It must be running on the host to be able to make RPC calls. We will dive into RPCbind today to see how it works.
Remote Procedure Call RPC is an inter-process communication technique to allow client and server software to communicate on a network. The client makes a procedure call that appears to be local but is actually run on a remote computer.
During this process, the procedure call arguments are bundled and passed through the network to the server. The arguments are then unpacked and run on the server.
The result is again bundled and passed back to the client, where it is converted to a return value for the client's procedure call. Rpcbind accepts port reservations from local RPC services. These ports are then made available or advertised so the corresponding remote RPC services can access them. We will discuss more details later. When rpcbind is started, it checks that certain name-to-address translation calls function correctly. If they fail, the network configuration databases may be corrupt.
Since RPC services cannot function correctly in this situation, rpcbind reports the condition and terminates. Bruce Ediger Bruce Ediger The biggest issue in my case was that I I did not see a query to rcpbind on the server by the client when i was monitoring network traffic.
