I am not able to ping google.com.
 

Hi

I am not able to ping google.com.
I made the changes in ifcfg-eth0 IP address to static.it was dchp.

please help.

What linux distro and version are you running?
??? Did you mean dhcp?
Do you have an internet connection?
What is the complete path of the configuration file you changed?
jdk

Yes . i hv internet connection. i changed IP from /etc/sysconfig/network-scripts/ifcfg-eth0

Now i have done the BOOTPROTO=dhcp and now I am able to connect to google.but whenever m doing IP adress to static its stop working .
no idea why it is.

When you configure with a static IP address, you'll also need to configure a domain name server manaually. Check /etc/resolv.conf for a nameserver entry, and add as necessary.

Ok .Thanks for information :)

If your static IP isn't on the same subnet as the IP you've been getting from DHCP then you may also have to change hostmasks and default gateways / routes accordingly.

If you're on a network which provides DHCP why are you trying to configure a static IP? Be aware that you also should select a static IP on the correct subnet, but also beyond the scope of the pool of dynamic addresses which can be assigned by the router.
