Raw Blame History

//Released under the terms of the gpl as this file uses a bit of quake derived code. All sections of the like are marked as such
/*
Network limitations:
googletalk:
username: same as gmail (foobar@gmail.com).
FIXME: need to test foobar@googlemail.com
auth mechanism: oauth2(tls+nontls) or plain(tls-only). no digests supported, so mitm can easily grab your password if they use certificate authority hackery, so DO NOT log in from work.
oauth2: I've registered a clientid for use with googletalk's network, but the whole web-browser-is-required crap makes it near unusable. We'll try it if they omit a password.
otherwise a complete implementation.
facebook:
username: foobar@chat.facebook.com
auth mechanism: digest-md5, x-facebook-platform.
gateway implementation: no arbitary iq support (no invite/join/voice).
no roster control
completely untested. I've no interest in signing up to be tracked constantly (but somehow google is okay... go figure... I guess I'm just trying to avoid a double-whammy)
oauth2: no idea where to register a clientid, or what the correct addresses are. a google search implies they don't do refresh tokens properly. sticking with digest-md5 should work.
msn:
username: foobar@messenger.live.com (NOT foobar@live.com - this will timeout)
auth mechansim: x-messenger-oath ONLY
non-standard unusable crap.
uses incorrect certificates. any client that doesn't warn about that is buggy as fuck.
probably doesn't have iq support, no idea, can't log in to test that
requires annoying see-other-host redirection.
no roster control
stun servers are listed in srv records for live.com and messanger.live.com but not messenger.live.com. retards.
oauth2: too lazy to register a clientid. stupid crap. I hate having to register everywhere.
ejabberd:
auth mechanism: digest-md5, scram-sha1, plain.
complete implementation. no issues.
may be lacking srv entries, depends on installation.
may have self-signed certificate issues, depends on installation.
client compat:
googletalk:
implements old version of jingle. voice calls not compatible.
not tested by me.
pidgin:
(linux) has issues with jingle+ice, and can be made to crash. voip uses speex. pidgin's ice seems vulnerable to dropped packets.
(windows) doesn't support voice calls
otherwise works.
