wssocks

socks5 over websocket.

wssocks can proxy TCP and UDP(not implemented currently) connections via socks5. But the socks5 data is wrapped in websockets and then sent to server.

Features

Transporte data through firewalls
In some network environment, due to the restricts of firewalls, only http(s)/websocket is allowed. wssocks is mainly useful for passing through firewalls. We can access the inner netwrok (such as ssh) behind the firewalls via socks protocol wrapped in websockets.
High performance
wssocks only create one TCP connection (websocket) per client to handle multiple socks5 connections, which achieves much higher performance.
Easy to use
No configures, no dependences, just a single executable including client and server.

Install

go get -u github.com/genshen/wssocks

You can also download it from release page.

Usage

server side

wssocks server --addr :1088

client side

wssocks client --addr :1080 --remote ws://example.com:1088
# using ssh to connect to example.com which may be behind firewalls.
ssh -o ProxyCommand='nc -x 127.0.0.1:1080 %h %p' user@example.com

And set your socks5 server address as :1080 in your socks5 client (such as proxifier or proxy setting in mac's network preferences) if you need to use socks5 proxy in more situations, not only ssh in terminal.

enable http and https proxy

You can also enable http and https proxy by --http option(in client side) if http(s) proxy in server side is enabled:

# client siede
wssocks client --addr :1080 --remote ws://example.com:1088 --http

The http proxy listen address is specified by --http-addr in client side (default value is :1086), and https proxy listen address is the same as socks5 proxy listen address(specified by --addr option).

Then you can set server address of http and https proxy as :1080 in your http(s) proxy client (e.g. mac's network preferences).

note: http(s) proxy is enabled by default in server side, you can disable it in server side by wssocks server --addr :1088 --http=false .
