Port Scanner

About Port Scanning:

Port scanning is used to check the open status of specific ports on the target host, helping you understand the services exposed by the server. 20 ports can be entered, sending 5 per batch to the interface, automatically querying in batches.

• Open: Port is accessible, the corresponding service is listening.
• Closed: Port is inaccessible, the service is not running or blocked by a firewall.
• Legal use: Only scan hosts you have permission to test.
