I booted Knoppix, and again I had the same problems. Firefox opens a "checking compatibility of add ons" window for several minutes, then this disappears, then several minutes later the FF browser pops up. From here I disabled IPv6 again, closed and re opened FF. I tried to access the knoppix website first and that didn't work, so I typed in 72.232.180.133 again, and it worked! Brought me right to the Knoppix site, and I made note of the google adds that showed up on the side. After that I could access any site freely, so here I am. So I guess the same procedure did yield the same result which is rather interesting. But since it takes ten minutes from when knoppix loads to when I can access the net, I am trying my luck with a persistent disk image saved to a USB drive.

The plot thickens...
I booted knoppix this morning, with the command home=scan and I chose the second option down (I forget the exact details) and I loaded my persistent disk image from my USB device. I opened iceweasel (FF) and I my information from last time had been saved (history et cetera), but when I tried Knoppix.net, I got nothing. So again I went to 72.232.180.133 and it worked, and after that everything worked fine. Thats where I am this morning, I still don't fully understand what is going on here.

Revive DNS
For consistently good results with dns, I've found it best to place your isp's primary and backup nameservers inside the routers setup page. This helps bypass issues with the little dns-forwarding code inside most soho routers that do not always follow the internet specs and are may be tuned to how other os's/manufacturer's define the protocol. Linux sticks to the exact internet protocol, and sometimes dns can get hung, or be very slow when it deals with these internal router dns-forwarders. You can help bypass it by specifying the real primary and backup dns servers in the router setup page. If you do this, restart networking, or just reboot the computer.
Of course you can use alternate dns servers, like those at the bottom right of the page at opendns.com, but there are others. For security reasons, don't make them up, nor blindly use any that you see in other postings - verify them by visiting the site or use some other form of verification.
For the temporary nature of Knoppix, or if you don't have access to the router, you can temporarily edit your /etc/resolv.conf file, and place your real dns server addresses at the top of the list - leave the one you may have already found (likely to be that of the dns-forwarder, at the bottom.)
I'll use some fake dns addresses here as an example - use the real thing obviously!
Quickly edit:
Code:
sudo nano /etc/resolv.conf
Edit somewhat like so:
Code:
nameserver 123.45.678.901
nameserver 123.45.678.902
nameserver 192.168.0.2
These are fake/example addresses of course, but this will take affect immediately and will persist until reboot, OR until your system gets a re-lease of it's dhcp address. When a re-lease occurs, you might find that /etc/resolv.conf gets overwritten without the new nameservers, but for the typical knoppix session, this should hold for awhile for those who don't have access to their router setup.
