| − | === [[debian-knoppix]] Starting SSH and Samba with floppyconfig ===

| − | ==== 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)

| − | # 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".
