Description Ola Thoresen 2009-07-03 10:22:01 UTC

Description of problem:
After an update today xulrunner (at least both Firefox and Thunderbird) will not resolve any hostnames.  
After chnaging hostnames to IP-addresses for both SMTP and IMAP-servers in Thunderbird mail works again.
I can also browse websites with IP-addresses (IE http://195.159.1.4/) but any hostname just gives the error:
Server not found

Firefox can't find the server at www.powertech.no

tcpdump does not show any hostname-lookups at all (no traffic on port 53) and the problem is present both with nscd enabled and disabled, and after invalidating hosts in nscd.

Ping works fine, browsing with a non-xulrunner browser (Opera) works fine, ssh works fine, resolving hostnames via both "host", "nslookup" and "dig" works so it is NOT a network- or DNS-issue.  

Version-Release number of selected component (if applicable):

xulrunner-1.9.1-2.fc12.x86_64
firefox-3.5-1.fc12.x86_64
thunderbird-3.0-2.4.b3pre.hg.6a6386c16e98.fc11.x86_64

How reproducible:
Allways

Steps to Reproduce:
1. Open any website in firefox
2. Check or send mail with Thunderbird and hostnames (not IP-addresses) in the server-fields.
  
Actual results:
No connection

Expected results:
Well..

Additional info:
On a side-note, Thunderbird will actually _crash_ trying to send mail with a hostname as the smtp-server.  Changing to IP-address works fine.

You said its not a DNS issue , but please, indulge us. What does 
$ grep ^hosts /etc/nsswitch.conf
say?

Comment 2 Parag Nemade 2009-07-03 10:41:10 UTC

just look at how to fix this in bug 508481

Comment 3 Ola Thoresen 2009-07-03 11:32:22 UTC

What I meant with "not a dns-issues" is that my DNS-servers are wirking fine, and other applications (ping, ssh, opera ...) is able to resolve hosts.

But you are right. Installing nss-mdns-0.10-7.fc11.x86_64 fixed the problem.

Thanks.
