Top 5 Most Welcomed Packet Sniffers

Colasoft Network AnalyzerAccording to the latest statistic from famous download sites regarding to downloads of packet sniffer softwares, the following products are very honored to be listed as top 5 most welcome packet sniffers by network engineers, IT managers, and network administrators etc.

#1 Wireshark - A Free Open Source Network Sniffer for Top Network Engineers

Wireshark (known as Ethereal until a trademark dispute in Summer 2006) is a fantastic open source network protocol analyzer for Unix and Windows. It allows you to examine data from a live network or from a capture file on disk. You can interactively browse the capture data, delving down into just the level of packet detail you need. Wireshark has several powerful features, including a rich display filter language and the ability to view the reconstructed stream of a TCP session. It also supports hundreds of protocols and media types. A tcpdump-like console version named tethereal is included. One word of caution is that Ethereal has suffered from dozens of remotely exploitable security holes, so stay up-to-date and be wary of running it on untrusted or hostile networks (such as security conferences).

#2 Colasoft Packet Sniffer - All-In-One & Easy-To-Use Network Analyzer and Packet Sniffers Available For Most Network Administrators.

Colasoft Packet Sniffer - Capsa performs real-time packet capturing, 24/7 network monitoring, advanced protocol analyzing, in-depth packet decoding, and automatic expert diagnosing. It allows you to get a clear view of the complex network, conduct packet level analysis, and troubleshoot network problems.

Whether you're a network administrator who needs to identify, diagnose, and solve network problems, a company manager who wants to monitor user activities on the network and ensure that the corporation's communications assets are safe, or a consultant who has to quickly solve network problems for clients, Capsa is the tool you need.

#3 Tcpdump: The Classic Sniffer For Network Monitoring And Data Acquisition

Tcpdump is the IP sniffer we all used before Ethereal (Wireshark) came on the scene, and many of us continue to use it frequently. It may not have the bells and whistles (such as a pretty GUI or parsing logic for hundreds of application protocols) that Wireshark has, but it does the job well and with fewer security holes. It also requires fewer system resources. While it doesn't receive new features often, it is actively maintained to fix bugs and portability problems. It is great for tracking down network problems or monitoring activity. There is a separate Windows port named WinDump. TCPDump is the source of the Libpcap/WinPcap packet capture library, which is used by Nmap among many other tools.

#4 Etherdetect : Connection-Oriented Packet Sniffer And Protocol Analyzer

EtherDetect Packet Sniffer is an easy for use and award-winning packet sniffer and network protocol analyzer, which provides a connection-oriented view for analyzing packets more effectively. With the handy tool, all you need to do is to set up the filter, start capturing, and view connections, packets as well as data on the fly.

#5 Ettercap : In Case You Still Thought Switched Lans Provide Much Extra Security

Ettercap is a terminal-based network sniffer/interceptor/logger for ethernet LANs. It supports active and passive dissection of many protocols (even ciphered ones, like ssh and https). Data injection in an established connection and filtering on the fly is also possible, keeping the connection synchronized. Many sniffing modes were implemented to give you a powerful and complete sniffing suite. Plugins are supported. It has the ability to check whether you are in a switched LAN or not, and to use OS fingerprints (active or passive) to let you know the geometry of the LAN.

  1. Not really a sniffer, but a repository for viewing and editing packet captures. Have you tried
