ssh

I have a webserver running a number of websites.

When I ssh in, it gives me a tab name of [email protected], which is counterintuitive, making it seem like those tabs are on my localhost.

I would like to change the hostname, but I want to be sure that it won't break anything else.

So for what purposes does that hostname string get used, and how can I be sure that it won't affect any functioning systems?
