Loss of Networking on Linode after Update or Reboot

We have recently seen reports of users who experience issues with networking on Linode after installing updates or rebooting your server.

Description 

Linode has auto-configuration features enabled by default on their servers and it must be disabled. Failing to do so can result in a loss of networking after a reboot. Users commonly notice this issue after installing updates that require a reboot.

Workaround

First, you need to disable the feature in the Linode interface:

• From your Linode's Summary Page go to the Configuration Tab
• Click Edit to the right of your current configuration
• From this new menu, scroll down to the bottom and turn off Auto-configure networking
• Click Submit

After this has been completed, ensure your networking configurations are correct:

# nano /etc/sysconfig/network-scripts/ifcfg-eth0

NETWORKING=yes
GATEWAY=$PUBLIC-IP

Ensure you replace $PUBLIC-IP with your public IP.
