Net::Packet::ARP(3)   User Contributed Perl Documentation  Net::Packet::ARP(3)

NAME
       Net::Packet::ARP	- Address Resolution Protocol layer 3 object

SYNOPSIS
	  use Net::Packet::Consts qw(:arp);
	  require Net::Packet::ARP;

	  #A Build a layer
	  my $layer = Net::Packet::ARP->new(
	     dstIp => "192.168.0.1",
	  );
	  $layer->pack;

	  print	'RAW: '.unpack('H*', $layer->raw)."\n";

	  # Read a raw layer
	  my $layer = Net::Packet::ARP->new(raw	=> $raw);

	  print	$layer->print."\n";
	  print	'PAYLOAD: '.unpack('H*', $layer->payload)."\n"
	     if	$layer->payload;

DESCRIPTION
       This modules implements the encoding and	decoding of the	ARP layer.

       RFC: ftp://ftp.rfc-editor.org/in-notes/rfc826.txt

       See also	Net::Packet::Layer and Net::Packet::Layer3 for other
       attributes and methods.

ATTRIBUTES
       hType
       pType
	   Hardware and	protocol address types.

       hSize
       pSize
	   Hardware and	protocol address sizes in bytes.

       opCode
	   The operation code number to	perform.

       src
       dst Source and destination hardware addresses.

       srcIp
       dstIp
	   Source and destination IP addresses.

METHODS
       new Object constructor. You can pass attributes that will overwrite
	   default ones. Default values:

	   hType:  NP_ARP_HTYPE_ETH

	   pType:  NP_ARP_PTYPE_IPv4

	   hSize:  NP_ARP_HSIZE_ETH

	   pSize:  NP_ARP_PSIZE_IPv4

	   opCode: NP_ARP_OPCODE_REQUEST

	   src:	   $Env->mac

	   dst:	   NP_ARP_ADDR_BROADCAST

	   srcIp:  $Env->ip

	   dstIp:  127.0.0.1

       pack
	   Packs all attributes	into a raw format, in order to inject to
	   network. Returns 1 on success, undef	otherwise.

       unpack
	   Unpacks raw data from network and stores attributes into the
	   object. Returns 1 on	success, undef otherwise.

       recv
	   Will	search for a matching replies in framesSorted or frames	from a
	   Net::Packet::Dump object.

       isRequest
       isReply
	   Returns 1 if	the opCode attribute is	of specified type.

CONSTANTS
       Load them: use Net::Packet::Consts qw(:arp);

       NP_ARP_HTYPE_ETH
       NP_ARP_PTYPE_IPv4
	   Hardware and	protocol address types.

       NP_ARP_HSIZE_ETH
       NP_ARP_PSIZE_IPv4
	   Hardware and	protocol address sizes.

       NP_ARP_OPCODE_REQUEST
       NP_ARP_OPCODE_REPLY
	   Operation code numbers.

       NP_ARP_ADDR_BROADCAST
	   Broadcast address for src or	dst attributes.
