Unix: Introduction to Unix at Princeton and Frequently Asked Questions (FAQ).
Your Unix account is for use in classes that use Linux computing and programming facilities, and for publishing personal web pages to your Linux account. (The terms Unix and Linux at Princeton can be used interchangeably.) There are two clusters maintained by OIT for general use by the University. Each of these clusters consists of several machines that can be logged into, and Unix users often refer to "logging into arizona" or "logging into nobel." Nobel is intended for computationally intensive research computing, while the Arizonas are for reading email and designing webpages.
5GB of Central Storage Space
It is important to understand that each University netID is granted a Unix account, and that this is the same file space as your Central File Server home directory. This storage space on the Central File Server is often referred to as the H: drive, as students logging into the Princeton domain have their Central File Server directories automatically mapped to the H: drive. It is the same location as your Unix account; but can be seen through a graphical user interface.
Command Line Connection
If you want to connect to your Unix account via a command line interface, using a client such as Secure Shell, you will need to enable your Unix account first. Please see how to enable your Unix account with a shell to proceed.
- To see if your Unix account is enabled and to activate it for SSH purposes, visit the Enable Unix account Web page. Log in using your University netID and password.
- You should also check your current Central File Server (Unix /H: drive) home directory permissions to ensure that they are secure and that your files are not viewable by others. Log in to the Unix Security Settings Web page. Use your University netID and password.
What Servers are Available?
- Arizona (arizona.princeton.edu) is a Unix cluster that runs Red Hat Enterprise Linux 6. It is the most commonly used cluster, and most day-to-day users log into it. Arizona is made up of the two machines - yuma and phoenix.
- Nobel (nobel.princeton.edu) is two Linux servers Compton and Davisson PUIAS Linux version 6.2
It is sometimes necessary for a user to log into a specific machine rather than allowing the cluster to choose a location. Anyone can log into yuma.princeton.edu just as they would log into arizona.princeton.edu. For detailed technical specifications on these servers, as well as the licensed software on each cluster, please see Solution 9780.
Your Unix account by default contains a folder that is named public_html. This folder is already configured with the correct world readable permissions so that you can easily publish personal web pages. Just create your .htm or .html web pages using the editing software of your choice, and save the files to your public_html folder. The easiest method is to map a drive to your Files folder on the Central File Server for easy access. Full instructions can be found in at www.princeton.edu/files - click on the link for your operating system. Web publishing information can be found at www.princeton.edu/webpublishing.
Make sure your account is set up to be able to host a Web page. Steps for doing so are provided in Solution 3502.
The following links contain documentation written for individuals who are interested in learning about Unix computing at Princeton. Many University departments own and support Unix systems and often make these available to their staff and students. Those using departmental Unix systems will also need instructions from the department on connecting to and logging in to the computer.
