associated changes that had to happen to make this possible as well as
bugs fixed along the way.
Bring in required TLI library routines to support this.
Since we don't support TLI we've essentially copied what NetBSD
has done, adding a thin layer to emulate direct the TLI calls
into BSD socket calls.
This is mostly from Sun's tirpc release that was made in 1994,
however some fixes were backported from the 1999 release (supposedly
only made available after this porting effort was underway).
The submitter has agreed to continue on and bring us up to the
1999 release.
Several key features are introduced with this update:
Client calls are thread safe. (1999 code has server side thread
safe)
Updated, a more modern interface.
Many userland updates were done to bring the code up to par with
the recent RPC API.
There is an update to the pthreads library, a function
pthread_main_np() was added to emulate a function of Sun's threads
library.
While we're at it, bring in NetBSD's lockd, it's been far too
long of a wait.
New rpcbind(8) replaces portmap(8) (supporting communication over
an authenticated Unix-domain socket, and by default only allowing
set and unset requests over that channel). It's much more secure
than the old portmapper.
Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
to support TI-RPC and to support IPV6.
Umount(8) is also fixed to unmount pathnames longer than 80 chars,
which are currently truncated by the Kernel statfs structure.

.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 indent
|
|
.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,

|
|
All RPC servers must be restarted if
|
|
.Nm
|
|
is restarted.
