xmpp-ircd

This is a fork of a fork of a fork of telepaatti, which was originally written as a way for one user to connect to a XMPP server from their IRC client.

This particular fork aims to be ran as an IRC server connected to a single XMPP MUC as a standard XMPP component. This will hopefully allow IRC server operators to migrate to hosting a real XMPP MUC with minimal headache or complaining from hardcore IRC users, and also allow XMPP MUC operators to easily add IRC support.

Usage

./xmpp-ircd.py --muc-server=chat.example.com --component-name=irc.example.com --component-pass=irc

Will connect to 127.0.0.1:5347 and serve the MUC chat.example.com over IRC on port 6667.

prosody for example would need this component configuration for the above command:

Component "chat.example.com" "muc"

Component "irc.example.com"
    component_secret = "irc"

Development

Useful documentation:

• https://tools.ietf.org/html/rfc1459
• https://xmpp.org/extensions/xep-0045.html

Useful command to watch real IRC traffic between actual client and server, connect client to localhost:4444:

socat -v TCP-LISTEN:4444,fork OPENSSL:irc.freenode.net:6697

todo:

• NickServ/SASL auth
• finish /list /whois
• handle XMPP disconnecting
• handle shutdown cleanly
• other IRC commands?

known issues:

• nick changes are hacky, can lock up gajim private messages somehow...
• Nicks are only unique per-channel in XMPP, but per-server in IRC, I don't know that there IS a good solution for this. The main problem this brings up is with private messaging, there is no way to know who you are chatting with. Nick changes are also affected, but that only prevents you from changing your nick in a channel if you are joined with any other channels where the nick is taken.
