Net::Write::Layer3 - object for a network layer (layer 3) descriptor
use Net::Write::Layer qw(:constants); use Net::Write::Layer3; my $desc = Net::Write::Layer3->new( dst => '192.168.0.1', protocol => NW_IPPROTO_RAW, family => NW_AF_INET, ); $desc->open; $desc->send('G'x666); $desc->close;
This is the class for creating a layer 3 descriptor.
The target IPv4 or IPv6 address we will send frames to.
Address family, see Net::Write::Layer CONSTANTS section.
Transport layer protocol to use, see Net::Write::Layer CONSTANTS section.
Object constructor. You MUST pass a valid dst attribute. Default values:
Returns undef on error.
Open the interface. Returns undef on error.
Send raw data to the network.
Close the descriptor.
Sending IPv6 frames does not work under BSD systems. They can't do IP_HDRINCL for IPv6. For now, only Linux supports this (at least, with a 2.6.x kernel).
Does not work at all under Win32 systems. They can't send frames at layer 3 (or I don't know how to do that).
