.Nm portmap

.Sh DESCRIPTION
|
|
.Nm Portmap
|
|
is a server that converts
|
|
.Tn RPC
|
|
program numbers into
|
|
.Tn DARPA
|
|
protocol port numbers.
|
|
It must be running in order to make
|
|
.Tn RPC
|
|
calls.
|
|
.Pp
|
|
When an
|
|
.Tn RPC
|
|
server is started, it will tell
|
|
.Nm
|
|
what port number it is listening to, and what
|
|
.Tn RPC
|
|
program numbers it is prepared to serve.
|
|
When a client wishes to make an
|
|
.Tn RPC
|
|
call to a given program number,
|
|
it will first contact
|
|
.Nm
|
|
on the server machine to determine
|
|
the port number where
|
|
.Tn RPC
|
|
packets should be sent.
|
|
.Pp
|
|
.Nm Portmap
|
|
must be started before any
|
|
.Tn RPC
|
|
servers are invoked.
|
|
.Pp
|
|
.Nm Portmap
|
|
uses
|
|
.Xr hosts_access 5
|
|
access control by default.
|
|
Access control patterns may only reference IP addresses.
|
|
.Pp
|
|
Normally
|
|
.Nm
|
|
forks and dissociates itself from the terminal
|
|
like any other daemon.
|
|
.Nm Portmap
|
|
then logs errors using
|
|
.Xr syslog 3 .
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width indent
|
|
.It Fl d
|
|
Prevent
|
|
.Nm
|
|
from running as a daemon,
|
|
and causes errors and debugging information
|
|
to be printed to the standard error output.
|
|
.It Fl v
|
|
Enable verbose logging of access control checks.

|
|
.Nm
|
|
crashes, all servers must be restarted.
