  1. Have you guys hear of this port knocker software?
  2.  
  3. http://www.zeroflux.org/projects/knock/
  4.  
  5. I listens at link-layer for a specific sequence of ports (open or not) that can be knocked with TCP of UDP packets. And if the sequence matches your config it will do something.. Like open SSH port or run something on the machine.

  7. Best part is that it runs on most of the platforms (shockingly enough even on windows native)
  8.  
  9. Pretty awesome idea. You can have a script run a sequence of port knock before each SSH and the problem with custom ports and brute force is eliminated.

  11. Thanks for the great show guys.
