Ubuntu 9.10 (Karmic Koala) and songbird

Categories: Linux, Software
0 Responses

After an upgrade to Ubuntu Koala Karmic (9.10) I noticed my songbird would not start, running it in the shell showed some gstreamer errors. Through a google search I found the solution:

export LD_BIND_NOW=1
/usr/share/Songbird/songbird

seems to fix the startup issues …

Accessing your Reiserfs, XFS, lvm, dm-raid, … partitions under Windows

Categories: Linux, Software, Windows

From time to time I also boot Windows which is still installed on a partition on my desktop. The Microsoft operating system does not have support for any Filesystems that are nowadays mainstream on Linux. I know you can access Ext2/3 with ext2 installable file system for windows but that does not help to access my XFS homedirectory on my desktop. As a workaround I was thinking to try and mount them with VMware running linux but since this did not seem to work a friend gave me the tip to try coLinux and this seems to be pretty easy:

  • install coLinux (see the wiki and docu) and make sure it can access the network
  • add in the config file for colinux a line:
  • cobd2=”\Device\Harddiskx\Partitionx”
    with x the harddisk number and y the partition number (both start from 0, just count the partitions, needs some experimentation perhaps …)

  • under the linux image you can just mount it by
  • mount -t xfs /dev/cobd2 /mnt/mountpoint
    and after that add it to your fstab file.

  • share /mnt/mountpoint using samba (see plenty of howto’s if you don’t know how to do this)
  • Now you can access your linux partitions through the colinux samba share

SD card photo recovery

Categories: Linux, Software, Windows

Today there was a small crisis at home. My parents and sister came back from a week vacation and when they tried to copy the pictures from the trip on the -Windows- pc, all of the sudden they got read errors from the cardreader. Afterwards when looking at the SD card with another windows pc and the camera itself it was only possible to see 45 pictures on the card (While the total amount should be around 180). I put the cardreader in my linux pc and there I could see 155 pictures, already better than 45 but still no 180 (You could even see it in the numbering, there was a gap between 45 -coincidential or not the amount I could see on Windows- and 79, so still ~30 missing). So I went searching for recovery tools and found a nice (cross-platform!) tool called photorec, a tool included with testdisk which is free data recovery software, open source and gpl’ed. (On Ubuntu: ‘apt-get install testdisk’, this includes photorec) With this tool I was able to recover 145 pictures from the card (not all pictures, but the missing pictures between 45 and 79 were there, so in the end I got all pictures from the card). Now only to figure out what caused this weird behavior, the card itself or the “cheap” cardreader …

Installing lightning 0.8 plugin for thunderbird on ubuntu hardy

Categories: Linux, Software
0 Responses

When installing the latest version of thunderbird lightning plugin (version 0.8) which can be found on the official plugin pages for thunderbird, you will notice that the screen looks all messed up. This can be solved by installing the libstdc++5 package. This is needed because the ubuntu developers compile against a newer version than the lightning plugin.

sudo apt-get install libstdc++5

Fosdem 2008

As so many people already posted bits and pieces of their visit, here also a short overview of my visit to Fosdem 2008:

On Saturday I went to see the opening talks, I was really impressed by the “tux with shades” presentation, it was nice to hear that movie studios are completely switching over to/are running on Linux for creating special effects in movies. In the afternoon I attended a very enlightening presentation about SElinux on CentOS, I had already worked with it a bit, but never really had time to look how it exactly works. I had a short stop at the Mozilla dev room – dubbed sauna.fosdem.org because of the heat!- with a presentation about Thunderbird and to end the day a presentation about Dstat which looked also very interesting to monitor various server performance issues.

On Sunday I did the whole main track about virtualisation, the xen one was not that interesting since it did not go very technical and I had already seen a more in depth one last year. The virtualbox presentation gave a nice overview of the buildup and future development of the software and the openQRM presentation was interesting because it was my first encounter with the software, like Wonko already mentioned definately worth a look. In the afternoon I attended an LVM2 novelties presentation. Afterwards I attended the webscarab presentation: a proxy which enables you to inject code in GET and POST parameters in realtime. I will certainly test this one as security is also part of my job. And to end the day I attended the presentation of CentOS 5 virtualization – which contained actually more topics like how to fastly deploy virtual machines and maintain several of them at once. I had a very nice discussion about this afterwards with some CentOS developers which actually encouraged me more to try out puppet in the near future (not really in the talk, but according to what I read and they told me one of the best tools for mass-maintaining a lot of servers) .

I met a lot of acquaintances (and then to say some years ago I knew almost nobody there) and also got to know a few interesting new people. I’d like to thank the organisers of Fosdem for making it again a splendid event!

Samba Team Receives Microsoft Protocol Documentation

Categories: Linux, Software

Around this time you can expect cold temperatures but apparently even hell freezes over! In a blog I read today that the Software Freedom Law Center, signed an agreement with Microsoft to receive the protocol documentation needed to fully inter-operate with the Microsoft Windows work-group server. This means FOSS projects like Samba will be able to use this information to improve their project.

SMPlayer Qt4 packages!

This evening I saw a blogpost on Profox blog about packages for SMPlayer, which is a nice cross-platform frontend for MPlayer. It seemed nice but was missing the 64 bit versions and since I run Feisty 64 bit i would liked to have some packages for my architecture. He sent me instructions on how to build them myself and I sent him back my 64 bit versions (Immediatly made a build also for Ubuntu gutsy – the beta version of 7.10 )

Since I bought me a Nokia E65 recently and run Ubuntu most of the time, I was looking around to get these 2 to work together, since I found information scattered all over the internet i tried to bundle it a bit at our LUG wiki

Autofs

Categories: Linux, Software

Since most of my music and video’s reside on my fileserver at home I immediately played them from there under Windows. Now under Ubuntu I found it an annoyance that I each time had to mount my fileserver manually under the local filesystem to be able to play music directly from there. This is where autofs can help out!
You just install the autofs package, remove under /etc/auto.master the comment in front of the line:
/smb /etc/auto.smb
Now you can just browse in a file browser to /smb/fileserver and it will automatically mount smb://fileserver in the folder /smb
(and if it is no longer used also unmount it automatically)
A big thank you to “Wdh” from the Ubuntu-nl irc channel for the tip!
