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

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 necessary 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 pro-gram program
     gram numbers it is prepared to serve.  When a client wishes to make an RPC call to a given program num-ber, number,
     ber, 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 multi-ple multiple
             ple 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.
