When I open my terminal window I get this:

unknown0025003f3355:~ pontuspersson$ 

Why is this? And How can I fix it?

This question came from our site for professional and enthusiast programmers.

Your system hasn't been given a proper hostname, or has been given the hostname "unknown0025003f3355". Give it a hostname of your preference.

How do you set the host name? – Simon Sheehan Dec 18 '11 at 18:18
    
@SimonSheehan Depends on the OS which the user doesn't mention. – Daniel Beck Dec 18 '11 at 18:19
    
Well let's assume it's Linux, based on how this terminal is setup. Could you provide ways for that? – Simon Sheehan Dec 18 '11 at 18:30
    
@Simon: Which one? – Ignacio Vazquez-Abrams Dec 18 '11 at 18:31
