Сканер открытых портов

На данной странице представлены наиболее простые и популярные программы (оффлайн) и сервисы (онлайн), которые позволят вам просканировать открытые порты на своем собственном, либо удаленном компьютере(ах).

Онлайн сканеры

ИВИТ Сканирование портов

Онлайн сканер TCP и UDP портов от ИВИТ Очень простой русскоязычный онлайн сканер портов, который позволит просканировать доступные из интернета ресурсы. Для этого, достаточно знать адрес хоста, который будет сканироваться, выбрать нужные порты (на выбор доступны варианты из предустановленных популярных портов и указания своих), а так же выбрать протокол TCP или UDP (можно выбрать оба). Результат сканирования будет отображен в виде таблицы.

Hacker Target

Онлайн сканер TCP портов от Hacker Target Данный ресурс позволяет просканировать доступный в интернете хост на наличие открытых 10 популярных портов. Для работы используется nmap (про который мы еще напишем ниже), вывод результата так же отображается в виде консольного вывода этой программы.

Pentest Tools

Онлайн сканер TCP портов от Pentest Tools
Онлайн сканер UDP портов от Pentest Tools Сервис сканирования портов на английском языке, который позволяет провести тестирование на открытые порты TCP, с использованием программы nmap. Процесс сканирования nmap будет отображен в виде обычного консольного вывода данной программы, после чего будет сформирована таблица с результатами.

Кроссплатформенные (Windows, Linux) сканеры

В этом разделе будут описаны сканеры открытых портов, которые работают сразу на различных операционных системах, вроде Windows и Linux.

Angry IP Scanner

Официальный сайт Бесплатный сетевой сканер, который написан на языке Java. Обладает простым интерфейсом и позволяет просканировать определенные хосты на наличие у них открытых портов, номера которых заданы в настройках программы.

nmap

Официальный сайт Утилита nmap является одним из самых простых и доступных инструментов для сканирования открытых портов. У данной утилиты существуют версии под все популярные операционные системы — Windows, Linux, Mac OS X, FreeBSD и его аналоги, и т. д.

Например, мы хотим исследовать открытые порты на стороне сервера yandex.ru. Выполняем команду nmap yandex.ru и смотрим на результат:

recluse@hostsrv:~$ nmap yandex.ru Starting Nmap 7.60 ( https://nmap.org ) at 2020-11-01 18:31 MSK
Nmap scan report for yandex.ru (5.255.255.70)
Host is up (0.015s latency).
Other addresses for yandex.ru (not scanned): 5.255.255.77 77.88.55.70 77.88.55.77 2a02:6b8:a::a
Not shown: 998 filtered ports
PORT STATE SERVICE
80/tcp open http
443/tcp open https Nmap done: 1 IP address (1 host up) scanned in 4.51 seconds

Windows

Advanced Port Scanner 2

Официальный сайт Сравнительно простой в использовании сетевой сканер, разработанный теми же людьми, что сделали известную программу для удаленного доступа под названием Radmin. Для использования, достаточно указать диапазон сканируемых адресов и нажать на кнопку «Сканировать». Результат сканирования будет отображаться в реальном времени, с возможностью дальнейшего экспорта результата в Excel или текстовый файл.

PortQry

• -n — имя или ip адрес удаленного хоста
• -e — номер сетевого порта для сканирования (в случае, если нужно просканировать один сетевой порт)
• -p — используемый сетевой протокол — возможные значения — tcp, udp, both
• -r — диапазон портов для сканирования (в случае, если нужно просканировать несколько сетевых портов)

Например, для сканирования удаленного узла yandex.ru по обоим протоколам TCP и UDP с указанными портами 80 и 443, нужно будет выполнить следующую команду:

C:\PortQryV2>portqry -n yandex.ru -p both -o 80,443

Querying target system called:

Attempting to resolve name to IP address.

Name resolved to 77.88.55.88

TCP port 80 (http service): LISTENING

UDP port 80 (unknown service): LISTENING or FILTERED

TCP port 443 (https service): LISTENING

UDP port 443 (https service): LISTENING or FILTERED

Top Port Scanners on Ubuntu Linux

Here is a list of port scanners that work on Ubuntu/Linux.

1. Angry IP Scanner

Download and Install from http://www.angryip.org/
Fast and easy to use network scanner and port scanner.

To scan ports got to Tools > Preferences > Ports > Port Selection
Enter the ports you want to scan
Start the scan.

4. Nmap — network mapper

Install : sudo apt-get install nmap

Nmap is a utility for network exploration or security auditing. It supports ping scanning (determine which hosts are up), many port scanning techniques, version detection (determine service protocols and application versions listening behind ports), and TCP/IP fingerprinting (remote host OS or device identification). Nmap also offers flexible target and port specification, decoy/stealth scanning, sunRPC scanning, and more.

desktop:~$ nmap 192.168.1.2 -p1-255 Starting Nmap 5.21 ( http://nmap.org ) at 2011-10-23 19:29 IST Nmap scan report for 192.168.1.2 Host is up (0.00042s latency). Not shown: 252 closed ports PORT STATE SERVICE 21/tcp open ftp 22/tcp open ssh 80/tcp open http Nmap done: 1 IP address (1 host up) scanned in 0.38 seconds

nmap also has with an easy to use GUI frontends :

1. zenmap
Install : sudo apt-get install zenmap
http://nmap.org/zenmap/

2. Nmapsi4
Install : sudo apt-get install nmapsi4
http://www.nmapsi4.org/

3. Umit
Install : sudo apt-get install umit
