Thanks for that. That's a very nice guide and I've bookmarked it. At least that explains the permissions I didn't recognize.
Anyway, an update
I reformatted the box and installed RHEL 4, same settings and options I've used on all of our current development and production servers, which all run RHEL 4.
Now, however, I can't even mount the shared space! I'm using the exact_same_fstab entries
that the other 5 servers use. They all mount, read, write fine, but this server complains about a permission error.
The entry on all six of the servers is:
//emc_fs_2/share_files$ /mnt/share_files2 cifs user=xxxxx,password=xxxxx
The error on this server is:
[root@rh-php-prod ~]# mount /mnt/share_files2
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
I've talked to the network guys, and there's nothing different about the network on which this server connects; it's the same as the other servers. They've double checked the EMC share settings, and there are no special permissions, just a single username/password combination.
