rpcbind - universal addresses to RPC program number mapper
rpcbind [-d] [-w]
rpcbind 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 con-
tacts rpcbind on the server machine to determine the address
where RPC requests should be sent.
rpcbind should be started before any other RPC service.
Normally, standard RPC servers are started by port moni-
tors, so rpcbind must be started before port monitors are
When rpcbind 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,
rpcbind reports the condition and terminates.
rpcbind can only be started by the super-user.
The following options are supported:
-d Run in debug mode. In this mode, rpcbind will not fork
when it starts, will print additional information dur-
ing operation, and will abort on certain errors. With
this option, the name-to-address translation con-
sistency checks are shown in detail.
-w Do a warm start. If rpcbind aborts or terminates on
SIGINT or SIGTERM, it will write the current list of
registered services to /tmp/portmap.file and
/tmp/rpcbind.file. Starting rpcbind with the -w option
instructs it to look for these files and start opera-
tion with the registrations found in them. This allows
rpcbind to resume operation without requiring all RPC
services to be restarted.

Terminating rpcbind with SIGKILL will prevent the warm-
start files from being written.
All RPC servers must be restarted if the following occurs:
rpcbind crashes (or is killed with SIGKILL) and is unable
to to write the warm-start files; rpcbind is started without
the -w option after a graceful termination; or, the warm-
start files are not found by rpcbind.
