<h2 id="WhatisAFS">What is AFS?</h2>
<p>
-<strong>AFS</strong> (previously the <strong>Andrew File System</strong> or ) is a distributed network file system invented at <a href="http://www.cmu.edu/index.shtml">Carnegie Mellon University</a> 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.)

This folder is a link to a read-only copy of a backup of your files (created nightly around 3 a.m.). This copy cannot be edited and does not count against the locker's quota. From a technical standpoint, this is a separate volume with .backup appended (e.g. user.<username>.backup ) and is stored only as changes against the current copy.

-Where you should put a website, if you want one. There is very little special about this directory from an AFS standpoint, but it is world-readable (like Public) and is linked directly to <tt>http://www.mit.edu/~<lockername></tt> as well as <tt>http://web.mit.edu/<lockername>/www/</tt>.

<h2 id="AccessingLockers">Accessing Lockers</h2>
<h3 id="FromAthena">From Athena</h3>
On Athena, you can access a locker either as its full AFS path, if you know it (e.g. <tt>/afs/athena.mit.edu/course/6/6.01</tt>), or under <tt>/mit</tt> 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 <tt>/mit</tt>. There are a few ways to attach a locker:
</p>
-<ul><li>If you are running on a <a href="http://debathena.mit.edu">Debathena</a> machine, such as <a href="http://linerva.mit.edu">linerva.mit.edu</a>, then simply <tt>cd /mit/<locker></tt> and it will be auto-attached.
+<ul><li>If you are running on a <a href="http
s://debathena.mit.edu">Debathena</a> machine, such as <a href="http://linerva.mit.edu">linerva.mit.edu</a>, then simply <tt>cd /mit/<locker></tt> and it will be auto-attached.
</li><li>If you are on another Athena machine and don't want to run software out of the locker, than simply type <tt>attach <locker></tt> and then <tt>cd</tt> to it.
</li><li>If, however, you want to use software in the locker, you will be better served by running <tt>add <locker></tt> (e.g. <tt>add ruby-lang</tt>). This will attach the locker at <tt>/mit/<locker></tt> and will add the <tt>bin</tt> directory (for your architecture) of that locker to your PATH and the <tt>man</tt> directory to your MANPATH. What this means is that you should be able to run any program located in that locker by simply typing the name of the program at the command line.
</li></ul></li></ul><h3 id="FromtheWeb">From the Web</h3>
<p>
-Generally any locker that you would access on Athena as <tt>/mit/<locker></tt> is accessible on the web as <tt>http://web.mit.edu/<locker></tt>. For example, the barnowl locker is at <a href="http://web.mit.edu/barnowl">http://web.mit.edu/barnowl</a>. 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 <tt>www</tt> and <tt>Public</tt> folders.

-Also, you may access something in one of the MIT AFS cells by typing its full AFS path after web.mit.edu (<a href="http://web.mit.edu/afs/athena.mit.edu/activity/c/chess-club">http://web.mit.edu/afs/athena.mit.edu/activity/c/chess-club</a>). (That link also shows that if you have a text file named README readable, as a link to Public/README for example, its contents will be displayed below the directory listing).

-There may be a non-scheduled AFS outage. Check <a href="http://3down.mit.edu">3down</a>, hopefully it will be back up soon :-(. You can check up on the AFS servers by running <tt>fs checkservers</tt> (or <tt>fs checks</tt>). If there is no reported outage and you can't access the AFS servers (but can access the rest of the net), contact <a href="http://ist.mit.edu/services/athena/olh">OLC</a>.
