I just started using raspberry pi.I am trying to sharing wifi internet connection with Raspberry Pi 2 - MODB through LAN (Headless mode)
What I have done so far?
Flashed SD card with 2015-05-05-raspbian-wheezy image
Enable “Allow other network users to connect through this computer‘s Internet connection” option for Wireless Network Connection Properties.
Append ip=Fixed IP:: Lan IP in cmdline.txt file
Open SSH with Fixed IP on PUTTY.
Issue:
Now through SSH, I am able to ping 8.8.8.8 IP which means I got internet access to my raspberry module. But not able to ping DNS - http://google.com, getting error unknown host. And also not able to perform and updates, getting error Failed to fetch http://___
Getting confused whether raspberry board got internet access or not. And if yes, then why not able to access DNS and updates.
Outputs:

cat /etc/resolv.confnameserver 8.8.8.8line should be sufficient. This file configures the DNS server(s) for the system hence failing to resolve domain names when was not configured.
