ssh config

There’s a way to connect to a server from the commandline without having to remember your username and password off the top of your head. Without having to resort to a password management software also. The way is using an ssh config file, saved in ~/.ssh/config.

# contents of HOME/.ssh/config
Host dev
    User dev

This file means that you can type in ssh dev and log into the server. The first time you do this, you’ll need to enter in your server password.

Next, copy the contents from ~/.ssh/ from your client machine and add it to the end of the file of ~/.ssh/authorized_keys on the server machine. is your public key, by adding it to the authorized_keys file it lets the server know you’re accessing from a trusted computer.

For further information, the online documentation contains the manual for using ssh_config.
