There was some correspondence last year about this warning message, but this seems to be caused by something new.
Since 2011-09-02 we have been seeing messages like this Sep 22 16:38:52 authdns1.csx.cam.ac.uk named[646]: dnssec: warning: client 149.20.58.131#52557: expected covering NSEC3, got an exact match on both our main authoritative-only (recursion no) nameservers. Our own zones don't use NSEC3, but we do officially slave two that do (srcf.net and srcf.ucam.org) so I have been assuming that they are responsible in some way. But we didn't change anything in the server configuration at the time the messages started, and the zone administrator (hi, Malcolm!) says the same about the contents of the two zones. We were running BIND 9.7.4 at that stage, but upgrading to 9.8.1 hasn't caused the messages to go away, as I had rather hoped. Has anyone any clues about this one? Or observed anything similar? -- Chris Thompson Email: c...@cam.ac.uk _______________________________________________ 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
