15-410 AFS space

Location

Your AFS volume for 15-410 is located at /afs/cs.cmu.edu/academic/class/15410-f03/usr/$USER. Since this volume is in the CS cell, you will need to use cross-cell authentication. Luckily, this is easy. Whenever you log in to an Andrew machine, or use kinit to get new tickets, run afslog cs.cmu.edu. This has been tested to work on both Solaris (unix3.andrew) and Linux (unix47.andrew).

AFS problems

If you have permission problems with your AFS space, please try the program we have developed to diagnose them:

% /afs/cs.cmu.edu/academic/class/15410-f03/pub/access_scratch

DO NOT SEND US MAIL saying "I am having trouble accessing my AFS space". You must always provide us with a detailed explanation of the problem, such as a transcript of your session showing what you tried. Of course, you should not mail us the transcript; as with anything else, you should place it in a location where we can access it and tell us where that is.

If access_scratch does fix things for you, its output should give you a clue as to what you could do in the future to avoid the trouble.

Please note that AFS, like anything else, may break from time to time. If you receive errors such as Connection timed out or No such device, please wait one hour before sending us mail--these outages frequently resolve themselves (or are resolved by elves).

AFS layout

Inside your volume you will see multiple directories. With two exceptions, these are your hand-in directories. We have provided two directories for you to use while you are preparing your assignments:

REPOSITORY: You may place a CVS or PRCS repository here for Project 1 if you wish.
scratch: You may organize this directory tree any way you find convenient.

You should probably not prepare your work in your hand-in directories, since that would preclude you having a "safe" turned-in version while making changes to a version under (dare I say it?) last-minute development.
