    I've got a box running Fedora Core release 3. I'm able to resolve
    names such as www.yahoo.com using nslookup or dig but not using ping.
    "ping www.yahoo.com" returns "ping: unknown host www.yahoo.com".

    /etc/host.conf
         order hosts,bind
    /etc/nsswitch.conf
         hosts: files dns

    I'm logged in as root. What am I missing here?
