The uknown host message means that  your box querried for www.rediff.com 
   as per your example and couldn't get an answer . Possible causes include

1. You mistyped the address

    In your example you didn't
2. You are using a firewall which blocks DNS responses and since the
    DNS responses are blocked you get the uknown host message
3. Verify that the /etc/resolv.conf contains the correct IP's of the
     DNS servers of your ISP .
