RPC: Program not registered

[Alfredo Cole <alfredo clshonduras com>]

Hi:

I have a server running RedHat 8.0, exporting a NFS directory.When trying to 
mount the directory on a locally connected workstation, I get the error:

mount: RPC: Program not registered.

My server's /etc/hosts.allow contains the line

portmap:	192.168.1.0/255.255.255.0

My iptables file looks like this:

# Generated by iptables-save v1.2.6a on Mon Nov 18 21:09:51 2002

What could be wrong?

Thank you.
