NAME ^

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

SYNOPSIS ^

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

   # Build a layer
   my $layer = Net::Frame::Layer::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::Layer::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 overridden in this layer, and some others may not be meaningful in this layer. See Net::Frame::Layer for more information.
