Bill,
#Actually an SMTP server sends packets full of data whereas Telnet
#sends one character in each data packet. This an easily detectable
#difference. Raptor generates a log entry when it detects this type
#of activity. I agree with you on the rejecting SMTP connection
#because they are Telnet connections. Seems pointless.
This used to be be true but for a while now telnet has a line at a time
mode. The mode used is negotiated at the start of the connection.
Half-Duplex - The original mode. Requires the GO Ahead command from the
server before accepting user input and is character at a time (I believe).
Character at a time - This came after half-duplex and is the type of
connection you are talking about. Each character is sent in it's own
packet.
Line at a time - This was the first implementation of line at a time.
Linemode - True line at a time, The specifications are in RFC1184.
Regards,
Jeffery Gieser
