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

NAME
     arpsnmp --	keep track of ethernet/ip address pairings

SYNOPSIS
     arpsnmp [-dqs] [-D	arpdir]	[-f datafile] [-w watcher@email]
	     [-W watchee@email]	file ...

DESCRIPTION
     arpsnmp keeps track of ethernet/ip	address	pairings. It syslogs activity
     and reports certain changes via email.  arpsnmp reads information from a
     file (usually generated by	snmpwalk(3)).

     The format	of the input file is the same as arp.dat; the mac address, ip
     address, optional timestamp and optional simple hostname. If the time-
     stamp is missing, the current date	is used.

     arpsnmp can also be used to merge files.  If the same ethernet/ip address
     pair occurs in more than one file,	the timestamp from the last seen is
     saved.

     The -C flag uses compact padded ethernet addresses	in arp.dat, e.g.
     0:8:e1:1:2:d6.

     The -d flag is used enable	debugging. This	also inhibits mailing the re-
     ports.  Instead, they are sent to stderr.

     The -D flag is used to specify the	working	directory. This	defaults to
     /usr/local/arpwatch.

     The -f flag is used to set	the ethernet/ip	address	database filename.
     The default is arp.dat.

     Note that an empty	file must be created before the	first time you run

     The -q flag suppresses reports being logged or printed to stderr.

     The -s flag suppresses reports sent by email.

     The -w flag is used to specify the	target address for email reports. The
     default is	root.

     The -W flag is used specifies the from address for	email reports. The de-
     fault is root.

     The -Z flag (default) uses	zero padded ethernet addresses in arp.dat,
     e.g. 00:08:e1:01:02:d6.

BUGS
     Please send bug reports to	<arpwatch@ee.lbl.gov>.

     It	doesn't	make any sense to feed arpsnmp the arp.dat file.

     Attempts are made to suppress DECnet flip flops but they aren't always
     successful.
