Using the default live cd install of Fedora 14, I find that my headless server is using NetworkManager for ip config. Fine. I run system-config-network-tui and choose Devices, only to find none listed. What next?
What do 'ip a' and 'cat /etc/sysconfig/network-scripts/ifcfg-eth0' show ?
/etc/sysconfig/network-scripts/ifcfg-eth0 doesn't exist. I've manually created that file now, and disabled NetworkManager so I cannot answer your other question. However, eth0 was in use, and being managed by NetworkManager. ifconfig showed the device.
This problem still exists. # ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000 link/ether 00:01:02:03:04:05 brd ff:ff:ff:ff:ff:ff inet 192.168.1.11/24 brd 192.168.1.255 scope global eth0 inet6 fe80::fe80:fe80:fe80:fe80/64 scope link valid_lft forever preferred_lft forever # cat /etc/sysconfig/network-scripts/ifcfg-eth0 cat: /etc/sysconfig/network-scripts/ifcfg-eth0: No such file or directory
