Hi Group,

Recently i deployed one NFS server(S1) with three clients(C1,C2,C3),
two client nodes successfully mount NFS server(S1) share into local
directory , but problem with client3 , when i tried to mount NFS
Server(S1) share directory in to local directory , it showed the
error message 'mount: RPC: Program not registered'.

# mount -o rsize=8192,wsize=8192 S1:/remote /local
mount: RPC: Program not registered

To minimize the complexity i add following line in /etc/hosts.allow in
NFS server(S1)

portmap:ALL


RHEL ver 3.0 installed on all machines.

Services running on machines
c1,c2,c3: portmap,rpc.mountd
s1: portmap,nfsd,rpc.rquotad,rpc.statd,rpc.mountd

Is portmap running on the machine attempting to mount the share from the server?

Yes , Portmap running on all servers

You keep saying servers but also the clients?

Yes client also..
Problem resolved

problem with /etc/hosts.allow portmap entry
portmap: 192168.0.0/24 (wrong)
portmap: 192.168.0.0/255.255.255.0

Thanks for your support

well i am open to all suggestion i have googled lots and lots.
any help appreciated thanks nige

both systems are running debian 3.1

ok folks the problem was /etc/hosts/deny i have basically wiped it clean and now it works no problem.I would guess from a security point of view thats not so good but i can work on that now.so if any body wants to throw a few tips my way on the best way for this file to look i would think that would be good.
thanks nige
