How to Install Wireshark Package in Kali Linux 2020.1

Можно взять и запустить Wireshark от root пользователя, но это плохая идея.
Сам по себе Wireshark может быть уязвим для некорректного трафика (случайного или преднамеренного), который  может навредить системе и нарушить ее правильную работу.

Естественно возникает вопрос: Если мы не можем запускать Wireshark с правами администратора, как же мы получим доступ к сетевому интерфейсу и захватим пакеты?

Здесь я приведу инструкцию по настройке запуска Wireshark от не-root пользователя на примере Debian дистрибутива (проверено также в Linux Mint, Ubuntu).

Установить компонент setcap:

sudo apt-get install libcap2-bin

Дождаться окончания установки.

Создать группу Wireshark

Назначить dumpcap исполняемым от группы Wireshark и изменить права доступа.

chgrp wireshark /usr/bin/dumpcap

chmod 750 /usr/bin/dumpcap

Запустить Wireshark от своего имени, и обратить внимание, что на этот раз будет виден полный список сетевых адаптеров.

Если же этого не произошло, то обязательно проверить, что группа Wireshark присутствует в списке групп.

Features

Wireshark contains several useful features, the foremost of which are listed below:

  • Inspecting thousands of protocols
  • New protocols being added with every update
  • Live-capturing of protocols with offline analysis
  • Three-way handshake
  • Maximum portability: runs on Solaris, Linux, Windows, MAC OS X, FreeBSD, and more
  • Analyzing VoIP protocols
  • Reads data from many platforms, i.e., Wi-Fi, Ethernet, HDLC, ATM, USB, Bluetooth, Frame Relay, Token Ring, and more
  • Results can be saved in CSV, XML, PostScript, and plain text documents
  • Reads and write a wide variety of captured file formats

При запуске wireshark ругается, что это опасно и все такое и просит убедится, что нет способа получше. Его действительно нет и надо работать от рута?

===== РЕШЕНИЕ =====

1. Запускаем переконфигурацию пакета, читаем что пишет, разрешаем захват пакетов.

dpkg-reconfigure wireshark-common2. Добавляем себя в группу wireshark

Итак, чтобы запускать без рута:

1. Запускаем переконфигурацию пакеты, читаем что пишет, разрешаем захват пакетов.

dpkg-reconfigure wireshark-common2. Добавляем себя в группу wireshark

Однако вопрос. При переконфигурации пакета сообщается, что разрешение захвата пакета влияет на безопасность. Вопрос, что хуже работать под рутом, или разрешить wireshark и пользователю от которого работаешь захват пакетов без повышения привелегий? Наверное хуже запускать программу от рута, т.к. предами срет (не удобно) и вообще от рута граф. проги гонять лишний раз не охота.

Вообще, приложения другого юзверя обычно фигово взаимодействуют с dbus, gvfs, gnome-keyring в текущем сеансе.
И владельцем конфигов в хомяке может стать другой пользователь, что тоже потом вылезет боком при попытке их изменения/удаления/перемещения.

Наверное хуже запускать программу от рута

Пожалуй, за одним исключением: необходимость запуска в сеансе какого-нибудь офисного планктона, которому не стоит давать лишних прав.

About the author

I am a freelancing software project developer, a software engineering graduate and a content writer. I love working with Linux and open-source software.

Wireshark is a network packet analyzer. It captures every packet getting in or out of a network interface and shows them in a nicely formatted text. It is used by Network Engineers all over the world.

In this article, I will show you how to install Wireshark on Ubuntu and how to use it. I am using Ubuntu 18.04 LTS for the demonstration. But it should work on any LTS version of Ubuntu still supported at the time of this writing. Let’s get started.

Installing Wireshark:

Wireshark is available in the official package repository of Ubuntu 14.04 LTS and later. So it is really easy to install.

How to Install Wireshark Package in Kali Linux 2020.1

The APT package repository cache should be updated.

How to Install Wireshark Package in Kali Linux 2020.1

apt wireshark

How to Install Wireshark Package in Kali Linux 2020.1

Now press y and then press <Enter>.

How to Install Wireshark Package in Kali Linux 2020.1

By default, Wireshark must be started as root (can also be done with sudo) privileges in order to work. If you want to run Wireshark without root privileges or without sudo, then select <Yes> and press <Enter>.

How to Install Wireshark Package in Kali Linux 2020.1

Wireshark should be installed.

How to Install Wireshark Package in Kali Linux 2020.1

Starting Wireshark:

Now that Wireshark is installed, you can start Wireshark from the Application Menu of Ubuntu.

How to Install Wireshark Package in Kali Linux 2020.1

If you did not enable Wireshark to run without root privileges or sudo, then the command should be:

Wireshark should start.

Capturing Packets Using Wireshark:

When you start Wireshark, you will see a list of interfaces that you can capture packets to and from.

How to Install Wireshark Package in Kali Linux 2020.1

There are many types of interfaces you can monitor using Wireshark, for example, Wired, Wireless, USB and many external devices. You can choose to show specific types of interfaces in the welcome screen from the marked section of the screenshot below.

How to Install Wireshark Package in Kali Linux 2020.1

Here, I listed only the Wired network interfaces.

How to Install Wireshark Package in Kali Linux 2020.1

Now to start capturing packets, just select the interface (in my case interface ens33) and click on the Start capturing packets icon as marked in the screenshot below. You can also double click on the interface that you want to capture packets to and from to start capturing packets on that particular interface.

How to Install Wireshark Package in Kali Linux 2020.1

You can also capture packets to and from multiple interfaces at the same time. Just press and hold <Ctrl> and click on the interfaces that you want to capture packets to and from and then click on the Start capturing packets icon as marked in the screenshot below.

How to Install Wireshark Package in Kali Linux 2020.1

Using Wireshark on Ubuntu:

I am capturing packets on the ens33 wired network interface as you can see in the screenshot below. Right now, I have no captured packets.

How to Install Wireshark Package in Kali Linux 2020.1

I pinged google.com from the terminal and as you can see, many packets were captured.

How to Install Wireshark Package in Kali Linux 2020.1

Now you can click on a packet to select it. Selecting a packet would show many information about that packet. As you can see, information about different layers of TCP/IP Protocol is listed.

How to Install Wireshark Package in Kali Linux 2020.1

You can also see the RAW data of that particular packet.

How to Install Wireshark Package in Kali Linux 2020.1

You can also click on the arrows to expand packet data for a particular TCP/IP Protocol Layer.

How to Install Wireshark Package in Kali Linux 2020.1

Filtering Packets Using Wireshark:

On a busy network thousands or millions of packets will be captured each second. So the list will be so long that it will be nearly impossible to scroll through the list and search for certain type of packet.

The good thing is, in Wireshark, you can filter the packets and see only the packets that you need.

To filter packets, you can directly type in the filter expression in the textbox as marked in the screenshot below.

How to Install Wireshark Package in Kali Linux 2020.1

How to Install Wireshark Package in Kali Linux 2020.1

A new window should open as shown in the screenshot below. From here you can create filter expression to search packets very specifically.

How to Install Wireshark Package in Kali Linux 2020.1

In the Field Name section almost all the networking protocols are listed. The list is huge. You can type in what protocol you’re looking for in the Search textbox and the Field Name section would show the ones that matched.

How to Install Wireshark Package in Kali Linux 2020.1

In this article, I am going to filter out all the DNS packets. So I selected DNS Domain Name System from the Field Name list. You can also click on the arrow on any protocol

How to Install Wireshark Package in Kali Linux 2020.1

And make your selection more specific.

How to Install Wireshark Package in Kali Linux 2020.1

You can also use relational operators to test whether some field is equal to, not equal to, great than or less than some value. I searched for all the DNS IPv4 address which is equal to 192.168.2.1 as you can see in the screenshot below.

How to Install Wireshark Package in Kali Linux 2020.1

The filter expression is also shown in the marked section of the screenshot below. This is a great way to learn how to write filter expression in Wireshark.

How to Install Wireshark Package in Kali Linux 2020.1

Once you’re done, just click on OK.

How to Install Wireshark Package in Kali Linux 2020.1

Now click on the marked icon to Apply the filter.

How to Install Wireshark Package in Kali Linux 2020.1

As you can see, only the DNS protocol packets are shown.

How to Install Wireshark Package in Kali Linux 2020.1

Stopping Packet Capture in Wireshark:

You can click on the red icon as marked in the screenshot below to stop capturing Wireshark packets.

How to Install Wireshark Package in Kali Linux 2020.1

Saving Captured Packets to a File:

You can click on the marked icon to save captured packets to a file for future use.

How to Install Wireshark Package in Kali Linux 2020.1

Now select a destination folder, type in the file name and click on Save.

How to Install Wireshark Package in Kali Linux 2020.1

The file should be saved.

How to Install Wireshark Package in Kali Linux 2020.1

Now you can open and analyze the saved packets anytime. To open the file, go to File > Open from Wireshark or press <Ctrl> + o

Then select the file and click on Open.

How to Install Wireshark Package in Kali Linux 2020.1

The captured packets should be loaded from the file.

How to Install Wireshark Package in Kali Linux 2020.1

So that’s how you install and use Wireshark on Ubuntu. Thanks for reading this article.

Comments

  • sudo apt-get install wireshark
    sudo dpkg-reconfigure wireshark-common 
    sudo usermod -a -G wireshark $USER
    (restart)
    
    sudo -s -u $USER wireshark
    
    no protocol specified
    gtk-warning ** cannot open display
    

    The «no protocol specified» part seems pretty straight forward. And the gtk-warning cannot open display seems to relate exactly to this issue.

    «You have two ways to get this working: grant it or have root take it.
    You (greg) can grant it by means of ‘xhost local:root’. Or root can take it, because it can access your files:
    ‘export AUTHORITY=/home/greg/.Xauthority’.»

  • Why do you suggest to use a ppa? Wireshark is available in the standard repository.

  • sudo chmod +x /usr/bin/dumpcap did the trick

  • Attention people: NEVER install things from random ppas from the internet. It’s just a repository compiled by anyone. And this is very dangerous

Solution 3

You can also run Wireshark with root privileges by running gksu wireshark from the terminal.

  • Capture privileges: Most UNIXes
  • Security including:
  • Debian README (also applies to Ubuntu)

Solution 1

For WireShark there’s a better way. The bit that normally needs root is the packet collection application and this can be configured to allow certain people to use it without sudo, gksu, etc.

In a terminal (very important that you’re in a terminal, not just the Alt+F2 dialogue) run this:

sudo dpkg-reconfigure wireshark-common

Reconfiguring wireshark-common

This adds a wireshark group. Anybody in that group will be able to sniff without being root. This is obviously more secure than just letting anybody sniff but does mean there’s no password checking. Technically any person with access to a computer logged in with a wireshark account will be able to sniff. If that’s acceptable to you, carry on.

If not, run that again and select no.

sudo adduser $USER wireshark

And restart or log out. When you’re back in it should let you start sniffing without any fuss about being root.

Solution 4

you can try this also, open the terminal, run this command

# setcap 'CAP_NET_RAW+eip CAP_NET_ADMIN+eip' /usr/bin/dumpcap

Solution 2

Really you do not need to launch WireShark as root. Please read official page. In brief you should do:

sudo groupadd wireshark
sudo usermod -a -G wireshark $USER
sudo chgrp wireshark /usr/bin/dumpcap
sudo chmod o-rx /usr/bin/dumpcap
sudo setcap 'CAP_NET_RAW+eip CAP_NET_ADMIN+eip' /usr/bin/dumpcap
sudo getcap /usr/bin/dumpcap

Then log-out and log-in again.

Note: this method was tested on 16.04 LTS, 17.10 and 18.04 LTS.

Solution 1

As has been pointed out by Guerlando Ocs you may encounter a situation where the group wireshark doesn’t exist. In this case you can resolve the problem by first running

sudo dpkg-reconfigure wireshark-common 

Enabling Non-root Capture

Step 1: Install setcap

First, we’ll need to install thesetcapexecutable if it hasn’t been already. We’ll use this to set granular capabilities on Wireshark’sdumpcapexecutable.setcapis part of the libcap2-bin package.

Step 2: Create a Wireshark Group (Optional)

[email protected]# groupadd wireshark
[email protected]# usermod -a -G wireshark stretch
[email protected]$ newgrp wireshark
[email protected]# chgrp wireshark /usr/bin/dumpcap
[email protected]# chmod 750 /usr/bin/dumpcap

Step 3: Grant Capabilities

Granting capabilities withsetcapis a simple matter:

[email protected]# setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap

In case you’re wondering, that=eipbit after the capabilities list grants them in the effective, inheritable, and permitted bitmaps, respectively. A more thorough explanation is provided in section 2 ofthis FAQ.

To verify our change, we can usegetcap:

[email protected]# getcap /usr/bin/dumpcap
/usr/bin/dumpcap = cap_net_admin,cap_net_raw+eip
        ----for example: USER is atxuser----

        ----add USER atxuser to GROUP wireshark----
        [[email protected] robot]# groupadd wireshark
        [[email protected] robot]# usermod -a -G wireshark atxuser

        ----switch to atxuser and add GROUP wireshark----
        [[email protected] robot]# su - atxuser
        [[email protected] ~]$ newgrp wireshark
        [[email protected] ~]$ exit

        ----Grant Capabilities----
        [[email protected] robot]# chgrp wireshark /usr/sbin/dumpcap
        [[email protected] robot]# chmod 750 /usr/sbin/dumpcap
        [[email protected] robot]# setcap cap_net_raw,cap_net_admin=eip /usr/sbin/dumpcap
        [[email protected] robot]# getcap /usr/sbin/dumpcap
        /usr/sbin/dumpcap = cap_net_admin,cap_net_raw+eip

        ----to check if tshark can be working fine with non-root user----
        [[email protected] robot]#su - atxuser
        [[email protected] ~]$ tshark -i eth0 -a duration:10 -V -T pdml &> dump.xml &
