Install two pieces of software on your Windows machine.  The first is
an SSH client, I would recommend the one from ssh.com, other ssh
clients will work.  Download and install:

http://ftp.math.utah.edu/pub/ssh/SSHSecureShellClient-3.2.9.exe

Next a VNC client (download and install the free VNC Viewer for
Windows):

http://www.realvnc.com/

Once these two are installed, start the "SSH Secure Shell Client"
program.  Go to "Edit Profiles", select the default profile and enter
the host to go to such as "sunbelt.math.utah.edu" (there are seven
other hosts you could choose from).  Choosing a specific host, makes
using VNC a little simpler.  Also, enter your username.  Next, go to
the tunneling tab, select "Add...", then enter the following:

	Display Name: VNC
	Type: TCP
	Listen Port: 5901
	Check: Allow Local Connections Only
	Destination Host: localhost
	Destination Port: 5901

Then click "OK" in the "Add New Outgoing Tunnel" and "OK" on the
"Profiles" dialog box.  Sometimes the tunnel isn't added correctly, so
you might want to go back to "Edit Profiles" and make sure the
information you added is still there.

The equivalent command-line options for an OpenSSH client would be:

	ssh -L 5901:localhost:5901 ...

Then open a connection using the default profile, logging in with your
username and password.

When you are logged in, you'll only need to execute the following
commands one time:

	mkdir ~/.vnc
	touch ~/.vnc/xstartup

Then give the command (the first time this command is run, you will be
prompted to create a new password for VNC):

	vncserver -localhost -geometry 1152x900 -query localhost -once

Once the vncserver is running on one of the Math systems, it will
remain running until either you kill it (with something like
"vncserver -kill :1") or the system is restarted.

Next start the VNCViewer program on your PC and enter "localhost:1"
for the "Server".

You should get a new window with a login screen for the Sun system
here in Math (this might take a minute or two to show up).  Login on
that screen with your Math username and password.

You should now be set to run Maple and other software here.

When you are finished you can just close the VNCViewer and give the
command "logout" in the SSH window.  The next time you are ready to
work on your Math homework, you can just connect with SSH and the
VNCViewer, without having to start the vncserver and login.

The way all this works is:

VNCViewer(localhost:5901) <-> (localhost:5901)SSH(sunbelt:ssh) <-> 
(sunbelt:ssh)SSH(localhost:5901) <-> vncserver(localhost:5901)

The vncviewer on your PC talks to the SSH client on your PC over port
5901.  The SSH client talks to the SSH server using the SSH protocol.
The SSH server on sunbelt talks to the vncserver on sunbelt over port
5901.  When you start the vncserver it prints out a line like:

sunbelt.math.utah.edu:8

The number at the end of that is the "VNC display number", which maps
to the port number by adding 5900 (eg. display 8 would be port 5908).
The changes to the SSH tunnel to accomodate using display 8 would be,
to change the destination port in the tunnel to 5908.
