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(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.
(Debian) The -s flag is used to specify the path to the sendmail program. Any program that takes the option -odi and then text from stdin can be substituted. This is useful for redirecting reports to log files instead of mail.
(Debian) The -m option is used to specify the e-mail address to which reports will be sent. By default, reports are sent to root on the local machine.
Note that an empty arp.dat file must be created before the first time you run arpsnmp.
(See the arpwatch(1) man page for details on the report messages generated by arpsnmp(1).)
