Observer provides a comprehensive drill-down into network traffic and provides back-in-time analysis, reporting, trending, alarms, application tools, and route monitoring capabilities.This feature is a great way to monitor the network in real time, and show from where in the world that traffic is coming.OmniPeek sniffer displays a Google Map in the OmniPeek capture window showing the locations of all the public IP addresses of captured packets.Network Packet Analyzer: OmniPeek Network Analyzer Capsa Network Analyzer captures all data transmitted over the network and provides a wide range of analysis statistics in an intuitive and graphic way.Packet Sniffing Tool: Capsa Network Analyzer TCPDump: Runs on Linux and UNIX systems (重要).TCPdump is a command line interface packet sniffer which runs on Linux and Windows.StellCentral Packet Analyzer provides a graphical console for high-speed packet analysis.Sniffing Tool: StellCentral Packet Analyzer Masks out arp, icmp, dns, or other protocols and allows you to view traffic of you interest:.Displays all TCP packets that contain the word 'traffic':.Displays all retransmissions in the trace:.Set a filter for the HEX values of 0x33 0x27 0x58 at any offset:.Example: Type the protocol in the filter box arp, http, tcp, udp, dns, ip.Display filters are used to change the view of packets in the captured files.Use this tool to find passwords in a Telnet session or make sense of a data stream. The tool sees TCP data in the same way as that of the application layer.A set of filters for customized data display can be refined using a display filter.Captured files can be programmatically edited via command-line.It captures live network traffic from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI networks.Wireshark uses Winpcap to capture packets, so it can only capture the packets on the networks supported by Winpcap.It lets you capture and interactively browse the traffic running on a computer network.7.7 Sniffing Tools Sniffing Tool: Wireshark
