Finally I took the time to find a descent snipping tool for linux… and I found Shutter. A very nice, quick and clean tool to take screenshots and parts of screenshots. The program offers some extra features, yours to find out.
Off course, this is open source software which on integrates nicely in the Gnome notification area. The software is available in the Ubuntu repositories. 
Parallels implemented an overuse policy since version 9 of its Plesk control panel for Linux. When you upgrade a Linux Plesk server (8.x) to version 9.x, all resellers, clients an domains get the “can’t overuse” policy. So, all objects which exceed a certain value get suspended. This isn’t quite what we/you want. (after the night, your overusing resellers/clients/domains will be suspended!)
So, the solution is quite simple: just set all the objects on “allow overuse”… except that this can’t be done serverwide. If you have 300 domains + 100 clients + 5 resellers, you will have to edit 405 objects manually. 
The solution: you can solve this problem by executing the following scripts on the Linux box from the command line (with root privileges). The script will grant clients or domains the “allow overuse” policy.
# for i in `cat /etc/passwd |grep "/var/www/vhosts" | awk -F":" '{print $1}'`; do echo -n "$i -- "; /usr/local/psa/bin/client_pref --update $i -overuse notify ; echo ""; done
# mysql -u'admin' -p"$(cat /etc/psa/.psa.shadow)" -D'psa' -NBe 'select name from domains order by name' | while read dom; do $(grep '^PRODUCT_ROOT_D' /etc/psa/psa.conf | awk '{print $2}')/bin/domain_pref -u "${dom}" -overuse notify; done
Last week, Microsoft changed its omega.contacts.msn.com certificate. This gives you a login error with an already configured Pidgin IM client. Execute the following steps to fix this error:

While testing KDE4.5, it seemed I couldn’t use Tweetdeck anymore. The problem has something to do with storing passwords securely. Since Adobe AIR is a 32-bit application, it needs the 32-bit version of the KDE wallet client libraries in order to get the AIR ELS working properly. (Similarly on GNOME, the 32bit libraries for GNOME keyring are used.)
You can check if 32bit kdewallet client libraries are installed by testing the dynamic link dependencies of e.g. Adobe AIR’s libaddkey.so:
ldd "/opt/Adobe AIR/Versions/1.0/Resources/libaddkey.so" | grep kwallet
If you get something like “libkwalletclient.so.1 => not found” you will need to install the 32bit library. In Ubuntu 9.10 this library is in the kdelibs4c2a package, but this can be detected automatically by the getlibs package (see http://ubuntuforums.org/showthread.php?t=474790):
wget http://frozenfox.freehostia.com/cappy/getlibs-all.deb sudo dpkg -i getlibs-all.deb sudo getlibs libkwalletclient.so.1 sudo ldconfig
Re-run the ldd command above to check that the client library can now be resolved.
After this, erase Adobe AIR ELS and enter your account data anew:
rm -rf ~/.appdata/Adobe/AIR/ELS TweetDeck
After this, AdobeAIR shows up in KDE wallet manager with an ELSKey stored password.
I found this solution on the Ubuntuforum.org. (provided by mkalen in this topic)
… and finally I found a VPN client that suits my needs: the Shrew Soft VPNClient. This piece of software is available for both Windows and Linux. (and works on both platforms without a problem!) It connects with many manufacturers’ VPN gateways. On their support page, they tell you how to do it.
Attention, there is one little “problem” if you want to use it on recent Ubuntu installations. You have to edit the file “/etc/sysctl.d/10-network-security.conf”. Please zero the values of the configuration:
net.ipv4.conf.default.rp_filter=0
net.ipv4.conf.all.rp_filter=0
That should work.
Laatst was ik op zoek naar goede online backup software zodat ik wat cruciale data kan backuppen. Buiten de commerciële producten, kwam ik toevallig het Ubuntu One project tegen, dat blijkbaar al een tijdje loopt. Deze software zit standaard in de laatste Karmic release van Ubuntu ingebakken, super! Het project lijkt een beetje op het oude Ifolder project van Novell (dat blijkbaar ook terug leeft).
Ubuntu One bestaat enerzijds uit client software die files synchronizeert vanop je computer met “the storage cloud”. Anderzijds is er ook een webinterface die je vanop elke browser-waardige computer kan raadplegen. Ubuntu One bied je gratis online storage aan tot 2GB. Hoger volumes kunnen aangekocht worden tot 100GB. Achterliggend gebruikt Ubuntu One de Amazon S3 cloud voor het opslaan van al zijn data.
Toch zijn er 3 minpuntjes. Momenteel zijn er enkel Linux clients beschikbaar, dus crossplatform werken gaat niet. Blijkbaar bevindt de data zich niet geëncrypteerd op de servers (hoorde ik, correct me if I’m wrong). Ook zet je de Ubuntu One client upload en download speed best niet op 0KB/s, want dan komt er effectief geen data door. Daar waar de meeste applicaties dan unlimited bandbreedte toelaten…
Ik kijk uit naar de nieuwe client versie en nieuwe features in de volgende Ubuntu release!
Recently, I asked myself, what about a new graphics card for my pc? Since it was terribly slow… So I started looking around and bought myself an Asus Nvidia GTS250 card. This was a logic choice because Nvidia has good Linux drivers and this cards aren’t too expensive. But, it turned out that the card makes more noise than a vacuum-cleaner.
I returned the card and went looking for another one. The Sapphire ATI HD5750 Vapor-X 1G GDDR5 seemed to be the perfect quiet replacement. ATI supports Linux with binary drivers, so that was no problem (I tought). After installing the card with the latest proper drivers, all worked well. When suddenly… after 10 minutes my computer (videocard) crashed and my screen showed vertical lines. Most of the time I could SSH to the computer, so it didn’t totaly crash, but I was unable to relaunch Xorg. The graphics card was totally losing control.
After some surfing, emailing and chatting around, it turned out that many people are facing problems (ATI forum thread) with this cards. Finally, a good solution came from Sapphire. I had to upgrade the video bios from the graphics card. The new VBIOS adjust the powerplay function in 2D mode. Underneath you find my solution:
!! IMPORTANT, please check that your card has the following P/N:288-1E138-100SA and SKU#11164-04 !!
!! Don’t turn off the computer and do this at own risk !!
I’m hoping that this solves your problem too!
If you ever want to delete your entire Evolution account, history, configuration, settings, etc and start over from scratch, here’s how to do it:
Back up all of your files first (of course).
$ rm -rf ~/.evolution
$ rm -rf ~/.gconf/apps/evolution
$ evolution --force-shutdown
Find the process id for ‘gconfd’ and kill it:
$ ps -ef | grep gconfd
$ kill <pid>
Restart Evolution and you should be prompted to set up your acccount.

Sometimes, copying big files/volumes with DD takes much time. With this simple script, you ‘ll see the progress of the copying process (in MB). (source)
dd if=/boot.img.gz of=/dev/sda -pg bs=1M 2>&1 | perl -e 'print $i++." MBn" while(read(STDIN,$c,3));'Finally there’s a bugfix for the Linux kernel SATA bug I mentioned in this post. This is how I fixed it on my Ubuntu 7.04 machine:
- Make a file called stopsata in the folder /etc/init.d
The file should contain the following two rules:
#!/bin/sh
echo 1 > /sys/class/scsi_disk/0\:0\:0\:0/stop_on_shutdown
- Make a file called S89stopsata in the folder /etc/rc0.d
The file is a symlink to the previously made script. You can link it with:
ln -s /etc/init.d/stopsata S89stopsata
Attention, Ubuntu 7.04 is using kernel 2.6.20.x. This fix is already included in the kernel but not standard activated yet.
