NAME

Net::Frame::SLL - Linux cooked capture layer object

SYNOPSIS

use Net::Frame::SLL qw(:consts);

# Build a layer
my $layer = Net::Frame::SLL->new(
   packetType    => NF_SLL_PACKET_TYPE_SENT_BY_US,
   addressType   => NF_SLL_ADDRESS_TYPE_512,
   addressLength => 0,
   source        => 0,
   protocol      => NF_SLL_PROTOCOL_IPv4,
);
$layer->pack;

print 'RAW: '.$layer->dump."\n";

# Read a raw layer
my $layer = Net::Frame::SLL->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 Linux cooked capture layer.

See also Net::Frame::Layer for other attributes and methods.

ATTRIBUTES

packetType

Stores the packet type (unicast to us, sent by us ...).

addressType

The address type.

addressLength

The length of the previously specified address.

source

Source address.

protocol

Encapsulated protocol.

The following are inherited attributes. See Net::Frame::Layer for more information.

raw

payload

nextLayer

METHODS

new

new (hash)

Object constructor. You can pass attributes that will overwrite default ones. See SYNOPSIS for default values.

The following are inherited methods. Some of them may be overriden in this layer, and some others may not be meaningful in this layer. See Net::Frame::Layer for more information.
