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.

Connecting to cse.unl.edu and other Unix servers with SSH from Windows
You can connect to the School of Computing (SoC) CSE server (cse.unl.edu) and other UNIX servers in the department using the PuTTY SSH client.
PuTTY can be downloaded from the this web site. After you have downloaded and installed PuTTY, you can use it to connect to cse.unl.edu.
Double click the PuTTY icon on the desktop or enter "putty" in the search bar to start PuTTY:
Enter "cse.unl.edu" in the Host Name (or IP address) field and hit enter.
The first time you connect to a remote host, you will receive a message stating: "The server's host key is not cached int the registry. You have to guarantee that the server is the computer you think it is." You should click "Yes" here.
Next, you will be prompted to enter a user name and password. This is your SoC user name and password; this example uses "sac" as the user name and cse.unl.edu as the login server:
If you are prompted for a Verification code: after entering your password, examine the user name you supplied. User names that end digits (1 through 9) are not SoC user names that can be used to login to CSE and other SoC servers.
How do I print from a Windows PC on campus?
New! Printing has changed, please use the updated instructions below.
To print documents from computer lab Windows PCs or your personal Windows PC laptop you will need to install a network printer.
Launch File Explorer. Go to search in task bar and search "File Explorer" or select the File Explorer from the Windows System menu.
In the File Explorer address bar, type in \\its-acadprt-unl.unl.edu as shown.
When you are asked to enter your network credentials, you will need to login with your MyUNL credentials. Your user name must be provided as MyUNL_ID@unl.edu where MyUNL_ID is your UNL login ID.
The Remember my credentials box must be checked for printing to work properly.
Once successfully authenticated, you will be presented with a list of printers. Printers are generally named by the building and room they are in. Now click on the printer you want to connect to and select connect.
NOTE: Only the below printers are available for students:

Common Issues
On your personal device, make sure you are connected to eduroam and eduroam must be configured as a private network.
Norton Anti-virus and certain other anti-virus vendors will prevent outgoing SMB connections. Please use the UNL provided anti-virus software CortexXDR offered thru UNL ITS.
If Windows does not prompt you for credentials, or if you cannot browse the \\its-acadprt-unl.unl.edu network, the problem lies in the Windows configuration. Verify eduroam is a private (local) network, verify your system is fully updated to the latest Windows updates and then verify that the SMB client is enabled. Here are some Instructions for how to determine if your SMB Client is enabled, and how to enable it.
There are many caveats to windows printing. If you need help please email support@cse.unl.edu. You may be asked to bring your personal device (laptop) in to the support office if your problem cannot be resolved via email.
