ssh has a great config file for the client that is rarely used by most folks, but can make life a lot easier with just some minor knowledge. For example, here is a .ssh/config file from my home directory that says anytime I connect to this website, connect as a user other then my default and alias that host to be “www” instead of cyborgworkshop.org .
Host www
HostName cyborgworkshop.org
User Remote_User
now if I just run
ssh www
it’s the same as running
ssh Remote_User@cyborgworshop.org
It doesn’t stop there though, you can specify key files to use, encryption and compression, etc. Man ssh_config for more shtuff!
