For many of the computers on the network in the university, a user's NEXUS credentials provides mobility of users login credentials from one machine to another. This includes Engineering Computing labs and services such as engterm.
In addition to mobility of login, Engineering user's have access to remote storage, NEXUS file server (N drive), so that their files may be accessed from other machines they log in to. Users are encouraged to save to this remote drive when possible to prevent data loss from scheduled cleaning of a machine's local drive.
Information regarding NEXUS credentials, user ID and account creation, forgotten passwords, NEXUS file server (N drive), NEXUS profile server, remote file access, personal web pages, and profile resetting can be found below.
New students and employees should just be able to log in to Nexus PC workstations using their WatIAM user ID and password (same as used for the Quest student information system). If you need to change your password, do it via the User Access link on the WatIAM web page.
Nexus accounts are created automatically when your informaiton is entered into the WatIAM identity management system. This process is controlled by the Registrar's Office, Grad Studies Office, Human Resources, etc. Once you are able to log in to the WatIAM web page, you should also be able to log in to a PC in the Nexus domain.
Email accounts are also provided. Undergraduate students get an email account on portal.office.com. Graduate students, faculty and staff get email accounts on the Microsoft Exchange server, connect.uwaterloo.ca. Incoming grad students get this account automatically, while it must be requested for new faculty and staff.
Some unpaid visiting scholars will need guest accounts to be created manually. Please see your own academic department's computer technician to get your account.
Your Nexus password can be changed at the WatIAM site. Otherwise, for security reasons, you must visit the Information Systems and Technology Help Desk (Math and Computing -1052) in person, with photo ID to have a password changed.
Please try to choose a password you can remember. uWaterloo requires you to use upper and lower case characters as well as some numbers and non-alphabetic characters to make it difficult to guess.
In Engineering, your personal data files are stored on a faculty file server called ecfile1, which is mounted as drive N on your Nexus account. There is a disk quota (currently 2 GB per user) on ecfile1. If you reach this quota limit you will be prevented from writing to the N drive, resulting in possible data loss. Please do not store files on the computer desktop. These will end up in your profile space (see below), not on your N drive. Files stored on the desktop may be lost, if the log-off process is interrupted for some reason and are not stored in a safe place until you log off. It is much better to store your files directly on your N drive.
Courses and projects using particular software sometimes require increased storage space for large data files. The quota is not generally increased on an individual basis. Instructors should arrange to have their class's quotas temporarily increased in this situation, by notifying the Eng. IT Service Desk.
Files stored on ecfile1, the faculty file server(N:), are backed up daily, but backups are not user-accessible. If you need files restored from scheduled backups, please inquire at the IT Service Desk (Engineering 2, 1308A).
On campus, or remotely through a VPN connection, it is possible to map your Nexus N drive space on ecfile1 via the followin network location: \\ecfile1.uwaterloo.ca\your_userID. On a Mac or Linux computer, use forward slashes instead of backslashes. Authenticate as nexus\your_userID if you computer is not joined to the Nexus domain.
What is my Nexus profile ?
Your Nexus profile is where your Nexus desktop and other Nexus customizations are stored. It is stored on a separate server from your home directory (N drive), with a separate (smaller) disk quota of 110 MB. Your data files should not be stored on the desktop. There may not be enough space to properly store data files. If the log-out process should have an error, you will lose your files, since they will not be permanently stored on our server. They will remain on the C drive of the workstation you were last on, but only until the nightly clean-up process runs to clean private files from the workstation.
Why is my Nexus profile over quota ?
Some applications programs store information in the profile. There may be cases where some users need additional profile space. However, in most cases it is caused when users store files on their Desktop. This causes poor login performance because the entire profile is copied to the local hard disk upon every login. Also, any files stored on the desktop are vulnerable to permanent loss until you've logged off successfully.
If you have stored files on your Desktop, remove them and store them on your home directory. To access your profile from Nexus, map a drive letter to the following network path:
Move the files from the Desktop folder to a folder on your N drive. You must also remove them from the desktop on your workstation by deleting them, or they will be stored in your profile again.
The www.eng server provides general purpose web space for students, clubs and course web pages. You get a home page on the web on Engineering's Web server, www.eng.uwaterloo.ca, when you create your Waterloo Nexus account. Just place your Web pages in N:\public_html\ folder on your N drive. If the public_html folder does not exist in the root of your N drive, create one with that exact name. To see how to access your N drive from non-Nexus machines, see remote file access above. Your publicly accessible Web address (URL) is: http://www.eng.uwaterloo.ca/~your_userid.
Editing Web Pages: To edit your web pages you can use the NVU HTML editor (or any of the word processors) to edit your default Web page. Your default home page must be called
index.php. Access to subdirectories of public_html is permitted by default (for example http://www.eng.uwaterloo.ca/~your_userid/folder_name/).
Setting Up Scripts: You can run Common Gateway Interface (CGI) scripts on your Web account. These may be written in Perl or any other language. Place your script in a directory called "cgi-bin". Make sure your script works by running it by itself (on sftp.eng.uwaterloo.ca), and make sure it has public read and execute permissions. From your Web page access your script with the following URL: http://www.eng.uwaterloo.ca/cgi-bin/cgiwrap/your_userid/your_script_name. This makes the script run as your user ID. PHP is also available on www.eng for server-side scripting purposes.
Your Waterloo Nexus account stores user modifications to Windows on a special profile server (ecfile2). Most account problems occur when the user profile becomes corrupted, perhaps because you've run out of your allotted space on the server. If you need assistance, please go to the IT Service Desk (E2-1782B) to have your account fixed.
If you are having trouble logging in to your Nexus account, you can try resetting your Nexus profile by going to the Nexus profile reset page. Do not use this reset script while logged in to a Nexus workstation. After the profile reset, log in to a workstation that you have not logged into that day. If the problem remains, please go to the IT Service Desk (E2-1782B) to have your account fixed.
