To find specific interesting packets, we can use Wireshark filters. The sheer volume of network traffic captured by Wireshark can be a bit overwhelming because, in addition to our HTTP traffic, every other packet to or from the system is captured. Let’s open any login page, and send a POST request to some server. So to sniff particularly POST data, you need to use filter inside Wireshark Filter Section bar. To stop the capture, you can click on the fourth icon on the top entitled Stop running the live capture, or you can navigate to Capture | Stop in the menu.

Here, Wireshark is listening to all network traffic and capturing them. In case of Linux, you can start the Wireshark by typing “ sudo wireshark” command in your terminal and select the interface and start the capturing process. In our case, we are connected with LAN (Ethernet), so we’ll go with an Ethernet Interface.

The output can be exported to XML, Postscript, CSV, and plaintext.

Live data can be read from IEEE 802.11, Bluetooth, and Ethernet.

Able to read/write many different capture file formats, such as tcpdump (libpcap), Network General Sniffer, Cisco Secure IDS iplog, Microsoft Network Monitor, and others.

Captured network data can be displayed via GUI or via a command-line TShark tool.

Has the most powerful display filters in the industry.

Ability to do live capture and offline analysis.

Once the driver is loaded, every local user can capture from it until it’s stopped again.įollowing are several Wireshark features: In windows, the WinPcap driver (called NPF) is loaded by Wireshark when it starts to capture live data. To be secure (at least in a way), it is recommended that even an administrator should always run in an account with (limited) user privileges, and only start processes that really need the administrator privileges.Īlso Read: Live Packet Sniffing with Python Script

The way this is done differs from operating system to operating system.

Start the Wireshark – You need to run Wireshark on an account with sufficient privileges to capture, or need to give the account on which you’re running Wireshark sufficient privileges to capture. Let’s take a look at the basics of using Wireshark to capture and analyze traffic. It can decode different protocols that it sees, so you could, for instance, reconstruct the audio of Voice over IP (VoIP) phone calls. Wireshark can be used to capture Ethernet, wireless, Bluetooth, and many other kinds of traffic. Wireshark is a graphical network protocol analyzer that lets us take a deep dive into the individual packets moving around the network.
