Scanning: Port knocking

Hi everyone,

I've just been working through the port knocking lab and all has been going well. However, the final knock (31337, 32337, 33337) doesnt seem to be opening up the ssh connection for me.  If anyone has any tips or suggestions they would be much appreciated as I'm absolutely certain ive knocked correctly and also tried to connect via ssh correctly.

Regards,

Andy

    Hey Andy, 

    Jay Noonan here. Just ran the lab before getting off its pretty straight forward and sounds like you got the last one. Its pretty much same same.

    knock TARGET-IP 31337 32337 33337
    ssh james@TARGET-IP

    The password for ssh is in the question. This should get you onto the machine and you wont be looking far for the token.

    Hi Jay!

    Many thanks! I'll run it again, I'm pretty certain I ran it exactly as you stated, however it was fairly late on so there's every chance I was simply brain-dead! 

    Thanks again!

    Andy.
