Hi ovirt
Recently, my samba internal dns has been getting a lot of errors, like:
[2020/12/02 15:24:31.484073, 1]
../../source4/dns_server/dns_query.c:1141(dns_server_process_query_got_auth)
dns_server_process_query_got_auth: Failed to add SOA record:
WERR_DNS_ERROR_RCODE_FORMAT_ERROR
I found that my ovirt nodes was sending a lot of strange requests, I use
tcpdump and got some like:
tcpdump -i ovirtmgmt udp port 53
17:00:23.875038 IP ovirt1.adagene.cn.53862 > dc1.mydomain.com.domain:
35727+ [1au] NS? . (40)
17:00:24.436466 IP 192.168.49.195.domain > ovirt1.mydomain.com.33625:
8887 FormErr-$ 0/0/1 (40)
about one request in a second.
And I noticed that some nodes which version is 4.4.2 did't send dns
requests like above. therefore no error occured.
Were there any recent changes to ovirt node that caused these errors?
