Hello, i connected a server by type 'ssh username@remotehost' in ubuntu's terminal, it works well. But after about 5 minutes, the terminal is freezing, i can not type anything on it. Help me with appreciation.

Hi,

Welcome to LQ!

My first guess is an inactivity time-out, probably caused by firewall rules
anywhere along the route. Does that lock-up also happen if you're active
the whole time, or only after a few minutes of inactivity



Cheers,
