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)
