Paul, Just for interest, the ntpd.conf for my PC Narvik contains lines like: _______________________________________ server 192.168.0.2 iburst maxpoll 6 prefer server 192.168.0.7 maxpoll 6 server 0.uk.pool.ntp.org minpoll 10 server 1.uk.pool.ntp.org minpoll 10 server 0.europe.pool.ntp.org minpoll 10 server 1.europe.pool.ntp.org minpoll 10 _______________________________________ The first two are my local stratum-1 servers (GPS/PPS to Windows XP systems, ideally with a light or relatively constant load), and are set for 64s polling (maxpoll 6). To avoid hitting the Internet servers with requests as often, they are set for minpoll 10 (1024s), as they are for backup in the case that both my stratum-1 servers fail. A direct connection from the serial GPS/PPS puck is the best, but even if you need to go through a serial-USB convertor performance may be adequate (I saw about 160us jitter). Cheers, David _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
