Talk:TCP/IP stack fingerprinting

The article says that banner grabbing is only possible for the protocols FTP, TELNET and HTTP. I'm sure that the list is incomplete, because it is although possible to find out the banner from an SSH server via netcat, which doesn't use any of the three protocols above. --Gronau 20:10, 8 July 2007 (UTC)

Wrong Title
The page is called 'TCP/IP stack fingerprinting', but starts with an explanation of OS fingerprinting; in fact, the phrase of the title does not appear in the article at all. This is obviously wrong. How to fix? No clue here. Eaglizard 06:03, 15 April 2007 (UTC)

blocking ICMP echo reply
The article suggests to block all outgoing ICMP echo replies, but I've read somewhere that a RFC requires every computer to respond with echo reply to an echo request. is it true? --grawity (talk) 21:09, 25 November 2007 (UTC)

diagram
How does the diagram illustrate in any way anything about fingerprinting and how is an active fingerprinter different than this diagram for passive fingerprinting? I would suggest removal of this image. Kbrose (talk) 19:24, 7 September 2008 (UTC)
