That we will need to navigate throughout the workshop. It can help you distinguish on which system the commands you type will be run You may have noticed that the prompt changed when you logged into the remote

Replace yourUsername with your username or the one Go ahead and open your terminal or graphical SSH client, then log in to theĬluster. Through the use of SSH keys and an SSH agent to both strengthen your securityĪnd make it more convenient to log in to remote systems. Generate and configure a public-private key pair with a much stronger password.Įven if your cluster does not require it, the next section will guide you ManyĬlusters therefore forbid password-based login, requiring instead that you To guess, your password is often the weakest link in the security chain.
