How do I change my CSE password?

Your CSE login and password are synchronized across various departmental Windows, Linux, and Web services. changing a synchronized password on one system will change your password across all departmental systems.

We highly recommend you change your password on Windows. The password synchronization works better from this side.

For Windows: In order for you to change password, 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 password and new password as requested by the system.

For 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 old password and select new password.

From the Web: You can also change your password by logging in to the CSE Account Management Utility (AMU) page at https://cse.unl.edu/account with your CSE account credentials and then clicking on the change password link on this page.

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.

Prerequisites for hosting web content on your cse account.

CSE users can host web content such as HTML or PHP pages on the cse.unl.edu server. There are a few prerequisites such as required directories and permissions on these directories. This section will go over these.

Before we get started, a word on directory permissions. We'll need to grant others execute permissions on certain directories. Granting execute permission on a directory, allows others to access(traverse/come into) your directory, in this case the web server will need to access the HTML files you wish to publish. Note: This is not the same as granting read access on a directory, read access allows someone to list the content of the directory. When execute but not read access is granted, the user can only access files they know the full path to, and in addition they must have read access to the particular file in question.

  1. You will need to open a Unix command line session to cse.unl.edu. Since the steps are different for Windows and Mac users, this topic is covered in the respective FAQ sections.
  2. Make sure your home directory has execute permission for everyone(others). Note: the "~" symbol is a shortcut to "My Homedirectory". Enter "chmod o+x ~" in the command prompt as shown below.
     > chmod o+x ~ 
  3. Create a public_html directory in your home directory by issuing the command below. The public_html directory is the root of your Web documents. A world readable file placed in this directory will be accessible on the web by using the URL http://cse.unl.edu/~login_id/file where you would replace ~login_id with "~"+ your login id.
     > mkdir ~/public_html
  4. The public_html directory must also have execute permission for everyone(others). Enter the command shown below.
     > chmod o+x ~/public_html 
  5. You can now setup a index.html page (This is the default page serviced by the web server) to test your web site.

Where is my CSE email forwarded to?

All new CSE accounts created for students since August of 2011 are configured to automatically forward email to the Preferred Email Address on file in MyRED so that students only have to update their personal email address in one place. Your Preferred Email Address from MyRED is also used by Blackboard and several other systems on campus, so it is imperative that this is kept current. You can see where your CSE email is being sent by logging in to the CSE Account Management Utility (AMU) page at http://cse.unl.edu/account with your CSE account credentials and then clicking on the Account Settings link from the navigation on the left side of the page.

How can I change my CSE forwarding address (students)

To change the destination (delivery address) for your CSE email alias, log in to MyRED and update your Personal Email Address and make sure that this address is marked as Preferred. Your updated email address from MyRED will propagate to CSE the next time we pull a student enrollment report from MyRED, which is done weekly. To have your email address updated sooner, send an email message to support@cse.unl.edu after you have changed your email address in MyRED, and we can manually pull a student enrollment report from MyRED to update your delivery address.

Please Note:
  • Students are discouraged from publishing their CSE email address, as CSE accounts expire and are eventually deleted after a student is no longer enrolled in CSCE courses. For a permanent email address that students can continue to use even after graduating, visit huskers.unl.edu, and consider setting this as your Preferred Email Address in MyRED to have your CSE email (as well as Blackboard messages and other correspondence from the university) sent to your Huskers email address.
  • Do not populate the Work Email Address field or mark the Work Email as your Preferred Email Address in MyRED, as this field is overwritten for any students who are employed by the University of Nebraska (e.g. as a student worker or graduate assistant).
  • Do not list your CSE email address in MyRED, as this can create mail loops that will prevent messages from being delivered to you.
  • If your CSE account was created prior to August of 2011, you can log in to the CSE Account Management Utility (AMU) page at http://cse.unl.edu/account with your CSE account credentials and enable forwarding to your Preferred Email Address from MyRED from the Account Settings page. Note that you can not unforward your CSE email once forwarding to your Preferred Email Address has been enabled; you can only change the destination address.

Setting up a VPN connection to campus

Some websites and servers are secured by a firewall that only allows connections from on campus. To access these restricted resources from off campus, you will need a VPN connection. Most students don't have access to systems that aren't available from off campus, so a VPN connection is rarely ever needed by students.

Information Technology Services now operates a VPN service for faculty, staff and students. More information about their service is available at http://its.unl.edu/services/vpn.

For information on the alternate departmental VPN services available to faculty and staff, please refer to the sections on Setting up a VPN client under the Windows and Macintosh sections of the FAQ.

Visitor Registration for University Wireless Network

Visitors wishing to utilize the university's wireless network must register their device prior to connecting to the network. A device could be a laptop computer, tablet, smart phone, or anything else with a wireless network card.  There is no limit to the number of devices that can be registered, and there is no charge for wireless network access.

Visitor registrations are valid for 90 days. If you have registered as a visitor before and the system will not let you register again, please contact the Information Services Computer Help Center toll-free at (866) 472-3970.

Faculty, staff, and students should not register devices as a visitor, as registrations will be dropped for devices found to belong to university personnel.  Further, once a visitor registration expires, it cannot be re-registered. University personnel should log in to the registration page with their My.UNL (Blackboard) credentials to register their devices.

Register a Device Before Coming to Campus

Individuals planning to visit the university can register a new device by going to http://wifi.unl.edu and clicking the link under the "Visitor registration" heading.  We encourage visitors to do this prior to their arrival because devices will not have any network access until registered.

The registration process will ask for the computer's MAC/Hardware Address. Make sure to enter the address for the computer's wireless card (usually labeled as the Physical Address under "Wireless LAN Adapter Network Connection") and not the "Ethernet Adapter". Individuals who are not sure how to find the physical address for their computer's wireless card can contact the Information Services Computer Help Center toll-free at (866) 472-3970.

Registering a Device While on Campus

If a visitor has not registered their device before arriving on campus, he/she can connect to the "UNL-Wireless-Registration" SSID (wireless network) from their device.  Once connected to "UNL-Wireless-Registration", open a web browser (Firefox, Safari, Chrome, Internet Explorer, etc.) and you should be redirected to the Wireless Registration page. 

Click the Accept button at the bottom of the Connect page, then click the link under the "Visitor registration" heading.  From the Registration Menu page, click the red "Register a card" link and enter your personal information.  When asked for a "Hardware address", click the "Find my current MAC address" button, and then click the "Next" button once your MAC address appears in the text box. 

Connecting to the Wireless Network

After you have completed the registration process, wait 10 minutes, disconnect from the "UNL-Wireless-Registration" and then connect to either "UNL-AIR" or "UNL-AIR-E".  UNL-AIR is a public network that is not encrypted, and is the easiest to connect to after a device has been registered.  UNL-AIR-E requires the following shared credentials to encrypt network traffic:

  • Username:  unlwireless
  • Password:  encrypted

To connect to UNL-AIR-E without entering the shared credentials and configuring a security certificate, connect to UNL-AIR first and then go to http://its.unl.edu/huskertech/secure-it and follow the instructions to be migrated automatically from UNL-AIR to UNL-AIR-E.

UNL-Guest Network for Short Term Guests

A new alternative to registering the MAC address for wireless devices is to use the dedicated "UNL-Guest" SSID instead of connecting to "UNL-AIR" or "UNL-AIR-E". Campus visitors can select the "UNL-Guest" network SSID and input their name, email address, and mobile phone number. An access code is then sent instantly via text message (SMS) and email to the mobile device to grant the individual access to the network. Each access credential expires after seven days. Visitors may re-register to extend their access. The UNL-Guest network allows outbound access to public internet sites, while limiting access to UNL domains.

eduroam (Education Roaming) Network for Visitors from Participating Educational Institutions

Visitors from other participating educational institutions can access the university's wireless network by connecting to the "eduroam" SSID (instead of connecting to "UNL-AIR", "UNL-AIR-E", or "UNL-Guest") and signing in with their institution's single sign on credentials.
