OpenSSH provides a per-user configuration file usually located in ~/.ssh/config. This file can help ease your life as Sysadmin. Let’s say that you frequently connect to a server in this way:
ssh admin@boring-servername.boring-domain.com
With OpenSSH there is an easy way to do the job. Edit or create a config file:
vi ~/.ssh/config
and then add the following:
Host servername
User admin
HostName boring-servername.boring-domain.com
Where Host is the alias for the remote server you want to connect to, HostName is the full name of the remote server and User is the login name.
