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.
