HINTS! Internet connectivity w/ Ubuntu 7.04 Guest & NAT

[garmischgirl]

Thank you GonzoVBX-1 for your assistance - these instructions helped alot! It took alot of searching to find a simple solution to connecting to the Internet using VirtualBox (VB). This is my step-by-step for Ubuntu 8.10 installed as a guest in VB on an XP host (Sony VAIO laptop). The goal here is to create a static IP on the Ubuntu installation using settings assigned by DHCP from VB (IP address, NetMask, Gateway) and the DNS server settings from the host.

Step 1: Determine host computer DNS server: on host machine (XP) > click on Start > Run > type command > Enter > type ipconfig /all > Enter > about halfway down in the Connection section, write down what is noted for DNS Servers - example: 192.168.1.254

Step 2: Set VB adapter to NAT: open VB > click on Settings > Network > Adapter 1 tab > checked Enable Network Adapter > Adapter Type > PCnet-FAST III (Am79C973) > Attached to NAT > MAC Address - leave as is > check Cable Connected > click OK.

Step 3: Confirm Ubuntu network connection is set for DHCP: start Unbuntu guest in VB > on the top right of the toolbar, right click on the first icon that looks like two monitors > Edit Connections > highlight Auto eth0 > Edit > click on IPv4 Settings tab. The boxes at the top for Connect automatically and System setting should both be highlighted/filled > confirm or change the Method is set to DHCP. If it's already set to DHCP, proceed to the next step. If you had to change it to DHCP, click OK, and Restart Ubuntu.

Step 4: Determine Ubuntu network settings: System > Administration > Network Tools > under the Devices tab, the default Network device shows Loopback Interface (lo) > click on the drop-down menu to the right, and change the device to Ethernet Interface (eth0). Under IP Information, write down the IP Address and Netmask. Next, click on the NetStat tab, and the default Display is Routing Table Information > click on the Netstat button to generate the settings. In the Gateway column, write down the one address that is not just zeros - example 10.0.2.2. Close out of the Network Tools.

Step 5: Set static IP on Ubuntu: return to Ubuntu network connection settings > on the top right of the toolbar, right click on the first icon that looks like two monitors > Edit Connections > highlight Auto eth0 > Edit > click on IPv4 Settings tab. The boxes at the top for Connect automatically and System setting should both be highlighted/filled > change the Method to Manual > click the +Add button > enter the IP Address, Netmask, and Gateway settings that you retrieved in Step 4. In the DNS Servers field, type in the setting you retrieved from the host computer in Step 1 > leave the Search Domains blank > click OK.

Hopefully, you are now connected - you should see the time as corrected to your time zone. This connection works whether your host computer is wired or wireless, and you should connect at this point automatically. Try to open the Firefox browser. Also, go to System > Administration > Update Manager to get all of the software updates and patches - there will be 200+ after the initial installation.

Mac os x 10.5.7 running VB 3.02

Installed Ubuntu 8.04 and it worked flawlessly
Installed Debian 5.02 also, but cannot for the life of me get internet to work.

ping is working, but Internet is not.

I replicated the Max os x /etc/resolv.conf and /etc/network/interfaces onto the Debian OS and

/etc/init.d/networking restart

but still no luck. I also tried to add the static configuration into interfaces but no go either.

installed the virtualboximages.com/Debian-5.0-rc2 image. everything works well including ping but internet via browser, wget apt-get is blank or slow. I imagine it's a resolv.conf issue but I am replicating what is in the host and the other ubuntu image guest and its still not working.

What is the difference between an ethernet cable and an ethernet "crossover" cable? I would like to wire my two computers together so that data could be transferred. Both computers have an available ethernet port. I have additional ethernet cables available. How do these cables differ from the crossover variety? How much should I expect to spend on a crossover cable?

How do you make Yahoo chatrooms work through a firewall? The "help" says you can use some code to allow the chat to operate without disabling the firewall. They give the code, but no instructions and I'm hopeless with this stuff.
