Keep SSH session alive

sshd (the server) closes the connection if it doesn't hear anything from the client for a while. You can tell your client to send a sign-of-life signal to the server once in a while.

The configuration for this is in the file "~/.ssh/config", create it if the configuration file does not exist. To send the signal every four minutes (240 seconds) to the remote host, put the following in your "~/.ssh/config" file.

Host remotehost:     HostName remotehost.com     ServerAliveInterval 240 

This is what I have in my "~/.ssh/config":

To enable it for all hosts use:

Host * ServerAliveInterval 240 

Also make sure to run:

chmod 600 ~/.ssh/config 

because the config file must not be world-readable.
