But it is possible to use ntpd to monitor a list of servers without severely impacting their performance (by using noselect and increasing maxpoll and minpoll) >From this list one can evaluate server performance and remove ones that have high delay (>60 for my standard) and high jitter (>20 for my standard again). _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
