A happy ":)" could be replaced with a frown by a malicious attacker, by using a winking eye ";(". This could misrepresent the intended mood of the sender to the receiver. Don't you hate it when your packets are misrepresented surprised when you mean for them to be silly. On Sat, Apr 3, 2010 at 9:19 AM, Dan Burrowes <danburrowes at gmail.com> wrote:
I was browsing some RFCs and it looks like this was just added. ?Highly recommended read for the weekend: "TCP Option to Denote Packet Mood" http://www.rfc-editor.org/rfc/rfc5841.txt It ranks right up there with RFC 1149, "IP Datagrams on Avian Carriers". --dan _______________________________________________ Pauldotcom mailing list Pauldotcom at mail.pauldotcom.com http://mail.pauldotcom.com/cgi-bin/mailman/listinfo/pauldotcom Main Web Site: http://pauldotcom.com
