Windows Port Knock Application

It seems to be becoming more popular to use port knocking applications these days. Port knocking is sending connection attempts to a device in a specific pattern to unlock a specific service.

An example would be to send 3 UDP connection attempts to a Mikrotik router all on different port numbers in a specific order. It will then add your IP address to a specific address list so you can winbox in.

I found an application out there for windows that does it, but it only did UDP…I wanted one that would do both. I also wanted the ability to send text with the UDP connections to do L7 matches on it.

So, I wrote my own:

There is no charge for awesomeness...or attractiveness.

Basically what you do is fill out the entries, IP address, description and at least one knock port.

Fill out protocol type, the port you want to knock on and if it is UDP, you can optionally add some text to send with the message!

Here’s the program compiled and ready to go : PortKnock.zip (6249)

Here’s the code:

BTW, I just threw this together and haven’t properly tested, so let me know how it goes 😛

    Hello Greg,

    I have been setting up port knocking on my Mikrotik router. My setup is such that the knocks strictly have to be received by the router from the source IP in the correct order, with no other packets on different ports in between. I tried to use your app to send two TCP knocks followed by two UDP knocks, and it turns out that udp knock #3 was systematically reaching the firewall before TCP knock #2 (the test was on my lan, not from the internet). When I switched to 4 TCP knocks instead, all was well.

    I realize that this may be due to the nature of network comms or TCP/UDP stacks, but I would maybe suggest that your program allow to introduce some custom delay between the knocks to prevent this problem.

    All the best, feel free to email me if you need more details.
    David

  2. David / Jan 6 2012

    … I see in the code that you have hardcoded delays of 300ms between the knocks. It seems that I have the problem only when mixing tcp and udp knocks. If they are all tcp or all udp, all is well. I’ll try to recompile your code with bigger delays.

  3. Greg / Jan 6 2012

    @David
    Thanks for the update. If upping the delays fixes your issues, let me know and I’ll up them here. I’ve yet to have issues thus far personally, but every machine is different.

    I could possibly add some custom delay fields, but I’m currently so busy that I don’t have time to adjust the program. Possibly in a couple of weeks…

    Thanks a lot for this program, it does exactly what I expected for 🙂

  5. mike pratt / May 27 2013

    Greg, I have used port knocking for some time, and just ran across your clever tool. I like the interface and the recording of multiple knock targets, each with unique settings.

    However, I almost always use URL addresses for remote routers, hosted at DynDns, mostly. It would be great if your tool could store URLs when new entries are added, the then resolve them when executed, and use the result as the IP address.

    Ever give any thought to that?

    Thanks,

  6. Greg / May 31 2013

    @Mike
    It didn’t even occur to me in the beginning, but it sure makes sense. BTW, I assume you tested it unsuccessfully with a URL? If it doesn’t already, it wouldn’t take much to make the adjustment.
