Lately I've been having problems accessing a few web pages, google.com in particular (ack!). For google and the others, any access to the website times out. I though the problem was with my Internet provider but when I just rebooted into windows I could access everything just fine.

I'm running a brand new gentoo installation so I'm thinking that I've screwed up something in the network settings but I'm not sure where the problem could be.

I can resolve website addresses just fine. I can ping www.google.com and have 100% return. I have my hostname set to localhost, hosts file just has the 127.0.0.1 localhost setting. I use a cable router setup to DHCP that has never given me any trouble.

Any ideas?

You could have ecn turned on, not all routers on the internet support it yet.
to check
Code:

cat /proc/sys/net/ipv4/tcp_ecn

To turn it off (if the above returned 1)
Code:

echo "0" > /proc/sys/net/ipv4/tcp_evn


You can also be having MTU issues - see http://www.netheaven.com/pmtu.html or https://forums.gentoo.org/viewtopic.php?t=93381 for some details.

Arg! Thanks for the suggestions, but neither panned out. Ecn wasn't (and isn't) turned on, and I set mtu to 1024 but still had no access to google.com.

The affected websites that I've noticed are: *.google.com and
ncsu.edu. I didn't realize how integral google is to my browsing experience until I am no longer able to access it! :(

I am running a new box with the Asus P4P800-Deluxe motherboard (problems of its own there!). But I have the gigabit ethernet adapter working correctly with the sk98lin module.

All websites do resolve correctly in windows2000 and on my wife's iBook.

Older versions of the sk98lin driver had problems

e.g. see here: http://www.linuxquestions.org/questions/history/77189 or here http://www.linuxquestions.org/questions/archive/18/2003/07/3/70621.

I couldn't tell from the articles if there is a fixed up version or not
