rpcbind — universal addresses to RPC program number mapper
rpcbind [-adhiLls]
The rpcbind 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 rpcbind 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 rpcbind on the server machine to determine the address
where RPC requests should be sent.
The rpcbind utility should be started before any other RPC service.
Normally, standard RPC servers are started by port monitors, so rpcbind
must be started before port monitors are invoked.
When rpcbind is started, it checks that certain name-to-address trans‐
lation-calls function correctly. If they fail, the network configura‐
tion databases may be corrupt. Since RPC services cannot function cor‐
rectly in this situation, rpcbind reports the condition and terminates.
The rpcbind utility can only be started by the super-user.
-a When debugging (-d), do an abort on errors.
-d Run in debug mode. In this mode, rpcbind will log 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.
-f Do not fork and become a background process.
-h Specify specific IP addresses to bind to for 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, rpcbind will bind to INADDR_ANY, which could lead
to problems on a multi-homed host due to rpcbind returning a
UDP packet from a different IP address than it was sent to.
Note that when specifying IP addresses with -h, rpcbind 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 rpcbind 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 Turn on libwrap connection logging.
-s Cause rpcbind to change to the user daemon as soon as possible.
This causes rpcbind to use non-privileged ports for outgoing
connections, preventing non-privileged clients from using
rpcbind to connect to services from a privileged port.
-w Cause rpcbind to do a "warm start" by read a state file when
rpcbind starts up. The state file is created when rpcbind ter‐
minates.
All RPC servers must be restarted if rpcbind is restarted.
