That makes sense. I left sig-validity-interval at its default (30 days) and from October 19 to November 11 (the dates of the files) there are 23 days, while 30 * (1 - 1/4) = 22.5. Looking closer, I realized that the next day signature was not rewritten in the same view. Perhaps the jitter can be cured by setting a multiple of 4 as the validity interval... Thank you for the detailed explanation Ale -- _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
