Eth0 not present in Natty (vmware)

[jaywhy13]

Hi all, hope you all can help. I just installed Natty inside of VMware and eth0 for one was missing from my /etc/network/interfaces file and for two it doesn't work no matter what I've tried.

From vmware side I've tried setting the network connection type to Bridged and NAT. I've tried several /etc/init.d/networking restart commands. I've also tried both static and dhcp options in the interfaces file.

Dhclient returns instantly. I can ping and use nslookup but I can't load websites.

HELP?!?! :( :(

Could you post the result of the command ifconfig?. Select NAT in vmware.

Your interface eth0 looks good. Your computer got its IP address and the traffic has no error. The contents of the files /etc/network/interfaces and /etc/resolv.conv seem good too.

If you are not able to load websites, it could be due to a DNS problem.

Type these additional commands and post the results:



route -n
ping -c3 8.8.4.4
ping -c3 google.com
wget www.google.com

Figure it will continue to fail

The two ping commands worked fine. The interface eth0 and the DNS client of you Ubuntu virtual machine look good. I believe that the problem is external to Ubuntu.

What OS are you using in your host (XP, Vista, Windows 7)?. Are you using a firewall there?. Maybe the firewall is cutting the http traffic because you have not given permissions to VMware. Try to disable the firewall and check if the command wget is completed.

I'm running windows 7, I tried disabling my firewall. Nothing :( Wget still times out.

Do you have a router with a http interface in your LAN?. If so, change the interface to Bridged and check if you are able to connect to the router (or to any other web server in your LAN) using Firefox from Ubuntu.

I have used VirtualBox but I have no experience with VMware. According to the previous commands I think that the problem has its origin in the host or in the router. I believe that Ubuntu is not guilty.

[jaywhy13]

How would I go about "connecting" to the router though. I have two different setups. I work from home / work. Both places I have a wireless router, running Windows 7 Premium btw.

When I set the network to bridged I never get an IP.

Both networks (home and work) have computers running Windows 7 Premium playing the role of wireless router. If so, they do not provide any web interface for the routing configuration. Therefore, forget my proposal.

I suppose that your host is a different computer from those routers.




When I set the network to bridged I never get an IP.

According to your previous comments, you are using wireless. So, try to select a wireless bridged adapter in the VMware network setup. You have probably selected a wired adapter. In this case you are connecting your virtual machine using the wired adapter and this is reason because you do not get any IP.

Two questions:

1) Are you able to load web sites normally from your host machine?.

2) Have you some web, ftp or file server in your LAN?. I would like to test the TCP connections between your Ubuntu virtual machine and other computer of your LAN.
