NAME

ARP - Perl extension for creating ARP packets

SYNOPSIS

  use Net::ARP;
  Net::ARP::send_packet('lo',                 # Device
                        '127.0.0.1',          # Source IP
	                '127.0.0.1',          # Destination IP
		        'aa:bb:cc:aa:bb:cc',  # Source MAC
	                'aa:bb:cc:aa:bb:cc',  # Destinaton MAC
	                'reply');             # ARP operation

Net::ARP::get_mac("eth0",$mac); print "$mac\n";

Net::ARP::arp_lookup($dev,"192.168.1.1",$mac); print "192.168.1.1 has got mac $mac\n";

DESCRIPTION

This module can be used to create and send ARP packets and to get the mac address of an ethernet interface or ip address.

send_packet()

  Net::ARP::send_packet('lo',                 # Device
                        '127.0.0.1',          # Source IP
	                '127.0.0.1',          # Destination IP
		        'aa:bb:cc:aa:bb:cc',  # Source MAC
	                'aa:bb:cc:aa:bb:cc',  # Destinaton MAC
	                'reply');             # ARP operation

  I think this is self documentating.
  ARP operation can be one of the following values:
  request, reply, revrequest, revreply, invrequest, invreply.
  The default ARP operation is reply.

get_mac()

Net::ARP::get_mac("eth0",$mac);

This gets the MAC address of the eth0 interface and stores 
it in the variable $mac. The return value is "unknown" if
the mac cannot be looked up.

arp_lookup()

Net::ARP::arp_lookup($dev,"192.168.1.1",$mac);

This looks up the MAC address for the ip address 192.168.1.1
and stores it in the variable $mac. The return value is 
"unknown" if the mac cannot be looked up.
