“CommView is a program for monitoring Internet and Local Area Network (LAN) activity capable of capturing and analyzing network packets. It gathers information about data passing through your dial-up connection or Ethernet card and decodes the analyzed data. With CommView you can see the list of network connections and vital IP statistics and examine individual packets. Packets are decoded down to the lowest layer with full analysis of the most widespread protocols. Full access to raw data is also provided. Captured packets can be saved to log files for future analysis. A flexible system of filters makes it possible to drop packets you don’t need or capture only those packets that you wish to capture. This application is designed for Internet users and small and medium-sized networks and can run on any Windows system. It requires an Ethernet or Wireless Ethernet network card supporting the NDIS 3.0 driver standard, or a standard dial-up adapter.”

“AnalogX PacketMon allows you to capture IP packets that pass through your network interface – whether they originated from the machine on which PacketMon is installed, or a completely different machine on your network! Once the packet is received, you can use the built in viewer to examine the header as well as the contents, and you can even export the results into a standard comma-delimited file to importing into your favorite program. As if that’s not enough, PacketMon has a powerful rule system that allows you to narrow down the packets it captures to ensure you get EXACTLY what you’re after, without tons of unrelated information.”

“What They Are and How to Protect Yourself
Have you ever thought about how your computer talks with others on a network? Would you like to listen to, or ‘sniff’, the conversation? Network engineers, system administrators, security professionals and, unfortunately, crackers have long used a tool that allows them to do exactly that. This nifty utility, known as a sniffer, can be found in the arsenal of every network guru, where it’s likely used everyday for a variety of tasks. This article will offer a brief overview of sniffers, including what they do, how they work, why users need to be aware of them, and what users can do to protect themselves against the illegitimate use of sniffers.”

“WebSiteSniffer is a packet sniffer tool that captures all Web site files downloaded by your Web browser while browsing the Internet, and stores them on your hard drive under the base folder that you choose. WebSiteSniffer allows you to choose which type of Web site files will be captured: HTML Files, Text Files, XML Files, CSS Files, Video/Audio Files, Images, Scripts, and Flash (.swf) files.
“While capturing the Web site files, the main window of WebSiteSniffer displays general statistics about the downloaded files for every Web site / host name, including the total size of all files (compressed and uncompressed) and total number of files for every file type (HTML, Text, Images, and so on).
• When downloading a large file with a fast Internet connection, WebSiteSniffer might lose some of the packets, and thus the captured file will be corrupted.
• If some of the Web site files are taken from the cache of your Web browser, WebSiteSniffer won’t be able to capture them. To ensure that all Web site files are captured by WebSiteSniffer, clear the cache of your Web browser, or use the ‘Start Private Browsing’ option of Firefox.”

“WinPcap is the industry-standard tool for link-layer network access in Windows environments: it allows applications to capture and transmit network packets bypassing the protocol stack, and has additional useful features, including kernel-level packet filtering, a network statistics engine and support for remote packet capture.
“Every version of WinPcap comes with a developer’s pack that includes documentation, libraries and include files needed to immediately start with your own new application. The developer’s pack contains a set of sample programs ready to be compiled both with Visual Studio and Cygnus, and are available as excellent starting points.
“This library also contains the Windows version of the well known libpcap Unix API. WinPcap is completely compatible with libpcap. This means that you can use it to port your existing Unix or Linux tools to Windows. This also means that your Windows applications will be easily portable to Unix.”
