Hi Tamara. I've never looked at the IRC module before (and I'm not familiar with the IRC protocol), but could it be as
simple as calling m_reader.Read() in IRCConnector.Connect() and checking for the 004 and 005 responses?
Naturally, you would also need to set ReadTimeout [1] so that an unresponsive IRC server doesn't hang up the method
permanently.
I agree, a Sleep would be an ugly hack and something we want to avoid.
I must admit, the IRC module gets very neglected as I doubt any core developer uses it, but very happy to accept patches
on it. Others who have worked on it in the past might also want to chime in.

Hey All,
I've been meaning to delve into the opensim code for a while now, and
I finally found a starting point.
I think I have found the problem with the IRCBridgeBot module. It
sends the NICK, USER and JOIN commands at the same time, which causes
the JOIN to be ignored, because ircd's need some time to log you in.
This in turn causes the '[IRC-Connector-0]: cannot connect AvaBot29 to
127.0.0.1:5757: Write failure' error, because it doesn't get join
confirmation, at which bridgebot starts to reconnect, starting the
reconnect spam cycle.
It quite simple to solve, bridgebot should wait for the 004, or 005
(even better) response before sending the join command.
See this example of a telnet irc login (with input captured from
ircbridgebot, but timed differently):
:epona.nihlaeth.nl 001 AvaBot70 :Welcome to the AvaIrc Internet Relay
Chat Network AvaBot70

I'd really like to provide a fix for this myself, but I'm afraid I'm
going to need a bit of help with it. Anyone here who wants to help me
get started?
I don't quite understand how the different parts of the module fit
together and communicate. I've identified the spot where the login is
done, but other than building in a sleep (which would be a very ugly
hack), I'm a bit stuck.
I'd really appreciate it!
Kind regards,
Tamara van Haarlem
