Thanks for your quickness!
The server is the redhat box and yes, it is serving up both samba (good catch!) and nfs.
There are exports for these nfs shares on the redhat box. Do I need them on the Ubuntu box (client) as well?
Not sure what you mean about mapping in a scalable way. My network consists of 3 Win boxes accessing the server via Samba, and 4 Ubuntu boxes accessing currently via cifs. I am thinking that I might speed up the Ubuntu accesses if I used nfs, and might eliminate some of the weirdness that Samba seems to bring in to the permissions.
So it would be relatively easy for me to change UIDs and GIDs on 4 Ubuntu boxes, or if necessary on the redhat server alone.
redhat's version of nfs is a bit older, and does not seem to support naming the uid and gid--at least when I try to use them in /etc/fstab, they are unrecognized. So I am not sure how to do anonuid and anongid.
What is behind this effort is that when the day comes that the redhat box finally gives up the ghost, I would like to know how to set up an Ubuntu box to take its place, pretty well seamlessly. So maybe I should be looking at changing the UIDs on the redhat box to match the Ubuntu boxes. What do you think?
Ahh! I found this when I looked in the server's /etc/exports file:
So I gather I had tried that once before. So I tried it again just now and and still get a permission denied error.
Also, tried an ls:
doug@doug2:~$ ls -alh /sam/vol22
?--------- ? ? ? ? ? /sam/vol22/.
Not sure if that is telling us anything helpful....
