The Network File System protocol is similar to SMB, and commonly used between Unix systems. Version 4 requires password authentication and standardizes UDP or TCP port 2049, and port 111. Since authentication uses UID/GIDs and the server/client may not have the same mapping, this protocol should only be used on trusted networks.
