H323Plus bugs
by Jan Willamowius 08 Nov '19

08 Nov '19

Hi, i fixed 2 possible crashes on Github. A few weeks ago there were also fixes for H.460.22 messages. There is a pending bug that H323Plus is not handling assigned gatekeepers correctly. It always connects to the assigned gatekeeper even if its down instead of staying on the current gatekeeper until the assigned gatekeeper becomes available again. This will need a bigger fix.

GNU Gatekeeper 5.3 released
by Jan Willamowius 26 Jul '19

26 Jul '19

Hi, I have just released GNU Gatekeeper version 5.3. You can download it from https://www.gnugk.org/h323download.html This release has a number of new features as well as some important bug fixes. Whats new ? - LRQ loop detection to optimize calls flows between multiple neighbor gatekeepers This new feature has the potential to significantly reduce the load on all gatekeepers and prevent "LRQ storms". - new routing policy to set call destinations by querying HTTP or REST servers, see [Routing::Http] - much improved support for SNMP - important bug fix for TLS encryption of signaling channels - important bug fixes for H.460.18 (for H.245 tunneling and for multi-homed servers) - performance optimization: this version can handle 5-10% more proxied calls on the same hardware - performance optimization: re-authenticate lightweight, additive registrations only when new aliases differ This significantly reduces the load on password databases. Enjoy! Full change log: - BUGFIX(ProxyChannel.cxx) don't send H.245 address to tunneling H.460.18 endpoint, breaks call when H.245 multiplexing - performance optimization: 5% faster UDP handling - changed default: [SNMP] Implementation=PTlib - remove unfinished Windows-SNMP implementation, use PTLib-SNMP on Windows - support SET and GET-NEXT in PTLib-SNMP - support SNMP sysUpTime when running as standalone agent - BUGFIX(configure.in) LARGE_FDSET defaults to off - new SNMP OID 1.3.6.1.4.1.27938.11.1.9 to query total bandwidth allocated to ongoing calls - BUGFIX(ProxyChannel.cxx) fix hangup when making many TLS calls quickly one after another - BUGFIX(RasSrv.cxx) don't require H.460.22 parameters in ARQs - BUGFIX(ProxyChannel.cxx) fix TLS without LARGE_FDSET - BUGFIX(ProxyChannel.cxx) don't send H.460.22 priority field in SCI - BUGFIX(gkauth.cxx) free memory from cached and expired passwords - re-authenticate lightweight, additive registrations only when new aliases differ - remove switch [Proxy]DisableRTPQueueing, always disabled now - new routing policy: http with config section [Routing::Http] - BUGFIX(ProxyChannel.cxx) fix H.460.18 on multi-homed servers (SCI comes from the correct IP now) - new switch to disable SNMP traps [SNMP] EnableTraps=0 - BUGFIX(ProxyChannel.cxx) don't throw SNMP trap on H.245 connection errors (causes crash under load with Net-SNMP) - BUGFIX(snmp.cxx) shutdown GnuGk when SNMP agent can't be started - BUGFIX(snmp.cxx) protect NetSNMP library calls with mutex - changed default: ForwardResponse now defaults to 1 in [RasSrv::LRQFeatures] and [Neighbor::...] - new feature: loop detection for LRQs [RasSrv::LRQFeatures] LoopDetection=1 - BUGFIX(Neighbor.cxx) some settings in [RasSrv::LRQFeatures] were ignored if not set in [Neighbor::...] -- 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 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

Help
by lewei zhuang 29 Jul '18

29 Jul '18

Dear H323plus Team: I think I need some help that when I use the simph323,it can't use the H.264 in my ubuntu 16.04,and the sound device is NO Audio . I wanted to found the solutions by Google ,but I can only found I need to install libavcodec and alsa .so I do it. And the sound output device can be found ,but the sound input device still NO Aduio. In my ubuntu 16.04 ,I had install all about alsa ,and I install libavcodec-dev and ffmpeg ,but it doesn't work. The error message is as follows Sound output device: "alsa_output.pci-0000_02_02.0.analog-stereo" Sound input device: "Null Audio" checking for LIBAVCODEC... yes configure: libavcodec stack align hack disabled checking for h263p_encoder in -lavcodec... no checking for h263p_encoder in -lavcodec... (cached) no checking for mpeg4_encoder in -lavcodec... no checking for h264_decoder in -lavcodec... no

H.239 bug fixes and improved test tools
by Jan Willamowius 25 Jul '18

25 Jul '18

Hi, if you are using H.239, you should update to the latest code from Github. A number of bugs have been fixed in the H.239 code recently. If you still see issues, please let me know. https://github.com/willamowius/h323plus As part of the H.239 testing, I also added H.239 support to the call generator (--h239enable) as well as RTP fuzzing (--fuzzing). Its amazing how many commercial H.323 endpoints crash when you apply some RTP or RTCP fuzzing. ;-) https://github.com/willamowius/callgen323 Regards, Jan -- Jan Willamowius, H323Plus maintainer EMail : jan(a)willamowius.de H.323 Support: https://www.willamowius.com/h323plus-support.html Relaxed Communications GmbH Frahmredder 91 22393 Hamburg Geschäftsführer: Jan Willamowius HRB 125261 (Amtsgericht Hamburg) USt-IdNr: DE286003584
