Simple socks5 proxy server written in python.

PySocks5Server

Simple socks5 proxy server written in python.

Installation

Requirements:

• Python 3.10+

pip install pysocks5server

Usage

Usage: python -m socks5server [-h] [--host HOST] [--port PORT] [--no-auth] [--users [USERS ...]]

options:
  -h, --help           show this help message and exit
  --host HOST
  --port PORT
  --no-auth            Allow connections without authentication.
  --users [USERS ...]  List of users. Example: "--users user1:password1 user2:password2"

TODO

• TCP/IP port binding
• UDP port association
• Socks4/socks4a support?

Code examples

Run server without authentication

from asyncio import get_event_loop
from socks5server import SocksServer

server = SocksServer("0.0.0.0", 1080, True)

if __name__ == '__main__':
    get_event_loop().run_until_complete(server.serve())

Run server with callbacks

from asyncio import get_event_loop
from socks5server import SocksServer, Socks5Client, DataDirection

server = SocksServer("0.0.0.0", 1080, True)

@server.on_client_connected
async def client_connected(client: Socks5Client):
    print(f"Client connected: {client}")
    
    
@server.on_client_disconnected
async def client_disconnected(client: Socks5Client):
    print(f"Client disconnected: {client}")
    
    
@server.on_data
async def data_received(client: Socks5Client, direction: DataDirection, data: bytes):
    print(f"{direction} | {data}")

    
if __name__ == '__main__':
    get_event_loop().run_until_complete(server.serve())

Run server with password authentication

from asyncio import get_event_loop
from socks5server import SocksServer, PasswordAuthentication

server = SocksServer("0.0.0.0", 1080)
users = {"test_login1": "test_password1", "login": "password"}
server.register_authentication(0x02, PasswordAuthentication(users))  # 0x02 is password authentication type

if __name__ == '__main__':
    get_event_loop().run_until_complete(server.serve())

Run server with custom authentication

All Authentication methods

import asyncio
from asyncio import get_event_loop
from socks5server import SocksServer, AuthenticationBase


class ChallengeHandshakeAuthentication(AuthenticationBase):
    async def authenticate(self, reader: asyncio.StreamReader, writer: asyncio.StreamWriter) -> bool:
        ... # Implement authentication process
    
        return True


server = SocksServer("0.0.0.0", 1080)

# 0x03 is type of Challenge–Handshake Authentication Protocol
server.register_authentication(0x03, ChallengeHandshakeAuthentication())

if __name__ == '__main__':
    get_event_loop().run_until_complete(server.serve())
