Universal Bypass Tool

Network stack research tool. TCP tunnel with pluggable transports.

Client (SOCKS5) --> Transport (Yandex Docs WS) --> Exit Node --> Internet

What it does

Sends TCP packets through Yandex Docs cursor messages. Client side runs a SOCKS5 proxy, exit node decapsulates and forwards to real internet.

Build

go mod tidy
go build -o openflux .

Usage

Exit node (needs root):

sudo iptables -A OUTPUT -p tcp --tcp-flags RST RST -j DROP
sudo ./openflux --exit-node --url "YOUR_YANDEX_DOC_URL" --debug

Client:

./openflux --client --url "YOUR_YANDEX_DOC_URL" --socks5 :1080 --debug

Then point your browser to SOCKS5 proxy at localhost:1080.

Flags

Flag	Default	Description
--client		Run as client
--exit-node		Run as exit node
--url	https://localhost	Document URL
--socks5	:1080	SOCKS5 listen addr
--debug	false	Verbose logging
--transport	yandex	Transport backend

Adding new transports

Implement the Transport interface from transport/transport.go, add your package, register in main.go switch.
