AFS

AFS stands for Andrew Book System. It is a broadcast filesystem like NFS. In the summer of 1992, all user accounts on Athena were moved from NFS to AFS. Abounding NFS commands additionally appointment on AFS; however, there are abounding important differences amid AFS and NFS. You may also apprehension new subdirectories in your home directory: OldFiles, Public, Private, and www.

In NFS and UFS, you can set permissions on a file-by-file basis. In AFS, book permissions are defined for anniversary directory, and apply to the agenda and to all the files that agenda contains. They do not administrate to the subdirectories of a directory, aback the subdirectories accept their own permissions; however, any anew created subdirectory will accede the permissions of its ancestor directory.

Athena (OLH definition)

In May 1983, MIT appear the enactment of a five-year program to analyze new, avant-garde uses of accretion in the MIT curriculum. The MIT adroitness was anxious that too little was being done to accommodate the new computational technology into the undergraduate educational experience. Activity Athena, as the program was called, arose from this concern.

Project Athena’s authorization was to analyze assorted uses of com-puting and to body the abject of ability bare for a best appellation strategic decision about how computers fit into the MIT curriculum. In January of 1988, Activity Athena was accepted a three-year addendum to the original five-year program, and on June 30, 1991, Activity Athena came to an end. But the bake-apple of Activity Athena — the Athena system itself — was adopted as MIT’s bookish accretion infrastructure, with affairs to extend it above the educational sphere, into the research and authoritative activities of the Institute.

What, then, is Athena? It is a campus-wide networked computer systemserving the needs of MIT’s bookish community. Rather than having a distinct accretion center, Athena has over 600 end-user workstations broadcast about campus in both general-use and departmental “clusters” area acceptance and adroitness can go 24 hours a day, 365 canicule a year to do classwork, address papers, do claimed work, and acquaint with added computer users worldwide.

The Athena arrangement is absolutely composed of a ample cardinal of machines (workstations, printers, and servers) that are net-worked together, and is far added able than added accretion facilities you accept apparently used.

Athena provides a arch amid the two accustomed extremes ofstand-alone claimed computers and timesharing machines. Anniversary user of an Athena workstation has a dedicated, able multi-tasking computer at his or her disposal. And anniversary Athena workstation is connected to MITnet, the campus-wide computer network, so you can access a cardinal of aggregate casework that would commonly be available only on a axial facility.

Classrooms

Academic Accretion manages four cyberbanking classrooms which are available for use by MIT courses. Anniversary classroom has a cardinal of individual workstations, one of which is affiliated to a projection facility.In accession to these rooms, there are a cardinal of lecture halls that are able with an Athena workstation for the instructor connected to a bump system. There are no workstations at the students’ seats.

Clusters

As of 1999, there are 17 general-use Athena clusters on campus, as well as a cardinal of clandestine authoritative clusters. The clusters are unstaffed and are accessible 24 hours a day, 365 canicule a year.

Discuss

Discuss is a networked, cyberbanking conferencing system, agnate to the account lath programs begin on abounding computer systems.

Discuss uses the allegory of a appointment with abounding on-going meetings. As you ability expect, a “meeting” in Discuss is a discussion group with a specific focus (such as a accurate course, interesting quotes, harassment, area to acquisition chargeless food, Athena development, or any added affair of absorption to a accurate set of people). In Discuss, the anatomy the altercation takes is not exact conversations but accounting messages, accepted as “transactions”. Transactions are similar to email messages; in fact, in some cases you absolutely send transactions to the affair via email, although usually you enter transactions appliance options of a Discuss interface.

Kerberos

Kerberos is a arrangement affidavit arrangement for use on physically insecure networks, based on the key administration archetypal presented by Needham and Schroeder.[3] It allows entities communicating over networks to prove their character to anniversary added while preventing eavsdropping or epitomize attacks. It additionally provides for abstracts stream integrity (detection of modification) and clandestineness (preventing unauthorized reading) appliance cryptography systems such as DES.

Kerberos works by accouterment principals (users or services) with tickets that they can use to analyze themselves to added principals and abstruse cryptographic keys for defended advice with other principals.[1] A admission is a arrangement of a few hundred bytes. These admission can again be anchored in around any added network protocol, thereby acceptance the processes implementing that protocol to be abiding about the character of the principals involved.

Language learning

In the Athena Accent Acquirements Project, founded by Dr. Murray and foreign-language adroitness associates Claire Kramsch and Douglas Morgenstern, the motive was to analyze how multimedia technology could be acclimated to accomplish acquirements a adopted accent added accurate to life.

By creating documentaries or anecdotal belief that are filmed on location, appliance built-in speakers, the accent apprentice is accustomed a context that is afterpiece to what would be accomplished in the country itself. On a computer, these narratives can be affiliated to a array of supporting assets and anniversary apprentice can apply a abundant accord of control over the acquirements process. Structuring the adventure so that the student can admission the aftereffect or chase aberrant paths adds even more action to become involved.

Out of the Accent Acquirements Activity came alternate videos for French and Spanish. A la challenge de Philippe is the adventure of a young announcer badly gluttonous an accommodation in Paris, while Dans le quartier St. Gervais explores the history and ability of one of the oldest Parisian neighborhoods; Gilberte Furstenberg, senior lecturer in French, was activity administrator for both. A abstruseness story propels No recuerdo, an alternate anecdotal and documentary for learning Spanish. Created by Douglas Morgenstern, chief academician in Spanish, it is set in Bogota, Columbia.

The antecedent ambition of this activity is to actualize a scaleable manageable ambiance of accessible NT workstations and possibly servers that is an addendum of our absolute accretion infrastructure. There are a cardinal of appearance and accoutrement in Athena that we will appetite to provided to users in this new environment, as able-bodied as third party software that vendors may or may not currently aftermath for NT. Additionally, there are all-encompassing modifications and add-ons that will have to be fabricated to Microsoft cipher and/or procedures in the areas of security and both book and arrangement management. It is absolutely possible for the workload of this activity to be aggregate with added institutions undertaking agnate initiatives, and accomplishment should be placed on establishing these accord aboriginal in the activity to acquire the highest amount of account from collective efforts.

Patriot

On June 25, 1993, Advice Systems decomissioned the VAX 9000, patriot.mit.edu. The apparatus provided an beginning “compute server” account to Athena users from Fall 1992 until its shutdown.

Patriot was run as a timesharing apparatus with Athena services layered on top of Digital’s VAX ULTRIX. An IS-developed program, submit, let users abide accumulation jobs to Patriot, and booty advantage of its ample disks and RAM, as able-bodied as basically absolute program runtime.

We surveyed a accidental sample of the about 400 users of the Patriot service to actuate how the arrangement was used, and what kinds of similar casework Athena users may charge in the future. Though abounding of those surveyed anticipation the account was useful, we begin that we weren’t able to accommodate it in a reliable, cost-effective manner.
