Have you checked /etc/nsswitch.conf? Make sure you have a line that looks like this:

hosts: files

If you do, then verify /etc/hosts and make sure you have no typos. If you can ping by IP address, you should be able to ping by hostname.

hi frnd
i tried with the option of nsswitch.conf and it worked
thank you so much

bye
thanx again
