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

     portmap --	DARPA port to RPC program number mapper

     portmap [-d] [-v]

     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 to determine the port
     number where RPC packets 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.

     -v	     (verbose) run portmap in verbose mode.

     This portmap version is protected by the tcp_wrapper library. You have to
     give the clients access to	portmap	if they	should be allowed to use it.
     To	allow connects from clients of the domain you could use the
     following line in /etc/hosts.allow:


     You have to use the daemon	name portmap for the daemon name (even if the
     binary has	a different name). For the client names	you can	use the	key-
     word ALL, IP addresses, hostnames or domain names.

     For further information please have a look	at the tcpd((8)),
     hosts_allow((5)) and hosts_access((5)) manual pages.

     xinetd.conf((5)), rpcinfo((8)), pmap_set((8)), pmap_dump((8)),
     xinetd((8)) tcpd((8)) hosts_access((5)) hosts_options((5))

     If	portmap	crashes, all rpc servers must be restarted.

     The portmap command appeared in BSDBSD 4.3.
