Installing Wireshark on Ubuntu 12.04: A Step-by-Step Guide

As an Ubuntu Server administrator, you may encounter situations where you need to allow normal users to use Wireshark captures. By default, only superusers can capture packets with Wireshark. However, you can change this setting by following a few simple steps.

The first step is to add the allowed users to the wireshark group. This will give them the necessary permissions to run Wireshark captures. To do this, type the following command:

`sudo usermod -aG wireshark your_username`

Replace 'your_username' with the actual username of the user you want to add to the group.

If you need to allow each user individually to capture packets, there is an extra step you need to take. This involves setting the CAP_NET_RAW capability for each user. To do this, type the following command:

`sudo setcap cap_net_raw=ei /usr/bin/wireshark`

This will give each user the necessary permissions to run Wireshark captures.

To install Wireshark on your Ubuntu 12.04 system, you can use the APT package manager from a command line. First, update the package list by typing:

`sudo apt-get update`

Then, install the wireshark package by typing:

`sudo apt-get install wireshark`

During the installation process, you will be asked if you want to allow normal users to run a capture. Answer 'Yes' to this question.

After installing Wireshark, you can start using it to capture packets on your Ubuntu 12.04 system. Simply open Wireshark and select the interface you want to capture from. You can then start capturing packets by clicking on the 'Start' button.

In conclusion, installing Wireshark on Ubuntu 12.04 is a relatively simple process that requires a few command-line commands. By following these steps, you can allow normal users to use Wireshark captures and start using this powerful tool to troubleshoot network issues on your Ubuntu system.
