What Is Sniphere?: Sniphere is a freeware protocol analyzer and network packet capturing (packet sniffer) utility for Windows-based computers using WinPCap.
Faster Than a Speeding Packet: Sniphere set out to separate itself from the freeware competition by the speed at which it captures and analyzes network packets. Sniphere claims to have a superior packet capturing speed comparable with commercial sniffer products such as Iris.
Targeted Tracking: Sniphere's "tracking mode" allows you to specify two IP addresses and then capture and view only the packets between those 2 hosts.
Decode Mode: The Decode Mode is used to reassemble a TCP session. You just select a packet and it will find all the other packets in your current log which belong to the same TCP session and convert it to clear text for you.
