a tiny TCP over ICMP tunnel in pure python
From the README.md
, it looks like you want to rework the thread & socket management. The Python community seems to have shifted to the asynchronous IO paradigm. It could probably give cleaner code & better performance.
For a small project build from scratch that doesn't need to leverage other libraries I would recommend curio (much easier to grasp and has less pitfalls than asyncio or there is trio which I never used but is inspired by curio's design principles).
I'll let you look at the examples to see how much the a client/server implementation may be cleaner.
Also, it seems you require root permissions so why don't you bring up a real tunnel and handle more than TCP by creating TUN or TAP devices (by opening /dev/net/tun
on Linux)? It's easy to do with Python, if a bit obscur (since you'll have to define a couple of things yourself instead of relying on header files). The downside being you'll probably need to assign IP addresses on both sides.
This part of code, basicly the struct parts and not functioning correctly, if you help me with that i will share with you also a private project of mine, i mannged to use your code to make reverse Socks5 proxy server using ICMP.
BUT i need to work in python3 since my code is in python3, im not able to figure out the logic of what you did there i port it my self, please help :)
Thanks in advance
