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

NAME
     atmarpd --	ATMARP/SCSP interface daemon

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

DESCRIPTION
     The atmarpd utility provides an interface between the ATMARP server in
     the kernel	and the	SCSP daemon for	the Host ATM Research Platform (HARP)
     networking	software.  The atmarpd utility 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 syn-
     chronization 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>  Specify that atmarpd is to write log messages to the file
		    named <log_file> rather than to the	system log.

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

     <net_intf>	    Specify 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.  The	atmarpd	utility	writes
	     a summary of its control blocks to	this file when it receives a
	     SIGINT signal.  <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.
