If you're going to just wade into that without understanding how NTP actually detects a falseticker, good luck. If you only have 4 NTP servers, you're not going to have much luck if you have 2 outliers. IIRC you need 2n+1 servers to detect n bad servers _______________________________________________ Tech mailing list Tech@lists.lopsa.org https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
