Port Scanner Command for iOS and iPhone

What is Port Scanning?

Port scanning is the process of probing a server or host for open TCP ports. Each open port represents a running service — for example, port 80 (HTTP), port 443 (HTTPS), port 22 (SSH), or port 3306 (MySQL). Identifying open ports is a fundamental step in network security auditing.

How to Use PortScan on iOS

In the CMD terminal:

> portscan 192.168.1.1 1 1024

This scans ports 1 through 1024 on the target host. The tool reports which ports are open and responding.

Why Scan Ports from Your iPhone?

Network administrators often need to verify that firewall rules are correctly applied, or check whether a service is exposed to the internet. With CMD, you can perform these checks instantly from your pocket — during a site visit, from a client's office, or while monitoring infrastructure remotely.

Security Best Practices

• Only scan hosts you own or have permission to test
• Use port scanning to verify firewall configurations
• Regularly audit exposed services on production servers
• Close unnecessary open ports to reduce attack surface
