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-based protocols, like DNS).
[advt]SmartSniff is able to capture TCP/IP packets using raw sockets. This method has some limitations and problems, but it does not require any additional installation. This works on Windows 98/ME/NT/2000/XP/2003, and functions better than the “raw sockets” method
