Description Thomas Janssen 2009-07-02 08:43:06 EDT
Description of problem:
The nss-mdns from updates-testing 0.10-6 for x86_64 breaks the local name resolution. Internet in general was working, since i was able to download the 0.10-5 from koji within a VM on that box and downgrade it.

For example: host google.com    was working.

Version-Release number of selected component (if applicable):
nss-mdns 0.10-6 x86_64

How reproducible:
Install nss-mdns from updates-testing

Actual results:
local name resolution broken, no browsing

Expected results:
Everything working.

This sounds close enough to what I am seeing, that I'll add to this bug rather than create a new one.
wine now pulls in nss-mdns which had me install it when I previously didn't. This broke dns lookups for some applications and not others. For example ssh, firefox, and cups were broken. nslookup continued to work.
The version I installed was 0.10-7.fc11. Removing it fixed things up.
I run a local resolver (dnscache) on as specified in /etc/resolv.conf.
In order to affect a change a package needed to be restarted. For example after firefox was broken, uninstalling nss-mdns did not immediately fix it. I needed to restart it to get things working. For these apps, using IP addresses worked so it appears that dns resolution is waht was broken. I didn't see any logs for dnscache for attempted lookups when things were broken.
Comment 2 Bruno Wolff III 2009-07-03 16:17:14 EDT
What I am seeing might be a multilib dependency issue. I saw a comment on the wine bodhi feedback, that suggests that having nss-mdns.i586 installed, without having nss-mdns.x86_64 installed, breaks things.
Comment 3 Thomas Janssen 2009-07-05 01:45:20 EDT
Cant copy that. I had nss-mdns x86_64 installed. Because of wine, the x86 package got installed. Everything was still working. Next a bunch of updates from updates-testing was installed and it was broken.
5 Minutes of checking what could have broke it showed that the nss-mdns package was the suspect. Downgrading it fixed it. Sorry.

Forget my part on this bugreport. Bruno Wolff III is totally right with the multilib issue.
I confused two packages and a repository. My bad. Sorry. Totally a shame.

It was that wine installed nss-mdns.i386 on F10 and to install the x86_64 nss-mdns fixed it. I run the latest package flawless.

Again, sorry.
