If your /etc/sysconfig/network-scripts/ifcfg-eth? files don't have the
right HWADDR to match your NIC cards (for example if you cloned a disk
from a different machine or swapped cards after setup), the system can
detect them in the wrong order and even use interfaces you had not set
up. The 'mii-tool' command will show which interfaces have link active
. If you can't ping your router, try checking one cable at at time to
make sure you have link on the right interface name and that ifconfig
shows that it has the expected IP address.
