Changing the name in terminal

[stormbob]

I have a problem.
I have a terminal looking like this. Before it was storm-2, at the first name, and then storm as the second.
I played abit around, found the advanced settings in the profile and changed the shortname to 'csl' in hope it was "storm-2" but no. Now i got storm-2 and csl, thats fine execpt - how do i change "storm-2"?!

Storm-2 is your host name. This can be changed under the SYSTEM Preferences >> Sharing.
