Unfortunately, no, because the TCP stacks on most systems don't use the disciplined clock provided by NTP for the timestamps. Instead they use a clock based directly on the RTC, which reveals a characteristic skew that is unique to each machine. If the stacks used the NTP-disciplined actual time of day, plus perhaps a randomizing factor to avoid revealing patterns, this technique would become useless. -- Anthony _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
