Пинг порта через командную строку windows 10 — Ваш верный помощник с OS Windows

Команда ping — это сетевой инструмент для проверки работоспособности удаленной системы. Другими словами, команда определяет, доступен ли определенный IP-адрес или хост. Ping использует протокол сетевого уровня, называемый Internet Control Message Protocol (ICMP), и доступен во всех операционных системах.

С другой стороны, номера портов принадлежат протоколам транспортного уровня, таким как TCP и UDP. Номера портов помогают определить, куда пересылается Интернет или другое сетевое сообщение, когда оно приходит.

В этом руководстве вы узнаете, как проверить связь с портом в Windows и Linux с помощью различных инструментов.

Можно ли пропинговать конкретный порт?

Сетевые устройства используют протокол ICMP для отправки сообщений об ошибках и информации о том, успешна ли связь с IP-адресом. ICMP отличается от транспортных протоколов, поскольку ICMP не используется для обмена данными между системами.

Ping использует пакеты ICMP, а ICMP не использует номера портов, что означает, что порт не может быть опрошен. Однако мы можем использовать ping с аналогичным намерением — чтобы проверить, открыт порт или нет.

Некоторые сетевые инструменты и утилиты могут имитировать попытку установить соединение с определенным портом и ждать ответа от целевого хоста. Если есть ответ, целевой порт открыт. В противном случае целевой порт закрывается или хост не может принять соединение, потому что нет службы, настроенной для прослушивания подключений на этом порту.

Как пропинговать определенный порт в Linux?

Вы можете использовать три инструмента для проверки связи порта в Linux:

Telnet
Netcat (NC)
Network Mapper (nmap)

Пинг определенного порта с помощью Telnet

Telnet — это протокол, используемый для интерактивной связи с целевым хостом через соединение виртуального терминала.

1. Чтобы проверить, установлен ли уже telnet, откройте окно терминала и введите:

telnet

2. Если telnet не установлен, установите его с помощью следующей команды

Для CentOS/Fedora: yum -y install telnet
Для Ubuntu: sudo apt install telnet

3. Чтобы пропинговать порт с помощью telnet, введите в терминале следующую команду:

telnet [address] [port_number]

Где [address] — это домен или IP-адрес хоста, а [port_number] — это порт, который вы хотите проверить.

telnet google.com 443

Если порт открыт, telnet устанавливает соединение. В противном случае он указывает на сбой.

4. Чтобы выйти из telnet, нажмите Ctrl +] и введите q.

Пинг определенного порта с помощью Netcat

Netcat (nc) позволяет устанавливать соединения TCP и UDP, принимать оттуда данные и передавать их. Этот инструмент командной строки может выполнять множество сетевых операций.

1. Чтобы проверить, установлен ли netcat:

Для Debian, Ubuntu и Mint: введите netcat -h
Для Fedora, Red Hat Enterprise Linux и CentOS: ncat -h

2. Если netcat не установлен, выполните в терминале следующую команду:

sudo apt install netcat

3. Чтобы пропинговать порт с помощью netcat, введите следующее:

nc -vz [address] [port_number]

Выходные данные информируют пользователя об успешном подключении к указанному порту. В случае успеха — порт открыт.

Пинг определенного порта с помощью Nmap

Nmap — это сетевой инструмент, используемый для сканирования уязвимостей и обнаружения сети. Утилита также полезна для поиска открытых портов и обнаружения угроз безопасности.

1. Убедитесь, что у вас установлен Nmap, введя nmap -version в терминал.

Если Nmap установлен, вывод информирует пользователя о версии приложения и платформе, на которой он работает.

2. Если в вашей системе нет Nmap, введите следующую команду:

Для CentOS или RHEL Linux: sudo yum install nmap
Для Ubuntu или Debian Linux: sudo apt install nmap

3. После установки Nmap в системе используйте следующую команду для проверки связи определенного порта:

nmap -p [port_number] [address]

Выходные данные информируют пользователя о состоянии порта и типе службы, задержке и времени, прошедшем до завершения задачи.

4. Чтобы проверить связь с более чем одним портом, введите nmap -p [number-range] [address].

Синтаксис [number-range]— это диапазон номеров портов, которые вы хотите пропинговать, разделенные дефисом. Например:

nmap -p 88-93 google.com

Как пропинговать определенный порт в Windows?

Проверить связь с портом в Windows можно двумя способами:

Telnet
PowerShell

Пинг определенного порта с помощью Telnet

Перед использованием telnet убедитесь, что он активирован:

Откройте панель управления.
Щелкните «Программы», а затем «Программы и компоненты».
Выберите «Включение или отключение компонентов Windows».
Найдите клиент Telnet и установите флажок. Щелкните ОК.

Готово! Вы активировали клиент Telnet в системе.

После завершения активации можно пропинговать порт с помощью telnet. Для этого:

1. Введите cmd в поиске в меню «Пуск». Щелкните на приложение Командная строка.

2. В окне командной строки введите

telnet [address] [port_number]

Где [address] — это домен или IP-адрес хоста, а [port_number] — это порт, который вы хотите проверить.

Выходные данные позволяют узнать, открыт ли порт и доступен ли он, иначе отображается сообщение об ошибке подключения.

Пинг определенного порта с помощью PowerShell

PowerShell — это текстовая оболочка, которая по умолчанию поставляется с Windows.

Чтобы проверить связь с портом с помощью PowerShell, выполните следующие действия:

1. Введите PowerShell в поиске в меню «Пуск». Щелкните приложение Windows PowerShell.

2. В окне командной строке PowerShell введите:

Test-NetConnection [address] -p [port_number]

Если порт открыт и соединение прошло успешно, проверка TCP прошла успешно. В противном случае появится предупреждающее сообщение о том, что TCP-соединение не удалось.

Заключение

Теперь вы знаете, как выполнить эхо-запрос и проверить, открыт ли порт, с помощью нескольких сетевых инструментов и утилит в Linux и Windows.

The ping command is a network tool for checking whether a certain IP address or host is accessible using a network layer protocol called Internet Control Message Protocol (ICMP).

On the other hand, port numbers belong to transport layer protocols, such as TCP and UDP. Port numbers help identify where an Internet or other network message is forwarded when it arrives.

In this tutorial, you will learn how to ping a port in Windows, Linux, and macOS using different tools.

How to Ping Specific Port Number in Linux, Windows & macOS.

Prerequisites

A Linux, Windows, or macOS system.
Access to the terminal.
An account with sudo or root privileges.

Can You Ping a Specific Port?

Network devices use ICMP to send error messages and information on whether communication with an IP address is successful or not. ICMP differs from transport protocols as it is not used to exchange data between systems.

ping uses ICMP packets, and ICMP does not use port numbers, which means a port cannot be pinged. However, there are tools that can check if a port is open.

Some network tools and utilities simulate an attempt to connect to a specific port and wait to see if the target host responds. If there is a response, the target port is open. If not, the target port is closed, or the host cannot accept a connection because there is no service configured to listen for connections on that port.

How to Ping a Specific Port in Linux

There are several tools to check whether a port is open in Linux. They are:

‎Telnet.
Netcat (nc).
‎Network Mapper (nmap).
Curl.

Ping a Port Using Telnet

Telnet is a protocol for interactive communication with the target host via a virtual terminal connection. To ping a port using telnet, run:

telnet [address] [port-number]

The [address] is the domain or the host IP address, while [port-number] is the port you want to ping. For example, run the following:

telnet google.com 443

If the port is open, Telnet establishes a connection. Otherwise, it states a failure.

Ping a Port Using Netcat

Netcat (nc) reads and writes from connections using TCP and UDP protocols. This command-line tool performs many network operations.

To ping a port using Netcat, enter the following:

nc -vz [address] [port-number]

In the command, the -v argument enables detailed output, and -z checks if the port is open without sending data.

For example, run the following;

nc -vz google.com 443

The output states whether the connection to the specified port is successful. If it is successful, the port is open.

Ping a Port Using Nmap

Nmap is a network tool used for vulnerability scanning and network discovery. The utility is also useful for finding open ports and detecting security risks.

Note: Be aware of legal ramifications regarding improper Nmap use, such as flooding a network or crashing a system.

Use the following command to ping a specific port with Nmap:

nmap -p [port-number] [address]

The -p option specifies the port or port range you want to scan on the target address. For example, run the following:

nmap -p 443 google.com

The output informs the user about the port’s state and service type, latency, and the time elapsed until the task completion.

To ping more than one port, enter:

nmap -p [number-range] [address]

The [number-range] is the port number range you want to ping, separated by a hyphen.

For example:

nmap -p 88-93 google.com

nmap -p 88-93 google.com terminal output.

Ping a Port Using curl

The curl command is designed to make HTTP/HTTPS requests. However, use curl to check if a specific port is open by attempting an HTTP or HTTPS connection to that port.

The syntax is:

curl [address]:[port-number]

For example, to check if port 443 (used for HTTPS) is open on Google using curl, run:

curl https://google.com:443

curl https://google.com:443 terminal output

How to Ping a Specific Port in Windows

Learn how to test the availability of a specific port in Windows using different tools. The following text explains how to ping a specific port in Windows using Telnet and PowerShell.

Ping a Port Using Telnet

Before using Telnet, make sure it is activated. To do that, follow these steps:

1. Open the Control Panel.

2. Click Programs.

3. Select Programs and Features.

4. Select Turn Windows features on or off.

5. Find Telnet Client and check the box. Click OK.

You activated the Telnet Client on the system. After completing the activation, access the cmd and use the following command.

telnet [address] [port-number]

The [address] is the domain or the host’s IP address, while [port-number] is the port number you want to ping. For example, run:

telnet google.com 443

If the connection is successful, you’ll see a blank screen or a message indicating the connection is open.

Ping a Port Using PowerShell

PowerShell is a text-based shell that comes with Windows by default. To ping a port using PowerShell, enter the following in the PowerShell prompt window:

Test-NetConnection [address] -p [port-number]

For example, run:

Test-NetConnection google.com -p 443

Test-NetConnection google.com -p 443 Power Shell output

The TCP test is successful if the port is open and the connection is established. Otherwise, a warning message appears saying the TCP connection failed.

How to Ping a Specific Port in macOS

There are several ways to test whether a specific port is open on a remote server using tools available on macOS, such as Netcat, Telnet, and Curl.

Read the following text to learn how to ping a specific port in macOS.

Ping a Port Using nc (Netcat)

To test if a specific port is open, use the following command:

nc -zv [address] [port-number]

For example, run:

nc -zv google.com 443

nc -zv google.com 443 command line output

The -z option tells nc to scan for open ports without sending any data. The -v enables verbose mode. Therefore, it provides detailed output.

Ping a Port Using Telnet

The telnet command also checks if a specific port is open. To do it, run the following:

telnet <address> <port_number>

For example, run:

telnet google.com 443

You’ll see a blank screen if the connection is successful.

Ping a Port Using curl

The curl command is helpful for testing HTTP or HTTPS ports (like 80 or 443). The syntax is:

curl -I [address]

For example, run the following:

curl -I https://google.com

3. Press Enter.
4. Wait for the results of the ping test.

To ping a port on Windows 10 Using Telnet:

First, ensure Telnet is installed on your Windows 10 machine:

Go to Control Panel.
Choose Programs and Features.
Select Turn Windows features on or off.
Scroll down and check Telnet Client.
Click OK and wait for it to install.

Once installed, open the Command Prompt and use the following command:

telnet <Hostname_or_IP> <PortNumber>

If the port is open, the window will go blank or display a connected message. If it’s closed or if there’s an issue, you’ll see a «Could not open connection» error.

Remember that even if a port is not responding to a telnet or PowerShell check, it doesn’t mean the port isn’t being used or active; it might be set to not respond, or there could be a firewall or other security measures in place. Always approach port checks and scans with caution and ensure you have permission to probe the target system.

How do I ping a specific port?

How do I test a port?

Nmap (Network Mapper) is a versatile and powerful tool for network discovery and security scanning. One of its primary uses is to check if specific ports on a system are open. Here’s how you can use Nmap to test a port:

Install Nmap:
- If you haven’t installed Nmap on your system, you can download and install it from the official website: https://nmap.org/download.html
Basic Port Scan:
- Open a command-line interface or terminal.
- To test a specific port, use the following command:
  
  nmap -p <PortNumber> <Hostname_or_IP>
Scan Multiple Ports:
- You can also test multiple ports by separating them with commas or using a range with a hyphen.

nmap -p 80,443 example.com # Tests port 80 and 443
nmap -p 20-30 example.com # Tests ports from 20 to 30 inclusive

4. Scan Most Common Ports:

Nmap has a list of the 1,000 most common ports. To scan these, you don’t need to specify any port:
Use the -T4 option for faster execution (be cautious as this might be flagged by intrusion prevention systems).
Use the -v option for verbose mode to get more details.
Use the -sV option to determine the version of the service running on the port.

Example combining the options:

nmap -p 80,443 -T4 -v -sV example.com

Note: Always ensure you have permission to scan the target. Unauthorized scanning can be illegal and unethical. If you’re scanning a system or network that you do not own or have explicit permission to test, you could face legal consequences.
