  • support for redis as database (eg. as backend for password storage)
  • Bug fixes:
  • important fix for H.245 tunneling translation with H.460.18 endpoints
  • fix for snmpwalk in PTLib-SNMP implementation

New in OpenH323 Gatekeeper 5.3 (Jan 7, 2020)

  • 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 monitoring
  • 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.

New in OpenH323 Gatekeeper 5.2 (Jul 26, 2019)

  • 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.
  • 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.

New in OpenH323 Gatekeeper 4.0 Beta (Oct 10, 2015)

  • New H.235 implementation (password authentication):
  • now GnuGk is able to verify every RAS and Q.931 message from the endpoint and will add securiry tokens so the endpoint can verify every message it gets from gnuGk
  • since implementations vary widely, GnuGk supports a number of compatibility switches in the [H235] section

  • bug fixes, including a crash and hanging status port on Windows servers
  • a new IP/port detection algorithm for endpoints behind NAT that works well even with unregistered (!) endpoint
  • neighbor pings to speed up call routing if your neighbors are frequently down
  • geo-blocking: with the GeoIPAuth policy, you can allow or block calls based on the location of the IP
  • status port event back log: When you connect to the status port to diagnose an issue, the relevant events are already gone. With this new feature you can tell GnuGk to save the last n events and show them later on. This way you can take a look at eg. the last 100 failed registrations etc.
  • QoS DiffServ marking for RAS, H.225 and H.245 messages (based on patch provided by Vidyo) Now you can set the DiffServ class for signaling messages. Previously you could only mark RTP packets.
  • support for H.235.TSSM: H.235 needs time synchronization between gatekeeper and endpoints and the proposed H.235.TSSM standard provides a means for endpoints to detect that they are not in sync with the gatekeeper and apply a time offset.

New in OpenH323 Gatekeeper 3.8 (Jan 3, 2015)

  • In response to the current wave of H.323 spam / hacking GnuGk 3.8 has a number of improvements to security related features:

  • GnuGk is now using better random numbers in security relevant places
  • new authentication modules using LUA scripts called LuaAuth
  • new switch [RasSrv::ARQFeatures] CheckSenderIP=1 to make sure ARQs come from the same IP as the initial registration
  • FileIPAuth is now able to check ARQ messages
  • AliasAuth updated to work with H.460.18 endpoint
  • PrefixAuth was extended to support unregistered calls
  • SQLAuth can now operate on SrcInfo fields using %{SrcInfo}
  • improvements to the addpasswd utility.
  • Other new non-security related features include:
  • The CatchAll policy now rewrites the destination alias which makes it easier to send CatchAll calls to MCU rooms.
  • You can now filter out whole capability classes, eg. all video or H.239 capabilities if some of your endpoints have trouble handling them
  • A new switch [Gatekeeper::Main] MinH323Version= lets you set the H.323 version GnuGk identifies itself as using (up to the latest version 7). This is mainly to deal with endpoint that switch features when they believe they are talking to older endpoints (which one shouldn't be doing...)
