Hello,

the nfsserver randomly chooses rpc ports for lockd and quotad.
This can be a major problem if the nfsserver crashes and
the clients still hang on the wrong port.(after reboot)

(NFS hangs->client machine hangs)

I would propose a patch similar to this, where the configuration
for the ports is /etc/sysconfig/nfs

This is a hack which I usually apply to my nfsservers:

 modprobe nfsd
 if [ -n "$LOCKD_TCPPORT" ]; then
    /sbin/sysctl -w s.nfs.nlm_tcpport=$LOCKD_TCPPORT >/dev/null 2>&1
 fi
 if [ -n "$LOCKD_UDPPORT" ]; then
    /sbin/sysctl -w s.nfs.nlm_udpport=$LOCKD_UDPPORT >/dev/null 2>&1
 fi
 service nfsserver start
 if [ -z "$RQUOTAD_PORT" ] ; then
     service quotad start > /dev/null 2>&1
   else
    /usr/sbin/rpc.rquotad -p $RQUOTAD_PORT >/dev/null 2>&1
 fi

It could be done better,ok, but you you get the idea what I actually mean :)

Note: this is usefull to protect an nfsserver with a firewall too.

regards,

Martin
