apols Matt, I didn't get this meaning from your original emails. Referrals certainly won't help you here, as once the referral occurs, the client talks only to the referred server.

However I have no access to the NFS > server Other than the obvious: watching the network, or taking your own (e.g. via rsync) copy of the main server's fs (assuming you have at least RO access) and sharing that, I can't think of anything off-hand. You could direct the client to a different port on your server, and use ssh port forwarding to redirect that to the main server, and then watch the packets on your server. cheers, calum.
