EDORAS provides Linux shell accounts with access to various software applications, Apache web server, compilers, and databases. Faculty may obtain EDORAS accounts for themselves and their students. EDORAS has replaced ROHAN for instructional support accounts.

Class Accounts

Class Accounts are requested by faculty and are normally available only for the semester issued. They have the form of aascnnnn, ie: cssc0123. The account sponsor may issue new passwords for a sponsored account and can access the files in a sponsored account, using the sg and usrpass commands. Class accounts expire on May 30 for the spring semester, December 30 for the fall semester, and August 30 for the summer semester.

Faculty may request class accounts by emailing [email protected] with the following:

  • Size if more than 200MB needed per account

EDORAS, the Academic Computing Server at San Diego State University, is administered by Information and Digital Technologies staff in the Library. The mission of EDORAS is to enhance the instructional mission at San Diego State University by providing to the Faculty, and Students academic computing resources for classwork and research.

The EDORAS name is taken from the capital city of Rohan from J. R. R. Tolkien's Middle Earth saga "Lord of the Rings". Rohan's inhabitants were a nomadic and highly skilled equestrian people.

All that is gold does not glitter,
Not all those that wander are lost.

--- J. R. R. Tolkien ---
