Lot of times my ssh session get broken because I didn’t do anything for a while. Sometimes I have started “top” just that the connection does not get broken because of inactivity. But this is not really what I wanna do everytime. Luckily the SSH client can be configured to send alive telegrams for every session so that you do not need to pass arguments every time you open a SSH conneciton.

Following settings will make the SSH client to send alive telegrams to the other side every 60 seconds, and give up if it doesn’t receive any response after 2 tries.

~/.ssh/config
Host *
    ServerAliveInterval 60
    ServerAliveCountMax 2
