As the summary says, pretty much. The built-in DNS server (as given to us by classicupgrade) listens on all of our external IPv4 and IPv6 interfaces, but not 127.0.0.1 and ::1. It probably should.
Thanks for reporting this bug. I'm working on a fix for rc2.
Kai, some time ago I made an attempt on fixing this: http://repo.or.cz/w/Samba/mdw.git/commitdiff/7aee4a4a8f76d74235b2f8a064e581dd0f143f4a I do not know how correct it is but it could be useful.
Thanks for the patch, Matthias. I've just pushed this to my repo and will push to autobuild later today.
Should be fixed in current master by 5f973631b6ba6666ecf5f026d07dded9da15650e, I'll prepare a patch for 4.0-test as well.
Created attachment 7935 [details] Patch for v4-0-test Matthias' patch, based off v-4-0-test.
Comment on attachment 7935 [details] Patch for v4-0-test Looks reasonable to me.
Karolin, please pick for RC2
Pushed to autobuild-v4-0-test. Closing out bug report. Thanks!
