Description Pavel Šimerda (pavlix) 2015-01-13 13:49:24 UTC
I have just tried to use dnssec-trigger in a partially blocked DNS. It is easy ti simulate by blocking udp and tcp port 53 on IPv4 but not on IPv6 or vice versa.


    device=...

    for proto in udp tcp; do $command -A OUTPUT -o $device --proto $proto --dport 53 -j REJECT; done

In this case dnssec-trigger didn't detect that direct DNS is (partially) blocked and concluded that it is fully usable. As a result, only some names could be resolved while others could not.

Comment 2 Fedora End Of Life 2016-07-19 19:04:48 UTC
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Changing version to '25'.

Comment 4 Pavel Šimerda (pavlix) 2016-08-24 12:10:49 UTC
I'm no longer sure why I filed this ticket as DNS servers should generally answer any requests whether they are on IPv4 or IPv6.
