I have experienced a strange problem with xntp 1.4 on our local Sun workstations (Sun-3 and Sun-4 with SunOS 4.1 and SunOS 4.1.1). When xntpd is started, the `peers' command of xntpdc lists a dispersion of 63.5 or 64.0 for all peers. Then the dispersions increase by a factor of 2 after each polling interval. When the dispersion listed for a peer sinks below a certain threshold, xntpd synchronizes to this peer, i.e. its name in the `peers' listing is prefixed with `*', and all others are prefixed with `+'. So far everything looks fine. Now the strange thing-- `poll' seconds after the local machine has synchronized to a peer, all dispersions start over with a value of 63.5 or 64.0 again, and the synchronization is (therefore) lost. This cycle repeats ad infinitum. I have tried several peers with different strata (from stratum 1 to stratum 3) without success. Is this normal? If not, where should I start looking for a problem? By the way, tickadj reports a hz value of 100, tickdj is 5us, and dosynctodr is off. Regards, -- Oliver Laumann net@tub.cs.tu-berlin.de net@tub.UUCP
