Ethereal: The Protocol Analyzer that’s serious, simple, and free

Simply put, Ethereal is the best and easiest way to get a look at the raw data of any network traffic you want to capture. It’s free, it’s fast, and it’s powerful. Whether you’re an IT pro or just an internet user who wants to understand how your network traffic works, this protocol analyzer will be your go-to tool. Here’s how Ethereal stacks up against some of its most popular competitors like Wireshark and tcpdump (piped through BSD ‘dd’ ).

What Is Wireshark?

Wireshark is a network protocol analyzer application used for troubleshooting issues with network connectivity. It captures data packets from the live network interface or from a previously saved capture file (pcap) to reveal how data are transferred over networks. Wireshark is the world’s foremost network protocol analyzer. It lets you see what’s happening on your network at a microscopic level. It runs on most operating systems including Windows, Linux, Mac OS X and UNIX. You can use it in any of these four modes – Ethernet, IEEE 802.11, PPP/HDLC, ATM/DSL and USB – which makes it quite versatile when troubleshooting network problems. In this mode of operation, Ethereal offers an intuitive graphical user interface which displays current information about the system configuration and active programs as well as traffic captured by the tool; this makes it easy to locate items of interest. If you want to view traffic related only to a certain program like ping or ftp-data-transfer then you can apply filters using display filters to restrict the type of traffic displayed. You can also save captured sessions into files on disk for future reference or inspection purposes.

Who Uses Wireshark?

Anyone who wants to see what is going on in a network. Network administrators use it to troubleshoot network problems by examining packets. Network security people use it to analyze what hackers are doing to find vulnerabilities in the system. If you want to do packet analysis but not spend money, try this software out. There are several other programs like Wireshark available, however they cost a lot of money. Ethereal offers the same features as most other expensive programs with only a fraction of the price!

If you are looking for a network analyzer or an easy-to-use interface, then I highly recommend checking out Ethereal.

How Do I Use Wireshark?

Step 1. Download Wireshark Click on the down arrow below your web browser toolbar and select Save As… to download the application onto your desktop.

Step 2. Run the Application Click on the icon for Wireshark on your desktop to open it up. If you don’t see an icon for it in your toolbar, you can find it at Start -> All Programs -> Wireshark. Alternatively, you can just search wireshark in the search bar of Windows 8 or 10 (or press Windows+S) to bring up a search window with Wireshark listed as one of the options to choose from (though not necessarily first). Now go to Applications-> Internet-> Wireshark and click on the application.

Upon opening the program, you’ll be greeted with a console-like screen displaying three columns: one showing packets incoming, another outgoing, and the third scrolling between them.

To capture network traffic, click Capture, then Interfaces where you will see all available network interfaces. To start capturing packets right away, select an interface and hit Start.

To stop capturing packets right away (if nothing has been selected), click Stop Capture

Three Things To Know About Wireshark

Wireshark is a network protocol analyzer. It allows you to examine data from a live network or from a capture file on disk. You can interactively browse the capture data, viewing just the packet details you are interested in. You can also save packets for later examination or export them to text files for analysis with other tools. Wireshark can be used to troubleshoot network problems as well as monitor network activity.

  • Not every protocol will be supported
  •  Only traffic on your local system will be seen
  •  It’s only available for Windows and Linux operating systems , so Mac users will have to download an emulator like Wine if they want to use it. If there are features you would like to see added or things about its performance you would like to know about, please feel free to ask! Ethereal does not come without drawbacks; I’ve already mentioned it doesn’t support every protocol out there and cannot be installed on a Mac machine. However, if you’re looking for an open-source tool that is still incredibly powerful despite its lack of flashy graphics or pre-installed filters, Ethereal should fit your needs perfectly.
