How to Create an SSH Shortcut

nano ~/.ssh/config                                                                                                              

Host plexserver 
    HostName 10.0.0.251 
    User plex 
    Port 9022 

Host citron 
    HostName 10.0.0.165 
    User citron 
    Port 22 

Now, you can simply SSH into any of these servers with these simple commands:

ssh plexserver
ssh citron

If this isn’t working for you, trying changing the permissions of the config file like this:

chmod 600 ~/.ssh/config
