"""Find an OPEN port to your SOCKS proxy from the hosting server.

Your SOCKS provider offers 1080, 9100-9200, and 6000-6010. The host blocks 1080
(confirmed). This scans ALL those ports to the SOCKS IP and reports which are reachable,
so you can pick an open one and ask the SOCKS provider to route on it.

Usage (on the server):
    python scan_socks_ports.py
    # or override the IP:
    SOCKS_HOST=169.197.93.90 python scan_socks_ports.py
