tmux and irssi

Grenzland Club has both tmux and irssi. With these two, you can connect to our Grenzland chat and stay online indefinitely, even if you are not logged in to the remote machine. See the irssi tutorial for an introduction to irssi.

The tmux and irssi integration works like this:

1. connect to grenzland.club:
   ssh
   Or if your connection is bad:
   mosh
2. on grenzland.club:
   tmux
3. within tmux:
   irssi
4. within irssi:
   /set nick your_name
   Pick a nickname you want to use.
5. continue within irssi:
   /connect grenzland
   This network comes predefined if you’re on grenzland.club.
6. and finally, still within irssi:
   /join #welcome

When you’re done chatting, you don’t quit. Instead, you detach from tmux so it continues running in the background, keeping your irssi session alive. It does that even if you close the connection to grenzland.club.

To detach from your tmux session, press Ctrl B (the prefix key) and then press d (to detach). Now you can use exit to leave tmux and another exit to leave ssh or mosh.

Ctrl B is the key reserved for tmux. This makes Emacs users sad.

Later, you want to attach to that tmux session again:

1. connect to grenzland.club using ssh (or mosh if your connection is bad)
2. on grenzland.club, run tmux attach to attach to the running sessions

And you’re back!

If you really want to quit your irssi session:

1. issue the irssi command /quit
2. issue the tmux command exit
3. issue the shell comand exit to quit the shell and end ssh or mosh
