TFTP + DHCP Server setup for net-installing Ubuntu

Enable network booting from BIOS and move it above the rest.

Install Ubuntu Server 10.04 LTS or better on a VM (VMWare or VirtualBox works).

sudo apt-get update && apt-get dist-upgrade
sudo apt-get install tftpd-hpa dhcp3-server openbsd-inetd tftp-hpa

Backup and replace /etc/dhcpd3/dhcpd.conf with the file below the divider.

Download the correct netboot package:

etc.

mkdir -p /tftpboot/lucid-64bit
cd /tftpboot/lucid-64bit ; tar -zxf ~/netboot.tar.gz

do the same for the 32 bit packages if you have any older machines.

Boot the PC once over the network. It won't. Note down the IP address.

Edit /etc/dhcpd3/dhcpd.conf and change the following for your env:
 hardware ethernet 00:1E:8C:5C:7D:42;
 fixed-address 192.168.1.100;
 next-server 192.168.1.64;
 filename "lucid-64bit/pxelinux.0";
 option routers 192.168.1.254;
 option domain-name-servers 192.168.1.254;

replacing the hardware ethernet with the PC's MAC, modify fixed-address to a value you would like to hand out to the machine, next-server, option routers and domain-name servers should point to the existing ADSL router etc.

Restart the dhcpd daemon. Make sure inetd is running, if not invoke the daemon.

This step is very critical: PLUG THE FRIGGIN' CABLE TO THE EEE...

Reboot. Enjoy.
Then it's a matter of spending a couple of hours while it downloads everything over the net and installs.

#  option routers rtr-239-0-1.example.org, rtr-239-0-2.example.org;
#}

# This declaration allows BOOTP clients to get dynamic addresses,
# which we don't really recommend.

#  range dynamic-bootp 10.254.239.40 10.254.239.60;
#  option broadcast-address 10.254.239.31;
#  option routers rtr-239-32-1.example.org;
#}

# A slightly different configuration for an internal subnet.
#subnet 10.5.5.0 netmask 255.255.255.224 {

#  max-lease-time 7200;
#}

# Hosts which require special configuration options can be listed in
# host statements.   If no address is specified, the address will be
# allocated dynamically (if possible), but the host-specific information
# will still come from the host declaration.

#host passacaglia {
#  hardware ethernet 0:0:c0:5d:bd:95;
#  filename "vmunix.passacaglia";
#  server-name "toccata.fugue.com";
#}

# Fixed IP addresses can also be specified for hosts.   These addresses
# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
# BOOTP or DHCP.   Hosts for which no fixed address is specified can only
# be booted with DHCP, unless there is an address range on the subnet
# to which a BOOTP client is connected which has the dynamic-bootp flag
# set.
#host fantasia {
#  hardware ethernet 08:00:07:26:c0:a5;
#  fixed-address fantasia.fugue.com;
#}

# You can declare a class of clients and then do address allocation
# based on that.   The example below shows a case where all clients
# in a certain class get addresses on the 10.17.224/24 subnet, and all
# other clients get addresses on the 10.0.29/24 subnet.

#class "foo" {
#  match if substring (option vendor-class-identifier, 0, 4) = "SUNW";
#}

#shared-network 224-29 {
#  subnet 10.17.224.0 netmask 255.255.255.0 {

#  subnet 10.0.29.0 netmask 255.255.255.0 {
#    option routers rtr-29.example.org;
#  }
#  pool {
#    allow members of "foo";
#    range 10.17.224.10 10.17.224.250;
#  }
#  pool {
#    deny members of "foo";
