A fair amount of info on a Raspberry Pi based solution can be found at <http://satsignal.eu/ntp/Raspberry-Pi-NTP.html> I have been running something based on this for the last year or so, and all I can say is 'it works for me'. Be sure to include some form of external RTC though. -d _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
