ULYSSIS hosts its own IRC server. (IRC stands for Internet Relay Chat, IRC on wikipedia)

Contact us on IRC

The public channel is simply called ulyssis, if you have a question, you can use IRC as a fast way to contact us. Details:

Channel: #ulyssis

To use IRC you'll need an IRC client, we advise the terminal based irssi for Linux (just use sudo apt-get install) and mIRC for Windows, but there are a lot of other free options.

Using our web IRC client

If you won't regularly use our IRC or if you just want to check it out, you can use our web IRC client instead. You can find it at

Using irssi in a Screen

Our IRC server isn't very crowded and as you only see messages when you're connected, we advise you to run irssi in either a screen or a tmux session. Members can run screen or tmux on our shellservers, as they keep running 24/7 you can use them to keep track of your conversations. Screen and tmux are similar programs. Screen has been around for longer and is more tested, while tmux is more modern with new features and being easier to use for beginners.

Connect to the shellserver

Use the ssh command in your Linux or OS X terminal, or use PuTTY to connect on windows. Extensive information on how to do so can be found on Accessing shell servers over SSH.

Start irssi in a screen

  • When on the shellserver, enter screen to start a screen session, or tmux to start a tmux session.
  • Enter irssi to start irssi.
  • Connect to the IRC server: /server
  • Connect to the public channel: /join #ulyssis

Screen usage

  • To exit the screen: press Ctrl-A and press D ('detach') to return to the shellserver.
  • To reconnect: enter screen -r or screen -DR (the latter will create a new screen if it wasn't already made).

Tmux usage

  • To exit the tmux session: press Ctrl-B and press D ('detach') to return to the shellserver.
  • To reconnect: enter tmux attach

Help, I can't reconnect to my session!

  • Check if you are on the right shellserver and didn't make a typing error.
  • If everything is correct, your screen may have been stopped by a crash of our shellserver. You can check the status section of our website for more information about possible downtimes.
  • Make sure you use the right program (screen if you started a screen session and tmux if you started a tmux session)
