NFS server not scannable

opensuse v11.3

I enabled a NFS server on a host, set up a couple of exports, opened the ports in the firewall.

When I open the NFS Client on another host and select “Choose”, there is popup that states “Scanning for hosts on this LAN…”. Then it returns an error “No NFS server found on your network. …” That’s funny because I had previously mounted the two exported directories already by entering the server name manually.

How do I get the NFS server to respond to an automated search?

On the client , type:

rpcinfo -p <server>

to make sure that nfs, mountd an portmapper are running on the server.
If they are, type

showmount -e <server>

to see the exported filesystems.
