I have OpenDNS set up on my router, however I'm getting a strange situation. The OpenDNS Welcome page confirms that OpenDNS is working on my Windows XP laptop and on an Ubuntu netbook but not on my Ubuntu desktop (it gets the "oops" page)!
Does it have something to do with the fact that the desktop is wired to the router while the laptops are using wireless? Or is it possible that the Ubuntu desktop is somehow configured to use a certain DNS server (not OpenDNS) instead of getting it from the router... how could I check that? I rebooted the ubuntu desktop and it's still getting the "oops" page.
