Color me dumbfounded. Disabling TCP timestamps actually allows me
to connect to Google. Reenabling them re-introduces the problem.<br>
<br>
The only question still remaining is "why"? I have up on the site
two captures. One of the working session, and one of the not
working session. To me, this still looks like a kernel bug.<br>
<br>
Get them:<br>

Ideas, anyone?<br>

Hi all,<br>
<br>
I have a really strange problem. On one of the computers
in my house, parts of the internet keep on disappearing.
Sometimes half the internet is inaccessible, and sometimes
it's just a couple of sites (google is a favorite for this
problem).<br>
<br>
This is, most definitely, NOT a router or ISP problem.
Other computers on the same network are working fine. A
virtual machine connecting via a bridge on the same
network is working fine (via NAT it does not). <br>
<br>
Bringing the interface down and back up does not help.<br>
<br>
Existing connections remain connected, without a problem.<br>
<br>
The only thing that restores connectivity is rebooting
(!!)<br>
<br>
There is nothing out of the ordinary in the routing table.<br>
<br>
Ideas?<span class="HOEnZb"><font color="#888888"><br>

Does ping work when the internet is 'down'? If so, I would
go for:<br>
<br>
TCP Timestamps, TCP SYN Cookies, Selective ACKs, Window
Scaling<br>
<br>
try eliminating all of them ;) <br>
