A secure and fast proxy for protect your network traffic

Introdution

• xSocksd: Backend of xSocks, xTproxy, xForwarder
• xSocks: A socks5 server
• xTproxy: A Transparent Proxy
• xForwarder: Forward data to a specific server
• xTunnel: Like xForwarder, but standalone and specify target on server side

Features

• Transparent Proxy for all tcp traffic and udp packet
• Cross-platform, including PC (Linux, macOS, Windows), Mobile (Android) and Router (OpenWRT, Tomatoware)
• Parallelization

BUILD

Linux

make && sudo make install

OpenWRT

# At OpenWRT build root
git clone https://github.com/lparam/xSocks.git package/xSocks
make package/xSocks/openwrt/compile

Windows

# win32
make mingw32 HOST=i686-w64-mingw32
# win64
make mingw32 HOST=x86_64-w64-mingw32

Tomatoware

# Install Tomatoware on your router from: https://github.com/lancethepants/tomatoware
git clone https://github.com/lparam/xSocks.git
make STATIC=1

Usage

Server

xSocksd -k PASSWORD
xTunnel -m server -k PASSWORD -t TARGET:PORT

Multithreading:

xSocksd -k PASSWORD -c THREADS

Stop:

xSocksd --signal stop

Client

xSocks -s SERVER:PORT -k PASSWORD
xForwarder -s SERVER:PORT -k PASSWORD -d DESTINATION:PORT
xTunnel -m client -k PASSWORD -t TARGET:PORT

Transparent Proxy

Proxy all tcp traffic and udp packet transparently on gateway.

root@OpenWrt:~# opkg install iptables-mod-tproxy
