NetBSD 6.1.5 - man page for rpcbind (netbsd section 8)

RPCBIND(8)			   BSD System Manager's Manual			       RPCBIND(8)

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, 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 ter-
     minates.

     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 interface.

     -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-privi-
	     leged 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.
