SSH Time Saver

If you’re logging into several SSH terminals throughout your work day, here’s a quick client config change that will save you some keystrokes:

Add the following to your local ‘~/.ssh/config’

Host *
ControlPath ~/.ssh/master-%r@%h:%p
ControlMaster auto

Once you’ve logged into a server, open another terminal and log in again to the same server with the same username. You won’t be prompted for a password as it logs in over the existing socket that is created from your first session. Downside, if you lose the first terminal you lose all the others.
