.TH PORTMAP 8C "9 September 1987"
|
|
.SH NAME
|
|
portmap \- DARPA port to RPC program number mapper
|
|
.SH SYNOPSIS
|
|
.B /usr/etc/rpc.portmap
|
|
.SH DESCRIPTION
|
|
.IX "portmap command" "" "\fLportmap\fP \(em DARPA to RPC mapper"
|
|
.IX DARPA "to RPC mapper \(em \fLportmap\fP"
|
|
.B portmap
|
|
is a server that converts
|
|
.SM RPC
|
|
program numbers into
|
|
.SM DARPA
|
|
protocol port numbers.
|
|
It must be running in order to make
|
|
.SM RPC
|
|
calls.
|
|
.LP
|
|
When an
|
|
.SM RPC
|
|
server is started, it will tell
|
|
.B portmap
|
|
what port number it is listening to, and what
|
|
.SM RPC
|
|
program numbers it is prepared to serve.
|
|
When a client wishes to make an
|
|
.SM RPC
|
|
call to a given program number,
|
|
it will first contact
|
|
.B portmap
|
|
on the server machine to determine
|
|
the port number where
|
|
.SM RPC
|
|
packets should be sent.
|
|
.LP
|
|
Normally, standard
|
|
.SM RPC
|
|
servers are started by
|
|
.BR inetd (8C),
|
|
so
|
|
.B portmap
|
|
must be started before
|
|
.B inetd
|
|
is invoked.

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

|
.BR inetd (8)
|
|
.SH BUGS
|
|
If
|
|
.B portmap
|
|
crashes, all servers must be restarted.
