DSM 3 to DSM 4 and DNLA

Posted on April 30, 2012 by metabaron

I recently updated my Synology from DSM 3 to the latest version of DMS 4 (my previous article here) and I’m pleased about the performance boost and the new interface.

But, Friday, when I tried to start a video for my daughter using the DNLA capabilities of my TV, it was unable to find the Synology DNLA server on my network (the DNLA server is named Media Server on Synology DSM 4). As I thought it my be a problem with my TV, I used my iPad, launch AirAv as I previously configured it to connect through my Synology NAS through DNLA/UPnp and same problem.

After being sure that Media Server was up and running (accordingly to DMS 4 control panel), I fired my ssh client and started digging around. Everything seems ok even if I’m currently in talk with Synology tech guys about two or three things I noticed in their scripts and I cannot really find the reason of the DNLA/UPnP Media Server invisible from my iPad and my TV.

At the end, I went one level up and decided to look at the firewall rules, just in case they where changed by the upgrade script and bingo! The rule for DNLA/UPnP was not checked anymore (honestly, I never checked if it was here or not before but I never had a problem with DNLA/UPnP Media Server before!.

So, if you upgrade from DSM 3 to DSM 4 and lost access to your Media Server, check your firewall rules.

From Synology DSM 3 to DSM 4

Posted on April 27, 2012 by metabaron

Few month ago, I bought a Synology NAS in order to save my photos and videos (you have  a lot of theses once you have a kid). And, as I like watching TV series and the choice here in Singapore is not nice, I decided to subscribe to a newsgroup server (Giganews) and I installed SABnzbd + SickBeard + CouchPotato and Headphones on my Synology NAS.

This was all under DSM 3.x, the Linux operating system from Synology. When they updated to the new version (DSM 4.x), I tried to find information about what will happen with my installation of SABnzbd and others if I upgrade. As I was unable to find an answer on Internet or on Synology’s forums and wiki, I did the experiment myself.

Conclusion: if you stored SABnzbd and other on your RAID array (named something like “/volume1″), once the new DSM version installed, you’ll only have to reinstall ipkg and Python (+modules of course).

WordPress automatic plugin update with Debian package

Posted on April 25, 2012 by metabaron

If you installed WordPress using packages, you would certainly would like to be able to use the automatic plugin update feature from the latest versions of WordPress.

Per default, the update system will ask you to run the upgrade through FTP but, with the two following lines (run it as root), WordPress will automatically download and install the updates.

sudo chown www-data wp-admin/plugin-install.php
sudo chown www-data wp-admin/update.php
