Nmap (Network Mapper) is a powerful network scanning tool used to discover hosts and services on a computer network. It can be used to identify which ports are open on a remote server, which can help diagnose access issues to services like a remote file server.
Port Scanning: Nmap can perform comprehensive port scans to determine which ports are open and what services are running on those ports.
Network Discovery: It provides detailed information about the host’s operating system, service versions, and network configuration.
Security Audits: Besides troubleshooting, Nmap is also used for security auditing and identifying potential vulnerabilities.
