Symmetricom TimeSource 3000. It's an older, end-of-life model that we've had in place for a while. We have four of them in different sites, but this is the only one with a server with NTP hooked up to it. If I can (at least somewhat) rule out the ntpd PPS driver as the issue (by testing with ntp2), a next step is likely going to be configuring an additional server temporarily and placing it in one of the other sites on a similar TimeSource 3000. If that's good, then I can swap units to see if the problem follows the unit or the antenna. If the problem follows the antenna, then we have the question of whether it is a bad antenna or bad antenna placement. I may be stuck until spring, as the problem is likely bad enough to justify someone going on the roof in the cold to swap the antenna. -- Richard _______________________________________________ devel mailing list devel@ntpsec.org http://lists.ntpsec.org/mailman/listinfo/devel
