I have a Fedora machine which isn't normally on the network, but has been on the network before. I tried for several hours to connect to my cable modem and turn on networking, but failed. I know the modem and cable is okay because it works with a different machine. For the fedora machine, the error message is:
# /etc/sysconfig/network-scripts/ifup eth0
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: Active connection state: activating
Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/4
** (process:5049): WARNING **: _nm_object_get_property: Error getting 'State'
for /org/freedesktop/NetworkManager/ActiveConnection/4: (19) Method "Get" with
signature "ss" on interface "org.freedesktop.DBus.Properties" doesn't exist
Error: Connection activation failed.
Does anyone know what I should do to get networking working? What are the steps to diagnose and correct this?
Any help is very much appreciated.
