NAME

       arpfetch - obtain ethernet/ip address pairings via snmp

SYNOPSIS

       arpfetch host cname

DESCRIPTION

       arpfetch gets pairings between ip addresses and the ethernet address of the corresponding network card.
       These pairings are retrieved from other network entities, like routers, by the SNMP protocol using
       snmpwalk(1).  Mostly, this program is an agent that is used to get data for arpsnmp(8).  This fetching of
       address mappings can be further automated by use of bihourly(8).

       Both command arguments must be present for proper operation.  The host argument is the hostname of the
       network entity being queried and the cname argument is the SNMP community name of the network entity.

       The information is presented on stdout in a format compatible with arpsnmp(8) and arpwatch(8).

       Further information about SNMP can be found in snmpcmd(1) and variables(5).
