A pipe-like SOCKS5 tunnel system.

Pipesocks is aimed at going through firewalls which are built by national force, with strong encryption and relay servers to avoid content censorship.

This software consists of 3 parts: pump, pipe, and tap. Pump is the server outside the firewall to provide Internet data for tap. Pipe is a relay server which unconditionally transfers data through pump and tap. Tap is a client running in local with SOCKS5 interface for native clients and connects to pump or pipe. Tap can also provide PAC script if you request it using HTTP GET. You can also get GFWList PAC script if you include "gfwlist" in the HTTP packet.

A pipe or a tap is valid only if:

1. It is directly connected to the pump.

Or

2. It is connected to a valid pipe.

Pre-compiled files for various platforms can be found here.

Download & install Qt Creator with Qt (above 5.7) and libsodium. Open the project with Qt Creator, set include path and link path and compile.

Since most Ubuntu servers don't hold a GUI, here is the way to deploy pipesocks in them.

Type these commands in your terminal:

sudo apt-get -y install git make build-essential qt5-default qt5-qmake libtool autoconf automake
cd /tmp/
git clone https://github.com/pipesocks/pipesocks.git
cd pipesocks/
git checkout stable
git submodule update --init --recursive
cd libsodium/
./autogen.sh
./configure
make && sudo make install
sudo cp /usr/local/lib/libsodium.so.18 /usr/lib/
cd ../pipesocks/
qmake server.pipesocks.pro && make
sudo cp pipesocks /usr/bin/

And you'll be able to run pipesocks.

To install libsodium, you can type these commands in your terminal:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null
brew install libsodium

If you don't want to compile libsodium yourself, you can download the precompiled library right here.

You can start pipesocks GUI by double-clicking the program icon or running it in the terminal, providing no arguments.

Following are the commands to be typed in the terminal.

./pipesocks pump [-p Local Port] [-k Password]
./pipesocks pipe <-H Remote Host> [-P Remote Port] [-p Local Port]
./pipesocks tap <-H Remote Host> [-P Remote Port] [-p Local Port] [-k Password]
