Unix Timesharing


We provide a Unix system for use by the University community. This system is available to all users with a valid University Computing Account. The most popular uses are programming, personal Web site hosting, and statistical software.

Many schools at the University of Pittsburgh use the UNIX Timesharing Service for research, classroom work, and teaching. It can be used to run specialty software applications for engineering and mathematics that require a UNIX environment. It can also be used to access your disk space on the Andrew File System (AFS).

Individual students, faculty, and staff must connect to the UNIX Timesharing Service using their University Computing Account username and password. You can use space on the UNIX Timesharing Service to create a personal Web page. The Unix Timesharing Service has a quota of 5 MB.

You must connect to the UNIX Timesharing Service using SSH (secure shell) and SFTP (secure file transfer protocol). SSH enables you to securely log in to a remote computer and SFTP allows you to transfer files securely between two computers. If you use Web authoring software, you must publish files using SFTP.

Acessing the Andrew File System(AFS)

The University offers a distributed network file storage system known as AFS (Andrew File System) that enables you to store files and documents on remote AFS servers and access those files as easily as if they were stored locally on your computer. This file storage system was specifically designed for Unix users.  Every student, faculty, and staff member with an active University Computing Account has access to the University of Pittsburgh's AFS space.

Access the University of Pittsburgh's AFS cell "pitt.edu" by logging into UNIX Timesharing (please refer to our Unix Timesharing page) or by using an AFS client from www.openafs.com on your personal system. When accessing the University of Pittsburgh's AFS cell using an AFS client on your own computer, Kerberos 5 authentication is needed to upload or modify files. For information on Kerberos 5 authentication, please refer to our Kerberos page.

Files or documents stored on the AFS file storage system remain on the system after the owner is no longer affiliated with the University unless the user deletes the files. Authorization for the purging, permanent removal, and/or deletion of files or documents owned by users no longer affiliated with the University applies based on specific criteria that is approved by the CIO.
