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 (AMU) page at 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. You will need to open a Unix command line session to cse.unl.edu.
Since the steps are different for and users, this topic is covered in the respective FAQ sections. 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. Launch File Explorer.
If running Windows 8, from the Metro tiles screen, type 'File Explorer' and click on the resulting application. If you are running Window 8.1, File Explorer should be on the Start Menu.

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 Canvas 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 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 Canvas 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 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.
