Symptoms include: (Remember, command-line environment.)
1) Unable to enable network card (e.g. eth0).
2) Network card won't enable on startup/boot.
3) Command 'ifconfig' does not show any network interfaces other than Local Loopback.
The only resolution I have found to get you system online without a GUI interface is the following
1) Remove/Uninstall NetworkManager
Easiest way to do this is these commands as root:
- rpm -e NetworkManager
- yum remove NetworkManager
- apt-get remove NetworkManager (This may work for Ubuntu)
As root, type the following:
system-config-networkFollow the prompts and this should have your network cards configured in no time.
3) Lastly, you have got to check to see if the network services will run on boot. Check this by running the following (as root):
chkconfig --list|grep networkIf the results are 'No', then run the following:
chkconfig network onAfter this, the service should then start on boot automatically.
Once all this is done, reboot your machine and your network should be working fine.
