.com> Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
* When GetCredential() callback is not set, don't use authentications ↵Christian Beier2011-11-091-2/+2
| | | | | | | requiring it. The auth methods that employ Getcredential() will only be used if the client's GetCredential callback is actually set.
* Replace deprecated GnuTLS functions gnutls_*_set_priority with ↵Vic Lee2011-04-271-9/+6
| | | | | | | | | | | | | gnutls_priority_set_direct. The functions gnutls_*_set_priority we used were marked deprecated since latest GnuTLS version 2.12. However the replacement function gnutls_priority_set_direct is available since 2.2, which is even lower than our version requirement 2.4 in configure. The patch just replace the deprecate function to fix the compile warning. Signed-off-by: Vic Lee <llyzs@163.com> Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
* Fix regression in Ultra encoding introduced by commit ↵Christian Beier2011-03-171-2/+2
| | | | | | fe1ca16e9b75b5f38ab374c8dfff92d2c3ea4532. My bad. There we see what the encodings test is good for ;-)
* Remove useless comparisons that always evaluate to false.Christian Beier2011-03-171-6/+1
| | | | | There can not be more than 255 security types and MSLogon is RFB 3.6 only.

* Fix libvncclient TLS for Windows builds.Christian Beier2011-03-121-5/+39

* Update minilzo library used for Ultra encoding to ver 2.04.Christian Beier2011-02-261-1/+1
| | | | | | | | | | According to the minilzo README, this brings a significant speedup on 64-bit architechtures. Changes compared to old version 1.08 can be found here: http://www.oberhumer.com/opensource/lzo/lzonews.php Signed-off-by: Christian Beier <dontmind@freeshell.org>

| | | | | | | | | No functional changes. All files used by _both_ libvncserver and libvncclient are put into a 'common' directory and references from other files as well as Autotools and CMake build systems are updated. Signed-off-by: Christian Beier <dontmind@freeshell.org>
* libvnc[server|client]: implement xvp VNC extension.Christian Beier2010-11-021-0/+52
| | | | | | | This implements the xvp VNC extension, which is described in the community version of the RFB protocol: http://tigervnc.sourceforge.net/cgi-bin/rfbproto It is also mentioned in the official RFB protocol.
* Only define strncasecmp to _strnicmp when using MS compiler.Christian Beier2010-10-211-5/+1
| | | | | | | Redefining strncasecmp to _strnicmp makes libvncclient hang forever in SetFormatAndEncodings() on Windows when built with MinGW64. Reported by Tobias Doerffel <tobias.doerffel@gmail.com>, thanks!
* Fix build failure wrt IP QoS support in libvncclient.Christian Beier2010-10-201-1/+1
| | | | | | This is a small addendum to 0797e42a4aaf8131ae71899faea2d682ed81cb59. Seems that having IPv6 support in the OS does not necessarily mean that IPV6_TCLASS is available. One such case seems to be Mac OS X 10.5.

* IP QoS support in libvncclient.Christian Beier2010-09-293-0/+56
| | | | | | | | | | This enables setting the DSCP/Traffic Class field of IP/IPv6 packets sent by a client. For example starting a client with -qosdscp 184 marks all outgoing traffic for expedited forwarding. Implementation for Win32 is still a TODO, though. See http://betelco.blogspot.com/2009/03/dscp-marking-under-windows-at.html for an overview of the Win32 QoS API mess...
* Non-blocking sockets for Windows.Christian Beier2010-09-131-6/+9
| | | | | | | | | | | Expands the SetNonBlocking() function in libvncclient/sockets.c to also work under Windows and also changes it to honour maybe already present socket flags. A similar function was introduced for libvncserver as well and all the #ifdef'ed fnctl calls replaced with calls to that one. Signed-off-by: Christian Beier <dontmind@freeshell.org>
* Fix MinGW32 compilation with libjpeg.Christian Beier2010-09-061-0/+3
| | | | | | | | | MinGW32 (or more exactly, a rpcndr.h file included by winsock2.h) typedefs a 'boolean' type that jmorecfg.h included by jpeglib.h also tries to typedef. So, tell the jpeg headers. Closes: 3007302

* Call MallocFrameBuffer before SetFormatAndEncodingsWouter Van Meir2010-06-041-3/+3
| | | | | | | | | | | | The hook is still called after InitialiseRFBConnection() so we can choose the color settings depending on the vnc server (or settings) in that hook. This way one can use the "VNC server default format" pixelformat if the client supports it, or perform a workaround (Intel AMT KVM "classic vnc" server only works using 8bit colors in RFB3.8) Signed-off-by: Wouter Van Meir <wouter.vanmeir@pandora.be> Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

| | | | | | | | | | | | required It seems that vino does not send AuthOK when there is no password with anonymous TLS, and it seems that vino is the only <3.8 VNC server that handles anonymous TLS at all, so let's not wait for the packet that will never come.

* Fix checks for socket values, 0 is a legal value.Christian Beier2009-11-113-4/+7

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Forking the whole process from deep within a library call does not really work at all with apps that use multiple threads, i.e. every reasonably modern GUI app. So, provide a non-forking listen function so that the caller can decide if to fork, start a thread, etc. This implementation adds a timeout parameter to be able to call the listen function multiple times so that it's possible to do sth. else in between, e.g. abort listening.

* | Fix hostname resolution problems under WindowsAlexander Dorokhine2009-10-301-8/+17
| | | | | | | | | | | | | | | | On Windows, the WSA system needs to be initialized to be able to look up host names. This patch also changes *addr = 0 to use the constant INADDR_LOOPBACK instead, which seems to be required on Windows.
