Disconnected SSH session

Mac OS X 10.4 Tiger

My SSH session is disconnected after a certain amount of inactivity. How can I avoid that?

Some SSH servers, but also firewalls or other iron between your terminal and the SSH server you are connected to, set a timeout on your session and disconnect it if there is no data transfer. To avoid this, use a command of the form

ssh -o 'ServerAliveInterval 60' ?other options? ?user@??remotehost?

which will trigger the client to send a message to the server through the encrypted channel to request a response from it 60 seconds after the last data has been received.

To configure this permanently for all hosts, add the lines

Host *
  ServerAliveInterval 60

to your ~/.ssh/config (create it if it doesn’t exist yet).
