UCS 4.2: short/unqualified SRV dns queries don't work any more
Last modified: 2020-07-03 20:51:35 CEST
UCS 4.1: root@master10:~# dig @localhost _kerberos._tcp SRV +search +short 0 100 88 master10.ar41i1.qa. root@master10:~# host -t srv _kerberos._tcp _kerberos._tcp.ar41i1.qa has SRV record 0 100 88 master10.ar41i1.qa. UCS 4.2: root@master10:~# dig @localhost _kerberos._tcp SRV +search +short root@master100:~# host -t srv _kerberos._tcp Host _kerberos._tcp not found: 3(NXDOMAIN) root@master100:~# host -t srv _kerberos._tcp.$(dnsdomainname) _kerberos._tcp.ar42ms2xi1.qa has SRV record 0 100 88 backup101.ar42ms2xi1.qa. _kerberos._tcp.ar42ms2xi1.qa has SRV record 0 100 88 master100.ar42ms2xi1.qa. I tested with dns/backend=samba4. Adding "search" to resolv.conf doesn't help.
Same with dns/backend=ldap
It works for normal host records, just not e.g. for SRV records. apt-get install \ bind9-host=1:9.8.4.dfsg.P1-6+nmu2.124.201610152034 \ dnsutils=1:9.8.4.dfsg.P1-6+nmu2.124.201610152034 and it works again. No clue why yet.
I don't think it is a blocker for the release. Please change the target milestone, if someone disagrees.
It seems to be a problem on our member servers as well. At least it is shown as problem in Jenkins: I've adjusted the system check test: r80603: * dns/forward_and_reverse_dns_myself.sh: Skip short dsn query on member server (Bug #43854)
