Whenever I browse any website, mozilla says
"Resolving www.google.com" and waits for about
15 seconds to resolve the host. I've disabled
ipv6 but the problem is still there. Also I've
checked the isp nameserver and they are fine.
Does anyone has the same problem?

I'm not sure what the problem is.

Presumably, your startup page is set to www.google.com. I have mine set
to my home directory.

I'm on slow dialup. Every time any browser goes to a new page (even if
its been there before) it has to resolve it. Very annoying.

If this is the problem, you could install a caching name server that
would give a faster response.

By any chance, have you switched ISPs recently? You may still have the
DNS addresses of the old ISP, so everytime it resolves an IP, it has to
go to an outside nameserver, causing very long resolution time.
Just an idea...

This sounds like it could be a couple of things that I have run into.

First, it could be an mDNS(multicast dns) problem. That gave me fits
for a while.

I cured it one by uninstalling avahi-daemon, as I don't have use any
software that relies on this function(I did this just to stop an
unnecessary daemon), and also editing my /etc/resolv.conf file so it
didn't contain a line that used the word "local". This word being in
resolv.conf is/was a bug in Avahi-daemon, IIRC, that caused all DNS
lookups to be run as mDNS lookups first, and then go to the nameserver
picked up through dhcp, or in /etc/network/interfaces if you're using
static ip addresses, when the mDNS queries finally time out.

Second was the ipv6 lookups. I fixed that by blacklisting the ipv6
module and all those extraneous dns queries disappeared.

The way I found the mDNS problem with extremely long url resolution
times was to start an ethereal/wireshark packet capture, and then fire
up my browser. That's when I found that all dns queries were going to
224.0.0.xxx (mDNS).

I think the bug is now fixed as I just reinstalled a laptop a few days
ago and I didn't have to make any changes in resolv.conf. DNS worked
correctly from the very first, and that hadn't happened with any Etch
installs I'd done in the last month or so.

Thanks Doug. Caching nameserver has done the trick. I've setup
bind9 to act as a caching nameserver. Now it is a lot faster. Thanks
to forum members for their .

With great regret, the problem has shown its ugly face
again. mozilla again shows: Resolving host www.google.com
and a delay. I didn't have any problem until yesterday
when it started.

No I didn't change my isp.

I'm using Debian Sarge and after looking into Synaptic,
have found that there is no Avahi-daemon on debian
Sarge(stable). Is there anything else I should do?

Make sure your /etc/resolv.conf is still has it's reference
to your cacheing nameserver. Did bind9 stop for some reason.

This seems like a problem I had.
I could go to any site *except* www.google.com, and various other
search engines. I thought there was some sort of conspiracy going
on. :-)

This was with lynx-ssl and wget, i.e
"wget http://www.google.com/search?q=hipcrime"

If I tried "lynx http://www.google.com" it would either just sit there
then time out or as per usual go to http://www.google.co.nz but then sit
there and time out. It also happened if I tried yahoo.com, altavista,
askjeeves. I couldn't search the net! Other sites were fine.

On the other machine running unstable, this problem didn't occur.

I was stumped.

I installed links, and eveything has been fine since.

Since this is a reasonably old laptop in the middle of being upgraded to
etch, I decided to wait and revisit it later. Although I think I prefer
links.

Thanks for bringing it up and hope you find a solution.
