What is AFS?

-AFS (previously the Andrew File System or ) is a distributed network file system invented at Carnegie Mellon University as part of Project Andrew (approximately their equivalent of MIT's Project Athena). More importantly, it is the file system used to store most files on Athena today. This includes your personal home directory, the data and websites of many living groups and student groups on campus, and probably some of the software you run (if you ever use Athena clusters). (Though most user directories were migrated from NFS in the summer of 1992, some files still remain on NFS and, of course, various file systems are used on personal computers and servers.) +AFS (previously the Andrew File System or ) is a distributed network file system invented at Carnegie Mellon University as part of Project Andrew (approximately their equivalent of MIT's Project Athena).

Accessing Lockers

From Athena

@@ -89,7 +89,7 @@ Where you should put a website, if you want one. There is very little special ab On Athena, you can access a locker either as its full AFS path, if you know it (e.g. /afs/athena.mit.edu/course/6/6.01), or under /mit if it is "attached." Though you can always use the full path, you often want to attach lockers because it is easier to refer to them and software is set up to run with a path under /mit. There are a few ways to attach a locker:

-

From the Web

-Generally any locker that you would access on Athena as /mit/<locker> is accessible on the web as http://web.mit.edu/<locker>. For example, the barnowl locker is at http://web.mit.edu/barnowl. As you can see, if there is no index.html (see below), the files in the directory are listed. By default, however, none of the contents are readable except in the www and Public folders. +Generally any locker that you would access on Athena as /mit/<locker> is accessible on the web as https://web.mit.edu/<locker>.
