Getting Help

system help

If you have any system-related problem with the CS machines, you can contact either the department’s system administrator:

Jeff Knerr
Room: 238A
Email: knerr at

or find one of the student system administrators:

You can also email sysadmins at This is a special mail alias read by all the sysadmins and some Professors. Sending questions to sysadmins will normally get a quicker response than sending something directly to a specific sysadmin.

Also, if you are getting error messages and want us to try to figure out why, please send a copy of the exact error messages (if you can), along with the specific commands you tried. If we are able to reproduce the error messages on our own, we will have a much better chance of figuring out what is wrong.

class help

Some of our classes, like CS21, CS31, and CS35, have ninjas/student mentors. They usually hold one or two study sessions each week. If you’re having trouble with your homework assignments, check our cs ninjas page for the study session times.

Obviously, see the Professors for any class-related questions.
