SmartSniff 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)

System Requirements:

SmartSniff can capture TCP/IP packets on any 32-bit Windows operating system (Windows 98/ME/NT/2000/XP) as long as WinPcap capture driver is installed and works properly with your network adapter.

Under Windows 2000/XP (or greater), SmartSniff also allows you to capture TCP/IP packets without installing any capture driver, by using 'Raw Sockets' method. However, this capture method has some limitations and problems:

• Outgoing UDP and ICMP packets are not captured.
• On Windows XP SP1 outgoing packets are not captured at all - Thanks to Microsoft's bug that appeared in SP1 update... This bug was fixed on SP2 update, but under Vista, Microsoft returned back the outgoing packets bug of XP/SP1.
• On Windows Vista with SP1, only UDP packets are captured. TCP packets are not captured at all.

What's New in version 1.40:

• Added local/remote MAC addresses (relevant only for local network, and it doesn't work with raw sockets)
• Added IPNetInfo integration - When you put IPNetInfo utility in the same folder of SmartSniff, You can view the information about the remote IP addresses.
• Added IP Country columns to display the country name of IP addresses. (requires to download an external file from here)
