School of Computing Resources
Students enrolled in courses (CSCE, SOFT, and RAIK) taught by faculty of the School of Computing, (CSCE, SOFT or RAIK) automatically have accounts on the cse-linux-01.unl.edu server. To access this server, the easiest way is to open a terminal window in MacOS, or the Command Prompt or PowerShell in Windows 10 or 11, and use the ssh command:
ssh jdoe2@cse-linux-01.unl.edu
Substituting your MyRed login for jdoe2 in the command and entering your MyRed password when prompted. If you have never logged into the cse-linux-01.unl.edu server, a new home directory will be created for you. The cse-linux-01.unl.edu server offers a variety of software development tools, frameworks and services including MySQL server accounts. You can also access cse-linux-01.unl.edu using the NoMachine application if a GUI interface to the server is needed.
Some students may need a School of Computing (SoC) account (refered to as your CSE account) if they are doing research with faculty or accessing legacy software that is only available on the legacy CSE systems. This CSE account is used to access legacy SoC servers, websites, and network shares. A CSE account is separate from a My.UNL account (e.g. jdoe2) which is used to access UNL services like Canvas, Box, and Microsoft 365, and a TrueYou account (e.g. 12345678) which is used to access NU (system-wide) services like MyRED and Firefly. Usernames for CSE accounts do not contain any numbers, and the password for your CSE account is not synchronized to your My.UNL or TrueYou account password. If you have been told by an instructor or faculty member that you need to access the legacy systems using a CSE account, you can create one online at https://cse.unl.edu/claim by entering your full @huskers.unl.edu email address. After submitting your Huskers email address, you’ll receive a confirmation email at that address; click the link in the email to verify your identity and set up your new CSE account. This process will prompt you to choose your own password for your account, complete the consent form to agree to the university’s computer use guidelines, and then provide you with the username (or LoginID) for your CSE account. Make note of the username/LoginID for your CSE account, as it will be different than the My.UNL account username you use to access Canvas and other UNL services.
If you already have a CSE account (e.g. from a previous CSCE/SOFT/RAIK course) but don’t remember your username, go to https://cse.unl.edu/lost_login. If you have forgotten your password, go to https://cse.unl.edu/reset_password. Both links will prompt you to enter your full @huskers.unl.edu email address to have your CSE login sent to you or request your password be reset.
Below is a quick start guide on resources available for students enrolled in SoC courses.

How do I change my CSE password?
Your CSE login and password are synchronized across various School of Computing (SoC) hosted Windows, Linux, and Web services. Changing a synchronized password on one SoC system will change your password across all SoC systems.
We highly recommend you change your password on Windows or using the account management utility portal. The password synchronization works better from this side.
From the Web: Log in to the School of Computing Account Management Utility (AMU) (https://cse.unl.edu/account) with your CSE account credentials and then clicking on the change password link from the navigation links on the left.
From Windows: In order for you to change password, first login with your old password, then press Ctrl + Alt + Delete at the same time. You will be presented with a set of options, one of which will be to change your password. Click on "Change Password" then enter your old SoC password and your new password as requested by the system.
From Unix/Linux: To change the passwords on a Unix or Linux command line, open a terminal and login to your account. At the shell prompt enter the command "passwd". Enter your current CSE password and press enter, then enter your new CSE password when prompted.
Please take the time to select a good password. When you change your password, the system will reject any password that does not meet the following complexity requirement: A password much be at least seven characters long; a password must contain at least three of the following four character sets: lowercase, uppercase, numbers and punctuations; a password cannot contain your login or your first or last names as part of the password.
Where is my SoC (CSE) email forwarded to?
As of May 20, 2019, university policy requires that all university communications be forwarded to the student's @huskers.unl.edu email. As such, all email sent your School of Computing (SoC) account will be forwarded to your @huskers.unl.edu email. No action is required on your part to enable this forwarding. For more information on this policy or if you are a new students and need to claim your @huskers.unl.edu email, please visit https://its.unl.edu/helpcenter/student-email-migration/.
How do I change my Linux systems login shell?
Your School of Computing (SoC) systems login shell defines how the department Linux workstations and servers (CSE and CSCE) will behave when you login. The shell is the user's interface to the Linux operating system allowing program execution along with capabilities to create, edit, and examine files and directories on the server. Shells also incorporate the elements of programmability by providing control flow statement-commands. This statement-command syntactic format varies with different shells, and some programs are sensitive to the shell in which they are launched. The choice of login shell can also affect the behavior of client applications that establish SSH protocol connections to the SoC servers.
Changing your login shell can be done anytime by logging into the SoC Account Management Utility (AMU) and selecting your shell under the
Account Settings
menu.
Like your password, your choice of login shell is synchronized across all School of Computing Linux workstations and servers.
When does my School of Computing account expire?
For information on when your School of Computing (SoC) account expires, if you passwords are still valid or expired, and other SoC account related settings, visit the School of Computing Account Management Utility (AMU) page at https://cse.unl.edu/account.
I forgot my CSE password or login
If you have forgot your password, visit the School of Computing (SoC) Account Management Utility (AMU) page at https://cse.unl.edu/reset_password. Enter your email account, for students this would be your @huskers.unl.edu email. An email with a link to reset your password will be sent to your email.
To recover your CSE login id, visit the AMU login recovery page at https://cse.unl.edu/lost_login and enter your email. This will send an email to you containing your CSE systems login id.
Who should I contact for account related problems?
If you are unable to find a solution to your problem in this FAQ, your next step is to consult the School of Computing (SoC) Student Resource Center in Avery Hall (room 12). The Student Resource Center is generally open from 9 a.m. to 7 p.m. Monday–Friday. If the Student Resource Center is unable to address your problem, email support@cse.unl.edu. When you send an email to support@cse.unl.edu, please include your SoC login and provided as much detail as possible. When applicable, include the system you are using (a Windows system in the lab, the cse.unl.edu server, a Linux system in the lab, your personal laptop, etc.), the operating system on your personal device, the task you are trying to accomplish (date and time may help if you were using cse.unl.edu), the command you are running, any error messages returned, and any other information that would assist in focusing the diagnostics on your problem.
How do I check my disk quota?
If you are having issues saving file to your home directory (Unix) or your Z: Drive (Windows), you might have exceeded your disk quota.
Quotas are used to limit the amount of disk space used and the total number of files of each user. Disk space used is measured in blocks, where 1 block equals 1024 bytes(1KB).
There are two values (called limits) — a soft limit and a hard limit — for both the disk space used quota and the number of files quota. You can continue to increase your usage over the soft limit until you either reach the hard limit or the established time limit (usually a week). Once the hard limit has been reached, all further attempts at file creation will fail with an error message.
The simplest way to view your disk quota is to visit the School of Computing Account Management Utility (AMU) page at https://cse.unl.edu/account. After login, the AMU page shows various details about your account including your disk quota and usage.
To check your disk quota under Unix, use the command "quota -v" at the Unix command shell prompt.
