Topic: using nsupdate to create TXT records for letsencrypt and DKIM
Hello.I'm trying to automate letsencrypt cert creation via dnsThis is what I'm sending to nsupdate: server api.dynu.com zone example.com update add _acme-challenge.example.com 30 IN TXT "blahblahblah" key hmac-md5:example.com ==SomeRandomTokenValue== send quitit is returning success. My TSIG token is recent and valid. rc=0My problem is that when I query dns via dig/nslookup/web-site the record is not there. I also don't see any updates in any of the logs that I've found at dynu.com.Does anybody have any experience with this? Is something missing from somewhere?
