How do I kill the process using port 1080?

On macOS & Linux, run: "sudo systemctl stop danted || sudo killall danted". On Windows PowerShell (as Admin), run: "Stop-Process -Name danted -Force -ErrorAction SilentlyContinue".

Why am I getting "port 1080 already in use" (EADDRINUSE)?

This occurs when another background instance of danted, shadowsocks, microsocks or a zombie process is already bound to port 1080. Use the kill commands above to free the port immediately.

Security

Risk: High

Port 1080 — SOCKS Proxy Protocol (SOCKS4 / SOCKS5)

Q: Is Port 1080 safe to expose to the public internet?

Risk level is High. Open, unauthenticated SOCKS proxies on port 1080 are quickly discovered by botnets and abused as spam relays or attack launchpads.

Port 1080 is the designated default port for SOCKS proxy servers (such as Dante or Shadowsocks), routing arbitrary TCP/UDP client traffic through an intermediary proxy.
