The problem is that I'm unable to mount an NFS4-exported filesystem on
the client. Initially, the server rejected the NFS request. Now, RPC
is rejecting the connection.
Two X86 32-bit PCs, connected via wireless wlan0. Kernel on both systems
is 3.1.6-1.fc16.i686.PAE Connection is managed by NetworkManager.
Both systems are running an up-to-date Fedora 16. Rebooting does not
change the problem.
I would appreciate inshight as to what is happening.
As I'm reliably informed that a for all intents and purposes configuration
is working, I have to assume that it's something that I've done. But what?
===============
Detail.
First the setup.
Server:
% cat /etc/exports
/nfs4exports 192.168.0.0/24(ro,sync,insecure,root_squash,no_subtree_checck, fsid=0)
/nfs4exports/home 192.168.0.0/24(rw,nohide,sync,insecure,root_squash,no_subrree_ check)
% ls -ld /nfs4exports/ /nfs4exports/*
drwxrwxrwt 5 root root 4096 Dec 31 15:34 /nfs4exports//
drwxrwxrwt. 6 root root 4096 May 18 2011 /nfs4exports/home/
root@mtranch[148]->systemctl -a |grep nfs

Client:

firewall is disabled on both systems.
Here's what happened first -- when the NFS connection was rejected
