WinPcap is used as the network interface by many tools - both free and commercial including protocol analyzers, network monitors, network intrusion detection systems, sniffers, traffic generators, network testers, etc. For these reasons, WinPcap outperforms other comparable approaches.

WinPcap implements all of the classic optimizations described in the packet capture literature (e.g., kernel-level filtering and buffering, context switch mitigation, partial packet copy), plus some original ones, like JIT filter compilation and kernel-level statistic processing. WinDump can be used to watch, diagnose and save to disk network traffic according to various complex rules. is also the home of WinDump, the Windows version of the popular tcpdump tool. Some of these tools, like Wireshark, Nmap, Snort, ntop are known and used throughout the networking community. Thanks to its set of features, WinPcap is the packet capture and filtering engine of many open source and commercial network tools, including protocol analyzers, network monitors, network intrusion detection systems, sniffers, traffic generators and network testers. This library also contains the Windows version of the well known libpcap Unix API. WinPcap consists of a driver, that extends the operating system to provide low-level network access, and a library that is used to easily access the low-level network layers. As a suggestion, it would add to its value the possibility to copy certain entries to the clipboard or save the list of packets to a file.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. It comes with basic filtering capabilities but it does require further work to make it worth a try. Relying on WinPcap, Packet Sniffer can perform low-level network monitoring, allowing the quick capturing of all the packets that travel throughout a network interface. A network packet capturing tool that requires further work All this information might not be relevant to regular computer users but network administrators can surely use it to their advantage when trying to detect bottlenecks, suspicious transfers or other network-related issues. Aside from the packet type, Packet Sniffer also discloses the source and the destination port numbers, the TCP header size, checksum and window size, the sequence and the acknowledgement numbers, as well as the packet flags. They are all places in an organized table, which shows the time of the interception, the source and the destination IP or MAC addresses, along with the used protocol (TCP, UDP, etc) and the length of the packet.Ĭlicking on any of the packets reveals more details about it in the dedicated panel, in the lower side of the GUI. Detects all TCP and UDP packets that are sent and receivedĪll the packets that pass through the selected network interface are intercepted by Packet Sniffer. The working environment is very intuitive, enclosing two green and red buttons for starting and stopping the monitoring, respectively. Once you make your choice, the main window of Packet Sniffer is revealed.

The application can detect Ethernet, wireless network interfaces and local area connections, Bluetooth network connections, as well as host-only connections, such as those created by virtual machines. Upon launch, you will be greeted by a simple window that only comprises a drop-down menu containing all the network interfaces that your computer is connected to. No installation is required to launch Packet Sniffer, which means the application is ready to go whenever you need it.

As its name implies, Packet Sniffer is a network monitoring software utility designed to capture information about the ongoing data traffic and show you all the received and the sent packets.
