With the latest release the Wireshark Project decided to make the Qt GUI the default interface. In line with Debian’s Policy the packages shipped by Debian also switched the default GUI to minimize the difference from upstream. The GTK+ interface which was the previous default is still available from the wireshark-gtk package.
You can read more about the new 2.0.0 release in the release notes or on the Wireshark Blog featuring some of the improvements.
update: Wireshark 2.0.0 will be available from testing and jessie-backports in a week. Ubuntu users can already download binary packages from the Wireshark stable releases PPA maintained by the Wireshark Project (including me:-)).
Debian has switched to FFmpeg in testing in July but the work on the package did not stop at that point. After careful testing we can now provide official packages for Jessie users through jessie-backports. See installation instructions here. FFmpeg becoming available in jessie-backports also enabled us to provide Kodi from Debian in the same official repository.
Thanks to everyone in the Debian Multimedia Maintainers team, especially Andreas Cadhalpun who is also upstream developer at the FFmpeg project, Reinhard Tartler who maintained FFmpeg then Libav then FFmpeg again in Debian for long years and everyone else I could not name here but helped making this possible!
The Linux Kernel Oops website collects kernel errors from all over the World helping kernel developers finding issues occurring in the wild but they cannot help if no one sends reports to them.
The Kerneloops client used to be part of Debian releases but it has been removed from the archive due to not working with the new collector site.
When I started observing oopses on my machine I first thought of submitting a bug against the linux package in BTS, but looking at the numerous bugs opened already I looked for a more automated solution which would also help others. Reviving the kerneloops package involved switching it to the new submission URL, fixing a few memory allocation bugs in C (this is the first package I found using Valgrind by default for running tests) and ensuring that upstream was still active. The last step took the most of the time but finally Anton Arapov kindly accepted my patches and everything was set for the new upload.
The package is now available from unstable and if you feel so (especially if you experience oopses) please give it a try and report any problems you find. I’m also happy to receive success stories about oopses fixed after discovering and collecting them with the client.
Debian was not generally seen as a bleeding-edge distribution, but it offered a perfect combination of stability and up-to-date software in our field when we chose the platform for our signature verification project. Having an active Debian Developer in the team also helped ensuring that packages which we use were in good shape when the freeze, then the release came and we can still rely on Jessie images with only a few extra packages to run our software stack.
Not having to worry about the platform, we could concentrate on the core project and I’m proud to announce that our start-up‘s algorithm won this year’s Signature Verification Competition for Online Skilled Forgeries (SigWIComp2015) . The more detailed story can be read already in the English business news and is also on index.hu, a leading Hungarian news site. We are also working on a solution for categorizing users based on cursor/finger movements for targeting content, offers and ads better. This is also covered in the articles.
László – a signature comparable in quality to the reference signatures
The verification task was not easy. The reference signatures were recorded at very low resolution and frequency and the forgers did a very good job in forging them creating a true challenge for everyone competing. At first glance it is hard to imagine that there is usable information in such small amount of recorded data, but our software is already better than me, for example in telling the difference between genuine and forged signatures. It feels like when the chess program beats the programmer again and again.
I would like to thank you all, who helped making Debian an awesome universal operating system and hope we can keep making every release better and better!
This problem has been bugging me for a while: how to setup my Kodi based home cinema to automatically mount an optical media ?
Turns out the solution is quite simple, now that Debian has switched for
systemd. Just add the following line to
/dev/sr0 /media/bluray auto defaults,nofail,x-systemd.automount 0 2

Ending an era of shipping Libav as default the Debian Multimedia Team is working out the last details of switching to FFmpeg. If you would like to read more about the reasons please read the rationale behind the change on the dedicated wiki page. If you feel so be welcome to test the new ffmpeg packages or join the discussion starting here. (Warning, the thread is loooong!)
Erlang lets you write applications supporting zero downtime by switching one live system to another running a different application version converting the application’s state on the fly to the new representation. Debian packages however can have only one installed version on a system which prevents using Erlang’s hot-upgrade feature easily.
Engineers at Yakaz (Jean-Sébastien Pédron) came up with a nice solution by creating separate directories for each application release and creating .deb packages for managing the transitions. I had to solve the same problem recently and found that the erlsvc Perl application they created needed a few patches to be usable with latest Erlang and other packages and with the changes it worked perfectly. Yakaz was not interested in accepting the patches and developing it further, but let me continue the maintenance. Please find the updated erlsvc application under my GitHub account and feel free to submit patches if you find something to fix in it.
I have also packaged erlsvc as an official Debian package and it is waiting in the NEW queue for being accepted. When it enters unstable you will have to make very little effort to make your applications hot-upgradeable on Debian!
update: The package has now been accepted to the archive. Thanks to the FTP Masters for their hard work!
The well known XBMC Media Center has been renamed to Kodi with the 14.0 Helix release and following upstream’s decision the xbmc packages are renamed to kodi as well. Debian ships a slightly changed version of XBMC using the “XBMC from Debian” name and following that tradition ladies and gentlemen let me introduce you “Kodi from Debian”:
Kodi from Debian main screen
As of today Kodi from Debian uses the FFmpeg packages instead of the Libav ones which have been used by XBMC from Debian. The reason for the switch was upstream’s decision of dropping the Libav compatibility code and FFmpeg becoming available again packaged in Debian (thanks to Andreas Cadhalpun). It is worth noting that while upstream Kodi 14.0 downloads and builds FFmpeg 2.4.4 by default, Debian ships FFmpeg 2.5.1 already and FFmpeg under Kodi will be updated independently from Kodi thanks to the packaging mechanism.
The new kodi packages are uploaded to the NEW queue and are waiting for being accepted by the FTP Masters who are busy with preparing Jessie for the release (Many thanks to them for their hard work!), but in the meantime you can install kodi from https://people.debian.org/~rbalint/ppa/xbmc-ffmpeg/.
Happy recovery from the holidays!
update: I have updated the Kodi version to 14.2 in the xbmc-ffmpeg repository also updating FFmpeg to 2.6.1.
The packages can be used with Jessie, but unstable and experimental repositories also have to be enabled due to some dependencies missing from Jessie but present in unstable/experimental.
update 2: Dominique Dumont wrote a nice how-to about automounting optical media (CD/DVD) using Kodi on Debian.
update 3: Kodi is now available from jessie-backports, testing and unstable. Please use the packages from the official repositories instead of my temporary one which contains outdated packages and will be deleted.
Running Wireshark for Android has been an dream for a long time. Now it became a reality!
Wireshark running on Android using Lil’Debi
You only need a rooted Android device with ~2GB free space, Internet connectivity and some patience to follow the steps below.
- Install Lil’ Debi from
Google Play or F-Droid. Lil’Debi will install a Debian root file system in a loop device separately from the Android file system allowing us running Debian side-by-side to the Android apps.
- Start Lil’ Debi and create the Debian system with 2000 MB image size. We will need some space for Wireshark, the graphical interface Wireshark depends on and for the capture files.
- Start the newly created Debian system and log in to it. You will see the error message “bash: [: : integer expression expected”, but you can continue.
- Now run the following commands at the command line to install all the packages Wireshark will need:
# some important directories are missing from the PATH by default
# we will start an X server later
# install wireshark an a few things to make it nicer
apt-get install openbox gnome-themes-standard tshark wireshark
# gnome-settings-daemon depends on plenty of packages we don't need now,
# but we need gnome-settings-daemon for the GNOME theme to be applied
apt-get install --no-install-recommends gnome-settings-daemon
- To run graphical applications from the Debian chroot we need to set up an X server on Android because Android uses a different method for presenting the GUI. XServer XSDL is available from Google Play and from SourceForge. Install and start it. It will show the display it is serving which will most probably end with :0, so the DISPLAY environment variable we set before is correct. (If there is an other number after the “:”, fix your DISPLAY variable.)
- Start the openbox window manager, gnome-settings-daemon and finally wireshark in capturing mode:
# if you would like to have bigger menu fonts skip starting gnome-settings-daemon
wireshark -k -i wlan0
- Switch to the X server to see wireshark starting up, close the warning dialogs start capturing traffic!
I tested the tests above using a Nexus 7 (Asus 2013 version) running CyanogenMod M7, thus root access was granted by default, Lil’ Debi 0.4.7, and XServer XSDL 1.11.14.
update: Lil’ Debi has apparently been removed from Play Store.
