Account FAQs

What is an ICS account?

Your ICS account is used to access ICS resources such as the ICS lab computers, ICS email, the ICS Wiki, and any ICS servers. Your ICS account is distinct and separate from your UCInetID.

Who can get an account?
  • Students (Undergrads & Grads): All ICS majors and students enrolled in most ICS courses are pre-authorized for an account.
  • If you are a non-ICS student/faculty working with an ICS professor, you may also qualify for an account.
  • Any staff or faculty members who are under Bren School of ICS.
What is an ICS Gsuite account?

All ICS faculty, staff, grad students, and sponsored visitor accounts have access to the ICS Google Account. Your username will be and a separate ICS Gsuite password, which may be different than your ICS password. The ICS Gsuite includes the following applications:

  • ICS Gmail
  • ICS Google Docs
  • ICS Google Sites
  • Unlimited storage
How do I get an ICS account?

I am enrolled in an ICS course, why can't I get an account?

Our system is linked to the UCI registrar's database, and we receive updates once a day. If your classes were dropped because you have not paid your fees, you will not be eligible for an account until your fees are paid. If you are adding a class, please wait overnight to ensure that we get the updated information.

Where do I go to log in?

Students taking ICS classes may access the ICS labs located on the 1st and 3rd floors of the Computer Science building. Check the Lab Information page for information on lab locations, operating hours, and hardware and software specifications. Note that these labs are not “public” labs in the sense that they are only for students taking ICS courses.

How do I access my account from off-campus?

Now that I have an ICS account, what are my responsibilities as a fellow user of a multiuser system?

All UCI and ICS students are expected to follow a system of ethical academic and computing policies designated by the University of California and the Donald Bren School of ICS. You will be required to read these policies as part of your account activation process, and you are responsible for knowing what is and is not acceptable behavior regarding your ICS account and the use of school equipment and facilities.

For details, please refer to the Computing Policy section.

How do I change my open file limit

You can determine your current open file limit with the command:

ulimit -n 

The default open file limit is set to 1024. Each running process uses a file descriptor and so each of your running processes will count against this limit.

Most research computing ulimits, including the open file limit, are assigned based on group membership. Ask your advisor to send a message to asking that you be assigned to a group that has higher open file limits.

The ulimits on general use computing, such as openlab, are adjusted on a case by case basis. An instructor or faculty member will need to make a request to

Heldpesk: On research computing, you can determine which group has increased open file limit by looking in /etc/security/limits.d/10-owner-limits.conf. If the file is absent, then a puppet change is required.
