     NAME    [Toc]    [Back]
	  nbpd - AppleTalk Name	Binding	Protocol daemon

     SYNOPSIS    [Toc]    [Back]
	  /usr/etc/appletalk/nbpd [ -D ] [ -x ]	[ -N ] [ -n ] [	-H ] [
	  defaultzone ]

     DESCRIPTION    [Toc]    [Back]
	  The nbpd daemon is a host daemon which manages AppleTalk
	  Name Binding Protocol	(NBP) requests and AppleTalk Zone
	  Information Protocol (ZIP) requests.	It listens on the
	  well-known Names Information Socket for NBP lookup requests
	  and on the ZIP socket	for ZIP	requests.  The daemon
	  maintains a table of named services registered by host
	  processes and	reports	these services when requested by
	  remote users.

	  The nbpd daemon creates two files upon its invocation:
	  /usr/adm/appletalk/names_table, the registered services
	  table	maintained by the daemon, and
	  /usr/adm/appletalk/nbp_pid, which contains the process ID of
	  the daemon.  These two files are removed before the daemon
	  starts.  They	are also removed whenever the daemon is	killed
	  with a SIGTERM signal	(which is sent at system shutdown
	  time).

	  The flags are	as follows:

	  defaultzone	the first zone name assigned to	the internal
			AppleTalk zone.	All services that do not
			explicitly set their zone name will be
			assigned to this zone.	  If the zone name
			that is	specified does not occur in the
			existing zone list for the network (as
			published by other routers), the default zone
			will be	picked and a message will be logged.
			If no zone name	is specified, and there	are
			other AppleTalk	routers, the default zone name
			will be	used.  Killing nbpd with a SIGUSR2
			will cause it to dump its table	of networks
			and associated zones to
			/usr/adm/appletalk/at_log.

	  -D		causes nbpd to run in the foreground, printing
			debugging information.

	  -x		causes nbpd to print debugging information in
			hexadecimal.

	  -N		makes nbpd not respond to GetNetInfo and
			ZipQuery requests.   This flag can be used
			when you have other routers and	you do not

			want K-Talk to act as a	router at all.

	  -n		is similar to -N, except that it will respond
			to GetNetInfo and ZipQuery requests until
			another	router is seen on the net.  This
			option is used for auto-configuration, where
			it is unsure whether K-Talk is the only
			AppleTalk router on the	network.

	  -H		puts nbpd into a mode where NBP	requests are
			not propagated between network interfaces.  If
			you have multiple interfaces, and you do not
			want to	have the nets logically	connected, you
			should use this	option,	as well	as specifying
			a -H to	rtmpd. The K-Talk machine will see
			services on all	networks, and clients on all
			networks will see services on the K-Talk
			machine, but clients on	a particular net will
			have no	access to services on other networks.

     FILES    [Toc]    [Back]

					A list of the processes
					currently registered.

	  /usr/etc/appletalk/services	File where nbpd	is started.
