What is Port Checking?
Port checking is a method to determine if a specific TCP or UDP port on a remote server or device is open and accepting connections. This can be useful for troubleshooting network connectivity issues, verifying firewall configurations, or checking if specific services are running.
Common Use Cases
- Verifying if a web server is running (port 80/443)
- Checking if an email server is accessible (port 25/587)
- Testing database connectivity (MySQL, PostgreSQL)
- Troubleshooting remote access services (SSH, RDP)
- Validating firewall configurations
