      What were you trying to do that didn't work?

      set up STUB server with zone files from https://issues.redhat.com/browse/RHEL-106784

      Please provide the package NVR for which the bug is seen:

      bind-9.18.33-10.el10_1

      rhel10 / fedora

      How reproducible is this bug?:

      always

      Steps to reproduce

      1.  have a 1mintip machine
      2.  cd /mnt/qa/scratch/psklenar/stub, its mounted in 1mt or http://nest.test.redhat.com/mnt/qa/scratch/psklenar/stub/
      3. ./runtest.sh
      4. MASTER = running at port 53
      5. STUB = running at port 853
      6. see that STUB server works, look at log in /tmp/bind-for-petr/named.conf.STUB.log
      7. see it works by dig @localhost -p 853 NS petr.god
      8. ----look at logs in /tmp/bind-for-petr , for both stub and master, all seems to be OK
      9. use it with zones test-13 or test-18, already copied in /tmp/bind-for-petr by runtest.shfrom step 3.
      10. dig @localhost -p 53 NS 13a.test ;;;it works fine, port 53 is bind MASTER
      11. dig @localhost -p 853 NS 13a.test; timeout

      I tried also with more IPs, by

       

      ip a
      ip addr add 192.168.122.123/24 dev eth0
      ip link set dev eth0 up
      ip addr show dev eth0
      ip addr add 192.168.122.124/24 dev eth0
      ip addr show dev eth0
      ping 192.168.122.123
      ping 192.168.122.124
