ubuntu 9.04 : DNS problem

Thu Jan 30 14:57:28 UTC 2014

Hello,

We have 2 network cards/cables eth0 and eth1. We make a bonding in order 
to have 2 gbits/second. We called this new connexion "bond0".
We are able to ping our switch and our router. But we can't ping the 
DNS  of our Internet Service Provider. We have also an error message 
when we attempt to rester network services. And we can't open an 
internet webpage.

Please find below usefull configuration files ans commands :

------------------------------------------------------------------------------------------

/*commande /etc# sudo /etc/init.d/networking restart

*/

root at jupiter2:/etc# sudo /etc/init.d/networking restart
  * Reconfiguring network interfaces...
   Ignoring unknown interface eth0=eth0.
Ignoring unknown interface eth1=eth1.
SIOCADDRT: File exists
Failed to bring up bond0.
