A small guide to install identd server, and get rid of the ~ in front of your username at irc (was annoying me, couldn't get on efnet).
First of all you need to open port 113/TCP in your router.
sudo apt-get install oidentd
You should get
Starting ident daemon: oidentd.
when finishing installing it.
else you can manually start it by typing
in a terminal
That should be it.
If you are using the Firestarter firewall, remember to add port 113 to your rules.
