That base64 thing was so good :D. Thanks for making such great videos.

[@ilyboc]

But actual port knocking using knockd or something wouldn't tell you if the port is open or not plus the port sequence can be generated too

[@realNAKAMI]

why is python 2 usage still so common...

[@bugr33d0_hunter8]

nakami @ because of all the functions still supported like the. Socket functions for example. For some reason in python 3 they went and changed everything around. You could always port the libraries into python 3, but I bet it would be a pain to figure out.

[@lordtony8276]

because print doesn't required parentheses.

[@dayisnow]

@@lordtony8276 Lol your comment gave me a solid laugh. Nice joke haha.

[@kallikantzaros]

you bastard

[@bugr33d0_hunter8]

Dude that was awesome. I love the python editor, its so colorful, and the way you move so smoothly through it. I'm starting to read black hat python for pentesting. Do you think that will help me understand better how to write those kind of scripts? I'm obviously going to finish all the overthewire challenges. I wonder though if there are just strictly python challenges alone? And if so could you maybe name one or two beginner type challenges. Thanks. Again this was a great video.

[@vamsikolati]

this is some elite stuff

[@_JohnHammond]

Thank you! Will do!

[@dxlsvy]

[@TheL96]

great! I will refer anybody that wants to learn python in 20 mins...lol

[@mauldoto]

why scanning process so quickly on that ranges? :v

[@TheBroadwood]

So cool

[@tesloveley]

i want to see this kind of video on Windows

[@mauriciomatias6261]

Which is the page?

[@KaleshwarVhKaleshwarVh]

This was good.

[@Vagelis_Prokopiou]

Exquisite stuff!

[@jerrybailie]

that base64 copy/paste was bananas !!!

[@_JohnHammond]

Ha! Thanks so much for watching!

[@realgabreal]

awesome!

[@JasonSmith-fu6oi]

yeah good luck getting into a real server with knockd configured to the MAX with no other ports running on that box. you're NEVER going to guess the sequence plus it can be configured with two other settings that you overlooked because you want to demonstrate how you could break knockd: that is, a timeout of the sequence. good luck with that permutation loop. i can set my seq timeout to 1 second. if you dont knock within 1 second, you're done. that loop will take several minutes to complete only to disappoint you. and the second setting is basically TCPFlags that can be set. if you dont know this FLAG, you aint gettin a glimpse of my door!

[@fsacer]

it's quicker to just base64 -w 0 x

[@dayisnow]

If they're both one-liners, then I don't see how this saves much time. Maybe 1-2 seconds? Cool hint regardless though, gonna try it out!
