Thanks for all the things you have done for your family.

3DSupply with new Website?

cyco — Sun, 25 Apr 2010 09:02:38 +0000

Yesterday, my co-worker notified my about a promotion of 3DSupply and I recognized, that they have new design and you have also the choise to select from various models and colors for your shirts. I like the new site much more than the old.
For just speading they word, they offer to give a shirt (or any other item < 20 Eur) for free. So it seems to be a good idea to equip my dear wife, which is a teacher of catholic religion, with a new Jesus shirt.
Update: Today I got a reply from 3DSupply, stating that they deny the shirt request, cause I don’t have 10 posts in the last 6 month. As this is unfortunately true, due my always limited time, I can’t find this hard requirement in their terms. Looks like my blog doesn’t match their minimal requirements and I’m advised to equip my girls somewhere else with geekware. :o)

[fun] Integrate nagios users with system ones

cyco — Fri, 23 Apr 2010 08:10:53 +0000

While I normaly don’t care much about Ubuntu, I’m subscribed to lauchpad.net for the packages I’m involved within Debian.
Sometimes apears informative stuff there, which reminds me about my todos or just pointing me to real problems. Most of the time, I’m just ignoring the reports, as the are useless or just unrelated to me packages in Debian.
But in some cases the reports are just making my day.

[selfnote] Find the DUN Channel of your bluetooth device

cyco — Fri, 23 Apr 2010 07:59:06 +0000

In the last days, I replaced my Nokia E90 with a Nokia N97 mini. As I’m using my mobile from time to time to hook up to the internet when traveling, I thought I just need to replace the MAC in my /etc/bluetooth/rfcomm.conf and that’s it. As always … Murphy striked back. After debugging for hours I realized the DUN channel seems depending on the model.

You can discover your DUN channel something like:

# hcitool scan
Scanning …
3C:F7:2A:1A:4D:2A Cycophone
# sdptool browse 3C:F7:2A:1A:4D:2A | \
grep -9 “Service Name: Dial-Up Networking” | \
tail -10 | grep Channel
Channel: 22

So your /etc/bluetooth/rfcomm.conf should now look like:

…
rfcomm0 {
bind yes;
device 3C:F7:2A:1A:4D:2A;
channel 22;
comment “Cycophone”;
}
…

new nagios-plugins (1.4.14-1), now also installable on kfreebsd and hurd

cyco — Sat, 23 Jan 2010 13:03:06 +0000

Last night here at BSP I released nagios-plugins (1.4.14-1), which has a couple of fixes and enhancements. For more information, see the changelog.
The main change may, that with this version, the package should be installable on non-linux archs, where iputils-ping is not available. The downside of using inetutils-ping is, that its behavior is different from iputils-ping. As result of this, check_ping will timeout much often, even if there isn’t any problem and you will have false positives. As suggested long ago, at least on this archs, you should consider to replace the use of check_ping with check_icmp.

dkms rocks … or … how to get the Intel 82576 GBit NIC running on Lenny

cyco — Wed, 18 Nov 2009 20:07:18 +0000

We ordered a couple of the new HP DL160 G6, cause they can be equipped with a lot of RAM. Unfortunately it’s always the same with HP and the bandnew ProLiant 100 series … the driver for the NICs is missing/too old in the latest stable debian release. The DL160 G6 is shipped with a Intel 82576 GBit NIC, which isn’t recognized by Lenny, see also #522922.
I installed the system with another NIC installed (not really, but this is a way it works :) and wanted to get free the PCI-X slot again. So I did backport dkms and downloaded the latest igb driver. A short look into /usr/share/doc/dkms/HOWTO.Debian did advice me the way to create the DKMS driver package. Just after a couple of minutes I did roll out the igb-dkms_2.0.6_all.deb to the target maschine(s).
On the target systems I just installed dkms, the DKMS package and appropriate linux-headers and … sim, salabim … there was the interfaces. :)

OpenWRT WDS works like charm

cyco — Sun, 25 Oct 2009 22:20:18 +0000

A try with OpenWRT 8.09 in April to setup a WDS with additional AP functionality and encryption, like described in the documentation, failed. So I keeped with my halfbroken solution running on DD-WRT, which is going a bit too commercial these days in my eyes.
Now I have found time to try OpenWRT again for this purpose, since the issue was fixed really fast. I just did setup a stock 8.09.1 installation and then dropped the following into /etc/config/wireless:

config ‘wifi-device’ ‘wl0′
      option ‘type’ ‘broadcom’
      option ‘channel’ ’5′
      option ‘disabled’ ’0′
config wifi-iface
      option device “wl0″
      option network lan
      option mode ap
      option ssid “OpenWrt”
      option encryption psk2
      option key “keyforclients”
config wifi-iface
      option device “wl0″
      option network lan
      option mode wds
      option bssid 00:16:B6:19:63:C8
      option ssid “OpenWrtWDS”
      option encryption psk2
      option key “pskforWDS”

And guess what? It worked like a charm! So I could replace the odd DD-WRT boxes. Anyways ... does anybody have an idea where to find the sourcecode of anything > v23 SP1?

[selfnote] Cloning/Backing up NTFS systems

cyco — Fri, 18 Sep 2009 21:27:34 +0000

For some reasons, you may need to clone/backup NTFS based systems. Lets say your NTFS system is located at /dev/sda1 and /dev/sdb1 is a spare partition where you can store your image.

At first you need to boot a live system to take an image:

mount /dev/sdb1 /mnt/sdb1
dd bs=512 count=1 if=/dev/sda of=/mnt/sdb1/xp_vbox.mbr
ntfsclone -s -o – /dev/sda1 | bzip2 -9 -c > \
/mnt/sdb1/xp_vbox.img.bz2

To restore the image you just need:

mount /dev/sdb1 /mnt/sdb1
dd count=1 bs=446 if=/mnt/sdb1/xp_vbox.mbr of=/dev/sda
cat /mnt/sdb1/xp_vbox.img.bz2 | bunzip2 -c | \
ntfsclone -r -O /dev/sda1 -

P.S. If you are elective in germany, have a look at this!
