[SOLVED] Virtual Machine cannot access the internet

\/4A · 09-19-2012, 08:00 AM

Hello,

I've setup a virtual machine on VirtualBox. The virtual machine is an Ubuntu Server 12.04

While I can access this virtual machine from the LAN, the virtual machine cannot seem to access the internet. Even if I try

Code:

:~$ ping google.com
ping: unknown host google.com

Same thing with any IP number.

From any PC on the LAN I can ping into the virtual machine and I can even SSH into the virtual machine.

Would really appreciate some help on this, pls.

Hi, \/4A
Are you using a NAT or bridged connection? If it's NAT then the external interface (it needs to be told to forward the traffic to and from the internal interface (VM interface in our case).
If you use bridged connection it should just work unless your router is told to block the packets.

Virtualbox is setup to use a bridged connection and I very much doubt the router is told to block any packets (how would I know?)When you say router, do you refer to the physical router that my PC is connected to, or some virtual type of router in VirtualBox?

ping: unknown host google.com

Then you usually go to the next command either dig or nslookup to test that your name resolves.

I assume you need your isp's or opendns ip dns number in the mix.

I doubt this but in rare cases you may need to add in the www to some addresses but this should resolve to google.com

I think I know where the problem started.
The Ubuntu Server 12.04 installation on VirtualBox was initially set to DHCP, so I modified the /etc/network/interfaces file. Looks like I hadn't put references to gateway and broadcast.

I've done so and all seems OK now.

Thanks everyone for your help.
