RPC Error: 15 ( Program not registered )

RPC Error: 15 ( Program not registered )

[Marten Lehmann]

Hello,

I'm experiencing exactly the problem as described at 
http://nfs.sourceforge.net/nfs-howto/troubleshooting.html

7.3b:  RPC: Program Not Registered: (or another "RPC" error)

The nfs server is running with version 3, the client has version 4.

rpcinfo -p on the server gives:

    program vers proto   port
     100000    2   tcp    111  portmapper
     100000    2   udp    111  portmapper
     100011    1   udp    604  rquotad
     100011    2   udp    604  rquotad
     100011    1   tcp    607  rquotad
     100011    2   tcp    607  rquotad

     100021    4   udp  32770  nlockmgr
     100021    1   tcp  33302  nlockmgr
     100021    3   tcp  33302  nlockmgr
     100021    4   tcp  33302  nlockmgr
     100005    1   udp    620  mountd
     100005    1   tcp    623  mountd
     100005    2   udp    620  mountd
     100005    2   tcp    623  mountd
     100005    3   udp    620  mountd
     100005    3   tcp    623  mountd

rpcinfo -p 192.168.33.53 from the client gives:

    program vers proto   port
     100000    2   tcp    111  portmapper

     100021    1   tcp  33302  nlockmgr
     100021    3   tcp  33302  nlockmgr
     100021    4   tcp  33302  nlockmgr
     100005    1   udp    620  mountd
     100005    1   tcp    623  mountd
     100005    2   udp    620  mountd
     100005    2   tcp    623  mountd
     100005    3   udp    620  mountd
     100005    3   tcp    623  mountd

For debugging, I disabled all firewalls. However, mounting is not 
successful:

# mount -t nfs 192.168.33.53:/vrmd/rhel4 /mnt -v
mount to NFS server '192.168.33.53' failed.
RPC Error: 15 ( Program not registered )

# mount -t nfs -o vers=3 192.168.33.53:/vrmd/rhel4 /mnt -v
mount to NFS server '192.168.33.53' failed.
RPC Error: 15 ( Program not registered )

What can I do? The Troubleshooting-Page reports the problem, but does 
explain how to solve the issue. Any ideas, what causes this problem?

Marten

Btw.:

on the server, I can see several lines like

Jun 14 22:02:16 vm3 rpc.mountd: authenticated mount request from 
192.168.33.56:792 for /vrmd/rhel4 (/vrmd/rhel4)

in /var/log/messages.
