     rpcbind - universal addresses to RPC program number mapper

     rpcbind [-dilLs]

     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,
     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

     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.

     -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

     -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
             connections, 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

     All RPC servers must be restarted if rpcbind is restarted.

     /etc/hosts.allow       explicit remote host access list.
     /etc/hosts.deny        explicit remote host denial of service list.
