Ubuntu

I can only browse GOOGLE and some other few sites.

Asked by R.Costa

Hi, I am using the 7.04 install on a AMD64, dual boot with Windows.
The configuration IP config of Linux is the similar to the Win(that works perfectly) config, fixed IP, gateway and DNS provided by the ISP.

The problem is:
-Using firefox I can browse google.com (and all its sibling sites, gmail, news, etc), but the result pages does not open.
-I can access www.ibm.com.
-I cannot access yahoo, aol and 99,99% of the other pages that I tried.

What I've tried (and additional info):
- I disabled IPv6 in firefox and in the system using all the tips that I could find on the internet.
- Ping works OK to site IP and site names ( eg: ping www.yahoo.com -->OK)
- wget www.google.com -> OK
- wget www.yahoo.com --> keeps trying forever. (with this results it does not looks to be a firefox specific problem)
- Although it does not look to be a DNS problem I tried diferent DNS' IPs, including OpenDNS.

Any info or tip are strongly appreciated since this problem is taking my sleep away already.
THANKS!

Thanks for your question. Can you go to sites by using their IP addresses - f. ex. is there any difference if you surf to http://www.kserver.dy.fi (my home server) or http://81.197.49.75 (its IP address)?

Terve Riku ! Thanks for the fast reply.

Unfortunately there is not a difference, it does not matter if I use the name or IP address, on the most sites none work, on few sites (google,ibm) both work.

Best Regards.

Hi All.

I finally managed to find the solution for this problem.
Changing the MTU of the interface to 1492 solved the problem completely.

sudo ifconfig eth1 MTU 1492

"the more I know, the less I know" ...

Cheers.
