NAME
rpcbind
- universal addresses to RPC program number mapper
SYNOPSIS
[-6adiLls
]
[-h bindip
]
DESCRIPTION
The
utility is a server that converts
RPC
program numbers into
universal addresses.
It must be running on the host to be able to make
RPC
calls
on a server on that machine.
When an
RPC
service is started,
it tells
the address at which it is listening,
and the
RPC
program numbers it is prepared to serve.
When a client wishes to make an
RPC
call to a given program number,
it first contacts
on the server machine to determine
the address where
RPC
requests should be sent.
The
utility should be started before any other RPC service.
Normally, standard
RPC
servers are started by port monitors, so
must be started before port monitors are invoked.
When
is started, it checks that certain name-to-address
translation-calls function correctly.
If they fail, the network configuration databases may be corrupt.
Since
RPC
services cannot function correctly in this situation,
reports the condition and terminates.
The
utility can only be started by the super-user.
OPTIONS
-6
Bind to AF_INET6 (IPv6) addresses only.
-a
When debugging
(-d
)
do an abort on errors.
-d
Run in debug mode.
In this mode,
will not fork when it starts, will print additional information
during operation, and will abort on certain errors if
-a
is also specified.
With this option, the name-to-address translation consistency
checks are shown in detail.
-h bindip
Specify specific IP addresses to bind to for TCP and UDP requests.
This option
may be specified multiple times and is typically necessary when running
on a multi-homed host.
If no
-h
option is specified,
will bind to
INADDR_ANY
which could lead to problems on a multi-homed host due to
returning a UDP packet from a different IP address than it was
sent to.
Note that when specifying IP addresses with
-h
will automatically add
127.0.0.1
and if IPv6 is enabled,
::1
to the list.
-i
``Insecure''
mode.
Allow calls to SET and UNSET from any host.
Normally
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.
-L
Allow old-style local connections over the loopback interface.
Without this flag, local connections are only allowed over a local socket,
/var/run/rpcbind.sock
-l
Turn on libwrap connection logging.
-s
Cause
to change to the user daemon as soon as possible.
This causes
to use non-privileged ports for outgoing connections, preventing non-privileged
clients from using
to connect to services from a privileged port.
NOTES
All RPC servers must be restarted if
is restarted.
