ARPSNMP(8)ARPSNMP(8)NAMEarpsnmp - keep track of ethernet/ip address pairings
SYNOPSISarpsnmp [ -d ] [ -f datafile ] [ -m email ] file [ ... ]
DESCRIPTION
Arpsnmp keeps track for ethernet/ip address pairings. It syslogs activ‐
ity and reports certain changes via email. Arpsnmp reads information
from a file (usually generated by snmpwalk(8)).
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.
The -m flag specifies the address that will receive the emails. The
default is root.
Note that an empty arp.dat file must be created before the first time
you run arpsnmp.
