Networking in LFS

MTK358 · 06-19-2011, 01:15 PM

I finally got my LFS system to boot again (), but I can't really continue without an internet connection to get more packages.

The LFS system is in a VirtualBox VM.

So how do I commect it to the internet? I know hardly anything about networks other than that you can enter a URL or address and you can magically transfer data to and from the address.

Hi,

Is dhcp used by VirtualBox VM to give network access? If so: Have a look here: BLFS - DHCP and DHCP Client Configuration

LFS already covered the setup for the static configuration (chapters 7.11, 7.12, 7.13).

If dhcp is needed and you did do chapter 7.13.2, do remember to remove the ipv4 file. Make sure that directory holds just the one(!) config file, be it ipv4 for static or dhclient for dhcp.

Hope this helps.

What do you mean by "used by VirtualBox"?

In case this is a misunderstanding about VMs, remember that a VM works just like a physical PC to the smallest detail.

As far as I know it the VirtualBox emulates a wired connection.

If you setup your virtual machine to use the NAT-option for the network Virtualbox will run a DHCP-server for the network the VM is in. But off course you can setup your OS with static network settings.

What is "NAT", and what do you mean by "the network the VM is in"?

NAT is the abbreviation of Network Address Translation. If your VMs network controller is set to NAT Virtualbox acts the same way as a router. It runs a DHCP server and puts your VM into its own network. If you set it to Bridged the VM will act as it would be in the same network the host is in.

I started this thread to figure out some things that I don't understand: http://www.linuxquestions.org/questi...orking-887346/

Anyway the LFS system is not intented to be a server or router. All I want is to be able to download files from the Internet.

As far as I know, I have a dynamic IP address.

Quoting the now relevant parts from post #2:

About the dhclient file: You probably do not need the <add additional start parameters here> parts, just leave the -q and -q -r setting as is.

Hope this helps.

I didn't get anywhere even close to that part of the LFS book. How do they expect me to do all the preceeding steps without networking?!?!?!?!?

I guess I have to download them on the host machine, make a CD image from them, and mount that on the VM.

Stuck at the beginning of chapter 4 (unable to download packages because of no networking).

spiky0011 · 06-21-2011, 02:38 PM

Can you download them on to a pen drive then transfer them to lfs, I know it,s long way round, but if you get all the packages on to pendrive you could just get them as you want. I done lfs 6.7 they supply a tar ball of all packages, I just exploded it into source dir. 6.8 dosn't do a complete tar of all packages so a pendrive is next best

Hi,

Until you have a working network you need to be a bit creative:

Just a thought:
- download, using host that runs VM, the needed packages and put on an usb stick,
- mount usb stick from LFS (VM client).

Hope this helps.

Will this help http://www.hotfilesearch.com/downloa...s-6.8.tar.html

Why use a USB stick? What I would do is make an ISO image and put it in the virtual CD drive.

How will the LFS packages help me do BLFS?
