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?

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!

First we tried to tweak the trac installation, which caused the heavy load, when running the spiders trough. But it turned out, that this doesn’t has the effect to recover the situation, since the trac tree is growing (with the svn tree and revisions). So the spiders have more to crawle and taking more resources away.

We checked our relations and we where lucky to find with waaf.net a sponsor for new server hardware.

Some features of our new ProLiant DL360 server we baptized ‘baikonur‘:

* Dual Core Processor
* 2 GB RAM
* Compaq Smart Array Raid Controller
* 2x 72.8 GB IBM Ultra3 10K
* 2x Gigabit Ethernet
* Integrated Lights Out

The migration was quite relaxed. svn.kvirc.de is a virtual maschine, so we did setup the new host and proudly racked it up at the bandnew hosting center of TMT Teleservice as first (sponsored) customer. The last step was to migrate the system over to the new host and change the DNS records. The outage was something about 5-10 minutes basically caused by the TTL of 600.

Looking into the Load Average I think we have enought resources for a couple of more svn revisions and search engine spiders.

That’s all, happy ircing, and happy developing.

Our favorite distribution released a new major version.
Like every time … it’s the best distribution our project released so far. Many thanks to all those people who did make that happen. If you not married today, maybe you have the possibility to dedicate Lenny to your valentine. :)

It is a (local) security bugfix (and some minor fixes) which was reported on Sunday by Chris Howells to the Debian Security Team (as well as to other vendors). Today DSA-1531 was released.

Right from the DSA:
“… created its socket in an insecure way, which may be exploited to overwrite or remove arbitary files from the local system.”

So please update you systems if you use this package asap.

While we are at policyd-weight… there is one bug open (#471645) where I’m unsure if I want to fix it, cause only stable is effected and the problem can be solved by providing a adjusted array of rbl in the config file. Should I ask for inclusion directly into stable? But it’s a really minor issue. Or try to get 0.1.14.15 uploaded to volatile? I’m really unsure and suggestions are welcome.

After the announcement of Dann Frazier to upload NMU to fix a trivial bug, I thought it’s time again to give some extra care to the package. So I prepared 1.4.11-2 fixing the important bugs and uploaded it. I also commited some minor fixes to the svn, so these issues will get fixed by the next upload.

Since the development of policyd-weigh stalled and unfortunately maybe get stuck, I was looking for an alternative, which maybe found with postfwd. It’s quite flexible but it also will take more time (and care!) to get a reliable configuration, which maybe effective as policyd-weight (still) is right now. While checking the dependencies for postfwd I noticed that Net::DNS::Async isn’t available in Debian (yet). So I decided to create a package starting with dh-make-perl, join the Debian Perl Group and let it review. Damyan Ivanov was so kind to review and upload it, Gregor Herrmann did also give some much useful hints. Thanks to both!

And yes, I also found time to step forward with NM, since I was overloaded the last weeks with usual work and life. Thank to my AM to be so appreciative.

IMHO it’s based on the good balance of community and a small amount of business booth and of course the visitors.
This year we was apart the Sidux Project. Didn’t heared about (much) before, but their slogan is Hot & Spicy! Maybe ‘hot’, cause it’s based on Debian unstable. Hopefully you won’t get tears if it’s too spicy. Anyways … if you want, you could take a look. My opinion is, this would be a good case for a Custom Debian Distribution, if there would be a requirement for it. But he.. everybody is free to do, what ever he want, if nobody else is restricted.
The talks I attended was in most cases excellent, some of them was funny … only one of them did really suck. Desktop Virtualision … after the talk, my question if there could anything else virtualized then the OS from Redmond, was answered with ‘Unfortunetly only XP’ … how lovely!

First we tried Vyatta, but the routing software frequently crashed completly. Maybe this is fixed with VC4 Alpha 1, but we didn’t test that.
Next try was the development version (0.99.9) of quagga from Debian testing, but it looks like a peering with one of our cisco router fails after the hold timer expires.

Now the bad thing: I updated wordpress to 2.3.

With 2.3 there where many infrastructure changes. For a complete list, see the Release Announcement. The most extensions breaking change was the implementation of native tag support. Referencing to Not working Plugin List Ultimate Tag Warrior and Extended Live Archives are problematic. Both caused troubles on update, but there is a fix for ELA and one for UTW. By reviewing the informations for writing this articel, I noticed that I’m running fine with the Ultimate Tag Warrior Bugfix Release provided by Christine from the Internet.
My theme K2 was needing also an update, which caused the style to be broken. So waiting for a fix did take little longer, but when reviewing it, I noticed that only a css class name did need an update.
This all teaches me, when using a project with much depencies, it will be a mess when updating, as long as isn’t all provided by one source. It’s some kind of using a project “still in development”.
Update: While we are at “still in development” .. I updated to 2.3.1-RC1 some seconds ago. :)

]]> http://blog.waja.info/2007/10/27/software-depencies/feed/ 0 http://creativecommons.org/licenses/by-nc-sa/3.0/ wordpress plugin and widget packages http://blog.waja.info/2007/10/20/wordpress-plugin-and-widget-packages/ http://blog.waja.info/2007/10/20/wordpress-plugin-and-widget-packages/#comments Sat, 20 Oct 2007 20:47:38 +0000 cyco http://blog.waja.info/2007/10/20/wordpress-plugin-and-widget-packages/ Yesterday I was going through the plugins and widgets, if there are any updates or such. I realized again, that updating of plugins (and maybe searching for the relocated download source) makes me mad. Also testing and switching back is annoying much.
So I decided to package plugins and widgets I use. Since some plugins and widgets are not maintained long enought for any debian release cycle or getting obsolet with new wordpress releases, I decided to maintain the packages outside of the debian project. Anyways … some people are also scared about the security situation of wordpress. I guess this isn’t much better for wordpress extensions.

Next pity, some extensions or any equivalents aren’t available for wordpress 2.3 (yet). If you run multiple blogs via the stock debian package and wan’t to make use of the new wordpress version in any of your sites, you have update all at once … which maybe not a way you want to go. I decided to repackage wordpress 2.3.0 as wordpress23, which allows you to install wordpress (<<2.3.0) and wordpress23 at same time.

If you want to use debian plugin, widget or theme packages or use these from your normal wordpress installation (/usr/share/wordpress) with wordpress23, you need to symlink the dirs.

For example:

# mv /usr/share/wordpress23/wp-content/plugins/ /usr/share/wordpress23/wp-content/plugins.orig
# mv /usr/share/wordpress23/wp-content/themes/ /usr/share/wordpress23/wp-content/themes.orig
# ln -s /usr/share/wordpress23/wp-content/plugins /usr/share/wordpress/wp-content/plugins
# ln -s /usr/share/wordpress23/wp-content/themes /usr/share/wordpress/wp-content/themes

Remember that package updates of wordpress or wordpress23 may overwrite parts of /usr/share/wordpress/wp-content/[plugins|themes] in such situation. BE CAREFULL!

You can get the stuff via apt-line:

deb ftp://ftp.cyconet.org/debian wordpress main non-free contrib

Or directly from: http://ftp.cyconet.org/debian/archive/wordpress/

The actual package list is:

wordpress-plugin-af-extended-live-archive
wordpress-plugin-ald-spa
wordpress-plugin-all-in-one-seo-pack
wordpress-plugin-exec-php
wordpress-plugin-google-sitemap-generator
wordpress-plugin-landingsites
wordpress-plugin-lightbox-2
wordpress-plugin-now-reading
wordpress-plugin-page-links-to
wordpress-plugin-photopress
wordpress-plugin-related-posts
wordpress-plugin-rolemanager
wordpress-plugin-sideblog
wordpress-plugin-spam-karma
wordpress-plugin-stats
wordpress-plugin-ubernyms
wordpress-plugin-utw
wordpress-plugin-utwgooglesitemaps
wordpress-plugins
wordpress-widget-category-cloud
wordpress-widget-samsarin-php
wordpress-widget-utw-cloud
wordpress-widgets
wordpress23

If you want a plugin or widget included and it makes sence to do so, drop me a mail, where to grab. Be aware that UTW isn’t supported since wordpress 2.3 anymore. A tag system was included into wordpress and you need to search replacements for all the nice UTW extension!

Stay tuned!
