I'm using a proxy server that acts like NFS server. its currently installed on the same machine as the actually nfs server - so I want to change the servers listener setting so I won't clash with the proxy NFS server.
so I've changed the port my NFS server listens on to 2050 ( default was 2049 ) at /etc/nfsmount.conf.
now I would like to unregister the NFS server from the Portmap.
the portmap manual has nothing about this and I couldn't find a configuration file for it.
thanks to @nos I've found that I can use rpcinfo -d PROG_NUMBER VERSION to unregister a program from the portmap
