Hey all, I apologize in advance for sending multiple messages to the list... I've recently "graduated" from inattentively keeping my server in the pool to actively monitoring two servers in the pool, and have some questions as a result.
I've noticed 8.8.38.2 syncing to me every 32 seconds. I wouldn't have thought too much of it, but the IP just looked "odd" (actually, even....) and thus caught my eye. By dumb luck, I wound up looking at access stats for some of the servers in the pool that provide online stats, trying to see what sort of loads I'd get if I increased my bandwidth on the pool. And I saw the stats on ntp.dayww.net... Where 8.8.38.2 is seemingly querying every 500ms. So I tried Googling the IP, and found that it shows up every 32 seconds on Wayne Schlitt's server as well. So now I'm left wondering how many of us it's affecting. It seems improbable to me that it's only syncing to the three of us, and I happen to have viewed the access stats of each today. I'm wondering if it's syncing to a huge number of hosts. The IP appears to be registered to omniti.com; edge.omniti.com is 8.8.38.6. I wondered if there existed a good tutorial online that told people how to investigate and fix their NTP problems. I'm assuming that most of these abusive clients are the results of people who don't know how to configure NTP, and thus, even though it's their duty to fix their abusive clients, they probably would have no idea how. It'd be very helpful if there were a good tutorial, so I could just e-mail them, mention the problem, and point them at the tutorial. Jeffrey Goldberg has a good page at http://www.goldmark.org/netrants/ntp-abuse/ but it doesn't really address *how* a clueless admin can fix their servers. All of this got me thinking about something else... I've created a few small MediaWiki installs for various groups. Would there be interest in a "NTP Pool Wiki" type thing? I've got a webserver with the space if needed. (I'm aware of the support.ntp.org site, but haven't found it overly useful. I'd be more interested in a site about the pool, and maybe about configuring ntpd.) It seems that this mailing list is home to some of the people most-knowledgeable about NTP. I just don't want to create something that no one will use. (Nor do I want to step on toes if such a site exists and I've missed it!) -- Matt _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
