Connect Bt4 to the internet

« on: May 26, 2011, 12:08:47 PM »

Hey guys!

I kinda have a little issue with connecting Bt4 to the internet.
Im behind a Firewall and running Bt in Vmware.
but im not able to get it to connect to the outside and ble to connect in the LAN and see all the connections There but not able to get to the internet.

What configuration do i need?
What do i need to do in order to get it to work?

Thanks!!

Are you able to ping IP addresses assigned to other physical machines, or only IPs within your one machine (ie main OS and other VM's)? If the latter, you might need to reconfigure the BT VM to a different network connection type. I haven't used VMWare much, but in VirtualBox you are able to configure the network connection type to bridged, NAT, internal, etc. Bridged/NAT will allow you to access outside of your host OS, otherwise you're only able to ping IP's within your host OS.

Sounds like you have it set to host-only, unless those other LOCAL network machines are not VM's as well. As lorddicranius said, you'd need to go NAT or Bridged, to fix that.

Sounds that way, anyway... The other possibility, if you statically assigned an address, is that your gateway is set wrong, on the BT guest... You could hit local subnet machines, but nothing more, if you aren't talking to or configured for a gateway machine / router, somewhere.

Thanks for the response!!

When i put it in NAT im able to ping all the computers in the LAN, but when i put it in bridge i get.

Code:

root@bt:~# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

root@bt:~#

Meaning its not getting an Ip from the DHCP server.

Have you run the command "/etc/init.d/networking start" yet? If so, try running the command "dhclient" to see if you can pull down an IP address.

I almost suggested dhclient, but since you'd said you were able to connect to other local machines, I assumed you were already getting an IP and connecting...

Glad it's working for ya. That's something to also keep in mind when switching between BT4 and BT5: BT4 doesn't start the networking daemon upon bootup (by default), while BT5 does start it.
