>Without monitor and keyboard (ie Headless)
Hello
You can try the following script and boot from floppy disk, or modify / remaster / customize Knoppix LiveCD:

debian-knoppix Starting SSH and Samba with floppyconfig
From: Chris Liechti <cliechti>
I recently ran into a little problem: i wanted to copy away data from a PC without screen and keyboard, but knoppix needs these two...
solution: make a bootfloppy with a knoppix.sh script on it that sets the passwords and starts the servers. so what you find here is the result of these efforts.
To use them, create a knoppix bootfloppy and copy these two on it.
Optionaly use the "hostname", "password" and/or "ip" boot options (see comments in knoppix.sh for more information)
Knopper: maybe are the "hostname" and "ip" kernel cmd line options also useful for the normal knoppix-autoconfigure? btw i did not see where the ip/nm/gw options are used in knoppix-terminalserver... they
are assigned to variables but never used?!? "hostname" could be useful, in case somebody wants to start several knoppix machines with servers
(apache, samba, etc)
have fun

# Start SSH and Samba servers.
#
# This script can be used on a floppy (bootsflopyp + floppyconfig) to start a
# server without touching the keyboard. The parameters can be given on the
# boot cmd line. The intention is that you can use this to rescue data from
# a PC over the network and that box does not even need to have a minitor or
# keyboard, just a Knoppix CD and this script on a floppy is used.
#
# Installation
# 1. Create a bootfloppy "cat /cdrom/KNOPPIX/boot.img >/dev/fd0" on Knoppix
# 2. Copy this file to te floppy, name must be "knoppix.sh"
# 3. Edit syslinux.cfg and append "floppyconfig 2" to all the "APPEND" lines.
# 4. Optionaly add "ip", "hostname" or "password" to the "APPEND" lines too
# 5. Try i out by booting this floppy with Knoppix CD in the CDROM
#
# Security advice
# The default passowrd is "secret". It should be overriden with the
# "password" option. but still then it's a default password. Default
# passwords are always bad... and insecure.
# The Knoppix home is exported read/write over Samba and the /mnt dir
# is accessible. Somebody with the password could fill the ramdisks or
# access the mounted partitions.
# Because of these limitations, you should not use this script on machines
# with internet connection. This script is intended for experienced users
# only.
#
# Samba is started for two reasons:
# - Easily copy files to a Windows or Linux machine.
# - Use "nmblookup Knoppix" to discover the machine from a remote computer,
# which is useful if the server started with DHCp and no monitor...
# And the host is found by Windows machines with the name "\\Knoppix".
#
# SSH is started so that one can login and mount drives, start NFS exports,
# whatever needed.
#
# Kernel command line parameters used:
# ip=x.x.x.x use static IP instead of DHCP, may also use "nodhcp"
# password=x use given password instead of "secret"
# hostname=x use given hostname instead of "Knoppix"
#
# Tips and tricks:
# - Start your VNC desktop with "vncserver -geometry 800x600". Don't start it
# as root but as knoppix user because of the ramdisks size.
# - Change syslinux.cfg on the bootfloppy so that it ony starts to textmode
# and make sure that it runs "floppyconfig". This means appending
# "floppyconfig 2" to the "APPEND" lines(s)
# - Always supply your own "password".
