I am installed Ubuntu on Virtual Box, and use xshell (a remote terminal application) to ssh to ubuntu. when I hibernate computer during night, after powering it on, the session is expired and I should to ssh to ubuntu again. Is there is way to configure ssh to nut expire during hibernation or after hours of ideal connection? I use Fedora to, if configs have differences please mention it.I use Windows 7. 
disabling ssh session expiration
ubuntu;ssh;virtualbox;virtual machine
Try tmux. On the server side:sudo apt-get install tmuxAfter logging in, start tmux.tmuxIf the connection breaks, log in again via ssh and reconnect the tmux session. To discover the session number:tmux lsThe output might be something like this:0: 1 windows (created Wed Jan 9 12:27:40 2013)Connect to the tmux numbered session like this:tmux attach -t 0Then you are right back where you left it.
