arpsnmp - keep track of ethernet/ip address pairings
SYNOPSIS
arpsnmp [ -d ] [ -f datafile ] file [ ... ]
DESCRIPTION
Arpsnmp keeps track for ethernet/ip address pairings. It
syslogs activity and reports certain changes via email.
Arpsnmp reads information from a file (usually generated
by snmpwalk(1)).
The -d flag is used enable debugging. This also inhibits
mailing the reports. Instead, they are sent to stderr.
The -f flag is used to set the ethernet/ip address
database filename. The default is arp.dat.
Note that an empty arp.dat file must be created before the
first time you run arpsnmp.
