Host: Ubuntu10.04 Emu:BT4 R1 on VirtualBox - Networking

[brodeur235]

My host machine is a lenovo thinkpad running ubuntu 10.04 karmic koala and I am attempting to emulate BT4 R1 in virtual box, but I have literally been trying to figure out how to start networking for over 6 hours.. Literally. I'm very frustrated to say the least. Here's the steps/output/settings for some of the things that I've tried for this particular setup. First off, the output of my host machine after running this command to detect my NIC (I think), reads:

[command]

sudo lshw -C net

[output]

This seemed kind of interesting to me, even though I'm not entirely sure what this output is/means, the "*-network DISABLED" indication right above an entry with the line "logical name: vboxnet" makes me think and wonder..

Virtualbox configurations network-wise looks like this:


Once I boot up and log in as root in BT4 R1, I try to configure networking to work one of several ways.

One way is by running:

/etc/init.d/networking start

But this only results in the browser thinking it can load pages, and taking a while to figure out that it actually can't. Or, I will try to ping google via the cli and it will take a while and not work.

I've also tried to manually set up the eth0 interface with the dchp server by using the following two commands:

ifconfig eth0 up
dhclient eth0

But this just results in the command line trying to ask the DHCP for what it needs and never getting a response, until the command gives up, reporting that it will "sleep" or something similar.

I've also tried to manually assign an IP instead of asking the DHCP server for one. I don't actually want or need to do this, it was just a means to an end to try and get networking up, but its still not working anyways. Here are the commands:

ifconfig eth0 100.100.100.1 netmask 255.255.255.0 up
route add default gw 100.100.100.2 eth0

I also added a dns server IP to the resolv.conf file in combination with these two commands, and still no luck at at with any tests with wget, ping, or browser tests.
[/code]

Any/all help is very mch appreciated, and I'm sorry for wasting space on the forum for such a trivial question, but honest to god I'm fed up trying to do it myself, I really need some help.

P.S.
This thread on the virtualbox forums was kind of helpful, though it just let me know a bunch of people in similar situations were experiencing similar problems, and never presented any solution..

OK, you have clearly put some effort into trying to resolve this.

Resolving this is really going to all be about properly diagnosing the cause of the problem, so I'll throw some of ideas of things to check at you.

With your virtual adaptor setup in bridged mode your BT virtual machine will attempt to obtain an IP address off a DHCP server on the network that eth0 from your Ubuntu host system is attached to. Is that DHCP server functioning correctly? There is no filtering or other limitations on the use of MAC addresses on your switch is there - since this will involve traffic from two different MAC addresses coming from the same physical host, and MAC filtering on your switch/router would prevent this from working.

What output do you get from the commands 'ifconfig', 'cat /etc/resolv.conf' and 'route' after running '/etc/init.d/networking start'? Do you see evidence of an address being assigned to an interface after running that command? Can you do a DNS query? Can you ping your local default gateway, or the eth0 interface of your Ubuntu host? (Be aware if you have a firewall on your Ubuntu system)

What about performing the same troubleshooting steps after manually assigning details.

Also try capturing packets using Wireshark on your Ubuntu system and on your BT system. What do you see when you try and ping or do lookups from your BT system? What should you see? (Compare with what happens on your Ubuntu box)

What about if you set the network to NAT mode in VirtualBox?

[Archangel-Amael]

This maybe a long shot but in your vbox setting above where it says "advanced " There is a check box for cable connected, check it and then start the guest and see if it works. (see also your picture above). That is really the only thing that I can see that stands out as being different to what I can produce here.
As for the lshu output I get the same thing both with and w/o a cable attached to the host.

dork@dork:~$

Also are you trying to bridge to your host's eth0 - or another adapter?
The reason I ask is because you mention "after running this command to detect my NIC (I think), "
lshw is really not the right command to configure a network card, it merely shows you some information.
A better choice would be ifconfig considering it is used to configure cards, that are kernel resident.
Just because your system recognizes the card doesn't always mean it is communicating with it.

Silly me!! I had firewall configured. Once I turned it off everything works fine. I don't know anything about iptables so your on your own but thats how to set it up. For now you have to call the following before starting the virtual box. Don't know how safe this is.

sudo iptables -vI INPUT 1 -i vboxnet0 -j ACCEPT
sudo iptables -vI OUTPUT 1 -i vboxnet0 -j ACCEPT

Create a custom launcher

tee ~/Desktop/virtual-xp.desktop > /dev/null <<_EOF_
[Desktop Entry]
Type=Application
Name=XP
Comment=Dark Edition V8
Exec=bash -c "gksudo 'iptables -vI INPUT 1 -i vboxnet0 -j ACCEPT'; gksudo 'iptables -vI OUTPUT 1 -o vboxnet0 -j ACCEPT'; sleep 1; vboxmanage startvm 'Virtual-XP'"
Icon=/usr/share/icons/application-default-icon.png
StartupNotify=true

NoDisplay=false
_EOF_
chmod 755 ~/Desktop/virtual-xp.desktop

Hello all,

I am also having issues with my internet connection in BT4 via virtualboxhttp

going on 4 hours now.

I am extremely tired and frustrated. So for time sake, I am going to post an image of the output I get at the terminal when I try the code that brodeur235 tried. I am still a noob @ linux but I know my way around terminal somewhat. It seems like maybe I missing a file. I just dont know. Any help would be great. Like I said I am just ready for sleepy, sorry for the sloppy post. If you need info and specs I will reply as soon as I can. Thanks
