Using SSH Keys

- > How to use SSH Keys to access the cluster

On Linux :

ssh-keygen -t rsa

ssh-copy-id -i /.ssh/id_rsa.pub username@hepcms-rubin.umd.edu

Then check if you can use it by doing ssh username@hepcms-rubin.umd.edu

OSX:

If you are using macOS Sierra or above, you should already have ssh-copy-id installed. If not, use Homebrew. Then, follow the linux instructions for using ssh-copy-id.

Homebrew

install homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

brew install ssh-copy-id

If you want to copy the key over manually, follow these instructions:

1. Create the key

2. Copy contents of ~/.ssh/id_rsa.pub into the ~/.ssh/authorized_keys file in your home directory on the server. Creating them if necessary.
