How to Keep Alive SSH Sessions (getting rid of the “Write failed: Broken pipe”)

Getting rid of the dreaded “Write failed: Broken pipe”.

Note the difference of ServerAliveInterval/ServerAliveCountMax and ClientAliveInterval/ClientAliveCountMax.

For Mac, Linux and CygWin:

To enable the keep alive system-wide (root access required), edit /etc/ssh/ssh_config; to set the settings for just your user, edit ~/.ssh/config (create the file if it doesn’t exist). Insert the following:

Host *
    ServerAliveInterval 300
    ServerAliveCountMax 2

You can also make your OpenSSH server keep alive all connections with clients by adding the following to /etc/ssh/sshd_config:

ClientAliveInterval 300
ClientAliveCountMax 2
