If they were inclined to notice and react to such things, they would almost certainly not have the type of configuration problems that lead them to be abusive in the first place. Rather than shifting the load away from, say, the 75% of the servers that block abusive clients, the abusive clients would be much more likely to not get any time sources and therefore be more likely to fix their configurations. > Has there been any thought towards building a common group defense? I suspect that individual NTP server admins taking care of their own servers actually does help the common group. Actually, when I first started running the scripts to detect abusive clients, I found a lot of them. I contacted many of the worst, and that usually had positive results. Now a days, I've noticed that there just aren't that many one packet-per-second clients around any more. I still have a lot of 15s and 30s clients, but they aren't as bad (obviously). > While I'm here, another question. Wayne Schmitt's ntpscripts are great > for monitoring things.

What kind of things were you thinking of? -wayne _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
