29 Oct '20

Hi, today GNU Gatekeeper version 5.6 has been released. Download: https://www.gnugk.org/h323download.html It contains an important bug fix to H.460.19 multiplexing and H.460.26 (media over TCP) when using GnuGk's internal call forwarding (ForwadOnFacility).

GNU Gatekeer 5.2 released
by Jan Willamowius 18 Mar '19

18 Mar '19

Hi, I have just released GNU Gatekeeper version 5.2. You can download it from https://www.gnugk.org/h323download.html This release that has a rewritten networking implementation (aka "large-fdset") that allows GnuGk to scale to higher numbers of calls per server than previous versions. This new implementation replaces the old hack to extend the select() system call by using poll() which enables GnuGk to handle huge numbers of sockets at the same time. The new implementation also works on Windows, but has been tested mostly on the different Unix versions we support. Please note that the relevant configure option when comping GnuGk source code has changed to --enable-large-fdset. There is no need to specify a maximum number of sockets any more. This release also has a few bug fixes, eg. for using LUA scripts with shared libraries and for memory leaks in the error handling of H.235 password authentication. Whats new ? - re-implement LARGE_FDSET using poll(), enable with configure option --enable-large-fdset - ExternalIP is automatically added to the default domains - support running LUA scripts that require dynamic libraries - change default for [TLS] CipherList= to allow elliptical curve ciphers - BUGFIX(gkauth.h) fix memory leak in H.235 password auth - BUGFIX(gkacct.cxx) set known, but unavailable accounting parameters to empty string - BUGFIX(ProxyChannel.cxx) fix setting UDP source IP on Windows when compiled for Vista or higher Enjoy! -- Jan Willamowius, Founder of the GNU Gatekeeper Project EMail : jan(a)willamowius.de Website: https://www.gnugk.org Support: https://www.willamowius.com/gnugk-support.html Relaxed Communications GmbH Frahmredder 91 22393 Hamburg Geschäftsführer: Jan Willamowius HRB 125261 (Amtsgericht Hamburg) USt-IdNr: DE286003584

GNU Gatekeer 4.9 released
by Jan Willamowius 05 Apr '18

05 Apr '18

Hi, I have just released GNU Gatekeeper version 4.9. This version has new features and a few bug fixes. You can download it from https://www.gnugk.org/h323download.html Whats new ? We have 2 new accounting modules: HtttpAcct and AMQPAcct that allow you to send accounting events via HTTP GET or POST to a web service or push them into a RabbitMQ queue. There are also many new accounting placeholders that you can use with any of the accounting modules and there is a new accounting event 'reject' to track calls rejected with ARJ that went unnoticed before. The new RTP inactivity checking allows you to drop calls if there wasn't any RTP activity for a defined amount of time. GeoIP authentication has been significantly updated to support all RAS and all Q.931 messages and to support the new Maxmind database format (GeoIP2). There were also a few bug fixes: - BUGFIX(ProxyChannel.cxx) fix crash while handling RTP packets - BUGFIX(RasTbl.cxx) fix disconnecting unregistered endpoints - BUGFIX(RasSrv.cxx) fix crash in some Avaya endpoints when receiving GCF with a gatekeeperIdentifier - BUGFIX(RasSrv.cxx) fix crash when using IPv6 - BUGFIX(ProxyChannel.cxx) fix handling of CloseLogicalChannel Enjoy! -- Jan Willamowius, Founder of the GNU Gatekeeper Project EMail : jan(a)willamowius.de Website: https://www.gnugk.org Support: https://www.willamowius.com/gnugk-support.html Relaxed Communications GmbH Frahmredder 91 22393 Hamburg Geschäftsführer: Jan Willamowius HRB 125261 (Amtsgericht Hamburg) USt-IdNr: DE286003584
