hi david...
thanks for the reply.. your answer confirmed what i had started to think
about. and yeah, you're right regarding only a few boxes for a home use..
however, i'm probably going to have 10-15 boxes running this app... but if
the issue really boils down to the user/group id then i could essentially
create a user with the same uid/gid on all boxes, or i could simply only
allow files to be created and added to the nfs share by the machine that
created the share...
this whole process is for use in a Condor system, where each node will be
performing some of the distributed applications.
thanks

That's not how NFS works. You need to have the same user ID
(numerical), and that's it. The local box associates a user name and
password with local users.
i.e. user 500 is use 500 on both boxes (unless you remap user IDs across
NFS). It doesn't matter whether use 500 is john on one and fred on the
other. And the passwords aren't compared, either.
If you've set boxes up so that you end up being user 500 on one of them,
but 501 on another, you're different users on both. You've either got
to do some user ID remapping between boxes through NFS (I've no advice
on how to do that to give you), or you change users on one of the boxes
to match.
Actually, the preferred solution is to use NIS and have a single login
to network resources. Using NIS allows the UIDs and GIDs to be
administered on a single box. That being said, its somewhat overkill
for home users and just making sure the UIDs and GIDs are the same on a
couple of boxes isn't all that bad.
Cheers,
Dave
