Personal Account
A UNIX account is automatically issued to you by the Computer Systems Lab (CSL) after you register for the course. This account includes and email account that is completely separate from the email account supplied to you by DoIT.
Locations & Hours
The computer labs for use by CS354 students are located on the first floor of the Computer Sciences building during the hours from 7 AM - 1 AM every day. You may also remotely log into these machines. To access the machines remotely, use the form: machineNameNN.cs.wisc.edu where the machine name is taken from the table below and NN is a 2 digit number as in the example: tux13.cs.wisc.edu.
See the Using SSH page for more information about remote access and Computer Systems Lab Instructional Facilities page for more information about the computer labs.
Note the simulator will only run on the netra cluster computers.
Sixteen machines are part of a netra cluster, and they are named n01.cs.wisc.edu to
n16.cs.wisc.edu. From a lab computer you can log into one of the netra machines
using the ssh command such as in this example: ssh n03.cs.wisc.edu.
Potentially every other student in CS354 could be currently using the same netra computer,
so you'll want to check how many are actually using the machine you've remotely logged into.
If there are more than 10 students logged into a machine, it is recommended that you log out
of it and try a different netra computer. Use the UNIX command who to display
a list of who is currently logged into a machine.

CS Computer Lab Accounts
A computer account is automatically issued to you by the Computer Systems Lab (CSL) after you register for the course. This account provides you with access to the lab computers, a disk quota (for file storage), and paper quota (for printing). Only registered students are given an account. To use this account you may need to activate it:- If you had a CS or Stat course in the previous semester your account still exists and is accessed using the same login name and password. If your prior account was for the Windows machines, you may not have access to those machines this semester.
- If you are a new user of the CS lab computers you will need to activate your account by following the instructions posted in each lab.
If you have probelms with your password or account go to the Computer Systems Lab (CSL), room 2350 CS, during regular business hours (Monday through Friday from 8 AM - noon, 1 PM - 5 PM). Make sure to bring your UW student id.
If you add after classes begin, there may be a delay until you are able to activate your account. Accounts are available the morning after the Computer Systems Lab receives notification from the registrar.
Your account will be deactivated if you drop the class unless you are taking another CS or Stat course.
New to UNIX?
If you are new to the UNIX operating system, you should attend one of the several scheduled UNIX Orientation Sessions that are offered during the first two weeks of class. Look at the CS1000 handout prior to attending the session. See the additional information is available to help you with UNIX:Printing
Basic instructions for printing from the instructional machines: In order to print from any of the computers your paper quota must be greater than 0. At the beginning of the semester all CS540 students receive an initial paper quota established by the CSL. If you exhaust your paper quota you must go to the CSL in 2350 CS during workday hours to purchase more pages.
All the instructional machines are set up to print to the printers in 1359 CS.
Each of your print jobs will be scheduled individually and may print out on any of the printers in 1359 CS. To check which printer your job is coming out on look for your login name on the monitor by each printer.
If there is a problem with one of the printers or there is no paper left in the print room first tell a consultant on duty in the CS302 computer lab, 1370 CS. If there are no consultants then send email to lab@cs.wisc.edu. Do not try to fix any of the printers yourself.
For further information about printing (how to check your quota, how to remove a job that you printed accidentally, etc.) check the printing section of the CSL documentation.
