NAME
portmap
- DARPA
port to
RPC
program number mapper
SYNOPSIS
portmap
[-d
]
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).
Option available:
- -d
-
(debug) prevents
portmap
from running as a daemon,
and causes errors and debugging information
to be printed to the standard error output.

BUGS
If
portmap
crashes, all servers must be restarted.
