How about a pattern in the routing, or the HTTP request, or the HTTP reply, or the TCP packets returned? Don't look for patterns like that, you'll probably drive yourself nuts. > What seems so strange is that I can successfully ping ANY website on the > internet from my machine.

That's a possible point of trouble. Download ethereal or use tcpdump and see what difference there is between the sites that work and those that don't. Try using telnet to connect to the problem sites (use "telnet site.name http") and see if anything looks funky. If you don't understand the output of ethereal or telnet, post the relevent details to the list so folks have enough information to diagnose your problem a little better. > Anyway, I am willing to send anyone my kernel config file, ppp.conf, or > any other file that might be helpful in solving this problem.
