Python twisted irc - server password on login

Question

I'm trying to create a simple IRC bot in Python using Twisted. I've come pretty far but have encountered a problem when I need to provide the password to enter the server.

I know how to implement a password for joining a specific channel but I have no clue how to provide a username and password upon joining the IRC server itself.

The reason I need to provide a password is that I want the bot to be bouncer-compatible (ZNC).

(Excuse the lousy indentation)

This is what I've tried so far

class BotFactory(protocol.ClientFactory):
"""Factory for our bot"""
protocol = Bot

    def __init__(self, channel, nickname="IRCBot", username=None, password=None):
        self.channel = channel
        self.nickname = nickname
        self.username = username
        self.password = password

    def clientConnectionLost(self, connector, reason):
        print "Lost connection: (%s)" % (reason,)

    def clientConnectionFailed(self, connector, reason):
        print "Could not connect: %s" % (reason,)


if __name__ == "__main__":
reactor.connectTCP("my.irc.server.com", 6667, BotFactory("Channel", "IRCBot", "Name", "Password"))
reactor.run()

I can't find anything in the Twisted documentation about server passwords, only channel passwords. Any help is greatly appreciated!

Take a look at

http://twistedmatrix.com/documents/current/api/twisted.words.protocols.irc.IRCClient.html

I notice the attribute password , with the description:

password =
    Password used to log on to the server. May be None. 

It seems to me you can set password attribute on your Bot class, thus

class Bot(irc.IRCClient):
    def _get_nickname(self):
        return self.factory.nickname

    nickname = property(_get_nickname)
    password = "PASSWORD"

    ...

Does it makes sense? And does it work?

All the best :)
