💖 check-zone-expiration — the "how much time do my DNS records have left bestie" tool 💖

okay so this is a User Contributed Perl Documentation page, and it's for a little script called check-zone-expiration, aka the manual everyone abbreviates as CHECK-Z...PIRATION(1). it's giving DNS deadline tracker energy and honestly? we're obsessed. 🎀

✨ NAME ✨

check-zone-expiration — displays how long until a zone's records expire 🦋

🌸 SYNOPSIS 🌸



# check-zone-expiration dnssec-tools.org paypal.com dnssec-tools.org

will expire in 12 days, 17 hours, 7 minutes, 1 second

# check-zone-expiration -m 1123200 dnssec-tools.org paypal.com
paypal.com          will expire in 12 days, 17 hours, 6 minutes, 22
seconds

no cap, that's the whole vibe right there. 💅

🌈 DESCRIPTION 🌈

so the check-zone-exiration script (yes bestie, that's how it's spelled in the page, we don't edit the queen ✋) reports how long until a zone will expire. it does this by querying for the zone's (top level) RRSIG and then calculating how much time is left before the signatures will no longer be valid. then — and this is the fun part — it reports how much time is left in human readable form. 😭 so thoughtful. so main character.

and if you hand it the -m switch with a time argument (in seconds 🕐), it will only print output for zones that have less than that time left. like a lil filter, a vibe check, an "only speak up if it's urgent" situation. 🙈

🎀 OPTIONS 🎀

  • -m STRING, --minimum-reporting=STRING — Minimum reporting time, or else be silent for the zone 🤫 (fr fr, if the zone's got more time than this left, it says absolutely nothing)
