Public bug reported:
Binary package hint: squid3
Firefox queries go to the wrong DNS server.
Now, the reason I have logged this against Squid is because of the way
in which I solve the problem.
I switch on my laptop, which has a Squid local cache, and it boots normally.
I log in and open various programs.
Both Firefox and Empathy, which connect via the proxy (although I don't
want Empathy to, but that's another problem), and start sending DNS
queries to 192.168.0.2. 0.2 is the correct address for my home router,
at work the address is 192.168.1.1. Now, when I go home it queries 1.1
when it should be querying 0.2.
Netrik and apt-get use the correct DNS, even though they go through the
proxy. Everything else uses the correct DNS server.
The solution is to restart Squid. Everything now queries the correct
DNS.
>From Squid's cache.log:
2011/03/29 16:58:21| Adding nameserver 192.168.0.2 from /etc/resolv.conf
After restart:
2011/03/29 17:16:27| Adding nameserver 192.168.1.1 from /etc/resolv.conf
Presumably other apps are gaining DNS details themselves, but Empathy
and Firefox are relying on Squid, which fails to pick up the change in
resolv.conf until it is restarted. This is a real pain.
