Maybe you should ask them exactly what they changed. Are you quite sure that whatever change they made is what caused this problem, and it isn't just a coincidence? Looking at the messages, it looks like there is something really wrong with your network settings. Do you get the same series of errors if you just type "ifup eth0"? If so, then you could post the output of "sh -x /sbin/ifup eth0". -- Dave |
