Dear Folks, After replacing the second network card with a new one, NetworkManager refuses to listen to the startup scripts (shown below). It always calls the new interface eth2, not eth1. 1. Where does NetworkManager hold its definitions of network interfaces? 2. Does the UUID have something to do with my problem? How does this get generated? Should I uses uuidgen to make a new one for eth1? I would really like to understand NetworkManager, but it makes things more complicated for me on this machine. $ ls /etc/sysconfig/network-scripts/ifcfg-* /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1 /etc/sysconfig/network-scripts/ifcfg-lo $ cat /etc/sysconfig/network-scripts/ifcfg-eth0 # Networking Interface DEVICE=eth0 BOOTPROTO=none HWADDR=00:24:1D:1F:7E:77 ONBOOT=yes TYPE=Ethernet NM_CONTROLLED=yes USERCTL=no IPV6INIT=no IPADDR=192.168.0.1 NETMASK=255.255.255.0 PREFIX=24 NAME="System eth0" UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03 $ cat /etc/sysconfig/network-scripts/ifcfg-eth1 # Please read /usr/share/doc/initscripts-*/sysconfig.txt # for the documentation of these parameters.
