NAME
Net::Packet::ARP - Address Resolution Protocol layer 3 objectSYNOPSIS
use Net::Packet::Consts qw(:arp); require Net::Packet::ARP; # 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.
