• OxIRC
• ServerUpgrade

It's time to upgrade.

http://en.wikipedia.org/wiki/Comparison_of_IRC_daemons has a list of possibilities. Record observations relevant to us here.

1. Our criteria

1.1. Must

• Linux and OpenBSD
• binding to configured address(es)
• binding to configured port(s)
• be packaged for Debian
• support our desired topology
  • probably every server being able to connect to every other server
  • either 3 or 4 servers
• open source
• evidence of being actively maintained
• stable
• SSL (linking)

1.2. Desirable

• SSL (clients)
• some kind of services infrastructure
• configuration but relatively flexible
• not too memory intensive (unlikely to be an issue with our load)
• IPv6 (reason to use hedgehog)
