[linux-help] Re: Debian NFS Question

["Clint A. Brubakken" <cabrubak@xxxxxxx>]

The problem is that the files are owned by (User ID) uid 1001 and gid of
whatever console is on the the other boxes. 

When they look in the /etc/passwd and /etc/group files to see who they
belong on the other boxes they find that 1001 is not in the password
file and the gid corresponds to the console group. 
(the uid is the 3rd field in /etc/passwd and the gid is the 3rd field in
/etc/group

The problem is different /etc/passwd and /etc/group files on different
machines, that map the uid and gid to different names. 

There are 2 solutions. Either have the same uid and gid entry in all
/etc/passwd and /etc/group files, but since the gid is already used by 
by the other boxes, so replacing it would probably break some things.
Change the gid on the server to something that will work on both, and
chgrp any files that had that old group.

Second use NIS, which everyone says not to do and I have no experience
setting up

I thought there was a third but it seems uid and gid are not options
when mounting nfs
