How to prevent NFS server from registering to portmap

Question

I found how to unregister NFS server from portmap using rpcinfo -d, but I would like to force nfs not to register once it starts running

I mean - if I use the command service nfs restart - the server should not show at rpcinfo -p after the restart is complete

I'm using CentOS 6.5, NFS version 3

the reason why I need this is because I'm running a proxy server from the same machine as the NFS server. the proxy signs to portmap as nfs, and I want all NFS calls to be redirected to the NFS proxy and not the NFS server - and then the proxy will forward messages to the server

Answer 1

The nfs client by itself doesn't register at rpcbind. However, the service nfs start starts rpc-statd daemon, which registers at rpcbind. Thus you have to disable rpc-statd daemon.

Notice that rpc-statd is required for file locking protocol, used by nfs v3.
