How to name ssh connection

Question

I have an SSH connection that I can open without password. I have to name that connection so I can use it like

ssh server

How could I do that?

Answer 1

Put this in your ~/.ssh/config:

Host server
Hostname actualServerNameOrIp
User yourUserName

Of course, replace server with the name you want to type when you ssh server, actualServerOrIp with the actual server name or IP address and yourUserName with the name of the user you're allowed to login with on that server.
