Klaus Knopper, Creator of Knoppix Talks to DistroWatch 201

Posted by Hemos from the good-things-small-packages dept.
An anonymous reader wrote to us about an interview with Klaus Knopper the author/creator of Knoppix. Knoppix is "a bootable CD with a collection of GNU/Linux software, automatic hardware detection, and support for many graphics cards, sound cards, SCSI and USB devices and other peripherals. KNOPPIX can be used as a Linux demo, educational CD, rescue system, or adapted and used as a platform for commercial software product demos. It is not necessary to install anything on a hard disk. "

    If I may ask, what made you decide to base this distribution on Debian [debian.org] as opposed to something like Slackware, RedHat, or even a Build Your Own Linux [linuxfromscratch.org] Distribution?

    In other words, was there any redeeming factors Debian had over any other distribution?

    • The problem with LFS is that after installing some 100 packages, you'll have a big mess because you don't know which file belongs to which package. Upgrading of packages is difficult, uninstalling is impossible.


      I've tried SuSE, LFS and Debian (in this order) and I have good reasons not to change my distro again.

    • In other words, was there any redeeming factors Debian had over any other distribution?

      I can't speak for Klaus, but I do know why if I were trying to do something similar I'd start with Debian:

      • Source code is available for everything in Debian, including the utilities used to produce the official distribution CDs.
      • Debian is a multi-lingual distribution, with an active translation team. Knoppix defaults to German.
      • It is legal to redistribute everything in both Debian proper and in the non-free supplement.
      • With 11 (and counting) supported architectures Debian is the most portable GNU/Linux distribution. If someone wants a non-x86 CD much difficult trailblazing is already there.
      • Anybody with technical chops can be a Debian developer. (Klaus maintains the cloop-src and cloop-utils packages.)
      • Sid (Debian "Unstable") is updated daily, making it easy to get the latest packages.

      Sure, other distros have most of these things. But Debian is the only one with all of them.

    • If I was going to create a distribution, I'd probably base it on Debian.

      If you base your distribution off a comercial Linux the people who created the base distro will view you as competition and say bad things about you to the press.

      The Debian development process is completely open and is garaunteed to stay that way. If you want, you can probably merge some code in the upstream source and save time.

    • As others have said, apt apt at.
      Ok , Granted Apt is *slowly* starting to become a sorta-reality on non .deb distros, but it's core to debian these days.

      The beauty of itis, I used the knx-hdinstall to install knoppix on my hard drive. Chucked in a sources.list file to point it at the local uni debian repository, typed in apt-get update then apt-get upgrade and *bLaMO!* --> all the latest updates to the packages just sorta turn up.

      Mandrake is red hat based, but you cant point it to red hat. Nor Red hat to mandrake. Neither to debian. But any debian based distro can (in theory) be pointed to deb.

      Too easy huh?
      • Long ago, yes, mandrake was based on redhat. this is simply not the case now. I think what you mean is mandrake is RPM based.

        Mandrake is quite a different animal now, but it does share the same package system. You are right, though, in that sometimes you can't use a redhat rpm to install on mandrake, but 99% of the time that is false.

    • If all you want to use this for is playing all sorts of movies, Movix [sf.net] is what you want. I tried it out a few weeks back, and now am actively "movixing" all my unburnt DivXs.

      Checkout the home page. In short, its a small (~5MB) linux distribution designed to be booted from a CD, with autodetection of video and audio, and automatically plays all the media files placed in the root directory of the CD. It uses Mplayer [mplayerhq.hu] to play the movies, so all formats supported by mplayer [mplayerhq.hu] (pratically everything!!) are supported by movix. All u do is put your "movixed" cd in ur drive, reboot, and watch the movie...all the software for playing it is right there on the disk.

      I have a laptop with a 250MHz processor, and Movix is the only way i can play Divx on it without dropping frames or loosing audio sync.

      If there were a DVD version of Knoppix with *every* free program you could possibly want to use installed - essentially Debian testing on a DVD - then maybe you could do without ordinary Linux distributions altogether. I'd certainly consider it, if I had a PC that was left on 24x7 and important things like mail and CVS on a central server.
      • So, what do you do when you realize they've patched a critical remotely exploitable bug right after you've burned or bought your DVD? Doh!
        • First, I'd hope that Knoppix doesn't boot with any services enabled, at least none that have externally open ports. So probably there won't be too many remote exploits. Second, if these do happen then just get a new DVD - they're cheap enough to burn, and changing the disc over is probably rather easier than updating packages, especially for a non-technical user. Third, even if the machine is rooted the potential for installing rootkits on a read-only medium is somewhat limited :-).

          Seriously, you could subscribe to a Knoppix service where they mail you a new DVD once a month or so, with more frequent deliveries in the unlikely event of a serious security hole.
          • I'm not sure if this would work. First of all, you *need* to write some stuff somewhere. I assume this is done on a RAM disk. So there's your opportunity for installing root kits. :) Of course, upon reboot, everything is clean again, but so is your data. So, unless you throw in your static webpages on the DVD too, a webserver is out of the question.

            Any mail client would need configuration settings, too. You want to configure your IMAP server everytime you reboot? Granted, you may not reboot often, but then you won't wipe those root kits off your RAM disk often, neither, will you? :)

            Bookmarking in your browser is out of the question, naturally, as is customizing your environment. You might be able to store some /home stuff on a floppy drive or another such removable storage medium, though. In that case, you better make sure you eject the medium each time you leave the keyboard, since you don't want your floppy infested with root kits. :P

            I'm sure most people can live with most of the inconveniences. But in every case, you will but more limited than you will be in an environment in which you use a harddisk for storage.

            Nonetheless, there are some most excellent uses for a bootable Linux distro, of course.
            • While I tend to agree that the potential to use this for a daily-use system is limited, nothing prevents you from booting the system from DVD and mounting /dev/hda1 to /usr and /dev/hda2 to /home (or whatever). Additionally, upon boot-up the system could read a configuration script from a CD-R, patching in-place any security holes and setting up your web server, IMAP server, etc.

              If no scripts are run from the hard drive on system initialization, the potential for installing root kits is limited. What good does it do to have the root kit sitting on the hard drive if it isn't installed when the system boots?

              LIS, probably impractical for a desktop system. But certainly doable for a server.
            • If you just want dotfiles, you can use a floppy for that. Any real 'work' I do is version controlled with CVS, so I'd just need to get a checkout to ramdisk or other temporary storage.

              I'm still not saying it would be entirely practical, just that it would be so nice if it were.
      • i suppose, but then you run into the problem of needing to release a new DVD everytime month or so to catch all the version updates in that free software. Either that or fall so far behind the curve that you won't even be able to see it.

        Still, Knoppix is great for at least one thing. It gives prospective Linux users an easy way to test the waters before they dive in by partitioning my hard drive.
        • If you're going to be installing a ton of systems on the same day, it might be worth it, though, especially if the process was automatic; run a script the night before which gets the latest versions of everything, organizes it into a DVD image, and burns it. Sure, it gets out of date quickly, but it's useful once.

          It gives prospective Linux users an easy way to test the waters before they dive in by partitioning my hard drive.

          Now that's dedication; I usually make them partition their own hard drives, not mine... :)
        • You could use Jigdo [in.tum.de]. That's what Debian uses. Instead of having to actually store huge CD or DVD images on you ftp site, Jigdo downloads all each file that supposed to be on the CD/DVD and then assembles them into an image file on the users system. One of the many advantages of this is that it's easy to update your images -- just upload the new files and change the .jigdo file that specifies which files are included in the image.

          That's why Debian can distribute uptodate CD and DVD images [debian.org] of "testing" and "unstable".

Remember Windows install process sometimes "insisting" that a piece of hardware is this or that, and your fighting to change it's mind?
      • What you describe sounds like Knoppix "Cheat Codes". These are simply parameters that can be entered at boot time to disable problematic detection of a particular component. So far, the only thing I've seen any problem detecting correctly has been CardBus on certain laptops.
    • I have used knoppix and have tried several other linux distro's in the past. I have to agree that the hardware detection is awsome. What I don't understand, and maybe someone can help me out here, is why distributions that are several years more mature are much more complicated to configure than knoppix. I understand that more advanced users would want the extra flexability but I truly believe linux would be more popular if the popular distro's all auto-configured as easily as knoppix. The only thing I have used that is close is the Mandrake install, and even that has some serious problems IMHO. Also I have seen short tutorials on installing knoppix to a hd but it seems a lot of people are trying knoppix out, maybe someone out there should right a true tutorial or maybe a util to install it to the hd automatically. It is still just a bit above my level.
      • There already is a way to do this.

      Obviously, Knoppix isn't really Linux if it does stuff for you automatically. As we all know, the only reason to use Linux is to have something to kill hours or days with while configuring arcane text files with no *understandable* documentation. By having this system just boot up and work, they've taken away the "Linuxness" of Linux itself. This is just a pale imitation of the Real Thing(tm).
      • If you want to kill hours or days configuring arcane text files, you're going to have to install on a hard drive. This is as close as you can get to read Linux without persistant storage, and they had to sacrifice unusability to meet this requirement. On the other hand, you can use Knoppix to boot the computer and get on the network so you can install stuff on the hard drive without having an installer getting in the way of editting your config files.

        And, honestly, I think it's kind of nice to let you use emacs under X to edit your XF86Config. I mean, once it's all set up, that's what you'd use, right?
    • Either because your prefered distro sucks, or because you haven't done an install in over 2 years.
    • I agree with you. Just last night I was trying to install Peanut Linux on an old Packard Bell 133Mhz, 48 MB RAM machine and configuring video display is a nightmare. I was up till 3 AM trying to configure it (selecting different options) but with no avail. Tried every different option from the manual and other listed options. Nothing works yet. Then I thought of trying out Knoppix (which I already use on my other machine 24/7 running squid-proxy, ssh and other stuff) and it came up without a hitch. Atleast now I know that the monitor and video card is usable with linux, just have to figure out what would be the right settings. I am gonna dig more and see if I can find settings used by Knoppix and then use the same with Peanut Linux (I am still a newbie :). I can't run Knoppix on this because it is a little slow and I need GUI.
      Only one thing is needed from Knoppix now: A stable install on HDD.

    This distro sure borns as a "demo" distro, but ive used it extensively and it rocks! Some of its uses are:
    • Put on a friends computer and show him/her the power of Linux and free software without modyfing his computer!
    • Boot a PC and figure out if the hardware its supported
    • Secure server? (Who can write in the cd?)


    I think the best point is that is Debian-based... and the hardware detection and configuration is awesome! Sure the debian guys can learn a bit... Free Software does not means impossible software, Knoppix!

      A bunch of things have to go into a ramdisk to be usable on a run-from-cd distro. That stuff can be altered, and the part you lose is the logs written to harddisk, which is kinda handy to have if something happens.

      anyway, it is neat to do. bblcd is easy if you read the directions. knoppix is neat and i gave it out to my students so they could keep their windows machines for their other classes, though the chance of them ever seeing debian in their future jobs is slim to none, and seeing Red Hat only slightly more likely (which is what the class was taught on).

  • Hardware auto-detection is obviously a major step in bringing linux to the masses. I don't think it can be underestimated (although I understand when people like the more hands-on approach, I'm a gentoo lover, myself.) I've been hearing more and more about Knoppix recently. Gnumed, an open source medical practice management solution project that i'm following is using it as a demo cd. Since Knoppix is customizable, I was wondering how many people have tried creating their "own" OS-on-cd. Computers are everywhere, so it would seem practical to have your own customized operating system and personal desktop on cd. Forget dealing with how other people set up their computers and just throw in your own cd. hmmm, i'm getting excited now. how cool would it be to whip out one of those credit card shaped cd's from your wallet, and amaze your friends.

    • You could try some to use one of the other small and fast desktops. WindowMaker is available (desktop=wmaker) and ICWM (desktop=icwm) is too. Just dont do TWM (desktop=twm) unless you want to show them 'how it used to be'

    • Has Open Office - runs slow off the CD - needs to be explained - otherwise a great demo disk

      This is a serious question: can you get Open Office to run fast when it's installed? I've never managed to get OOo to start up in less than 30secs or so on a reasonably (cel 500mhz) fast PC, and it's one of the reasons why I generally don't use it (stupid reason perhaps, but it really gets to me)

      Is this unusual? Can it start faster? (short of recompiling - I notice LFS has details on the OOo compile: 2hrs on a faster PC and way more harddisk space than I've got to play with)

    Knoppix is excellent as a demo distro, as an easy way to install Debian, but it's also a wonderful survival kit. When you're at a relative's (or friend's) house, you can take your Knoppix CD and a floppy (for the data). You can then hack&compile your projects, write documents (w/docbook or LaTeX). No need to ask them to install Emacs or anything else in their box.
    And the nice part is that it's customizable [gnome.org]! You can change the packages that go in the CD using apt-get (but you'll need 3 Gb of disk space for that!) I think I'll compile and include the PCTEL driver... It's one thing I'll really need! :-)

    But do as the article says: modify it after booting from the KNOPPIX CD. It uses a special compressed-loop module (available from knoppix.net [knopper.net]); the problem is that its stability seems to depend on which modules were compiled into the kernel [debian.org], and the kernel from the CD is known to work fine. I've tried to compile the cloop module for my kernel, but things didn't work (cp -a stalls).

    I have Knoppix running on an old Dell PII-233 as my MP3 player. I took out the hard drive, so it only runs on CD. I put in a 6-channal audio card hooked into the stereo and a video card w/TV-out (auto-detected, way cool). I run GNUMP3D on my Linux server, and now I can play all my MP3s through my stereo in the living room using the knoppix distro as the front end. (the wired keyboard/mouse isn't that elegant, I might get a wireless one eventually). The nice part is that it is pretty much silent when not in use.

    I am taking a Computational Physics class, and the professor prefers to use Linux for its ease in compiling and running programs. Unfortunately the only computer lab available was filled with windows machines, so we just boot the Knoppix CDs everytime we start class. Its fast and very easy to set up.
  • From the article:
    Some people (including me) are using Knoppix when shopping for a new computer. If the hardware is working fine and is all detected by Knoppix, the computer should be ready to run any brand of Linux.

    What a wonderful idea! I can see that this would make choosing a laptop much easier. No more guessing if the manufacturer added any weird proprietary stuff that Linux won't recognize. How many stores out there would let you do this though?
  • Me, and everyone I've shown it to, was simply blown away by Knoppix. And the deeper you look, the more impressed you are:

    * On the surface, it's just a perfectly user-friendly demo disk. Power on, CD in, KDE up. Now you may or may not like KDE (I don't like it), but it gives an instant "slick" interface that can easily hold its own against the whole windos world.

    * Then you realize it had a full-blown hardware autodetection, that works incredibly well - I've yet to see a machine where it doesn't come up fully automated and well-configured.

    * It also includes everything you need to go online, no matter what your connection is. It does DHCP, PPP, ISDN (very common in Germany), PPPoE for the ADSL people, even wireless if you want.

    * Then you start to wonder how all this stuff (900 packages, including all of OpenOffice, KOffice, more than a dozen small games, etc.) fits on the CD, and you learn that the guy wrote a compressed loop kernel module and everything is transparently decompressed when it's read from the CD!

    * Finally, it's 100% GPL. All of it is Free Software tools bolted together intelligently.

    • "* On the surface, it's just a perfectly user-friendly demo disk. Power on, CD in, KDE up. Now you may or may not like KDE (I don't like it), but it gives an instant "slick" interface that can easily hold its own against the whole windos world."

      Don't forget the desktop= option at the boot menu. My P1 laptop can just barely handle KDE, so I make sure to use desktop=icewm. There's also (*checks*) gnome, icewm, fluxbox, xfce, wmaker, and twm, plus runlevel 2 (text mode). That's directly from the boot help menu.
  • I give out these cds like AOL cds :)
  • I've been using Knoppix since it was mentioned on Slashdot earlier in the year and have found it very useful as a tool explain what linux can do to people who have not see it before.

    A couple of my friends are Windows Admins and I've managed to corrupt them enough to consider Knoppix as part of their tool kit, after all you can boot it, configure a network link and copy data off of the harddisk to a remote server if the normal OS will not boot.

    One of them has also used it to demostrate linux using a sony laptop and a projector at our local computer club [boxoffrogs.org.uk]. This meant he could show Openoffice opening Word and Excel files, Gimp and Internet access thus showing that Linux does make a viable desktop replacement.

  • The fact that he complained that you couldn't eject a mounted CD with your root FS on it just kills me.
  • I use it on Dells a lot, however on systems that don't have boot roms. An Etherboot server would be nice ;) Basically I use knoppix for getting random computers on the network. Formatting the hard drive and unpacking my prebuilt .tgz with everything already in it. Reboot, pop the cd and I've got a fully functional file server ready for production use in about 1 hour. Norton Ghost? We don't need no steenkin Norton Ghost!!
  • Will someone please make one of these that just boots to the seti client? Instant, non-destructive, painless borging!

    Move along. No content to see here.
  • Let me chime in with "Knoppix is great!" I used it just the other day to get info off a scrozzed WindowsME system before I wiped it.

    Something I'd like to see:

    . Self-customizing: Run a script that saves all settings and then generates an custom Knoppix ISO.

    . Using the custom ISO, you could boot, automatically mount samba/nfs shares, load up favorites, mount /home, etc...

  • (and I'm not mad about it)

    I have burned several Knoppix CDs for friends from my hard drive to my rather pokey internal CD-RW drive. However, since that's also a primary drive for me, I did not want to overtax it, and I now I will me making many more, so ...

    I bought a CD burner on sale from Target (for those outside the Target area, har har, see www.target.com -- large American retail chain, for the last few years has been working on its image as a modern general store up the totem pole from Wal-Mart). Then, burner unopened, I decided to trade it in when I saw they had a *duplicator* for $250. It's only one-source-to-one-target (not a fancy thing with internal drive or 16 target trays), but can copy a full CD in about 5 minutes. (Perhaps they do in some areas, but I've never seen CompUSA or such stores to carry duplicators -- I find it a strange but nice decision on target's part to stock them.)

    The drive is the 2nd generation (they were clearing out the 1st gen recently, I wish I had bought one of those instead), and though it has the currently popular "crystal black" look, I wish the top were not swoopy, so I could rest other things on it, which is perhaps the designers' point, but hey.

    e3works.com -- if you want to see it. bad site, though.

    Now: does anyone know how to make this drive work with Linux? I have tried two other external USB drives with Linux, and they have Just Worked with recent distros, Debian / Red hat / Mandrake. This one does not -- for instance, running cdrecord -scanbus does not find the drive. Yes, I have it switched to the "USB drive" mode rather than the Duplication mode. Anyone have tips? :)

    • Thanks for that link!! I'll probably hafta go out and buy one today now, ya big so-and-so... (/me grumbles about not having a job and no income)

      --As for getting it to work with Linux, since it's USB 2.0 try:

      # For USB 2.0:
      modprobe ehci-hcd
      # For USB 1.1:
      modprobe usb-ohci
      modprobe usb-storage

      --You can also try ' modprobe ' for: sr_mod, usb-storage, usb-ohci, ehci-hcd, sg, sd_mod, scsi_mod

      --I dunno tho, you might have to use a SCSI Generic device with cdrecord. Pop a disk in one of the drives and see if you can mount it on /dev/sgX or /dev/sdX.
  • I have burned ~8 copies of this for folks around here, used it to save some data off a friends new laptop (XP home) when it decided to eat itself.

    I literally don't leave home without it.

    I also did an install off the CD, and then just did an "apt-get update" ... Made me wanna cry tears of joy... Well. maybe not tears, but major warm fuzzies in any case.

    Kudos to Mr, Knopper!!!
