Are you trying to detect it in real time, or collect long term data? Turn on rawstats. (info in monopt.html) That will log 4 time stamps for each ntp packet received. If the time on both systems is accurate, that will give you a pair of one-way times. ntp tries to filter out the packets with long (queueing) delays so you will see the bad stuff in rawstats that you won't see in peerstats or ntpq -peers -- These are my opinions, not necessarily my employer's. I hate spam. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
