It works by reading network packets, decoding them, and present them in an easy to understand format. Ethereal is open source software that can be downloaded and used on many popular platforms such as Windows, UNIX, and Linux. Ethereal is a powerful networking tool that can be used by network professionals for such purposes as troubleshooting, analysis, and protocol development.  \nSteps on how to download Ethereal software:  \nTo download Ethereal, follow these steps:  \n1. To download Ethereal, type [www.ethreal.com](www.ethreal.com) in your web browser and click Enter.  \n2. When the site appears, click the Download link from the top or the left menu.  \n3. When the download window appears, choose the correct version depending on your computer’s operating system. In this case, we are downloading Ethereal on Windows XP machine. Therefore, we will choose Main site under the Windows 98/ME/2000/XP/2003 Installers section in the [HTTP](HTTP)[ ](HTTP)row.  \n4. If you wish to capture live network packets, download and install the WinPcap packet capture driver. The recommended WinPcap version at the time of this writing is 3.0, which supports multiprocessor machines and Windows XP. The  \nWinpcap packet will appear as:   \nWinPcap_3_0.exe  \nNote: If you have an older version of WinPcap installed, you must un  \ninstall it before installing the current version.  \nNote: If you do not have WinPcap installed you will be able to open saved capture files, but you will not be able to capture live network traffic.  \n5. To download and install Ethereal, click the ethereal-setup-x.y.z.exe package. Atthe time of this writing, the latest version of ethereal is:  \nethereal-setup-0 .10.6.exe  \n6. After you click on the ethereal package, you will be asked to select a mirror. Select the following mirror:  \n7. When the File Download screen appears, click Save, and choose to which location you want to save the file.  \n8. After the download is complete, click Close from the File Download screen.  \n9. To install ethereal, double click the ethereal icon from the location where you have downloaded it to.  \n10. When the Open File screen appears, click Run, and follow the rest ofthe installation process.  \nCapturing Live Network Data:  \nTo capture live network data using ethereal, follow these steps:  \n1. To start ethereal, simply click the ethereal icon from the desktop or click Start> Programs > Ethereal.  \nEthereal.lnk  \n2. After you started Ethereal, select Start... from the Capture menu (or use the corresponding item in the \"Main\" toolbar), this brings up the Capture Options dialog box.  \nNote: If you are not sure which options to choose in the Capture Options dialog box, just try keeping the defaults as this should work well in many cases.  \n3. When the Capture Options dialog box appears, select the interface you want to capture on from the Interface dropdown menu. You can only capture on one interface, and you can only capture on interfaces that Ethereal has found on the system.  \n4. In the Buffer size text box, enter the buffer size to be used while capturing. This is the size of the kernel buffer which will keep the captured packets, until they are written to disk. If you encounter packet drops, try increasing this value.  \n5. Click the Capture packets in promiscuous mode option if you want to capture all packets on your LAN segment. If you do not specify this, Ethereal will only capture the packets going to or from your computer (not all packets on your LAN segment) .  \nNote: On a switched network, unicast traffic between two ports will not necessarily appear on other ports-only broadcast and multicast traffic will be sent to all ports. This means that even if you selected the promiscous mode, if you are connected to a switched network, you may not be able to see all trafic on your LAN segment.  \n6. The Limit each packet to option can be used to specify the maximam amount of data that will ","cbCaia2O6DGXiE5w","https://ap.wps.com/l/cbCaia2O6DGXiE5w","pdf",1269358,46,"English","# Installing and Using Ethereal\n## Downloading and Installing Ethereal\n## Capturing Live Network Data","[{\"question\":\"What is Ethereal and what is it used for?\",\"answer\":\"Ethereal is a network analyzer that captures network packets, decodes them, and displays results in an understandable format.
