Re: [gentoo-user] Re: [WAY OT] wanna learn networking internals

[Francisco Ares]

Thanks, James.

I already know C and a bit of C++, and that's why I want to understand
deeply about networking protocols, there are some tricks that I see some
device's closed source SDKs doing that I would like to reproduce. And
probably - if they worth it - publish as open source, of course.

Best Regards,
Francisco
