Habe auf der englischen Ubuntu-Liste ein HowTo für NetInstall der 
Ubuntu-Distribution gefunden. Jemand Zeit, das zu übersetzen und dann 
ins Forum zu stellen? Gerne dann auch fürs Wiki zu verwenden.


Some hints about Netboot install, in case it's of use to anyone else.

0. The scenario

One old Celeron 400Mhz with non-bootable SCSI CDROM, (kanga, This is the target for installation. It has a floppy

A DHCP server (roo,, using dnsmasq as the DHCP
server. roo has a pretty much home made Linux on it. I added tftp-hpa
to it, built from source.

Assumption: You're firewalled and will not expose services used for
this exercise to the world. You have a reasonable (ADSL) network

Server applications summary:


1. Setup DHCP-BOOT

On roo (the DHCP server):

o In /etc/dnsmasq.conf, add the line:


   This machine already serves an IP address to kanga via DHCP.

o Restart dnsmasq.

On roo:

o Download the Ubunto netboot tar file from


o Unpack into a suitable directory, e.g. /var/lib/tftpboot

   tar -xzf pxeboot.tar.gz -C /var/lib/tftpboot/
   chown -R nobody:nobody /var/lib/tftpboot

o Enable the tftpd server. Add the following as /etc/xinet.d/tftp.

   service tftp
         disable                 = no
         socket_type             = dgram
         wait                    = yes
         user                    = root
         server                  = /usr/sbin/in.tftpd
         server_args             = -v -s /var/lib/tftpboot
         only_from   =
         interface   =

   On some random machine:

o Build an Etherboot boot floppy. kanga (the installation target) has
   an 3Com 3c905 NIC

o Download and unpack Etherboot (etherboot-5.3.9.tar.bz2 from
   SourceForge in my case).

o Documentation from

o Make the boot floppy

   make bin/3c90x.zfd0

   (Subsititute your NIC type for 3c90x)

2. Start the install

o Boot the install target (kanga) from the etherboot boot floppy

o Marvel as Ubuntu is installed over the net.
