[Bug 790774] Re: ssh hangs after inactivity (maybe when connection is lost)
And by the way, who set the importance to "Low" should seriously
reconsider.

Title:
ssh hangs after inactivity (maybe when connection is lost)
Status in openssh package in Ubuntu:
Confirmed
Bug description:
Steps to reproduce:
1. Open a terminal
2. Write:
ssh user@xxxxxxxxxx
where myhost.com is some host where you have ssh access and user is the user name
3. Enter the password when prompted
4. Wait for several minutes or hours without doing anything
5. try to type something
Expected: either the connection is still alive, in which case you
should be able to type, see what you type, and do things while logged
on the remote machine, OR the connection has been closed due to
inactivity, in which case ssh should show a message and gracefully
quit.
Observed: ssh hangs; No message is shown; the remote machine's
"prompt" is still shown and the cursor still blinks, but you are
unable to type anything. You can't even quit ssh (typing "exit" has no
effect) and return to normal local terminal operation. The only way
out is to close the terminal (or open another one and kill the ssh
process)
I guess this happens when the connection with the server is lost,
probably closed by the server due to inactivity; however the client
should detect this and gracefully exit.
