04 Mar '21

Dear community, GNU Gatekeeper version 5.7 has been released. Download: https://www.gnugk.org/h323download.html This version has some important bug fixes, improves interoperability with other vendors and also has a few new features. Bug fixes: - several severe crashes and a few memory leaks have been fixed Improved interoperability with: - Lifesize endpoints - Poly's Microsoft Teams gateway - Polycom RealPresence Capture Server New features: - You get a warning in the GUI / on the status port if one of your endpoints has an incorrect time setting and this password authentication fails. This makes trouble shooting a lot easier. - Invalid TPKT packets (eg. due to network errors) now don't necessarily take down an otherwise healthy call. Use the new AbortOnInvalidTPKT=0 switch to enable. - You have a new %{Vendor} variable for SqlAuth RegQuerys and LuaAuth Full change log: - BUGFIX(ProxyChannel.cxx) fix crash on non-standard H.245 Indication from Polycom RealPresence Capture Server - BUGFIX(ProxyChannel.cxx) fix possible crashes on non-standard generic information in OLCs - print warning message on status port when passwords get rejected due to wrong time - BUGFIX(httpacct.cxx) fix memory leak - BUGFIX(ProxyChannel.cxx) fix possible crash - BUGFIX(gk.cxx) avoid crash when terminating in the middle of program startup, set non-zero exit code so restarter notices error - return unused memory back to OS periodically - new switch: [RoutedMode] AbortOnInvalidTPKT=0 for more graceful handling of network errors - BUGFIX(gk.cxx) fix for running on Alpine Linux (needs updated PTLib, too) - don't start GnuGk if RTP multiplexing is configured, but we can't start the listener - new switch: [RoutedMode] MatchH239SessionsByType=0 to fix presentations with LifeSize endpoints over Poly's Microsoft Teams gateway - BUGFIX(ProxyChannel.cxx) make sure we don't set RTP address on multiplexed RTCP keepalive - BUGFIX(RasSrv.cxx) look at all tokens for H.235.TSSM - add %{Vendor} variable for SqlAuth RegQuery and LuaAuth Regards, Jan -- 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

Compiling GnuGk / H323Plus / PTLib on Alpine Linux
by Jan Willamowius 20 Nov '20

20 Nov '20

Hi, while GnuGk, H323Plus and PTLib work on virtually all Linux distributions, there is one notable exception: Alpine Linux. This is because Alpine uses musl libc instead of GNU libc, which lacks many features and our PTLib won't compile with it. Solution: Stick with any other Linux distribution (Debian, CentOS, Fedora etc.) or your choice of *BSD, Solaris or Windows.
