PORTMAP(8)               BSD System Manager's Manual                PORTMAP(8)


     portmap -  DARPA port to RPC program number mapper


     portmap [-d]


     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.
     When a client wishes to make an RPC call to a given program number, it
     will first contact portmap on the server machine, port PMAP_PORT (defined
     in <rpc/pmap_prot.h> to 111) to determine the port number where RPC pack-
     ets should be sent.

     portmap must be started before any RPC servers are invoked.

     Normally portmap forks and dissociates itself from the terminal like any
     other daemon. portmap then logs errors using syslog(3).

     Option available:

     -d      (debug) prevents portmap from running as a daemon, and causes er-
             rors and debugging information to be printed to the standard er-
             ror output.


     inetd.conf(5), inetd(8), rpcinfo(8)


     The portmap command appeared in 4.3BSD


     If portmap crashes, all servers must be restarted.
