FAQ

Frequently asked questions

Common questions about the Port Checker.

What ports should I check?

Common ports: 22 (SSH), 80 (HTTP), 443 (HTTPS), 3306 (MySQL), 5432 (PostgreSQL), 6379 (Redis), 8080 (HTTP Alt). Only leave ports open that you need.

Why is a port showing as closed?

A port may be closed because the service is not running, a firewall is blocking it, or the server is down. Check your firewall rules and service status.

Is port scanning legal?

Port scanning your own servers is legal. Scanning servers you do not own may violate terms of service or laws in some jurisdictions. Only scan hosts you control.
