A bit of a noob question.
I have a letshost VPS (running Ubuntu 11.10) that I am using to learn about web programming. My problem is that if a terminal is left inactive for about 10 minutes it disconnects, which is annoying as I like to keep 3 or 4 shells
open, but some of them I only need to use infrequently. I know that this
is not a problem with my ssh client as I don't experience this problem on
other servers. Is this something that I can easily fix - is there some setting
that determines how long a shell can be inactive for?
