I have tried a number of permutations in /etc/exports:
---------    1  -----------
/opt/ltsp/i386            192.168.0.0/255.255.255.0(ro,no_root_squash,sync)
/var/opt/ltsp/swapfiles   192.168.0.0/255.255.255.0(rw,no_root_squash,async)
----------   2  ----------------
/opt/ltsp/i386 *(ro,async,no_root_squash)
----------   3  -------------------------
/opt/ltsp *(ro,async,no_root_squash)
-------
All gave the exact same error messages, as described previously. The official
K12-Fedora instructions at
http://www.ltsp.org/~sbalneav/LTSPManual.html#id2526788
specifies only 1 line to put in /etc/exports, as shown
in the excerpt below:

6. Update NFS /etc/exports file.

echo "/opt/ltsp *(ro,async,no_root_squash)" >>/etc/exports


I can attest to the fact that this worked for several months, and only stopped
working over the Xmas holidays, after I updated my Fedora9 server.


I have tested these /etc/exports files with iptables and ip6tables turned off,
so it doesn't appear to be a firewall issue.

By the way, when I try example 1 from above, I get the following output
from exportfs -v:

exportfs: No host name given with 
/var/opt/ltsp/swapfiles192.168.0.0/255.255.255.0(rw,no_root_squash,async) 
(ro,sync,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534), 
suggest 
*(ro,sync,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534) 
to avoid warning
/opt/ltsp/i386	192.168.0.0/255.255.255.0(ro,wdelay,no_root_squash,no_subtree_check)
/var/opt/ltsp/swapfiles192.168.0.0/255.255.255.0(rw,no_root_squash,async)
		<world>(ro,wdelay,root_squash,no_subtree_check)
