LocalNetInstall

This is a work in progress. It is also a mix of Basic Internet Install and Local Net Install that are similar to just installing from the CD, and Hands Off Install that uses a preseed file to automate the whole thing.

sahara is the server. shaz is the blank box that I am trying to install Hoary on.

1. Install Trivial File Transfer Protocol server (The default install uses inetd to run tftpd when a connection is made, so don't try to start it manualy.)

   root@sahara:/ # apt-get install tftpd-hpa

2. Mount the CD (media or image) under the tftpboot dir

   root@sahara:/var/lib/tftpboot # mkdir ubuntu
   root@sahara:/var/lib/tftpboot # mount -o loop /var/lib/tftpboot/ubuntu-5.04-install-i386.iso /var/lib/tftpboot/ubuntu

3. Setup Apache

   root@sahara:~ # apt-get install apache2

4. Make a symlink from apache's doc Root to the CD

   root@sahara:/var/www # ln -s /var/lib/tftpboot/ubuntu/

5. Install dhcp server.

   root@sahara:~ # apt-get install dhcp3-server

6. Set the dhcp server to tell the clients what to boot. I added a default host name, you don't need it but it comes in handy for other things.

   root@sahara:~ # cat /etc/dhcp3/dhcpd.conf
   ping-check = 1;
   filename="pxelinux.0";
   subnet 192.168.1.0  netmask 255.255.255.0 {
           range 192.168.1.10 192.168.1.254;
            }
   
   root@sahara:~ # /etc/init.d/dhcp3-server restart
   Stopping DHCP server: dhcpd3.
   Starting DHCP server: dhcpd3.

   I #'ed out the DNS - routers to make sure the install didn't figure out how to pull files from the net.
7. Boot up the client box, config the bios to net boot and you should get the Ubuntu Hoary screen and Boot: prompt. Yippee!

The above steps should give you an interactive setup.

At this point in time my goal has shifted from a typical install like if you just booted from CD to a Hands Off Install where all the questions have been answered and fed to the installer as preseed. I may get back to the interactive setup, but for now I am focused on using preseed.cfg.

My configs to make a Hands Off Install that does not pull anything from the internet.

Right now a handfull of preseed options need to be passed via kernel options. The kernel only supports 255 chars, so things are cramped. To accomodate this, I dumped some of the paths and made symlinks. That gave me just enough space for now. Note that the path/name of the kernel gets appended, so even trimming that helped.

netcfg/get_hostname= Is blank so that it will pick up the host-name supplied by the DHCP server.

netcfg/choose_interface=eth1 - for laptops, I want it to setup the wifi card, not the wired port. Problem I am having is that some use eth1 and some wlan0. What would be great is if the DHCP server could somehow pass this too.

note: The DHCP server can't pass it, but pretending that the MAC address of your wireless card is 12:CD:56:AB:78:EF you can specify a custom pxelinux.cfg/01-12-cd-56-ab-78-ef (lowercase) instead. It is also possible to use an alphanumeric value that represents the MAC address on a model-specific basis - but I am unaware as to how the conversion works. Basically, say you have three wireless cards where the MAC id translated to caf12d5e, caf12d6b, caf124ea, you could specify pxelinux.cfg/caf12d and pxelinux.cfg/caf12. The first two would match to the first config file and the third would match to the second config file. I'll update on exactly how this works when I figure it out for myself. ~~~

note: this is from my new breezy installer, everything else on this page was from hoary.

Using http://archive.ubuntu.com/ubuntu/dists/hoary/main/installer-i386/current/doc/manual/en/apcs01.html saved to /var/www/preseed.cfg, here are the important changes:

d-i     mirror/country          string enter information manually
d-i     mirror/http/hostname    string 192.168.1.22
d-i     mirror/http/directory   string /ubuntu
d-i     mirror/suite            string hoary
d-i     mirror/http/proxy       string

        host e400 {

                # fixed-address 192.168.1.181 ;
                option host-name "e400" ; }

       }

If your box doesn't have the option to boot from lan (like one of mine) you can make a boot disk that will do that part.

I am pleased to say that I was able to read, download, build, run, make the floppy in under 30 min.

"Etherboot does not (yet) offer support for PCMCIA cards." so the older laptops will have to wait.
