Computer Lab and Accounts

Each student in the course will have an account to use for coursework. If you are an engineering major, you will use your OCE account (OCE account names are usually something like your first initial and your last name). If you are not an engineering student, a cs100 account will be provided for you. If you don't know what account names you have, you can use the Account Lookup Tool to find out. If you are enrolled in the course, and there is not a cs100 account listed there for you, use your OCE account.

In any case, when you log in, you should run the command prep cs100f to initialize your environment appropriately.

These accounts are hosted on the machine ieng6.ucsd.edu, a load-balanced multiprocessor server running the Red Hat Enterprise Linux operating system. We will use the JDK 1.6 (also known as "Java 2 Standard Edition JDK Version 6") environment for Java programming. These resources are for work related to CSE 100 only.

Access to the server is available via workstations in the instructional labs in the basement of the CSE building, EBU3B, as well as the server, remotely using ssh. (Note: Tutors specifically for CSE 100 are planning to hold hours in lab B240.)

Getting into the labs

Labs are unlocked M-F 7am-10pm and Sat and Sun 7am-7pm. You can get in the lab 24 hours a day 7 days a week using the combination provided for this class. This combination is available using ACS's account lookup tool at http://sdacs.ucsd.edu/~icc/.

Getting logged on

Move the mouse. The screen should wake up. These workstations are dual boot Windows and Linux machines. If the machine offers you a Windows login, reboot into Linux:
- At the Windows login hit "Ctrl-Alt-Del", select Options, Restart, Click OK
- As the machine restarts, you will get a screen where you can choose to boot into Windows or Red Hat Linux. Use the keyboard arrow keys to choose Linux and hit enter.
Now you should have the Red Hat Enterprise Linux screen, and a box asking for your username (or login). Type your username (followed by Enter, of course). Don't know your login or password? Get access to a web browser and use the ACS account lookup tool!
When prompted, type in your password.
You will be logged in and brought to a Linux desktop environment. Towards the left of the top menu bar is the Applications menu. Clicking it will pull down a menu with various options.
You can customize the graphical user environment provided for Linux if you want. (For example, any of the icons in the pulldown menus can be dragged to the menu bar to make accessing them quicker.) But for the basic command line interface, just right click on the background and select "Open Terminal" from the menu shown. You can do this multiple times to get multiple Terminal Windows. (When you log in remotely, you will be automatically in a terminal window).

Getting logged off

Don't forget to log off of your machine when you are leaving it! In the GUI, click on the red hat in the lower left hand corner and select Log Off. Then Click OK in the dialog box that pops up to complete your logout.

You can use your home computer or any other system to experiment with programs for this course. However, your programming assignments will be graded using the 1.6 javac compiler for Java, on ieng6 only. It is your responsibility to make sure your programming assignment solution works in this environment!
