Our shell gateways, reachable worldwide from anywhere on the internet, provide text-only shell access to your network account. (Once on the gateway, you can also connect to other machines in our building network.)

  • Faculty/visitor/staff shell gateway: ssh -p 31415 dragon.math.arizona.edu
  • Graduate student shell gateway: ssh -p 31415 phoenix.math.arizona.edu

You use ssh to connect to our shell gateways.SCP, and SFTP are also used to transfer files between your network account and other systems.

Your SSH program uses port 22 by default. You will need to set it to use port 31415 when you are not in a Math building. 


Please never run heavy-duty computations directly on the shell gateway. If you are running a compute job you should ssh or VNC to another machine (such as your office desktop, or the chivo cluster for graduate students)

Different ways to connect to the shell gateway:

  • If you are running Microsoft Windows download putty:
    • PuTTY [Download], [How to use]
      This elegant tiny SSH client is a quick download and does not require an Installer to be run.
  • If you are running Linux or Mac OS X, you can run ssh from the command line, e.g.:
    ssh -p 31415 accountname@dragon.math.arizona.edu

Gateway authentication:

To verify that you are not being duped by a rogue gateway, the first time you try to connect you will be presented with the gateway's RSA or DSA key fingerprint. The correct fingerprints are:
