NAME

Net::Packet::DescL4 - object for a transport layer (layer 4) descriptor

SYNOPSIS

   require Net::Packet::DescL4;

   # Get NP_DESC_* constants
   use Net::Packet::Consts qw(:desc :layer);

   # Usually, you use it to send TCP and UDP frames over IPv4
   my $d4 = Net::Packet::DescL4->new(
      target   => '192.168.0.1',
      protocol => NP_DESC_IPPROTO_TCP,
      family   => NP_LAYER_IPv4,
   );

   $d4->send($rawStringToNetwork);

DESCRIPTION

See also Net::Packet::Desc for other attributes and methods.

ATTRIBUTES

target: IPv4 address of the target host. You must set it to be able to send frames.
protocol: Transport protocol to use, see NP_DESC_IPPROTO_* constants in Net::Packet::Desc. You must set it to be able to send frames.
family: The family address of target attribute. It is either NP_LAYER_IPv4 or NP_LAYER_IPv6.

METHODS

new

Create the object, using default $Env object values for dev, ip, ip6 and mac (see Net::Packet::Env). When the object is created, the $Env global object has its desc attributes set to it. You can avoid this behaviour by setting noDescAutoSet in $Env object (see Net::Packet::Env).
