After restarting the service, the ports have changed.

(9)

If you wish to control NFS you must fix the port settings in their  proper configuration files.  But since I am going to talk about other  protocols that route NFS through their ports, I will not lecture about  that now, but have attached the instructions on fixing the ports if you  wish to learn how do this.

Deamon RPM Standard PortRecommended Port Needs Changed?

Portmap Portmap 111 111 No

rpc.statd Nfs-utils Random 4000 Yes

rpc.nfsd Nfs-utils 2049 2049 No

rpc.lockd Nfs-utils and kernel Random 4001 Yes

rpc.mountd Nfs-utils Random 4002 Yes

rpc.rquotad Quota Random 4003 Yes

To change the rpc.statd port, edit the line in /etc/init.d/nfslock,  you must edit the start() function, under the line that says

something like “daemon rpc.statd”, you must add “­p 4000” to assign it port 4000, it is shown in the graphic under xemacs
