Hi all

We are using an amd64 linux box as an NFS server with a firewall. We have
opened ports 111 for portmapper and 2049 for NFS.

Our first problem was to let rpc.mountd operate but worked out how to do
that by editing /etc/defaults/nfs-kernel-server to add

RPCMOUNTDOPTS="-p 32478"

So that it always starts on that port.

Ouput of rpcinfo -p is now:

root@Athlon:~# rpcinfo -p
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100003 4 udp 2049 nfs
100003 2 tcp 2049 nfs
100003 3 tcp 2049 nfs
100003 4 tcp 2049 nfs
100021 1 udp 32768 nlockmgr
100021 3 udp 32768 nlockmgr
100021 4 udp 32768 nlockmgr
100021 1 tcp 33621 nlockmgr
100021 3 tcp 33621 nlockmgr
100021 4 tcp 33621 nlockmgr
100005 1 udp 32478 mountd
100005 1 tcp 32478 mountd
100005 2 udp 32478 mountd
100005 2 tcp 32478 mountd
100005 3 udp 32478 mountd
100005 3 tcp 32478 mountd
100024 1 udp 828 status
100024 1 tcp 831 status


Everything is working except occasional problems with file locking. I
realised that this is because nfslock/nlockmgr/rpc.lockd is still assigning
random ports at each startup.

The question is:

How do we fix the other ports - particularly nlockmgr?

Otherwise we have to change firewall setup on each reboot.

Have looked in /etc/defaults/ & /etc/init.d/ but can't find anything there
or in man pages, documentation or on google.

Anyone have any ideas?

TIA

Michael

I have never done anything with nfs, but I wonder if these two links
apply to your situation:
