Knoppix Tips

Introduction

These tips relate to using the Knoppix live CD (version 4.0.2) available at http://www.knopper.net/knoppix/

Mounting knoppix.img

If you have created a persistent knoppix disk image on your compact flash, the persistent image is created as knoppix.img on your compact flash card.

You can access it without booting from a knoppix CD, by mounting it as a loop device.

• mount /mnt/sda1/knoppix.img -t ext2 -o rw,loop=/dev/loop1 /mnt/knoppix

Create a similar image file on a FAT16 or FAT32 and mount it as ext2 with the following

• dd if=/dev/zero of=/mnt/sda1/my.img bs=1 count=100M
• mkfs.ext2 -m 0 /mnt/sda1/my.img
• su -
• mkdir /mnt/knx
• mount /mnt/sda1/my.img -t ext2 -o rw,loop=/dev/loop2 /mnt/knx
• chown -R knoppix:knoppix /mnt/knx

Cheat Codes

Various boot options can be selected using Cheat Codes. The complete list of cheat codes are included on the CD under /KNOPPIX/knoppix-cheatcodes.txt or at ftp://ftp.uni-kl.de/pub/linux/knoppix/knoppix-cheatcodes.txt

Language Settings

British English

knoppix lang=uk keyboard=uk xkeyboard=gb tz=Europe/London

Troubleshooting

MySQL

Fails to start with message connect to server at 'localhost' failed

If you start syslog with Menu | KNOPPIX | Services | Start SYSLOG you will see MySQL fails to recognise an 'old_passwords=1' option. This option is set in /etc/mysql/my.cnf - commenting out this option fixes the problem.
