A simple SSH config file
You can provide ssh with a config file if you’re connecting to many different machines with different ports, user names etc.
Create a file called “config” in your .ssh directory on your machine. This file can contain entries such as
Host Home
User chris
Port 8888
HostName chrisonline.comHost Office
User myseriousname
Port 22
HostName machine.atwork.com
What you can do then is just type “ssh Home”and ssh will automatically pick the right user name, machine and port. This is very convenient if you have different user names on different machines.
