I use Media Temple ssh 5-10 times a day, that’s why typing in

ssh serveradmin@positivesum.org@s43472.gridserver.com

and then entering password is way too slow.

There is a better way.

To login, I use 

ssh ps

ps – is acronym for positivesum.org

In this tutorial, I will explain to you how to set this up.

First, I will address the the Password-less SSH login and then I will tell you how to setup the acronym.

Password-less SSH Login

1. You need Public Key (run ssh-keygen if you haven’t already)
2. in your ~/.ssh folder you will have a id_rsa.pub
3. you need to copy this file to your mediatemple ssh
   scp ~/.ssh/id_rsa.pub serveradmin@yourdomain.com@yourdomain.com:~/.ssh
   should do the trick
4. now ssh into your media temple
   ssh serveradmin@yourdomain.com@yourdomain.com
5. run
   cd ~/.ssh
6. now to add your key to list of authorized_keys run
   cat authorized_keys id_rsa.pub > authorized_keys2
7. and replace old list with new list
   mv authorized_keys2 authorize_keys
8. run change mod to protect your authorized_keys file
   chmod 600 authorized_keys
9. now you should be able to logout
   exit
10. and log back in without requiring to enter a password.

Acronym instead of your domain name

1. with vim(or your favorite command line editor) edit ~/.ssh/config,
   vim ~/.ssh/config
2. add
   Host ps
        HostName s43472.gridserver.com
        User serveradmin@positivesum.org

lines after Host ps have to be indented You have to replace ps with your own acronym(whatever is applicable in your case) and change the HostName and User to your hostname and user name. You can create as many of these entries as you would like for all of your servers.

Here your go, this should work, if it doesn’t let me know in the comments.
