Transparently Proxy All Traffic Through TOR

In this post we will learn how to proxy all the network's traffic (TCP and UDP) transparently through TOR with least difficulty.

Requirements:

• Linux OS (tested on alpine and ubuntu)

• iptables (Linux firewall)

• RedSocks

What is RedSocks?

Reference: https://github.com/darkk/redsocks

Redsocks is the tool that allows you to proxify(redirect) network traffic through a SOCKS4, SOCKS5 or HTTPs proxy server. It works on the lowest level, the kernel level (iptables). The other possible way is to use application level proxy, when the proxy client is implemented in the same language as an application is written in. Redsocks operates on the lowest system level, that’s why all running application don’t even have an idea that network traffic is sent through a proxy server, as a result it is called a transparent proxy redirector.

System’s Architecture and Setup for TCP Connections

So this is the big image, almost every tcp packet will be redirected to port 12345 which redsocks service listens for incoming packets; after that, redsocks will redirect the received traffic to another ip and port in socks protocol format.

Also have in mind that for iptables in docker, you have to use docker run --privileged flag

Easiest Way to Run Multimedia (GUI) Applications Inside Docker

In this post I will show you not only how to run any multimedia application inside docker, but also in efficient and easy way.

Requirements:

• Linux OS and Docker (tested on ubuntu)

• X or Wayland (Linux Display Servers)

  • Ensure that the packages for an X or Wayland server are present on the Docker host. Please consult your distribution's documentation if you're not sure what to install. A display server does not need to be running ahead of time.

• X11docker

  • x11docker allows Docker-based applications to utilize X and/or Wayland on the host. Please follow the x11docker installation instructions and ensure that you have a working setup on the Docker host.

What is X11Docker?

Reference: https://github.com/mviereck/x11docker/

x11docker allows to run graphical applications (or entire desktops) in Docker Linux containers.

• Docker allows to run applications in an isolated container environment. Containers need much less resources than virtual machines for similar tasks.

• Docker does not provide a display server that would allow to run applications with a graphical user interface.

• x11docker fills the gap. It runs an X display server on the host system and provides it to Docker containers.

• Additionally x11docker does some security setup to enhance container isolation and to avoid X security leaks. This allows a sandbox environment that fairly well protects the host system from possibly malicious or buggy software.
