Hi there, -advocacy, the well known german IT magazine "c't" has an article about a paper from Steven Bellovin called "A Technique for Counting NATted Hosts". The paper is about how to find out how many hosts are behind a NAT box, and the technique uses the IP ID field. The paper also states that "recent versions of OpenBSD and some versions of FreeBSD use a pseudo-random number generator for the IPid field" and thus it's harder to track down these OSes. The last paragraph of the german article is quite good for us, as it's says something like (sorry for probably bad translation :-): "The only sure method against this algorithm is to use LAN clients that generate random IP ids. FreeBSD and OpenBSD are some of the more useful representatives of this class..." It's online at <http://www.heise.de/ct/03/05/050/>. best regards, le --=20 Lukas Ertl eMail: l.ertl@univie.ac.at UNIX-Systemadministrator Tel.: (+43 1) 4277-14073 Zentraler Informatikdienst (ZID) Fax.: (+43 1) 4277-9140 der Universit=E4t Wien http://mailbox.univie.ac.at/~le/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-advocacy" in the body of the message
