soon, Navisys GR-701-W
Hi! I have just ordered a batch of the Navisys GR-701-W USB connected GPS receivers. They are probably at least 5 weeks from delivery to my hackerspace. When they arrive, I will ship some to some NTPsec people, and then put the rest up for sale as an electronics part up on Etsy and Tindie, probably for about $45/each. If I work out a good enough way to do it, I may have the NTPsec logo & url silkscreened onto the them. The GR-701-W provides only a USB interface, and so lacks the final precision of a PPS interface. OTOH, someone can just thoughtlessly plug one into a random PC or WRG, install gpsd, and have a good-enough compliant stratum 1 server. I decided not to at this time order a lot of the Navisys GR-701-T, which is a TTL interface with a PPS line. While this is a more precise source and easier for RasbPi/etc hobbyists, they are more likely to want to use the GPS receiver HAT and daughterboard units already easily available to them. ..m ___ devel mailing list devel@ntpsec.org http://lists.ntpsec.org/mailman/listinfo/devel

Finding abusive NTP clients
I just pushed a tweak to ntpq's mrulist command to provide more info if the average interval between requests is tiny. Anybody running a pool server might like to try it out. It now looks like this: ntpq> hostnames no ntpq> mru mincount=1000 sort=avgint Ctrl-C will stop MRU retrieval and display partial results.
