[SOLVED] Google only browsing

timktaylor · 10-01-2009, 05:07 PM

This is a puzzler.

I have a new install that I cannot get web access working. I have a shared broadband connection routed through a router that five other Windows machines are share just fine. I get an IP address via DHCP just fine but from at least two different browsers, I get the following behavior:

google.com comes up quickly and reliably.
google search results come up quickly and reliably.
Almost nothing else works. Clicking on any search results (that aren't provided by google) just hangs.
A few select sites do work, though somewhat slow (e.g. ibm.com, mit.edu, vanderbilt.edu, several *.edu that I have tried, but not all, even redhat by its IP address only!!!)

Any idea what would cause this behavior?

I have disabled:

Firewall
IPv6
SELinux

Insights, guesses, and suggestions welcome.

regards,
tt

Tim,

A similar problem I encountered a while ago was caused by DNS.
Try to ping some funky site that doesn't want to work at all and see if it resolves it.
The solution may depend on your setup and distribution or the ability of the gateway to pass through DNS.

You may want to post some details of your setup.

Code:

# cat /etc/resolv.conf

compare that with what Windows provides as the DNS Server IP Address.

Pinging an unknown host did not help.

Same nameservers in Windows machines. In fact they are working with just one. I added the other from my ISP trying to fix to no avail.

I am running Fedora 11.

Code:

nslookup linuxquestions.org 4.2.2.1

Report back.

timktaylor · 10-01-2009, 08:08 PM

Server: 4.2.2.1
Address: 4.2.2.1#53

Non-authoritative answer:
Name: linuxquestions.org

One other tidbit: my router does not pick up my Linux hostname.

Hm.. I believe the router has some kind of a dns forwarder that doesn't work. However it has cached google's ip. When TTL ends, i THINK google should stop working too.

Besides, have you tried opening any webpage on their IP?

If they DO open with IP, it just must be a name resolving problem. You should either change your DNS server, or reconfigure the router

tapke,

In regard to the question "any webpage on their [my ISP, I assume] IP?"

I just tried to go to www.comcast.net, first on a Windows machine, and it came up with lots of media, etc., then I tried on my Linux box and was taken to an error page which said:

Quote:

Sorry, we can't find "http". We suggest that you check the spelling of the web address or search above.

I entered http://www.comcast.net into the address bar in both cases on firefox. My Linux Opera just hung like other sites.

My DNS Suffix search list is hsd1.in.comcast.net.

This is what it seems like is going on. Name resolution is not functioning properly. What is the content of your /etc/resolv.conf ?

Try adding a line to it that looks like:
nameserver 4.2.2.1

Then see if it works. Your resolve.conf is auto-created though, so the changes will be temporary. If this solves your problem, then it is a error in your router configuration. Find out how to set nameservers in your router.

Here is more info:

Setting 4.2.2.1 as only nameserver does not help. Same behavior.
I can surf to certain IP's only; just as I can surf to certain sites only (ibm.com, google.com, mit.edu, vanderbilt.edu, etc)
I can go to http://209.132.177.50/ solidly but not to http://redhat.com or http://www.redhat.com
No other PC on my network has this issue. There are 2 Win2k, and three WinXP also local
I have downloaded and booted with the LiveCD and tried to surf with it; same problem exists on the system I am experiencing the problem (Fedora Core 11 new install).
I booted the LiveCD on one of my Win2K machines and surfing works!

Now this says to me perhaps my NIC? What flaky? I can run wire shark and the spotty site access mentioned above; I don't think so.

Theories?

Did you disabled ipv6 in the browser?
about:config
set
network.dns.disableipv6
to true

timktaylor · 10-03-2009, 03:25 PM

Yes, I did.

Hi together,

if there is an issue with your nic or with a cable I'd suggest to ping another computer within your network and then ping your Linux-machine from the other computer. Find out, if there is a difference between both directions.

Markus,

I can ping only the router and other wired local systems and they can ping my fedora box, as well. Can't ping wireless connected systems. Wireless workstations can only ping wired systems, as well, and the router. No system can ping my local wireless IP's.

Does that sound related?

My router is a 5-port + wireless access point.
