socks5 handshake fragmenter

socks5 client <--> socks5-fragmenter <--> socks5 server

socks5 protocol specifies a handshake that can be easily detected by censorship firewalls. ([0x05 0x01 0x00] for no-auth-required method).

socks5-fragmenter is a relayer that relays connections to a specified socks server.

Its job is to fragment the handshake into ([0x05 auth_methods_num] and [auth_methods...]) instead of sending the handshake as a whole message ([0x05 auth_methods_num auth_methods...]) then it starts relaying.

Build

go build .

Usage

usage: socks5-fragmenter [bind_addr:bind_port] server_addr:server_port

bind_addr:bind_port is :5555 by default.

ex: to provide 192.168.1.50:3456 as the socks server address:

./socks5-fragmenter 192.168.1.50:3456

2022/08/11 04:59:42 Serving on :5555
2022/08/11 04:59:42 the provided server address is 192.168.1.50:3456

Now the program is ready to accept socks5 client connections on :5555 and relays them to the specified socks5 server 192.168.1.50:3456
