NAME

       arpsnmp - keep track of ethernet/ip address pairings

SYNOPSIS

       arpsnmp [ -d ]
               [ -f datafile ]
               [ -s sendmail_path ]
               [ -m addr ]
               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(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.
