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.

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