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)
