ATMARPD(8)		FreeBSD	System Manager's Manual		    ATMARPD(8)

NAME
     atmarpd --	ATMARP/SCSP interface daemon

SYNOPSIS
     atmarpd [-d] [-l <log_file>] <net_intf> ...

DESCRIPTION
     Atmarpd provides an interface between the ATMARP server in	the kernel and
     the SCSP daemon for the Host ATM Research Platform	(HARP) networking
     software.	Atmarpd	reads the ATMARP cache from the	kernel periodically
     and passes	any updated entries to scspd(8)	so they	will be	propagated to
     remote servers.  It also accepts updated entries that remote servers have
     sent to scspd(8) and, if they are new or more up to date than current
     entries, installs them in the kernel's ATMARP cache.  Both	atmarpd	and
     scspd(8) must be running before any ATMARP	cache synchronization can take
     place.

     When atmarpd starts, it parses its	command	line and puts itself into the
     background.

     The command-line options are:

     -l	<log_file>  Specifies that atmarpd is to write log messages to the
		    file named <log_file> rather than to the system log.

     -d		    Specifies that atmarpd is to be run	in debug mode.	In
		    debug mode,	atmarpd	is not put into	the background.	 Log
		    messages are written to standard output instead of to the
		    log	file.

     <net_intf>	    Specifies the network interface(s) for which the host is
		    providing ATMARP service and whose caches are to be	syn-
		    chronized using SCSP.  If multiple network interface names
		    are	specified, atmarpd will	provide	an interface to
		    scspd(8) for the servers on	all the	specified interfaces.

SIGNAL PROCESSING
     The following signals can be used to control atmarpd:

     SIGINT  Dump debugging information	to a file.  When it receives a SIGINT
	     signal, atmarpd dumps a summary of	its control blocks to a	text
	     file (see FILES).

FILES
     /tmp/atmarpd.<pid>.<seq>.out
	     Debugging information dump	file name.  Atmarpd writes a summary
	     of	its control blocks to this file	when it	receives a SIGINT sig-
	     nal.  <pid> is the	process	ID of the daemon and <seq> is a
	     sequence number which is incremented every	time a dump is taken.

BUGS
     Results are unpredictable if multiple instantiations of atmarpd are run
     simultaneously for	a given	network	interface.
