AFS is a distributed filesystem product, pioneered at Carnegie Mellon
University and supported and developed as a product by Transarc
Corporation (now IBM Pittsburgh Labs). It offers a client-server
architecture for file sharing, providing location independence,
scalability and transparent migration capabilities for data.
IBM branched the source of the AFS product, and made a copy of the
source available for community development and maintenance. They called
the release OpenAFS.
IT Services has put together an OpenAFS installer that will install both
the OpenAFS package and the necessary configuration files for using
OpenAFS at Iowa State.
Download the appropriate version of OpenAFS for your version of Mac OS X:
If the downloaded file wasn't automatically mounted, then double-click
on the .dmg file to mount the disk image. Then double-click on the
OpenAFS.mpkg package installer to install and configure OpenAFS.
Mac OS X 10.3: Accessing Your AFS Files
You do not need to do the following steps for Mac OS X 10.4 or 10.5.
If you are having trouble getting full read-write access to your files
on AFS, you may want to set your local uid to match that of your uid
that is used on the AFS file system. To ease this process, we strongly
recommend you have an Administrator account that is not the
same as the one you are using to access the AFS file system.
Login with an Administrator account that is not the one you are
changing the uid on.
Enter the following command in Terminal
(/Applications/Utilities/) to find the uid number:
pts examine net-id
where net-id is your Iowa State Net-Id (or the Net-Id of the AFS
user you are chaning the uid of).
Write down the "id:" number from the output of this command. This is your
new-uid.
Run "NetInfo Manager" (/Applications/Utilities/)
In the left column, select /
In the middle column, select users
In the right column, select your net-id
Authenticate by clicking the lock icon (on the bottom left-hand
corner of the window) that is next to the text that says "Click the lock
to make changes".
Under the "Property" list, find the line that contains "uid".
Write down the "Value" number. This is your old-uid.
Double-click the uid value and change it to the new-uid value.
Save your changes (Domain -> Save Changes) and quit NetInfo Manager.
Enter the following command in Terminal (/Applications/Utilities)
to set the appropriate file ownership permissions:
replacing old-uid and new-uid in this command with the
values that you wrote down.
If you have any other drives connected to your machine, enter the
above command to correct file ownership permissions there too. But, in
place of / in the command use
/Volumes/volume-name, where volume-name is
the name of the drive. For example, for the "Stuff" drive, you would
use /Volumes/Stuff.
