RPC program number database
The rpc file contains user-readable names that can be used in place of rpc program numbers. Each line has the following information:
name_of_server_for_rpc_program rpc_program_number aliases
Items are separated by any number of blanks or tabs, or both. A pound sign (#) in a line indicates the beginning of a comment -- any characters after a #, up to the end of the line, aren't interpreted by routines that search the file.
