Network Packet Capture / Protocol Analyzer Tools

Wireshark:
               is a network packet analyzer. A network packet analyzer will try to capture network packets and tries to display that packet data as detailed as possible.Wireshark can capture traffic from many different network media types - and despite its name - including wireless LAN as well. Which media types are supported, depends on many things like the operating system you are using

Capsa:
          is the name for a family of packet analyzer developed by Colasoft for network administrators to monitor, troubleshoot and analyze wired & wireless networks. Currently, there are three editions available: Capsa Enterprise Edition, Capsa Professional Edition, and Capsa Free .

Freeware Network Analyzer (Packet Sniffer) for students, teachers, computer geeks and other non-commercial purposes.

NetworkMiner:
                        is a Network Forensic Analysis Tool (NFAT) for Windows (but also works in Linux / Mac OS X / FreeBSD). NetworkMiner can be used as a passive network sniffer/packet capturing tool in order to detect operating systems, sessions, hostnames, open ports etc. without putting any traffic on the network. NetworkMiner can also parse PCAP files for off-line analysis and to regenerate/reassemble transmitted files and certificates from PCAP files.

NetworkMiner is a Network Forensic Analysis Tool (NFAT) for Windows that can detect the OS, hostname and open ports of network hosts through packet sniffing or by parsing a PCAP file. NetworkMiner can also extract transmitted files from network traffic.

SharpPcap:
                is a cross-platform packet capture framework for the .NET environment, based on the famous pcap / WinPcap libraries. It provides an API for capturing, injecting, analyzing and building packets using any .NET language such as C# and VB.NET.

Dsniff :

         is a collection of tools for network auditing and penetration testing. dsniff, filesnarf, mailsnarf, msgsnarf, urlsnarf, and webspy passively monitor a network for interesting data (passwords, e-mail, files, etc.). arpspoof, dnsspoof, and macof facilitate the interception of network traffic normally unavailable to an attacker (e.g, due to layer-2 switching). sshmitm and webmitm implement active monkey-in-the-middle attacks against redirected SSH and HTTPS sessions by exploiting weak bindings in ad-hoc PKI.

Tcpdump :

              is the network sniffer we all used before (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 and parsing logic for hundreds of application protocols) that Wireshark has, but it does the job well and with less security risk. It also requires fewer system resources. While Tcpdump 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.
