This weekend we did run a booth at Chemnitzer Linuxtage. As always, it was a joy to be at this event. We had great discussions and talks with guests and exhibitors, I also enjoyed a small number of lectures. The booth did run well, beside some quirks. Some pictures can be found here.
After Debian Squeeze was released last weekend, development will speed up again. I m experiencing since some time (out of the blue) spontaneous reboots of some of my dom0s on lenny/i386 (others don t have this effect). As result of this, I started rolling out linux-image-2.6.32-bpo.5-xen-686 from bpo and backported xen and xen-common from testing:
# dpkg -l grep xen grep bpo
ii libxenstore3.0 4.0.1-1~bpo50+1 Xenstore communications library for Xen
ii linux-image-2.6.32-bpo.5-xen-686 2.6.32-26~bpo50+1 Linux 2.6.32 for modern PCs, Xen dom0 suppor
ii xen-hypervisor-4.0-i386 4.0.1-1~bpo50+1 The Xen Hypervisor on i386
ii xen-linux-system-2.6.32-bpo.5-xen-686 2.6.32-26~bpo50+1 Xen system with Linux 2.6.32 on modern PCs (
ii xen-tools 4.1-1~bpo50+1 Tools to manage Debian XEN virtual servers
ii xen-utils-4.0 4.0.1-1~bpo50+1 XEN administrative tools
ii xen-utils-common 4.0.0-1~bpo50+1 XEN administrative tools common files
ii xenstore-utils 4.0.1-1~bpo50+1 Xenstore utilities for Xen
This fixed the problem of spontaneous reboots for all of the systems I have migrated . until now! Last week I tried this solution on my private system and it failed in some way.
A full dump of the syslog is also available. It looks like /etc/rcS.d/S03udev is hanging in some way .. the syslog for this looks like:
Oct 29 20:51:07 mordor kernel: [ 17.728120] Code: 04 00 00 00 00 83 3c 24 10 74 32 77 0c 83 3c 24 08 0f 85 9f 00 00 00 eb 12 83 3c 24 20 74 30 83 3c 24 40 0f 85 8d 00 00 00 eb 35 <0f> b6 01 8b 54 24 20 89 02 c7 42 04 00 00 00 00 eb 79 0f b7 01

The dom0 is there hanging in some way I don t have an exact way to get the system proceed from there usually I need to wait some seconds and pressing ^C after a while will get the box up.
Anyways I remember there are some problems with udev >= 150 and older kernels, which is also documented in the squeeze release notes. Maybe there is also a problem with older udev and newer kernels? But why is this combination working on other systems? Booting linux-image-2.6.32-bpo.5-686 works without any issue anyways, so it seems xen related. Any idea is appreciated!
UPDATE: I ve also reported this via #602109.
Alexander Wirt was so kind to upload the latest icinga (1.2) release to unstable. This will be the next candidate for lenny-backports-sloppy. In the last days I uploaded several (new) packages to backports.org:
Dear Gerhard,
one week after you have left us after your long fight and we payed one s last respects to you today, you hopefully may find your peace!
Thanks for all the things you have done for your family.
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. While I normaly don t care much about Ubuntu, I m subscribed to lauchpad.net for the packages I m involved within Debian. 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;

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.

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. 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.
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?
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 -

I m on vacation the 1rst two weeks of June in Manerba del Garda at Lago di Garda. If some dudes are around for beering / chatting / keysigning, feel free to contact me til Friday. What a happy day on the wedding anniversary of our civil marriage we got a great gift. Our favorite distribution released a new major version.Dear Stefan ‘Frost’ Mueller, it was a great pleasure to know you.
I’m really shocked, that such a nice and young man was pulled out of life out of the blue. Thanks for all the great things you have done for my family and me. Nothing more I can say at the moment other than ‘I hope we will see us again anytime wherever’.
Next.
