We have GPS receivers in the machine room that supply clock for some of the transmission network, but when I ask the telco guys about the output of these receivers they just frown confusedly and say "it's a 2 meg clock". I haven't mentioned NTP, because I can't be bothered to spell it for them :) So, we have an RF GPS source in the next rack which we can split and run into our racks on coax. What kind of receiver do we need to provide a synch source for xntpd to chime off? We have Ultra 2s and x86/FreeBSD boxes available which are running xntpd, but which are currently chiming of stratum-2 sources on the other side of the planet, which just seems sub-optimal :) Joe To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
