keep SSH connections alive

You connect to a server via SSH, you take a coffee, and when you come back your terminal is stuck. If you are inactive for a while, your connection is cut by the server.

I use a very simple solution. Add this to your ~/.bashrc file:

alias ssh='ssh -o ServerAliveInterval=60'

This way the client sends a null packet to the server every minute, just to keep the connection alive.

You could also do this in different configuration files (see here).
