Subject: [gentoo-user] Gentoo nfs server:Opensolaris client; error `security mode does not match'

I'm having a problem mounting a nfs share exported by my gentoo
server.  The client problem occurs on an opensolaris box running
2008-11 build 109. 

I have an ancient /etc/exports that may be way out of date... I
rarely use nfs.  But I've begun setting up a NAS that consists of an
OpenSolaris server with ZFS file sytem.

I hoped to use NFS to handle backs ups and other work between linux
boxes and solaris NAS, with windows boxes using CIFS.

It doesn't really make sense to mount the other way round, like
serving from OpenSol and client at gentoo host since a general backup
plan will be running from the Solaris box and effecting all lan

At least that was my first thought.  But really would like to
understand what is needed in either direction.

Here is the line from /etc/exports (on gentoo server):

This is the command [and result] from Opensolaris client:

   mount -F nfs -o ro reader:/pub /pub 
  nfs mount: security mode does not match the server exporting reader:/pub

I think it is some basic problem between the two NFS implementations
and even found a redhat bug saying as much here:

Those export lines (in the bug report) are vastly different than
mine.. I know next to nothing about what `should' be on those
lines.... I probably copy/pasted the one I'm using years ago from

So, there is some chance, probably even a good chance that its just
some dopey error of mine causing the problem.
