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

NAME
     portmap -- DARPA port to RPC program number mapper

SYNOPSIS
     portmap [-d] [-v] [-i address]

DESCRIPTION
     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).

     Options available:

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

     -v      (verbose) run portmap in verbose mode.

     -i address
             bind portmap to address. If you specify 127.0.0.1 it will bind to
             the loopback interface only.

     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 network 192.168. you could use the
     following line in /etc/hosts.allow:

     portmap: 192.168.

     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 only use the
     keyword ALL or IP addresses (NOT host or domain names).

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

BUGS
     If portmap crashes, all servers must be restarted.
