Weird, random errors when browsing web

futuremonkey · 2010-04-04 01:30:13

I have Arch on a laptop at work. It connects (wired) to a network. A while back, I started getting random errors when browsing the web. They happen whether I'm using Firefox, Chrome, or Opera.

I get things like:
404's on Google.com, yahoo.com

Invalid URL with any url ending in a "/"

The requested URL "(WEBSITE URL HERE)", is invalid.
Reference #9.46b1160.1259175976.28ae33f"

(THIS # CHANGES EACH TIME)

Sometimes, I get randomly redirected to the Windows Update site (!) and Myspace, which I also ever use.

It has to be something going on with the laptop, because no other machine on the network has the problem. It smells like some kind of proxy thing going on. I don't remember ever installing any sort of proxy software on it...

Any ideas where I should start looking?

Hi,

Couple of things, it might be a good idea to install a rootkit hunter just to see if you have accidentally downloaded something nasty-you could use chkrootkit or rkhunter-rkhunter is good. It's a bit of work but these things are all trial and error.

Do a 'ps aux' in a terminal to see if anything is running that looks like a proxy, is it possible that someone has got into your computer and installed something?

Late April fools day joke? If not... ooops ; I'd try as suggested above. This is certainly weird as it's the first time I've come across it.

Sadly, not a joke. I used rkhunter and got the false positive as described here; chkrootkit came up with nothing.

ps aux doesn't reveal anything odd, either.

Try changing the dns to opendns. Could be the ISP doing something fishy with redirects.

Have tried the ISPs DNS, OpenDNS, and Google's DNS - all with the same result. I'm pretty sure the problem is only on this machine. Oh well.

Others having the same problem here, so it's not something exclusively Arch-related. Very frustrating!

futuremonkey,

try disabling ipv6:

Also try enabling "options single-request" in resolv.conf:

echo "options single-request" >> /etc/resolv.conf.head

Just my 2 cents.
