NAME

     rpcbind - universal addresses to RPC program number mapper

SYNOPSIS

     rpcbind [-adhiLls]

DESCRIPTION

     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
     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.

     The rpcbind utility can only be started by the super-user.

OPTIONS

     -a      When debugging (-d), do an abort on errors.

     -d      Run in debug mode.  In this mode, rpcbind 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      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
             terminates.

NOTES

     All RPC servers must be restarted if rpcbind is restarted.
