for NFS too
Authored by: Mark Barton on Oct 26, '05 07:54:23AM
Another case that I found where UIDs are important is with NFS (the Unix network file-sharing system). They have it set up so that to access the files on the Unix cluster at work, the UID of the account on my PowerBook has to match the UID of my work account (but no other password protection or the like). Every so often when I have to do a complete system reinstall due to bad corruption or a new computer, I let the installer create the default admin account at UID=501 then use the above procedure to change it to 382. I also take the opportunity to change my shell to tcsh and I use the following tcsh command to renumber any files that have been created under the old number

sudo find / -user 501 -exec chown 382 '{}' ;

we use an xserve connected to a couple of xraids for a Network Attached Storage. All of our network servers a unix/linuxed/hpux based connect to the NAS via NFS.

In order for all of these different servers to share storage on the NAS, we insure that each user account UID is consistant. This has all but eliminated any permissions issues we had. This was pretty easy to do as we have most of the servers authenticating to the Open Directory services on the xserve.

UID matching applescript

I scripted a solution for this to ease AFS usage during our migration to OSX. It's called uidMatch and it's available at my website. Source included.

NFS Lacie Ethernet Disk RAID
Authored by: Pythonista on Feb 26, '07 05:02:43AM

I have a Lacie Ethernet Disk RAID that I want to access from Powerbooks using NFS. How can I see the UID and GID on the Lacie? How do I create a new uid on the Mac? What is the step by step procedure to make all this work? I am connected to the NFS folder in the finder but I don't have enough permission to work with it.
