rpcbind(1M)                                                     rpcbind(1M)

NAME
     rpcbind - universal addresses to RPC program number mapper

SYNOPSIS
     rpcbind [-d] [-o]

DESCRIPTION
     rpcbind is a server that converts RPC program numbers into universal
     addresses. It must be running to make RPC calls.

     When an RPC service is started, it will tell rpcbind at what address
     it is listening, and what RPC program numbers it is prepared to serve.
     When a client wishes to make an RPC call to a given program number, it
     will first contact rpcbind on the server machine to determine the
     address where RPC packets should be sent.

     Normally, standard RPC servers are started by port monitors, so
     rpcbind must be started before port monitors are invoked.

     rpcbind is restricted to users with appropriate privileges.

OPTIONS
     -d   Debug mode. Shows status messages.

     -o   Previous behavior. The old Portmapper protocol has a well known
          security problem for which a solution now exists. If old RPC
          servers cannot log on to rpcbind ("weak authorization") with the
          Portmapper protocol, this option will allow the old (unsafe) pro-
          cedure to be reactivated. In general, however, it is not recom-
          mended to use this option!

NOTES
     If rpcbind crashes, all RPC servers must be restarted.
