I have noticed 11 clients making consistent NTP requests to a public time server of mine at a rate of one request every 2 seconds, all from this netblock. For the time being, I now respond to time requests from your netblock with ICMP Admin Prohibited packets. I assume that many other hosts in your range of allocated addresses are configured to use public NTP pool servers, and also request at this very high rate of traffic. Properly configured NTP clients should not request more than once per minute at the lowest threshold, and over 15 minutes or higher when properly synched to another clock.
Please review your configuration for NTP services. Given the number of hosts you likely run from this address, I also recommend having only 2 machines which query to the outside world, and the rest of your machines querying from those two. Thank you for your time, Amazon.com -Jeff SIG: HUP _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
