HOWTO: Set the SSHD Idle Timeout

Here's something that I usually forget to change from the default and then get annoyed when my terminal hangs.
  1. As root open your sshd_config file in an editor.
    su -  
    vim /etc/ssh/sshd_config  

  2. Add the following lines.
     ClientAliveInterval 600  
     ClientAliveCountMax 3

  3. Restart the sshd process.
     service sshd restart
That's it. That will keep you logged in for 30 minutes at a time without activity. (600 seconds x 3)
