A packet sniffer is used to analyze the network traffic. Sometimes they are also called network analyzers, protocol analyzers or ethernet sniffers. System administrators usually use them to analyze the behaviour of an application or device causing network problems.

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.

SmartSniff allows you to capture TCP/IP packets that pass through your network adapter, and view the captured data as sequence of conversations between clients and servers. You can view the TCP/IP conversations in Ascii mode (for text-based protocols, like HTTP, SMTP, POP3 and FTP.) or as hex dump. (for non-text base protocols, like DNS)

VisualSniffer can be used by LAN administrators, and security professionals for network monitoring intrusion detection, and network traffic logging. It can also be used by network programmers for checking what the developing program has sent and received, or others to get a full picture of the network traffic. For example, parents may want to know what kids are doing online. If you stored important data in your PC, you may need to detect whether your data is sending out by some “Adware” or Spyware”. If you are a student, you may want to know how your network is working and the mechanism of each network protocol.
