This is probably the most stupid question ever but what has happened to my ssh connection?

It is suddenly in color, has that bar across the bottom and looks completely different. Is it caused by a running service that I can stop? (It is a Ubuntu server)

ssh connection

Apologizes if this is a ridiculous question.

What happens if you press Ctrl-a, then '?' (literal question mark)? – Andrew Jul 27 '12 at 0:04
@Andrew Having been researching I think I have enabled tmux. Do you know how I remove it? Thanks. – John Wheal Jul 27 '12 at 0:08
@JohnWheal Press "Ctrl+b x", it will close your tmux panel on – Denis Jul 27 '12 at 0:23

Looks like you've run tmux, log out if you don't want to remain there. Although it carries a lot of benefits.


If it's already there when you log in, it's either run from your one of your shells start files, e.g. $HOME/.bashrc in bash, or it is your login shell, check with: grep "^$USER" /etc/passwd.
