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.

Cross-Compiling SDL2 Programs for Windows from Linux using MinGW-w64

I'll explain how to create programs that run on Windows (.exe files) from a Linux machine. I'll explain how to compile C and C++, and how to make 32- and 64-bit programs. I'll also explain how to use third-party libraries (we'll use SDL2 here), and how to distribute the programs. We'll use the MinGW-w64 toolchain to accomplish this.

Note: MinGW-w64 is a fork of its predecessor, MinGW. They are different. If you install MinGW-w64 in a different way than shown in this document, make sure you have MinGW-w64, not just MinGW!

Installing and Using a Cross-Compiler

install openjdk

sudo add-apt-repository ppa:openjdk-r/ppa

sudo apt-get update

sudo apt-get install openjdk-8-jdk

	* Web proxy detector detector script by OlyB
	* Last updated: 2024-10-30
	* Currently supports Securly and GoGuardian detection methods
	* Paste into browser console to use :)
	*
	* Securly detects using various query selectors and element content,
	* While GoGuardian primarly uses the page's visible text content as well as script/img source attributes, which it checks against a list of terms.
	* When detected, the script will log the matching selectors and/or terms.
