Recently i installed Centos 6.4 on my Virtualbox and the network card doesn’t start automatically at first boot. My network card IP details doesn’t show up. Have you got the same problem just like mine? If yes, don’t worry. You’re on the right track. Here is the quick steps about how do i enable it on every reboot?
#ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
As you see in the above output, my server network card doesn’t found.
To resolve this:
Edit /etc/sysconfig/network-scripts/ifcfg-eth0 file,
and change ONBOOT=no to ONBOOT=yes.
For Dynamic IP:
DEVICE=eth0 HWADDR=08:00:27:3F:95:CF TYPE=Ethernet UUID=84331ed6-f36d-44a0-978e-b3ca381b234f ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=dhcp
For Static IP:
DEVICE=eth0 BOOTPROTO=static ONBOOT=yes NM_CONTROLLED=no HWADDR=08:00:27:3F:95:CF IPADDR=10.1.1.219 NETMASK=255.255.255.0 GATEWAY=10.1.1.1
Edit the /etc/resolve.conf file and add the DNS details.
##google nameservers nameserver 8.8.8.8 nameserver 8.8.4.4
That’s it.Reboot and enjoy!
