You have defined IPv6 DNS higher up.


Then try to ping, by number, "173.194.45.160", or some numbers up
(google.com).

I have no problem reaching the Internet, it's just DNS on that one
computer that's failing.

Ok.


Then try "host -v google.com".


# host -v google.com

You get an IPv6 address as answer. And some IPv4 addresses before.



But then

# ping google.com
ping: unknown host google.com

So, host works, but apps that require DNS look up don't.

"ping" wants an IPv4 address. Try ifping6 would work. And plain "ping"
too, but you need to add some extra options. A quick look at the manual
says "-I".

Perhaps "ping -v ..." would tell you something more.


Ah, I forgot - post this:

cat /etc/hosts.conf | egrep -v "^[[:space:]]*$|^#"
