View Full Version : Crazy DNS problem

September 6th, 2010, 03:20 AM
Hello everyone.

I been having this random dns problem, in Ubuntu 10.04 and in 10.10 it started about 2 weeks ago after (I believe) an update.

Basically when I go to a website randomly I get that the website I'm visiting is not available ("Oops! Google Chrome could not connect to ..." & "This webpage is not available.").

I tested with Chromium "7.0.515.0 (58587)" and Firefox minefield (4.0ish) and 3.6.9.

I did these 4 things already:


and this:

#disable ipv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

*disabling Chromium DNS pre-fetching

*using Google and OpenDNS servers.

But didn't improve, also no other computers in my network have the same problem. All computer wired to the same router.

I'm a software engineer that run out of ideas, please help me.

Thanks in advance.
