Hey Guyz & Galz,
Ch3rn0byl, Grey-Matter and I were having a blast with one of the vulnhub VM's called knockknock, this VM required some portknocking
to be done and how / why it wasnt working as I expected it to was really, really annoying me..
So after we (ok, well ch3rn) figured out how to get the port knocking to work consistently I still couldn't let it go and had to script
something to get it off my chest, outta my head
Enter knocker.sh !
Help info & options (-h switch);
Some examples (-x switch);
Version info (-v switch);
Some feedback if you don't give sufficient / correct input;[size=78%]knocker.sh in action on 3 ports;[/size]
Knocking on the same 3 ports, but repeating the process 3x ;
Knocking on all possible sequences of the given ports;
And the one it was actually kinda made for.. knocking on all ports in all sequences after getting port info from NetCat banner grabbing on port 1337;
Useful ? Well, probably only of you are doing that particular VM and have forgotten how to do the knocking sequence... lol
But in any case fun to make and informative if you are new to port knocking.
Any feedback appreciated especially if you encounter bugs or have improvement suggestions !
