Hey all, while checking some setups from my Linux CentOS 6, it came to my mind how boring is to remember simple steps to start my eth0 so I can access my machine remotely.
To do that simply start the service as root first
Once you have your network working edit the ifcfg-eth0 file located on /etc/sysconfig/network-scripts (note that this path may change in different Linux distributions)
Change the ONBOOT=înoî to ONBOOT=îyesî
restart the system and itís done.
Obs. It should work with any eth*.
