Linux NetFilter, IP Tables and Conntrack Diagrams

IPTABLES TABLES and CHAINS

IPTables has the following 4 built-in tables.

1) Filter Table

Filter is default table for iptables. So, if you don’t define you own table, you’ll be using filter table. Iptables’s filter table has the following built-in chains.

Distribution Detection

I am working on adding support for building and distributing (via PyPI) Python Wheels with C Extensions to the Python wheel and pip packages. The discussion on Distutils-SIG continues, but I believe it is fairly certain that some effort to correctly identify Linux distributions will need to be made. I've begun efforts to add this support to wheel.

How you can help

If you have a Linux distribution or version of a listed distribution not in this gist, or one of the ones I have not directly verified, I could use the following:

• The contents of /etc/os-release, if it exists

FauxFaux

Ubuntu encourage upgrading between releases by running a command, instead of by manually editing sources and getting on with it. This tool's name is do-release-upgrade, and I believe it should just be doing:

sed -i 's/wily/xenial/g' /etc/apt/sources.list /etc/apt/sources.list.d/*

This command does not explain what it wants to do, or why it is doing anything. It has, in the past:

• Disabled repos I was using, and hence broken the software in them.

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft
