UDP PACKET GENERATOR

UDP Packet Generator is an old file made a few years ago, to send packets to specific destinationIP addresse with random source addresses.

Note : It only works on Unix based systems.

Used against some cisco IP phones, it is able to perform a DOS attack.

How to

• Do not forget to change the IP address on line 28 and 31 :

udp("xxx.xxx.xxx.xxx"); //replace with IP

• To compile :

$ gcc UDPacketGenerator.c -o udpPacketGenerator

• To run :

$ ./udpPacketGenerator

This line defines the number of packets to send

 #define N_LOOP 10

Change 10 by 1000 if you need to send a 1000 packets

Errors

If you face the following error:

DPacketGenerator.c:48:2: warning: this decimal constant is unsigned only in ISO C90 [enabled by default]
  unsigned long ip_src = hasard(4294967295/2,4294967295);

Simply replace line 53 with this one :

unsigned long ip_src = hasard(4294967295LL/2,4294967295LL);
