Just a quick note: I use VirtualBox daily at work. It provides excellent emulation for my original XP install (the one that came pre-installed on my Dell box!) while my main OS is Ubuntu. Setting up networking is not as straightforward as with VMWare, so here is what I had to do:
First, edit /etc/udev/rules.d/20-names.rules and make sure this line exists:
Then create this script - you will run it whenever you wish to reconfigure your network:
#!/bin/bash echo "Erasing old configuration" sudo route del default sudo ifconfig tap0 down sudo ifconfig eth0 down sudo ifconfig br0 down sudo brctl delbr br0 sleep 1 echo "Creating virtual interface" sudo chown chris /dev/sdc1 sudo tunctl -t tap0 -u chris sleep 1 echo "Creating bridge interface" sudo brctl addbr br0 sleep 1 echo "Making physical interface promiscuous" sudo ifconfig eth0 0.0.0.0 promisc sleep 1 echo "Binding bridge to physical interface" sudo brctl addif br0 eth0 sleep 1 #sudo ifconfig br0 10.255.203.34 netmask 255.255.255.0 echo "Configuring IP address" sudo ifconfig br0 18.104.22.168 netmask 255.255.255.0 # sudo dhclient br0 # The new way! sleep 1 echo "Binding bridge to virtual interface" sudo brctl addif br0 tap0 sleep 1 echo "Enabling virtual interface" sudo ifconfig tap0 up sleep 1 #sudo route add default gw 10.255.203.254 echo "Adding default route" sudo route add default gw 22.214.171.124 echo "All done!"
What’s that, then?
We start by getting rid of any existing configuration; then I change my virtual interface device’s owner to my own user, since I am logged in as a non-root user. Obviously you need to replace ‘chris’ with your own user name. From now on, tap0 will be the virtual interface seen by VirtualBox.
I make sure that my real interface is in promiscuous mode, which then allows me to bind it with a bridge interface.
All that is left to do it configure my bridge interface so that it can take over communicating with the rest of the world!
