1. X WINDOWS AND UNIX UNIX computers use a Graphical User Interface called X Windows. A UNIX computer can display its X Windows on your PC if you have an X Windows server program installed. Examples of X Windows server programs include PC-Xware or XWin-32. Be sure to start the X Windows server program on your PC before starting the X programs on the UNIX computer. In the examples below, the Genetics computer is assumed to be the the UNIX host for illustrative purposes. 2. TELNET AND XTERM You can start X Windows programs on the UNIX computer either by typing the commands from telnet, or by starting them from your X Server program on your PC. A safe way to start most X programs is to first open an xterm from the UNIX computer to your PC, then to start the X programs from the xterm window. The UNIX computer needs to know the IP address of your PC. 3. HOW CAN I FIND MY IP ADDRESS? From a telnet connection to a UNIX machine, type: who | grep username (substitute your own username) to display the IP address of your PC. The "|" (pipe symbol) sends the results of the who command into the grep command, which then searches for the pattern "username". 4. HOW CAN I TELL THE UNIX COMPUTER MY IP ADDRESS? From telnet, type setenv DISPLAY my.ip.address:0 Substitute your PC's IP address, and don't forget the :0 at the end. That sets an "environment variable" called "DISPLAY" to the value of your PC's IP address. If you always connect from a PC with the same IP address, you can put that line in your .login file. Test your X Windows setup by running the clock program, type: clock & 5. HOW CAN I START THE FILE MANAGER PROGRAM? From telnet, type filemgr & The name of the program is filemgr and the & tells it to run in the background (so that you can type other commands if you wish). Alternatively, double click on the filemgr icon in the PC-Xware Connections group. To set this up, use rexec with the command line /usr/openwin/bin/filemgr -display your.ip.address:0 & Click here to see the File Manager Window. 6. HOME DIRECTORY When filemgr starts, you are located in a folder on the hard disk called your home directory. Your home directory is /home/username (substitute your own username). 7.
