strange eth problem with linux
I have install RHEL AS 4 update 3 on a machine. When plug in a cable to the intel 1G eth port (the otherside is connected to a router), everything works fine. But when I unplug the cable, run ifconfig -a shows no eth0 and corresponding MAC address. So the machine only shows eth (MAC address) when there is a working eth connection. Is that normal? I need to use the MAC address when there is no eth connection.
service network restart : e1000 device eth0 does not seems to present delaying initialization.
lsmod shows e1000 module is there but no one is using.
