Name your servers.

If your day involves ssh-ing into various servers, you know how cumbersome is to type all that details again and again. When the number becomes large, you tend to confuse between host names, IPs and usernames.

But, ssh allows you to alias them into cute nicknames you prefer.

The configuration file needed to be edited is ~/.ssh/config.

Host server
User user

Now all you have to do is

$ ssh server
