arpfetch - obtain ethernet/ip address pairings via snmp
SYNOPSIS
arpfetch
hostcname
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).
