SmartSniff allows you to capture TCPIP packets that pass through your network adapter and view the captured data as sequence of conversations between clients and servers. You can view the TCPIP 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 2 methods for capturing TCPIP packets : * Raw Sockets (Only for Windows 2000XP or greater): Allows you to capture TCPIP packets on your network without installing a capture driver. This method has some limitations and problems. * WinPcap Capture Driver: Allows you to capture TCPIP packets on all Windows operating systems. (Windows 98MENT2000XP2003) 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 TCPIP packets with SmartSniff and it works better than the Raw Sockets method.
