Hello, my friends.
Help me please.
I have oracle linux server 6.5
Command 'ifconfig -a' shows me good network settings.
Command 'netstat -rn' shows me good gateway.
Network was workable before 'yum update'.
And now in gui I can see: 'No network connection', 'Wired network - disconnected'.
I tried to start my eth0 with 'system-config-network', and result is:
Failed to run:
/sbin/ifip eth0 up
Error: Connection activation failed:
Device not managed by NetworkManager
In file /proc/net/dev after 'eth0:' I can see only zeroes.
How can I resolve my problem?
