To request class accounts, please email Dr. Brian G. Olson.

Required Program (SSH)

The suggested method for connecting to the Magnolia cluster is to use ssh. This is the standard method for connecting to linux machines, for more details google 'how to ssh into a linux machine'

Fingerprint

When first connecting to a computer with ssh, you will be presented with a fingerprint. This is used to verify that you are connected to the correct computer. The current list of SSH fingerprints for Magnolia can always be found on the SSH_Fingerprints/magnolia.usm.edu page. If the fingerprints do not match, please contact Dr. Brian G. Olson

Connecting / Login

The following shows how to connect to the Magnolia cluster from three (3) common operating systems: Linux, Windows, and OS X.

Note
For the following, replace <username> with the username you were assigned.

Linux

Open a terminal, and type the following:

user $ssh <username>@magnolia.usm.edu
The authenticity of host 'magnolia.usm.edu' can't be established.
ECDSA key fingerprint is SHA256:glQIZZKlsAwf3QJNNDQSxFpRzE2rKs4GfxByO6ZBzis.

Are you sure you want to continue connecting (yes/no)?

If the fingerprint matches one listed on SSH_Fingerprints/magnolia.usm.edu, type YES followed by Enter.

Full Login Procedure

The full login procedure, for a user named exampleuser, should look like the following:

user $ssh exampleuser@magnolia.usm.edu
The authenticity of host 'magnolia.usm.edu' can't be established.
ECDSA key fingerprint is SHA256:glQIZZKlsAwf3QJNNDQSxFpRzE2rKs4GfxByO6ZBzis.

Windows

Install an SSH client, like PuTTY (www.putty.org) or MobaXTerm (mobaxterm.mobatek.net). MobaXTerm is recommended for users who want to run GUIs that use X11 forwarding, and PuTTY is recommended for users who only need text environments. The following explains how to connect with PuTTY, but similar settings can be used for connecting with MobaXTerm. Run PuTTY, and type magnolia.usm.edu in the Host Name field, outlined in orange in the figure, then click on Open

If the fingerprint matches one listed on SSH_Fingerprints/magnolia.usm.edu, click on YES, and you'll see the following screen:

From here, the output should be nearly identical to the full login procedure.

OS X

Open the Terminal application, and type the following:

user $ssh <username>@magnolia.usm.edu

If the fingerprint matches one listed on SSH_Fingerprints/magnolia.usm.edu, type YES followed by Enter.
