[Cialug] Can't Edit Permissions on NFS Share

[Todd Walton]

The stuff from the HOWTO has all been checked. No further help there. The
NFS logs get turned on by "rpcdebug -m nfs all" (and turned off by
"rpcdebug -m nfs -c all"). When it's on messages show up in
/var/log/messages. Trying to chmod one file, I see this in
/var/log/messages:

Per the RFC, the reply setattr code of 13 is the point where it says
"permission denied". I don't know what the other stuff means.
