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

NAME

       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.

REPORT MESSAGES

       (See the arpwatch(8) man page for details on the report messages generated by arpsnmp(8).)

FILES

       /usr/operator/arpwatch - default directory
       arp.dat - ethernet/ip address database
       ethercodes.dat - vendor ethernet block list
