[Bug 350506] New: wireshark cannot resolve DNS names against IPv6 nameservers
https://bugzilla.novell.com/show_bug.cgi?id=350506 Summary: wireshark cannot resolve DNS names against IPv6 nameservers Product: openSUSE 10.3 Version: Final Platform: i586 OS/Version: openSUSE 10.3 Status: NEW Severity: Minor Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: dpantke@appriss.com QAContact: qa@suse.de Found By: Customer When using IPv6 nameservers in /etc/resolv.conf, I ran into some errors, and reverse DNS didn't work. The message was the following: adns: /etc/resolv.conf:12: invalid nameserver address `2001:5c0:94a9::1' Upon further investigation, it appears that the adns library has no IPv6 support in it at all. It cannot query IPv6 nameservers, and doesn't appear handle resolutions for IPv6, either. There are some IPv6 patches that have been out for quite some time, but it appears that with the general inactivity of the adns project this support is unlikely to be stable anytime in the near future. So, instead of waiting indefinitely, I have 2 options to alleviate this problem. 1. Disable concurrent requests by default. In this case full functionality should be preferred over performance 2. If the Wireshark code allows for it, when concurrent requests are enabled, only send the request to adns if the address family is IPv4. This is the best overall workaround, as it allows for the large majority of IPv4 users to use the faster resolver, while IPv6 folks will at least work. However, this will also require a smaller adns change to at least query IPv6 nameservers. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

From Wireshark folks:
I don't think that anything should be done in Wireshark, but if you feel like it then provide a patch to adns - either implementing ipv6 support or at least parsting the ipv6 statement and supressing that specific warning. In case the maintainer doesn't incorporate the patch then distributions should include it in their packages.
Patch for adns exists and is available here: http://www.chiark.greenend.org.uk/pipermail/adns-discuss/2007/001177.html Reassigning to adns maintainer. Marius, could you please decide whether you include mentioned patch in adns package or wait until upstream integrates it? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
