short enough to put on the same line. - Kill the comma at the end of SEE ALSO list. - Remove empty line in the source. - Break line at the end of statement in the source for better output (in other words, let the roff to format it).

.Sh NAME
|
|
.Nm rpcbind
|
|
.Nd universal addresses to RPC program number mapper
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl dilLs
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
is a server that converts
|
|
.Tn RPC
|
|
program numbers into
|
|
universal addresses.
|
|
It must be running on the host to be able to make
|
|
.Tn RPC
|
|
calls
|
|
on a server on that machine.
|
|
.Pp
|
|
When an
|
|
.Tn RPC
|
|
service is started,
|
|
it tells
|
|
.Nm
|
|
the address at which it is listening,
|
|
and the
|
|
.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 first contacts
|
|
.Nm
|
|
on the server machine to determine
|
|
the address where
|
|
.Tn RPC
|
|
requests should be sent.
|
|
.Pp
|
|
.Nm
|
|
should be started before any other RPC service.
|
|
Normally, standard
|
|
.Tn RPC
|
|
servers are started by port monitors, so
|
|
.Nm
|
|
must be started before port monitors are invoked.
|
|
.Pp
|
|
When
|
|
.Nm
|
|
is started, it checks that certain name-to-address
|
|
translation-calls function correctly.
|
|
If they fail, the network configuration databases may be corrupt.
|
|
Since
|
|
.Tn RPC
|
|
services cannot function correctly in this situation,
|
|
.Nm
|
|
reports the condition and terminates.
|
|
.Pp
|
|
.Nm
|
|
can only be started by the super-user.
|
|
.Sh OPTIONS
|
|
.Bl -tag -width Ds
|
|
.It Fl d
|
|
Run in debug mode.
|
|
In this mode,
|
|
.Nm
|
|
will not fork when it starts, will print additional information
|
|
during operation, and will abort on certain errors.
|
|
With this option, the name-to-address translation consistency
|
|
checks are shown in detail.
|
|
.It Fl i
|
|
.Dq insecure
|
|
mode.
|
|
Allows calls to SET and UNSET from any host.
|
|
Normally
|
|
.Nm
|
|
accepts these requests only from the loopback interface for security reasons.
|
|
This change is necessary for programs that were compiled with earlier
|
|
versions of the rpc library and do not make those requests using the
|
|
loopback interface.
|
|
.It Fl l
|
|
Turns on libwrap connection logging.
|
|
.It Fl s
|
|
causes
|
|
.Nm
|
|
to change to the user daemon as soon as possible.
|
|
This causes
|
|
.Nm
|
|
to use non-privileged ports for outgoing connections, preventing non-privileged
|
|
clients from using
|
|
.Nm
|
|
to connect to services from a privileged port.
|
|
.It Fl L
|
|
Allow old-style local connections over the loopback interface.
|
|
Without this flag, local connections are only allowed over a local socket,

.Sh NOTES
|
|
.Pp
|
|
All RPC servers must be restarted if
|
|
.Nm
|
|
is restarted.
