Cổng:9050— Tor SOCKS Proxy

Port 9050 sits in the Security Tools category. This page lists the registered purpose and the software commonly associated with it; to see what is actually listening on a specific machine, check the process with ss/netstat.

The registered protocol on this page is TCP. The same number behaves independently on each protocol: TCP may be listening while UDP is idle, so check them separately.

On Linux: sudo ss -tlnp 'sport = :9050' for an exact port match. On macOS: sudo lsof -nP -iTCP:9050 -sTCP:LISTEN. On Windows PowerShell: Get-NetTCPConnection -LocalPort 9050 -State Listen. A listener counts as confirmed only when you can see the bind address and process name; without root/admin you will not see other users' processes.

A port number has no inherent security — it depends on whether the listening service is correctly configured and whether it needs exposure at all. Keep loopback/internal-only services firewalled; where public access is required, pair it with source restrictions, VPN or authentication.
