SSH Client Configuration

To simplify the SSH connections, you can add a SSH configuration in your home in ~/.ssh/config:

Host masterX
   Hostname 172.16.100.X0
   User root

Where X represents your cluster number. This then allows you to connect to masterX:

ssh masterX

To avoid having to type in the password every time, you can register your private key on that master using

ssh-copy-id -i ~/.ssh/id_rsa masterX

The first time you connect you will have to type the password, but the second time it will just go into the master directly.
