UCL Remote Login

Contents: [Secure Shell] [Virtual Network Computing] [File Transfer]

Secure Shell

The UCL supports access through secure shell (ssh). You just need point an ssh client at one of the machines in the cluster.

Windows
Windows does not come with an ssh client but there are many good one available for free. I like PuTTY. When you run PuTTY, make sure to check the SSH protocol box, as Telnet is the default.
Linux
Most Linux distributions now come with an ssh package. With this package installed, logging into the lab is as simple as typing a command such as: 
$ ssh zelle@molly.wartburg.edu
Macintosh
I'm not sure what the status of free SSH clients for the Mac is. I know there are some nice shareware products. You might check with Dr. Breutzmann.

Virtual Network Computing (VNC)

VNC is a thin-client protocol that allows for a remote graphical login giving you a remote working enviroment that is just like what you would get if you were actually sitting at one of the UCL machines.

In order to use VNC, you need to have a VNC client for your local machine. There are many different flavors of VNC. For Windows and Linux I recommend TightVNC. For the Mac, your best be is probably Chicken of the VNC.

The LCL is configured to allow direct login through a VNC client. You just have to point your VNC viewer at one of the machines. VNC session numbers are used to specify the screen size of the login. You can use reduced quality desktops on slower connections. The default session (:0) gets you 1024x768 full color; session :1 is 800x600 full color and session :2 is 640x480 256 colors. For example to get a 1024x768 full color desktop on neon, just point your VNC viewer to neon.wartburg.edu:0.

File Transfer

You can transfer files to and from the UCL machines using SSH with either an SCP or SFTP client. Most Linux distributions come standard with both SCP and SFTP as part of the standard SSH package. For Windows, a good, free client is WinSCP. For the Macintosh, there are a number of good shareware programs available. Consult with Dr. Breutzmann if you need help.
