NAME
     rpcbind — universal addresses to RPC program number mapper

SYNOPSIS
     rpcbind [-dilLs]

DESCRIPTION
     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
     contacts 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, stan‐
     dard 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 transla‐
     tion-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.

     Access control is provided by /etc/hosts.allow and /etc/hosts.deny, as
     described in hosts_access(5) with daemon name rpcbind.

OPTIONS
     -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.  With this option, the name-to-
	     address translation consistency checks are shown in detail.

     -i	     “insecure” mode.  Allows 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 inter‐
	     face.

     -l	     Turns on libwrap connection logging.

     -s	     Causes rpcbind to change to the user daemon as soon as possible.
	     This causes rpcbind to use non-privileged ports for outgoing con‐
	     nections, preventing non-privileged clients from using rpcbind to
	     connect to services from a privileged port.

     -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

NOTES
     All RPC servers must be restarted if rpcbind is restarted.

FILES
     /var/run/rpcbind.sock
     /etc/hosts.allow	    explicit remote host access list.
     /etc/hosts.deny	    explicit remote host denial of service list.
