Logging In and SSH Keys

In order to log in to the LCRC clusters, you will need to set up SSH Keys. SSH (Secure SHell) is a network protocol that provides a secure way to access a remote computer. Depending on your operating system, you may or may not have to install a third-party SSH client in order to log in.

LCRC currently runs 2 clusters, Bebop and Blues. Following the directions below, you may interchange the cluster name based on your needs as they both use the same SSH keypair and filesystems.

macOS / OS X

Apple’s operating system comes with the OpenSSH client. To use it, you’ll need to use the Terminal application. Open Spotlight by pressing Space, type “terminal”, and hit Return to launch Terminal. You can now follow the generic OpenSSH setup instructions to create your SSH key pair and log in.

Linux / Unix

Most modern Linux and Unix distributions come with OpenSSH or a similar SSH client. To check, open up a terminal and run the following command (with a capital V):

$ ssh -V
OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013

It should print out the name and version of the client. If it says OpenSSH, you can follow the generic OpenSSH setup instructions to create your SSH key pair and log in. If you have a different SSH client, shoot us an email at support@lcrc.anl.gov and we can help you get set up.

Windows

Unfortunately, Windows does not come pre-installed with an SSH client. You will have to install your own. Most of our users use the PuTTY SSH client to log in. See our PuTTY setup instructions to get started.

Other

If you are running an operating system that has not been mentioned above, or you want to try a different SSH client, shoot us an email at support@lcrc.anl.gov and we can help you get set up.
