What is rpcbind service in Linux?
The rpcbind utility is a server that converts RPC program numbers into universal addresses. It must be running on the host to be able to make RPC calls on a server on that machine. When an RPC service is started, it tells rpcbind the address at which it is listening, and the RPC program numbers it is prepared to serve.

What is a rpcbind port?

What is the use of portmap service in Linux?
Portmap is a server that converts RPC program numbers into DARPA protocol port numbers. It must be running in order to make RPC calls. When an RPC server is started, it will tell portmap what port number it is listening to, and what RPC program numbers it is prepared to serve.

Can rpcinfo be used to make RPC calls to the NFS server?
In releases prior to SunOS 3.0, the Network File System (NFS) did not register itself with the portmapper; rpcinfo cannot be used to make RPC calls to the NFS server on hosts running such releases.
How do I configure rpcinfo to use a specific transport?
Specify the transport on which the service is required. If this option is not specified, rpcinfo uses the transport specified in the NETPATH environment variable, or if that is unset or null, the transport in the netconfig (5) database is used. This is a generic option, and can be used in conjunction with other options as shown in the SYNOPSIS.
