[Bug 1228955] Re: dnsmasq changeds virtualbox guests PTR queries into A queries
Hi Thomas, Because when I disable dnsmasq from NetworkManager config, and I get the my regular DNS server into resolv.conf (of my host), the Virtualbox guests behave normal. so I thought if the issue occurs with dnsmasq, and doesn't occur without it, then it's dnsmasq's fault and not Virtualbox (which can't really know if dnsmasq is even used or not). -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1228955 Title: dnsmasq changeds virtualbox guests PTR queries into A queries To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1228955/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1228955] Re: dnsmasq changeds virtualbox guests PTR queries into A queries
Hi Thomas, This is indeed not a dnsmasq issue. It is Virtualbox, turning PTR queries into A queries when the name server on the host's resolv.conf file is from 127.0.0.0/8 segment. I'm still investigating why. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1228955 Title: dnsmasq changeds virtualbox guests PTR queries into A queries To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1228955/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 1228955] Re: dnsmasq changeds virtualbox guests PTR queries into A queries
Sorry for the double-post. I believe this is the code that is causing Virtualbox to behave like this: https://www.virtualbox.org/browser/vbox/trunk/src/VBox/Devices/Network/slirp/slirp_dns.c#L283 I don't have any idea why it is there, but it says that it's specifically for modern Ubuntu releases which have 127.0.1.1 as the name server (Network-Manager-managed dnsmasq...)

[Bug 1228955] [NEW] dnsmasq changeds virtualbox guests PTR queries into A queries
Public bug reported: Hello, For some reason, when trying to resolve a PTR query (host -t PTR 8.8.8.8 for example) from a VirtualBox guest (Doesn't matter which OS), the resulting query on the host (Ubuntu 12.10) eth0 on wireshark is an A query for 8.8.8.8.in-addr.arpa, which of course fails. This happens for all PTR queries, public and private. When I stop using dnsmasq in my host (by commenting it out on /etc/NetworkManager/NetworkManager.conf), everything works as expected. I know this is not a VirtualBox issue. Resolving the same PTR queries exactly (with the same 'host' utility) on the host works great.
