Overview

To run unattended jobs on a supercomputer log into using a command line or SSH client application installed on your local system.

The ASU supercomputers use your ASURITE login and password to connect.

Examples

SSH for Windows

Do not use SSH through Windows Subsystem for Linux

• The ssh client that is included with the Windows Subsystem for Linux does not work with the Cisco VPN Client and is therefore unsupported.

Powershell

• More recent updates to Windows 10 (and all Windows 11 editions) include ssh from Powershell.

PuTTY

• The recommended SSH client application for Windows is PuTTY

  Use PuTTY to connect to supercomputer with your ASURITE login and password

When you first load putty you should get a screen like below. Creating a new saved session will making connecting easier.

 SSH on Mac or Linux

Mac

• Mac OS X has an SSH client built in

  A simple tutorial on how to use this SSH client can be found here: How To Use SSH on Mac OS X

Linux

• Virtually every Linux distribution includes an SSH client.

  The process for Linux is very similar to a Mac. You have to open a terminal window from which the SSH client will be launched.

  However, the process for launching a terminal window varies from one Linux distribution to the next and is beyond the scope of what we can hope to document here.

SSH command on Mac or Linux

Once you have a terminal window open on your Mac or Linux system, enter the following command, replacing ASURITE with your own ASURITE login name:

ssh ASURITE@login.xxxx.asu.edu

 To log in with X11 forwarding turned on, use the -X option as follows:

ssh -X ASURITE@login.xxxx.asu.edu

Where xxxx is replaced by sol.rc or agave ##

Connecting From Off Campus

If you are connecting from outside of ASU's campus network, you will need to install and launch the Cisco VPN Client before connecting. This may be done through the web (sslvpn.asu.edu) or through an Operating System dependent application downloaded from MyApps (see this discourse post for links).

It is recommended to connect to the following URI which implements two-factor authentication. Instead of sslvpn.asu.edu, instead connect to sslvpn.asu.edu/2fa. In this case, a third field will be required where you must type in one of the following: push, phone, or sms.
