SmartSniff 1.80

Description: 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 :
  • Raw Sockets (Only for Windows 2000/XP or greater): Allows you to capture TCP/IP packets on your network without installing a capture driver. This method has some limitations and problems.
  • 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 from this Web site. (WinPcap is a free open-source 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.
  • 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, by using one of the following options:
  1. Option 1: Install it from the CD-ROM of Windows 2000/XP according to the instructions in Microsoft Web site
  2.  Option 2 (XP Only) : Download and install the Windows XP Service Pack 2 Support Tools. One of the tools in this package is netcap.exe. When you run this tool in the first time, the Network Monitor Driver will automatically be installed on your system.
  • 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.

Using SmartSniff

In order to start using SmartSniff, simply copy the executable (smsniff.exe) to any folder you like, and run it (installation is not needed).
After running SmartSniff, select "Start Capture" from the File menu, or simply click the green play button in the toolbar. If it's the first time that you use SmartSniff, you'll be asked to select the capture method and the network adapter that you want to use. If WinPcap is installed on your computer, it's recommended to use this method to capture packets.
After selecting the capture method and your network adapter, click the 'OK' button to start capturing TCP/IP packets. while capturing packets, try to browse some Web sites, or retrieve new emails from your email software. After stopping the capture (by clicking the red stop button) SmartSniff displays the list of all TCP/IP conversations the it captured. When you select a specific conversation in the upper pane, the lower pane displays the TCP/IP streams of the selected client-server conversation.
