Компьютерийн сүлжээнд порт нь харилцаа холбооны төгсгөлийн цэг юм. Програм хангамжийн түвшинд, үйлдлийн системийн хүрээнд порт нь тодорхой процесс эсвэл сүлжээний үйлчилгээний төрлийг тодорхойлдог логик бүтэц юм. Порт дугаар, протокол, хаягийн хослол бүрт порт дугаар гэж нэрлэгддэг 16 битийн гарын үсэггүй тоогоор тодорхойлогддог. Порт дугаарыг ашигладаг хамгийн түгээмэл протокол бол Дамжуулалтын Хяналтын Протокол (TCP) ба Хэрэглэгчийн Дата Сүлжээний Протокол (UDP) юм.

Nmap нь пакет илгээх, хариултыг шинжлэх замаар компьютерийн сүлжээнд хостууд, үйлчилгээг олж илрүүлэхэд ашиглагддаг. IP порт скан хийх

Википедиа : Port (computer networking)(en)

In computer networking, a port is a communication endpoint. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service. A port is identified for each transport protocol and address combination by a 16-bit unsigned number, known as the port number. The most common transport protocols that use port numbers are the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP).

A port number is always associated with an IP address of a host and the type of transport protocol used for communication. It completes the destination or origination network address of a message. Specific port numbers are reserved to identify specific services so that an arriving packet can be easily forwarded to a running application. For this purpose, port numbers lower than 1024 identify the historically most commonly used services and are called the well-known port numbers. Higher-numbered ports are available for general use by applications and are known as ephemeral ports.

Ports provide a multiplexing service for multiple services or multiple communication sessions at one network address

Википедиа : Nmap(en)

Nmap (Network Mapper) is a free and open-source network scanner created by Gordon Lyon (also known by his pseudonym Fyodor Vaskovich). Nmap is used to discover hosts and services on a computer network by sending packets and analyzing the responses.

Nmap provides a number of features for probing computer networks, including host discovery and service and operating system detection. These features are extensible by scripts that provide more advanced service detection, vulnerability detection, and other features. Nmap can adapt to network conditions including latency and congestion during a scan.

Nmap started as a Linux utility and was ported to other systems including Windows, macOS, and BSD. It is most popular on Linux, followed by Windows.

Features

Nmap features include:

  • Host discovery – Identifying hosts on a network. For example, listing the hosts that respond to TCP and/or ICMP requests or have a particular port open.
  • Port scanning – Enumerating the open ports on target hosts.
  • Version detection – Interrogating network services on remote devices to determine application
