NAME

Net::Packet::ARP - Interface for decoding ARP packets.

SYNOPSIS

use Net::Packet::ARP :short;

my $frame = Buf.new([...]);
my $arp = ARP.decode($frame);

say sprintf '%s(%s) -> %s(%s): %s',
    $arp.src_hw_addr.Str, $arp.src_proto_addr.Str,
    $arp.dst_hw_addr.Str, $arp.dst_proto_addr.Str,
    $arp.operation;

Prints '66:77:88:99:AA:BB(102.119.136.153) -> 00:11:22:33:44:55(0.17.34.51): Request'

EXPORTS

Net::Packet::ARP
Net::Packet::ARP::HardwareType
Net::Packet::ARP::Operation

:short trait adds exports:

constant ARP               ::= Net::Packet::ARP
# Implies:
         ARP::HardwareType ::= Net::Packet::ARP::HardwareType
         ARP::Operation    ::= Net::Packet::ARP::Operation

DESCRIPTION

Net::Packet::ARP takes a byte buffer and returns a corresponding packet object. The byte buffer can be of the builtin Buf type or the C_Buf type of Net::Pcap.

enum Net::Packet::ARP::HardwareType

Type to describe the hardware type field of an ARP packet.

enum Net::Packet::ARP::Operation

Type to describe the operation field of an ARP packet.

class Net::Packet::ARP

is Net::Packet::Base

Attributes

 $.hw_type         is rw is Net::Packet::ARP::HardwareType
  Hardware address type field

$.proto_type      is rw is Net::Packet::EtherType
  Protocol address type field

$.hw_len          is rw is Int
  Hardware address length field

$.proto_len       is rw is Int
  Protocol address length field

$.operation       is rw is Net::Packet::ARP::Operation
  Operation field

$.src_hw_addr     is rw
$.dst_hw_addr     is rw
$.src_proto_addr  is rw
$.dst_proto_addr  is rw
  Sender/Receiver hardware/protocol address fields. Typed with the type
  of address (eg. Net::Packet::IPv4, Net::Packet::MAC_addr).

Methods

.decode($frame, Net::Packet::Base $parent?) returns Net::Packet::ARP
  Returns the ARP packet corresponding to $frame.

.encode()
  Writes to packet to the $.frame buffer.
