PacketMon

A useful program for knowing if a particular program is using the internet, and even viewing the communications. Do you need to log certain network activity, but have no easy means to do so?
Or are you just bored and looking for a new network toy to play with? Whether youre a network administrator, network programmer or power user, AnalogX PacketMon is a fast and simple to use network monitor!
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.
PacketMon has a powerful rule system that allows you to narrow down the packets it captures to ensure you get what youre after, without tons of unrelated information.
