Logging In

Interaction with the Office of Research Computing systems is typically performed with command line tools. The command line tools can be run via a command prompt, also known as a shell. SSH is used to establish a secure shell.

Users should log in using ssh to the hostname ssh.rc.byu.edu

Programs can be tested from the interactive nodes, but most programs left running for more than an hour will be killed automatically (exceptions include scp, tar, wget, and similar programs). Read the Slurm documentation when you are ready to run your jobs.

Windows

Beginning with newer versions of Windows 10, you can install OpenSSH Client in Windows 10 and use SSH from Powershell. For more information, see Microsoft's documentation, especially the section about installing OpenSSH client.

Older versions of Windows do not have SSH capabilities built-in. Download PuTTY or Bitvise Tunnelier. Enter hostname: ssh.rc.byu.edu. Click connect and enter your username and password when prompted. Once connected you can run commands.

Linux / Mac OS

Linux and Mac OS have SSH built-in. The terminal can usually be found in one of three locations: Applications -> Utilities, Applications -> Accessories, or Applications -> System Tools. This opens a command prompt on the local system; you can now connect to ssh.rc.byu.edu. Run

$ ssh username@ssh.rc.byu.edu # replace 'username' with your username
