FAQ Linux LiveCD Router - How do I burn the CD ? Make sure that you burn the ISO image directly onto a CDrom. Burn the ISO file (as an image, not as data) with Nero or IMG Burn. - How to check the integrity of downloaded files ? At the download page, you can see [md5] links. These point to a page where the particular filename is printed together with a special string called 'md5 sum'. This is a 32 characters long text, which represents a check sum of the downloaded file. This checksum is used for several purposes, the most common is to assure your download was not corrupted. When md5sum of your downloaded file is different than the one published at the md5 page, then you can be 100% sure your file is damaged. In that case, try to download it again. In order to calculate the md5 sum of your downloaded file, use a special software. You can find it on Google, try searching for 'md5sum.exe' if you are in Windows. - I can't login ? The initial user/password is root/cdrouter Sometimes CDRs are defective, and the livecd is not burned properly. If you get "decompression error BIN.img" or similar error, you need to burn again your CD. - init: Id s2 respawning too fast: disabled for 5 minutes what can be done about this problem ? As of 2.0.26 console port is not supported (so you will not have this problem). This is due to the console port not finding your serial port 1. You can disable it it by commenting #s2:12345:respawn:/sbin/agetty -L ttyS1 9600 vt100 on /etc/inittab and restarting inittab with: init q - Can I install Linux LiveCD Router to a flash key ? - yes, as of 2.0.26 you can. - Extract cdrouter-2026.tar to your flash disk. - make the disk bootable by running (from linux) /boot/bootinst.sh - make the disk bootable by running (from windows) /boot/bootinst.bat - Can I install Linux LiveCD Router to hard disk ? - yes, as of 2.0.26 you can. - NEW. USB flash or SD memory card install. - Extract cdrouter-2029.tar to your disk. - make the disk bootable by running (from linux) /boot/bootinst.sh - make the disk bootable by running (from windows) /boot/bootinst.bat - NEW. HARD DISK install. - Extract cdrouter-2029.tar to your disk. Make a boot partition of 150MBytes only, type FAT32 Format and extract cdrouter-2029.tar to it mkdosfs -F 32 /dev/hda1 tar xvf cdrouter-2029.tar -C /mnt/hda1 - make the disk bootable by running (from linux) /boot/bootinst.sh - make the disk bootable by running (from windows) /boot/bootinst.bat - Is CDrouter much slower from USB ? In general, CDrouter is faster from USB than from CD. You just have to use the right USB key. Older devices (usually for USB version 1.1) are really slow and will give you problems. Even reading from such devices is slow. Newer devices work just fine with CDrouter, and those with 'ReadyBoost' are the best ones. We have seen booting from SanDisk Cruzer in less than 20 seconds, with no further slowdowns even during system operation. - What can make your USB flash key corrupted? CDrouter uses usb disks to boot only, and as a read-only filesystem to minimize problems. user and daemon programs use a regular hard drive or ramdisk for read-write use. Nevertheless see the following info about flash key corruption. In general, all filesystems are predisposed for data loss in bad situations. If you unplug the USB key from your computer before CDrouter finishes its shutdown procedures, or if you poweroff the computer while CDrouter writes something to the device, you may lost data or get the entire filesystem corrupted. FAT filesystem (widely used on almost all USB flash keys, MP3 players and Cameras) is the most vulnerable one. Anyway, if a filesystem gets damaged, it's not permanent. USB flash keys have individually erasable segments, each of which can be put through a finite number (for example 100 000) of write cycles before becoming unreliable. Conventional file systems like FAT or ext2 were originally designed for magnetic disks and as such rewrite many of their data structures repeatedly in the same place. The damaged segment can't be recovered. This type of corruption is permanent. To avoid filesystem damage, always make sure to shutdown or reboot correctly. If you boot CDrouter from a different device and use the USB key only as a storage medium, always make sure to unmount it properly before unplugging. If you can, use a journaling filesystem (like ext3) instead of FAT or ext2. And always use only devices with support for 'wear levelling', designed to distribute the re-writes across the medium, in order to prolong its life. - How to fix a corrupted filesystem? As mentioned in the previous section, the FAT filesystem is the most vulnerable one. If Linux detects corruption, it will remount it read-only to prevent further damage. To fix the problem, use: dosfsck -wa /dev/hdb1 Replace hdb1 by your own partition name. If you get an error message that there are differences between boot sector and its backup, don't worry about that, it's not a problem. The utility will simply skip that and will continue fixing all the other errors. - Steps to boot from CDrouter All new computers support booting from the CD, but almost all of them are looking for the operating system on the harddisk only. Your goal is to force your computer to use the CDROM instead. There are three ways how to do it: 1. The first one is supported on many motherboards. Your computer can allow you to boot from the CD once (only for this time) by pressing a special key (usually F11, F2 or F10) during the memory checks (very soon after the computer's power on). 2. The second method is to setup your box to permanently look for a boot-CD at first, and try to boot from the harddisk only if no CD is found. Again, you have to press some key during the startup (usually Del key), which will allow you to enter BIOS SETUP. There you can go through some menus and look for "Advanced settings", "Boot order" or "Boot options". Set CDROM as a first device and harddisk as a second one. All the keystrokes mentioned above are usually written at the computer's display at the time you can press them, or you may find them in the documentation of your motherboard. 3. Third way how to boot from the CD is by starting DOS and using linux.bat program from CDrouter.
