Hi Team, I am trying to install kdig utility in Linux fedora 8.8 but not successful. I took the reference from https://www.knot-resolver.cz/download/ Tried below: # yum install -y epel-release Oracle Linux 8 BaseOS Latest (x86_64) 4.7 kB/s | 3.6 kB 00:00 Oracle Linux 8 Application Stream (x86_64) 9.8 kB/s | 3.9 kB 00:00 Oracle Linux 8 CodeReady Builder (x86_64) - Unsupported 3.7 kB/s | 3.3 kB 00:00 ITE 20 kB/s | 1.4 kB 00:00 Package oracle-epel-release-el8-1.0-5.el8.x86_64 is already installed.

Problems with DNSSEC .CZ

by Martin Doubrava

Hi colleagues, we are using knot-resolver as anycast resolvers for our region wide network. Everything works fine, but from saturday we are experiencing problems with zone .cz on one of our resolvers: lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [plan ][00000.00] plan 'www.seznam.cz.' type 'AAAA' uid [20220.00] lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [iterat][20220.00] 'www.seznam.cz.' type 'AAAA' new uid was assigned .01, parent uid .00 lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [cache ][20220.01] => skipping exact RR: rank 060 (min. 030), new TTL -16225 lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [cache ][20220.01] => trying zone: seznam.cz., NSEC3, hash db928b48 lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [cache ][20220.01] => NSEC3 depth 1: hash 0sil3tll31qpi1iq50o2h3kjrmon169q lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [cache ][20220.01] => NSEC3 encloser error for www.seznam.cz.: range search found stale or insecure entry lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [cache ][20220.01] => NSEC3 depth 0: hash lg5rgspgqdoqqjko0u7fkpkakk8hgc1s lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [cache ][20220.01] => NSEC3 encloser error for seznam.cz.: range search found stale or insecure entry lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [cache ][20220.01] => trying zone: seznam.cz., NSEC3, hash f8ba757c lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [cache ][20220.01] => NSEC3 depth 1: hash s92e2vuk6k14pvqp4ubga1im9kpgff8a lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [cache ][20220.01] => NSEC3 encloser error for www.seznam.cz.: range search found stale or insecure entry lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [cache ][20220.01] => NSEC3 depth 0: hash 07u4nbhjigung96jklsqvtf6crqjojp8 lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [cache ][20220.01] => NSEC3 encloser error for seznam.cz.: range search found stale or insecure entry lis 27 12:44:19 doubrava-dns-lito-02 kresd[9742]: [zoncut][20220.01] found cut: cz.

Other machines are working seamlessly. What we are doing here wrong? Thank you! -- Best regards Bc. Martin Doubrava CEO _______________________________ DOUBRAVA.NET s.r.o.
