Uninstall rpcbind Package

package_rpcbind_removed

Description

The rpcbind utility maps RPC services to the ports on which they listen. RPC processes notify rpcbind when they start, registering the ports they are listening on and the RPC program numbers they expect to serve. The rpcbind service redirects the client to the proper port number so it can communicate with the requested service. If the system does not require RPC (such as for NFS servers) then this service should be disabled. The rpcbind package can be removed with the following command: 

$ sudo yum erase rpcbind

Rationale

If the system does not require rpc based services, it is recommended that rpcbind be disabled to reduce the attack surface.
