What is Wireshark And How It Works Its Code

    Last Updated on: 15th April 2023, 05:39 pm

    Wireshark is a free and open-source packet analyzer. It is often called the “Ethernet protocol analyzer” because it was originally developed to monitor Ethernet traffic. In contrast to network sniffing software that captures packets at the TCP/IP level, Wireshark intercepts packets at higher layers of the OSI model—the IEEE 802 Networks layer (layer 2) and above, including Ethernet traffic as well as host-to-host protocols like IPX/SPX, AppleTalk and NetBIOS over TCP/IP.

    Wireshark is An Open-Source Packet Analyzer And Network Protocol Analyzer.

    Wireshark is an open-source packet analyzer and network protocol analyzer. It can capture and decode packets for analysis, including live traffic on a network.

    A packet analyzer is a tool that helps you understand what’s happening in your network. It can also be used to troubleshoot problems by examining packets as they transit through your networks.

    A network protocol analyzer has similar capabilities to those of a packet analyzer but focuses primarily on analyzing the binary format of IP datagrams, allowing it to perform deeper analysis than what’s possible with other tools like tcpdump or Ethereal/Wireshark themselves (without using any third party applications).

    Wireshark is A Useful Tool to Determine The Cause of Slow network connections.

    Wireshark is a useful tool to determine the cause of slow network connections. It also provides information on performance issues, such as packet loss and latency.

    Wireshark can be used to identify what type of problem you’re experiencing so that you can narrow down your search for solutions.

    Wireshark Can Also Help in Finding Network Issues, Such as Slow Network Response Times

    Wireshark can also help in finding network issues, such as slow network response times.

    The following example shows how to use Wireshark to find the cause of slow network traffic:

    • Start Wireshark and open a capture file with your target PC or device using File > Open Capture File… (or press Ctrl+O).
    • On the top toolbar, click Protocol Hierarchy in Decode Mode and select TCP from this drop-down menu. Then click Transport Stream 1/2 (TS1) so that only this protocol is shown in the display pane below it.
    • Now select any packets whose destination address matches yours but whose source address does not match yours; for example, if your PC has an IP address 192.168.*.* then you would select packets whose destination port number was 8080 because this is typically used by web servers such as Google’s Web Server Hosting Service which runs on port 8080

    Wireshark is Complex, Hence a Tutorial Has Been Provided, If You Are New To Wireshark You Should Definitely Read It Through

    Wireshark is a complex application. It is therefore very important that you understand the basics of Wireshark before you start using it.

    A tutorial has been provided to help you get started, so if this is your first time using Wireshark then we recommend reading through the tutorials available online at [Wireshark official website](https://www.wireshark.org/docs/wsug/tutorials).

    These tutorials are free and easy to follow, but they do require some basic knowledge about network protocols such as TCP/IP or UDP/IP, etc.

    Wireshark is Cross-Platform, Using The GTK+ Widget Toolkit In Current Releases, And Qt In The Development Version.

    Wireshark is a network protocol analyzer, which can capture and decode packets sent over a network. It works by using the libpcap library to capture packets and filter them into distinct fields such as source address, destination address, timestamp, and more.

    This allows you to inspect the contents of those packets for potentially useful information about suspicious activities on your network or among your users’ devices.

    Wireshark also has an extensive set of tools for displaying these data in tabular form as well as visualizing the relationships between various elements within each packet (e.g., how many bytes are contained within each frame).

    For Heavy Users of The Wireshark GUI Interface, The Best Way Forward Might Be To Move To tshark As a Command Line Tool

    For heavy users of the Wireshark GUI interface, the best way forward might be to move to tshark as a command line tool.

    The tshark utility is a version of Wireshark that can be used from the command line. It’s faster than the GUI version and can be used for troubleshooting network problems or analysis purposes such as packet capture files.


    In conclusion, Wireshark is one of the best open-source tools available for network analysis. It can be used to perform packet capture and analysis, as well as to display packet information on TCP and UDP interfaces. With this tool, you will be able to troubleshoot network problems such as slow response times or lack of connectivity in your network environment.
