Let's wind this thing back a couple of messages. Gibson's argument was that ICMP echo requests on raw (Unix) sockets were not possible with Windows 98 and below, since raw sockets weren't implemented on these OSs. So Microsoft fudged ICMP requests with (either UDP or) TCP. In as much as you have to be root to use raw sockets (try a ping on, for example, a BSD machine without being root), introducing the concept of raw sockets in XP constituted a security risk. There was an extremely long article about this about a year ago, but it's now disappeared. An example of a non-root Unix user wanting to ping, is that he uses hping2, which uses UDP/TCP fudges. This is neither an anti-Gibson nor an anti-OS posting. What it is, is an attempt to clarify iptables rules. I'm a Unix security bod in the widest sense of the word and very interested in all security aspects. This is merely one, but it would be nice to get it cleared up. > http://www.grc.com/ That was the one, yes. Just grc.com works too.
