troubleshooting. The

To make sure the proper NFS RPC-based services are enabled for

rpcinfo -p

The output from this command reveals that the correct NFS services are running. If one of the NFS
services does not start up correctly,
service to the correct port. In many cases, if NFS is not present in
causes the service to correctly register with
NFS, refer to Section 9.2 Starting and Stopping NFS.
Other useful options are available for the
more information.

9.2. Starting and Stopping NFS

To run an NFS server, the
the following command as root:
/sbin/service portmap status
If the service is running, then the
portmap
