.TH ARPFETCH 8
.SH NAME
arpfetch \- obtain ethernet/ip address pairings via snmp
.SH SYNOPSIS
.na
arpfetch
.I host
.I cname
.SH "DESCRIPTION"
.B 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
.BR snmpwalk(1) .
Mostly, this program is an agent that
is used to get data for
.BR arpsnmp(8) .
This fetching of address mappings can be further automated by use of
.BR bihourly(8) .
.LP
Both command arguments must be present for proper operation.
The
.IR host
argument is the hostname of the network entity being queried and the
.IR cname
argument is the SNMP community name of the network entity.
.LP
The information is presented on
.IR stdout
in a format compatible with
.BR arpsnmp(8)
and
.BR arpwatch(8) .
.LP
Further information about SNMP can be found in
.BR snmpcmd(1)
and
.BR variables(5) .
