DO NOT turn off, or power-cycle, the machine. Besides being against lab policy, you will cause serious problems for anyone that was remotely connected to the computer. If your machine is locked up, you can try pressing ctrl-shift-break, which will kill the current login session and hopefully unfreeze the machine. Another option: Log in remotely from another computer using ssh and run

kill -1 -1

Be warned, however, that either method will probably result losing any unsaved work! If both methods fail you, contact the ECEn SysOps.

Refer to the Disk usage FAQ.

Your first line of support for individual software packages (especially in cases where you are able to run the program but it is not behaving as expected ) is your class TA. If the TA determines that the problem has to do with the system or installation, he or she can then contact the SysOps to address the situation. Sysops are generally unable to help much with questions about the practical use of the installed tools.

If you have an email account through the ECEn dept., your email address is your user name followed by "@ee.byu.edu" or another reasonable user name you chose. Note that undergraduate students do not receive an ECEn email account by default. (You may come to CB 409 to request one). You do receive a CAEDM email account automatically. For example, if your CAEDM username is "fluffy", your CAEDM email address is "fluffy@et.byu.edu".

If you have more questions about email please check out our email FAQ and CAEDM's Email Information.

CAEDM's Knowledge Base contains some info on UNIX basics. Typing man in an xterm followed by a command you want to learn about provides access to UNIX online manual pages, an excellent source of information. There are also many excellent guides and tutorials on the internet, such as this UNIX Tutorial for Beginners.

On the login screen, click "Sessions" . Choose your preferred window manager/desktop environment, then log in normally.

Check out the "X window manager" Wikipedia article and the excellent catalog of window managers available at xwinman.org .

Yes. On the HP-UX computers, the java compiler and other java related programs are in /opt/java1.5/bin . On the GNU/Linux machines, they can be found in /usr/java/j2sdk1.4.1_05/bin .

There are two basic categories of Spice machine: those that run HP-UX, and those that run GNU/Linux. The HP-UX machines all have large gray cases with a small built-in LCD. The other Spice machines are running GNU/Linux. It's important to know that although they are very similar, HP-UX and GNU/Linux are two different operating systems. What works on one will not necessarily work on the other.

Yes, using SSH, however the method you use will depend on whether the machine you're trying to connect from is on-campus or not. If you are making a connection from a BYU computer, all you need to do is make an SSH connection using your CAEDM username and password. For example, if my username was "aladdin" and I wanted to connect to the spice machine "sesame", I would type the following in an xterm prompt:

ssh -l aladdin sesame

If you get a message saying that the authenticity of the host can't be established, type "yes" to continue.

If you want to connect to a Spice machine from off campus, you will need to make an SSH connection to salt.ee.byu.edu using your CAEDM username and password. From there, you can access to your CAEDM home space and make SSH connections to other Spice machines.
