The rpc file is a local source containing user readable names that can be used in place of RPC program numbers. The rpc file can be used in conjunction with or instead of other rpc sources, including the NIS maps ``rpc.byname'' and ``rpc.bynumber''.
The rpc file has one line for each RPC program name. The line has the following format:
name-of-the-RPC-program RPC-program-number aliases
Items are separated by any number of blanks and/or tab characters. A ``#'' indicates the beginning of a comment; characters up to the end of the line are not interpreted by routines which search the file.
Below is an example of an RPC database:
# # rpc # rpcbind 100000 portmap sunrpc portmapper rusersd 100002 rusers nfs 100003 nfsprog mountd 100005 mount showmount walld 100008 rwall shutdown sprayd 100012 spray llockmgr 100020 nlockmgr 100021 status 100024 bootparam 100026 keyserv 100029 keyserver
