Automating opening of hidden wireless net.

2009-12-17T12:22:47Z

When I booted the latest version of Knoppix on my HP Pavilion laptop it
recognized and informed me that I had a wireless net available. However it was
a "hidden" net. In the appropriate window I gave the name of the hidden net,
which emanates from my wireless Linksys router.

This is my wife's computer so I want to automate this process of net naming
and recognition, possibly in the rc.local file. Can anyone suggest the
necessary code?

Japanese KNOPPIX is a laucher of "virtual appliance" for Debian and Ubuntu

2009-12-14T20:31:06Z

Dear,

Japanese KNOPPIX6.2DVD includes "OS Circular" which is a kind of "virtual appliance".
http://www.rcis.aist.go.jp/project/knoppix/knoppix62DVD-en.html

OS Circular offers disk images of Debian and Ubuntu with LBCAS (LoopBack Content
Addressable Storage). It enables us to boot Debian or Ubuntu on KVM or KQEMU without installation.
The disk images of Debian and Ubuntu are updated weekly and allow to roll-back to previous images.
Please try. :-)

http://openlab.ring.gr.jp/oscircular/
Current Transferable OS (weekly updated)
Ubuntu 9.10 Karmic 20091109 -
Ubuntu 9.04 Jaunty 20090508 - 20091030
Ubuntu 8.10 Intrepid 20081107 - 20090501
Debian 5.0 Lenny 20081107 -

The optimization was presented at Linux Symposium 2009 (Montreal).

Fast Boot of KNOPPIX 6.2 with LCAT (Live CD Acceleration Tool kit)

2009-12-14T20:22:09Z

Hello,

We customized Japanese KNOPPIX6.2 DVD with LCAT (Live CD Acceleration Tool kit).
http://www.rcis.aist.go.jp/project/knoppix/index-en.html

The boot time of KNOPPIX6.2 with LCAT was 3 times faster than the original on
ThinkPAD T400. It was 50 seconds on LCAT and 140 seconds on original. The video
was opened at YouTube. Please visit.

Re: knoppix 6.0.1: rc script for run level 2

2009-12-12T09:18:29Z

Dear Mr. Knopper,

I added my line in /etc/rc.local just before "exit 0". But the script
was not executed.
The kernel line in grub is:

/boot/isolinux/linux ramdisk_size=100000 init=/etc/init lang=us
apm=power-off vga=normal initrd=minirt.gz nomce BOOT_IMAGE=linux 2

Can this be the reason ?

Thanks.

Re: knoppix 6.0.1: rc script for run level 2

2009-12-11T09:06:10Z

Hi,

For reasons if independence from customized installed software that
usually adds runlevel scripts which not everybody wants to have started
automatically, and also boot speed reasons, Knoppix does not use the
/etc/rc*.d directories, they are commented out in /etc/inittab. If you
just want to start another /etc/init.d/* script, just add an entry in
/etc/rc.local, which will be executed at the end of autoconfiguration
and before X starts.

The sequence of bootscripts is:

1. /init on the initial ramdisk (mounts all necessary ramdisks, overlay
etc, so init sees a writable system)

2. /etc/init.d/knoppix-autoconfig (started by the real init via
7etc/inittab)

3. /mnt-system(the boot medium)/KNOPPIX/knoppix.sh if present, and /etc/rc.local

4. /etc/init.d/knoppix-startx (in case of runlevel 5).

Regards

Re: knoppix 6.0.1: rc script for run level 2

2009-12-11T08:46:42Z

Hello,

Thank you for the information.
/etc/rc2.d contains many links to scripts int /etc/init.d by default.
But non of them are executed upon boot completion and entering run level 2.

Should I change inittab for this purpose ?
Or maybe put the link to the script in rcS.d

Thanks.

Re: knoppix 6.0.1: rc script for run level 2

2009-12-11T01:08:50Z

Hallo Zvi,

I guess you have already made the script executable (chmod 755). Then the script should be linked to /etc/rc2/S99rc2. Important is the S##. It means that the script is _S_tarted after all scripts with smaler numbers have been executed. In fact the order of execution is the same as shown with ls -l.

cd /etc/init.d
ln -s rc2 /etc/rc2.d/S99rc2
ls -l /etc/rc2.d/S99rc2

lrwxrwxrwx 1 root root 3 2009-12-11 09:59 /etc/rc2.d/S99rc2 -> rc2

Knoppix is derived from debian, docs are here:
http://www.debian.org/doc/

Runlevel management is here:
http://www.debian.org/doc/manuals/debian-reference/ch03.en.html#_the_runlevel_management_example

With kind regards

Achim

PS: I hope this all is still right, because the starting procedue in UNIX is about to change due to slow booting times.

You might want to add this:
echo "Hello from knoppix" > /var/log/hello

So you can tell if the script was run even if the echo output scrolled
out of the terminal too fast.

Names of scripts in /etc/init.d do not determine in which runlevel they
should run, they must be symlinked from the actual runlevel directories.
Give your script a more descriptive name like /etc/init.d/hello,
then set a symbolic link from /etc/rc2.d to it:
cd /etc/rc2.d
ln -s ../init.d/hello S90hello

The name prefix "Sxx" of the symlink indicates that the script will be
called with parameter "start". The number "xx" specifies the order in which
scripts will be called. "Kxx" symlinks will call scripts with parameter
"stop".

Greetings,
Chris

knoppix 6.0.1: rc script for run level 2

2009-12-11T00:18:01Z

Hello,

I installed knoppix 6.0.1 (kernel 2.6.28.4) on a USB disk. The kernel line
in grub
contains "BOOT_IMAGE=linux 2" to launch knoppix in text mode only.

In order to run a script upon entering to run level 2 I wrote a script named
rc2 in /etc/init.d:

#!/bin/sh
echo "Hello from knoppix"
sleep 10

But upon entering runlevel 2, this script is not executed.

What am I doing wrong ?

Thanks.

Answering my own post. It seems that the problem was due to the knoppix-data.img is sitted on top of the ntfs, and the ntfs itself is somehow corrupted. I booted on Windows, and scheduled a file system check. Upon reboot, the chkdsk fixed all the file system errors, and as result mounting knoppix-data.img as ext3 does not hang anymore.

As for why knoppix is mounting knoppix-data.img as ext2, it is a matter of historical reason than anything else, I think.

knoppix 6.0.1 mount knoppix-data.img as ext3

2009-12-03T02:56:28Z

I am using knoppix 6.0.1 but I have upgraded the kernel to 2.6.31.6. During the upgrade I also added aufs2 as the module to support unionfs.

Now everything is working fine but I noticed that every time system reboots, knoppix will spend significant time 'fsck' the 2GB knoppix-data.img which I created. A view into minirt.gz revealed that 'init' is mounting knoppix-data.img as ext2 file system. To reduce the 'fsck' time, I modified things accordingly to allow for the DATA image to be mounted as ext3 ( ie I removed '-t ext2' in the mount data section ).

But after this change, I noticed that the first time it will boot correctly but after a reboot, it will hang the entire system at boot stage.

Is it the way I did is wrong or is the aufs2 is just not able to work together with ext3 file system ? Anyone has comments on it ?

Regards.

This comes from the kernel-internal decompression. Please make sure this
is enabled in your .config:

CONFIG_ZLIB_INFLATE=y

> No compiling errors.

I'm happy to hear this. There have been a lot of API changes in the
block layer in the recent kernel releases, so I was afraid of having to
change cloop again for kernel 2.6.32, but apparently this is not
necessary.

The zlib functions are needed during runtime, and must either be present
in the static kernel part, or loaded as a module. If none of this is
provided, then you get the message you got.

Kernel 2.6.32

2009-11-26T08:20:33Z

I think 2.6.32 is going to come out soon.

I did a preliminary test and it seems that something has changed with zlib:

insmod: error inserting 'cloop.ko': -1 Unknown symbol in module
linux:/home/max/cloop-2.631# dmesg -c
cloop: Unknown symbol zlib_inflateReset
cloop: Unknown symbol zlib_inflateInit2
cloop: Unknown symbol zlib_inflate
cloop: Unknown symbol zlib_inflate_workspacesize

No compiling errors.

Hi Klaus,
No, the use of the xmodule=fbdev cheat code does not help.
If I press the Ctrl+Alt+F1 when in a lxterminal window,
the characters: ";7P" get displayed, ";7Q" for Ctrl+Alt+F2, ...
Interestingly "sudo setxkbmap us" fixes it.
So since I used this fix in the init boot script to get the us keyboard working
on your German beta it may have been broken already on the beta.
Hope this helps,
Gilles

Frankly, I don't know yet. I may have updated some xorg-related
packages. But VT switching still works for me on intel chipsets, so this
rather makes the nv xorg video module a suspect.

If booting in framebuffer mode (xmodule=fbdev), does this change
anything?

Yes, Debian uses /etc/default/console-setup for defining the keyboard
layout for any keyboard detected by udev/HAL. This was the fix for the
wrong keyboard layout in the almost-released version from 15th and 17th
november (that made it to some mirrors anyways).

But I don't think it is related to the VT switch issue.

I'm not aware of having changed the X-Servers setting between these
versions. Does "sudo chvt 1" work for you?

The only reason I could think of why this happens is that the chipset
has a broken framebuffer handling (NVidia cards?) and for this reason,
ChangeVT is automatically disabled.

Yes, this is a limitation introduced when switching from ext3 to reiserfs
in 0wn. If you manually create a reiserfs partition you have to mount
it once in rw mode to fully initialize it.

You are right that this is no acceptable fix, because
check_partition_empty() must not change the partition
(as much as this is possible at all).

The real fix could be something like that:
1) save partitions before manual partitioning
2) check for new reiserfs partitions
3) try to mount them rw, iff ro mount failed

Erik

Your fix is OK, you could also just have removed the blockdev line(s)
completely.

The real problem here is that after partitioning and formatting,
reiserfs needs to be mounted rw at least ONCE for creating the journal,
thus making it a valid reiserfs filesystem. gparted does not do this on
its own. Mounting reiserfs with the device set read-only is impossible
if the filesystem was never initialized properly. Reiserfs "repairs"
itself to a consistent state during mount without needing fsck, but this
does not work if the underlying device is read-only.

The blockdev commands are there primarily to make sure that filesystems
are never changed during the test-only phase, which is especially
important if the OS running before you started Knoppix was shut down to
hibernate, and the filesystems are in an inconsistent state. But
actually, this is over-cautious, since no other utility (especially the
filemanager) really checks for that.

Hi there,

The HDD install of the latest version of Knoppix wasn't working for me: my scenario was
a "I want to create the partitions myself and then you'll see I have what's needed to
install". Besides many other partitions, I created (with gparted) a swap and a free (and
big enough) reiserfs partition. Yet, 0wn (the installer) kept telling me I didn't have what
is needed to make an installation. Checking the logs, I found out that there was a "mount"
failing. After looking at the code, I found out that it was happening (in my case) twice
in the code. Here's how I've fixed it (sorry for not providing a diff):

at /usr/share/0wn/0wn-partitioning :

1) on check_partition_empty(), change
- blockdev --setro "$1"
to
+ blockdev --setrw "$1"

2) on check_partition_big_enough(), change
- blockdev --setro "$1"
to
+ blockdev --setrw "$1"

I'm confident that this is *not* the right way to fix the problem, but it surely was
how I worked around the issue and now have a machine with Knoppix being

Klaus, you may want to take a look at how Finnix handles it in its
autoconfig. It has a loop of LUKS dm-crypt, LVM and md-raid checks,
and will repeat the process as long as it has something new to do.
That means it should be able to handle setting up stacked block
devices in any combination (LVM on top of LUKS on top of a RAID setup,
for example). Once it has run out of new block devices to set up, it
moves on to scanning block devices using its equivalent of
scanpartition.

I've had that code in there for a few major versions now, and I've yet
to see it do anything wrong on complex setups.

I would like to point out another detail. The combination of black hills together with grey rain clouds creates an atmosphere that I do not like to make Knoppix 6.2.x also a better user experience.

How do you think about perception from other landscapes/sceneries?

Actually, I do like the picture as it is, because it is much less
intrusive than the screaming "green-blue-yellow" pictures from other
desktops.

A background picture should in my opinion really be something in the
"background", not a "front picture". A decent not too light color with
not too much contrast is best, since the applications running in front
have enough color and contrast.

It's true, I'm quite used to my choice of backgrounds in the most recent
releases being rated as "boring", but actually, for me they are more
"real world" than the candy-colored artificial rendering most
distributions use today.

Anyways, if you don't like the picture, just feel free to exchange
KNOPPIX/background.jpg on your DVD or flashdisk. :-)

I'm not sure about this.

/usr/sbin/scanpartition checks for softraid partitions using dmraid.
This SHOULD load the corresponding modules.

vgchange could load dm-mod, if block devices in /dev trigger this, but
there is a recursive dependency because udev does not create the devices
unless the module is loaded.

Would there be any disadvantage or possible damage if dm-mod is loaded
by default? I'm thinking about re-formatted partitions that once had a
volume group, but were formatted with a different filesystem later.

Is there a chance that vg* can destroy an existing filesystem?
