Testing your SSH connection - giobim/Some-help-from-my-Friends GitHub Wiki
After you've set up your SSH key and added it to your GitHub account, you can test your connection.
Before testing your SSH connection, you should have:
- Checked for existing keys.
- Generated a new SSH Key, and
- Added the generated SSH key to node login-node account
When you test your connection, you'll need to authenticate this action using your password, which is the SSH key passphrase you created earlier. For more information on working with SSH key passphrases, see "Working with SSH key passphrases".
- Open a shell
- Enter the following y substituting the address of your Login-Node:
$ ssh -T [email protected]
# Attempts to ssh to Login Node Server
