for my own zones i think i'm using one year signatures and regenerating them from "cron" once per week -- just to be safe. so, not better discipline unless you deliberately _live_ on the edge, which i think is an unwise practice. i expect i'll crib together some bourne shellack to check my whole signature chains and warn me when there's less than 72 hours remaining in any validity period. going into SERVFAIL like this is an operational risk i shouldn't take. -- Paul Vixie _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations
