Talk:TCP/IP stack fingerprinting

From Wikipedia, the free encyclopedia

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)

[edit] 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)

[edit] 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)
