Does anyone know how to STOP Oracle Linux 6.4 from restarting itself after a successful shutdown ?
Assuming your network interface is eth0, execute "$ ethtool eth0", like below, and indicate what you get for the lines "Supports Wake-on" and "Wake-on.
lx04:/root $ ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
Supported pause frame use: No
Supports auto-negotiation: Yes
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: Yes
Port: Twisted Pair
Supports Wake-on: pg
Current message level: 0x0000003f (63)
drv probe link timer ifdown ifup
Link detected: yes
Then check in your BIOS (usually under APM) for any enabled power-on settings associated with PCI or PCIe bus (your NIC will use one or the other).
