Full hostnames with ssh config

I frequently use my laptop from home, where I have to get into my work network via VPN.

Because of some particulars of our VPN setup, the general domain of my computer isn't set up over VPN as it would be when I'm physically at work. Meaning, if at work I could connect to the dev server with a simple ssh dev, from home I need to do a full hostname, ssh Even when on the VPN.

Fortunately, ssh's config file can save my poor brain a little context-switching by knowing the full hostname for any shortname I might need:

Host dev

Now I can ssh dev both places, and not be concerned with remembering the full name depending on where I am.


You can combine this with the "User" property if you routinely need to use a username other than your default.

Host dev
User pablo

Would log me into the dev server as the username pablo instead. Pretty nifty!
