NAME

     rpcbind -- portmap

SYNOPSIS

     rpcbind [-d] [-v] [-h bindip]

DESCRIPTION

     Rpcbind is a server that converts RPC program numbers into DARPA protocol port numbers.  It is a replacement for the older portmap program.

     rpcbind supports the original version 2 portmap protocol and in addition supports the newer version 3 and version 4 protocols that are neces-
     sary for IPv6 support.  It must be running on the server in order to make RPC calls.

     When an RPC server is started, it will tell rpcbind what address it is listening to, 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.

     rpcbind is a launchd service. When the first server tries to register with rpcbind the RPC library will contact launchd and arrange for
     rpcbind to be started.  Note it is no longer possible to run rpcbind from the command line.  rpcbind logs errors and information using
     asl(3).  rpcbind uses hosts_access(5) for access control; note access control patterns may only reference IP addresses.

     The following options are available and will need to be added to the rpcbind plist file.

     -d      causes rpcbind errors and debugging information to be printed to the standard error output via asl_log. This option is no longer very
	     useful.

     -v      Enable verbose logging of access control checks.

     -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 to the list.

FILES

     /System/Library/LaunchDaemons/com.apple.rpcbind.plist  launchd.plist(5) file for rpcbind.	Options should be added here.

     /usr/share/sandbox/rpcbind.sb			    sandbox(7) file for rpcbind.

SEE ALSO

     hosts_access(5), launchd.plist(5), launchd(8), rpcinfo(8)

BUGS

     If rpcbind crashes, all servers must be restarted.

     Version 4 getstat procedure is not implemented and will always return 0 and null values.  RPC_SYSTEMERROR.

     -h option is not supported for IPv6.

NAME

       rpcbind - universal addresses to RPC program number mapper

SYNOPSIS

DESCRIPTION

       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 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 on the server machine to determine the address where RPC
       requests should be sent.

       should be started before any other RPC service.	Normally, standard RPC servers are started by port monitors, so  must  be  started  before
       port monitors are invoked.

       When  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, reports the condition and terminates.

       can only be started by the super-user.

   Options
       recognizes the following options:

	      Run in debug mode.
			In this mode, 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.

	      Do a warm start.
			If  aborts  or	terminates  on	or  it	will write the current list of registered services to and Starting with the option
			instructs it to look for these files and start operation with the registrations found in  them.   This	allows	to  resume
			operation without requiring all RPC services to be restarted.

WARNINGS

       Terminating with will prevent the warm-start files from being written.

       All  RPC  servers  must be restarted if the following occurs: crashes (or is killed with and is unable to to write the warm-start files; is
       started without the option after a graceful termination; or, the warm-start files are not found by
