SmartSniff – Capture TCP/IP Packets on Network Adapter

SmartSniff is a network monitoring utility that 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)

SmartSniff provides 3 methods for capturing TCP/IP packets :

  1. Raw Sockets (Only for Windows 2000/XP or greater): Allows you to capture TCP/IP packets on your network without installing a capture driver.
  2. WinPcap Capture Driver: Allows you to capture TCP/IP packets on all Windows operating systems. (Windows 98/ME/NT/2000/XP/2003/Vista) In order to use it, you have to download and install WinPcap Capture Driver. This method is generally the preferred way to capture TCP/IP packets with SmartSniff, and it works better than the Raw Sockets method.
  3. Microsoft Network Monitor Driver (Only for Windows 2000/XP/2003): Microsoft provides a free capture driver under Windows 2000/XP/2003 that can be used by SmartSniff, but this driver is not installed by default, and you have to manually install it.
  4. Microsoft Network Monitor Driver 3: Microsoft provides a new version of Microsoft Network Monitor driver (3.x) that is also supported under Windows 7/Vista/2008. Starting from version 1.60, SmartSniff can use this driver to capture the network traffic.
    The new version of Microsoft Network Monitor (3.x) is available to download from Microsoft Web site.

SmartSniff allows you to easily export the captured data for using it in other applications:

  • The upper pane: you can select one or more items in the upper pane, and then copy them to the clipboard or save them to text/HTML/XML file.
  • The lower pane: You can select any part of the TCP/IP streams , copy the selected text to the clipboard, and then paste it to Notepad, Wordpad, MS-Word or any other editor. When you paste the selected streams to document of Wordpad, OpenOffice.org, or MS-Word, the colors are also transferred.
