Dual mode packet analyzer:
Mode 1 (Packet interceptor)
Receive and analyze IP packets from your network or the internet. Analyze only the packets of interest to you by way of filtering; this filtering may be done by IP address, port, packet size, protocol, or sub-string searching of packet content. Also, you can search for a sub-string within the current list of packets, save the list of packets to a text file, view the contents of each packet, and more.
Mode 2 (HTTP file interceptor)
This mode collects packets of the HTTP protocol, analyzes the packets, constructs them into usable files, and then automatically saves these files to a user specified directory. These files may be web-pages, pictures, videos, downloads, and more. You may filter the saving of files by IP address, port, and/or file size.
Windows(c) 2000 / *XP / 2003 Server
*If you are using Windows XP Service Pack 2 (SP2), you will need to stop the Windows Firewall service (Windows Firewall/Internet Connection Sharing (ICS)) before you can capture traffic.
A screen resolution of at least 800x600 is highly recommended.
