Check network connection is Ok


Hi All,

I was trying to install 11g on Oracle Linux 6.2, as per the document (the document just says execute the below command to check whether network is ok without a result to compare) I executed the following command and got the below result. Please advise whether is there any issue below lines, if any kindly advise how can i fix them. Thanks in advance,

# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
NM_CONTROLLED="yes"
ONBOOT=yes
HWADDR=00:11:43:72:54:8B
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03

That's just the setup for your eth0 NIC. Whether its correct or not is specific to your system.
Have you only got that eth card?
Can you reach any systems on your LAN?
Can you reach google?

Try
Code:
ifconfig
as root or
Code:
/sbin/ifconfig
as non-root and post the result(s)


You'll find this handy http://www.linuxtopia.org/online_boo..._6_deployment/

If you "can reach google or any website from linux PC" then the network connection is OK.
