What is a port scanner?
A port scanner tests which TCP ports on a server are open and accepting connections. It helps administrators and security professionals identify running services and potential vulnerabilities on any server or network device.
Is port scanning legal?
Port scanning is legal only on servers you own or have explicit written permission to test. Unauthorized scanning may violate the Computer Fraud and Abuse Act (CFAA) and similar laws in other countries. Always scan responsibly.
Which ports should I check?
Common ports: 80 (HTTP), 443 (HTTPS), 22 (SSH), 21 (FTP), 25 (SMTP), 3306 (MySQL), 5432 (PostgreSQL), 3389 (RDP), 6379 (Redis), 27017 (MongoDB). Use the Full scan preset to check all 65535 ports.
