Using the SUN SPARCclassic Xterminals
This is divided into five parts. They are: Overview, DISPLAY environment, Operation, Menu and Exiting your session.
For more information, consult the SUN Xterminal Operation Manual in the lab.
Overview
The Sun Xterminals located in room B50c (the basement of the Beckman Center) need a host like pmgm.stanford.edu to boot from. They are known as disk-less workstations and have only a CPU and internal RAM.
They get the operating system and application processing power from pmgm.
There are nine Xterminals, each named after an ammino acid.
- Each can be identified through their full name or their abreviation.
For example, if you look on the bottom of the computer box, you will see:
- glu
- glutamte
- 171.65.20.16
- The first name glu is the nickname of the computer
- The next is the fully qualified host name
- The last is the IP (Internet Protocol) number
This is important to know. When you access another computer, you need to tell the remote machine where to send the output. This is know as setting the DISPLAY environment.
Setting the DISPLAY environment
When you start one of the xterminals, you make a connection between pmgm.stanford.edu and your Xterminal (in this case will use glutamate)
The two machines cooperate and pmgm sends the output (e.g. windows, including graphics and text) to the glutamate.
In all other cases, you need to tell the remote host that you logged into where to send the output. This is done via the DISPLAY environment. To set it, type:
- setenv DISPLAY glu:0.0 (Those are ZEROS!)
To check if the DISPLAY is set correctly, type:
- env | grep DISPLAY
You should see: DISPLAY=glu:0.0
NOTE: You may use the nickname, the long name or the IP address as the DISPLAY variable. setenv DISPLAY 171.65.20.16:0.0 works as well(and in some cases better if name resolution is not working) as the names.>p>
Operation
1. If you just powered on your Xterminal, you will see a window labeled:
- Login to pmgm.stanford.edu
You might have to type in pmgm if no machine is listed in the window
- Note: You must always login to pmgm! That is the only server that knows about your Xterminal.
2. Next, type your Bioinformatics Resource username and password. (HINT: This is your cmgm username)
3. The default terminal type is xterm
You will see a message "running openxt".
If openxt fails to run or if nothing happens, you can try running it by hand:
- Type: source /usr/lib/Login and source /usr/lib/Tcshrc
- Then type: openxt
Menus
The menus are accessed by using the RIGHT MOUSE BUTTON on the blue desktop.
Follow the pointers to the right for sub-menus. Below is a diagram of the menu system. Menus are listed in bold and applications are normal text.

Exiting your session
Caution: Merely closing the open windows does not end your session! You must:
Use the Workspace menu and choose Exit. Answer yse to the "really want to" prompt.
