raspberry pi2 - Internet not connecting through hostname, but connecting through IP

Former Member
Former Member over 10 years ago

Hi

Thanks in Advance

Am using Rapsberry Pi2 with Raspbian Debian Wheezy OS, configured the network as static with my LAN Connection and accessing pi2 by Putty. I tried to ping google.com, am getting the following response 

pi@raspberrypi ~ $ ping google.com

ping: unknown host google.com


but if ping with IP Address, it is working. I tried with browser in pi2, google.com is not working whereas IP is working in browser.

 

pi@raspberrypi ~ $ ifconfig

eth0      Link encap:Ethernet  HWaddr b8:27:eb:81:d6:48

          inet addr:192.168.1.141  Bcast:192.168.1.255  Mask:255.255.255.0

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          RX packets:1542 errors:0 dropped:0 overruns:0 frame:0

          TX packets:529 errors:0 dropped:0 overruns:0 carrier:0

          collisions:0 txqueuelen:1000

          RX bytes:127751 (124.7 KiB)  TX bytes:103054 (100.6 KiB)

lo        Link encap:Local Loopback

          inet addr:127.0.0.1  Mask:255.0.0.0

          UP LOOPBACK RUNNING  MTU:65536  Metric:1

          RX packets:316 errors:0 dropped:0 overruns:0 frame:0

          TX packets:316 errors:0 dropped:0 overruns:0 carrier:0

          collisions:0 txqueuelen:0

          RX bytes:25456 (24.8 KiB)  TX bytes:25456 (24.8 KiB)

 

I don't know why the internet connection is not working, when am using hostname, Because of this, i couldn't get apt-get update, apt-get install, wget- ....

    Can you show the network configuration file ? Did you specify one or more DNS servers ?

    Simply your DNS is not resolving. So edit or create /etc/resolv.conf adding: (Google public DNS)

    nameserver 8.8.8.8    

    nameserver 8.8.4.4

    Edit: element14Dave could you please move this to Raspberry Pi section. Gracias!

    Clem,

     

    it is correct but - without the network configuration files - if Gunasekaran has already a different DNS defined in the network specifications or somewhere else maybe that the google DNS will be overidden and the name resolving generates anyway issues.

    netmask 255.255.255.0

    gateway 192.168.1.1

    preferred dns 202.138.103.100

    alternate dns 202.138.96.2

    That means you are running a resolvconf. Try adding to network config file above after gateway line:

    dns-nameservers 8.8.8.8 8.8.4.4
