-Sending ARP, ICMP Packet (libtins Examples)-

[ARP]

#include <unistd.h>
 
int main()
{

    //Target IP
 
    Tins::NetworkInterface iface = Tins::NetworkInterface::default_interface();
    Tins::NetworkInterface::Info info = iface.addresses();
    //Get addresses from network interface
 
    Tins::EthernetII eth = Tins::EthernetII("ff:ff:ff:ff:ff:ff", info.hw_addr);
    //Set L2 Ethernet Packet as Broadcast Packet
 
    Tins::ARP testARP = Tins::ARP(target, info.ip_addr, "00:00:00:00:00:00", info.hw_addr);
    //Setup L3 ARP Packet (target_ip, sender_ip, target_hw, sender_hw)
 
    testARP.opcode(Tins::ARP::Flags::REQUEST);
    //Set ARP flag as Request
 
    eth /= testARP;
    //Build-up ARP Protocol on Ethernet
 
    printf("Send!\n");
    sender.send(eth, iface);
    //Send Packet
