Shell Access

Computer Science students have access to an open computer lab that has 16 computers and a Unix server. Students also have shell access that allows them connect via remote access so they can program from home at any hour.

Access

You can login to our Unix server machine remotely using ssh. This provides a terminal (text based) interface to our linux server.

Use ssh like this:

you@yourhost$ ssh your_username@elec.tricity.wsu.edu

Windows users, download PuTTY ssh here. Save it to your desktop. When you run it, type elec.tricity.wsu.edu into the box labeled Host Name, then select the SSH dot under Protocol. go back to Session and type in CSLAB in the Stored Sessions window and press Save. Now double-click on CSLAB to connect. The PuTTy homepage is http://www.chiark.greenend.org.uk/~sgtatham/putty/.

File Transfer

scp [secure copy] is the preferred way of transferring files back and forth. Unix scp should come with ssh, and a graphical version of scp for Windows is available at WinSCP. You might also take a look at the WinSCP homepage.

Use unix scp like this:
you@yourhost$ scp your_username@elec.tricity.wsu.edu:remotefile localfile
you@yourhost$ scp localfile your_username@elec.tricity.wsu.edu:remotefile

If you use a “.” in place of the filename in the second argument, a copy will be made in the current directory with the same file name as the original. (That is, it works the same way as rcp or cp).

People who have linux at home can also access their files graphically through Konqueror (the KDE browser). You will need to ssh to elec.tricity.wsu.edu first, and accept the host key. Use the following URL:
sftp://your_username@elec.tricity.wsu.edu/

If you have problems, comments or suggestions, email the System Remote Access Coordinator at tchelp@tricity.wsu.edu.

Frequently Asked Questions

How do I get my Floppy/CD-ROM to work?

First make a device link on your desktop, if one doesn’t exist already. Right click > Create New > Floppy (or CD/DVD-ROM) Device. Then set the Device (3 rd tab) to /dev/cdrom for a CD and /dev/fd0 for a floppy.

Second, “mount” the device by right clicking on it, and selecting “mount”. Make sure to unmount the device before removing it, or you may lose files, and people will not be able to use the floppy or CD-ROM. (Linux tries to use the floppy while it isn’t there. Obviously this is not good).

If someone else has forgotten to unmount their floppy on your computer, you probably will get a “permission denied” problem when you try to use it. The easiest solution is to reboot the computer. If you don’t want to restart the machine, contact the computer Help Desk at 372-7334 or tchelp@tricity.wsu.edu for assistance.

How do I get access to campus e-mail?

WSU Tri-Cities email accounts are (currently) separate from Computer Science Accounts. You’ll need to get one. Tick the “WSUTC Mail Account” on your account form when you turn it in. Pick up your information from Admissions upstairs near the entrance to the West Building. If you forgot to do the form, or you have forgotten your email password, contact the computer Help Desk at 372-7334 or tchelp@tricity.wsu.edu for assistance.

There is web-mail at webmail.tricity.wsu.edu, and a native Linux client KMail. If you want to setup an email program, the IMAP server is mail.tricity.wsu.edu, and the SMTP server is also mail.tricity.wsu.edu. You can also login to mail.tricity.wsu.edu if you want to use something like pine or mutt.

I forgot my password. What do I do now?

Login to elec.tricity.wsu.edu using secure shell. SFTP is also available for transferring files. If you’re using a machine which doesn’t have native secure shell support (Windows, Macintosh), see our connecting guide for software and instructions.

How can I program or use these computers from home?

Login to elec.tricity.wsu.edu using secure shell. SFTP is also available for transferring files. If you’re using a machine which doesn’t have native secure shell support (Windows, Macintosh).

How do I create a gzip-ed "tar" archive?

tar –create –gzip –file homework-n.tgz

tar -czf homework-n.tgz

The KDE “Ark” program works as well, but it can be buggy.
