Adobe Flash 11.2 Background Updates from an Internal Server

One major problem with Adobe Flash Player is that the software often has vulnerability which allow code to take control of a users system. The issue is gets worse by the fact most enterprise environments wont allow their users to have Administrator user rights to reduce the amount of viruses, malware and spyware installed thus not allowing the same users to install the latest version of Adobe Flash Player and leaving them with outdated versions which are vulnerable.

After GOOGLING to try and find a workable restitution I found which talked about a new option in Adobe Flash Player called SilentAutoUpdate. This new option allows System administrators to push settings to Adobe Flash Player by creating a text file called mms.cfg in the users C:\Windows\System32\Macromed\Flash for Windows 32bit or C:\Windows\SysWOW64\Macromed\Flash for Windows 64bit. I’m not going to go into to much detail but I at my work I could use Group Policy to copy this file I’ve created to all my users computer to allow SilentAutoUpdate. SilentAutoUpdate works by a task in the systems Task Scheduler being created and running once a day. This task starts a service called  AdobeFlashPlayerUpdateSvc. The service program is located in the same location as the mms.cfg file called FlashPlayerUpdateService.exe. The FlashPlayerUpdateService.exe reads the mms.cfg file. To enable the SilentAutoUpdate option to log add SilentAutoUpdateVerboseLogging=1 into the mms.cfg file.

The only issue I have with the SilentAutoUpdate option is that the software must have direct access to the internet via ports 443 and 80. In some enterprise environments such as mine must access the internet via a proxy which causes the SilentAutoUpdate to fail to update.

1 way around the SilentAutoUpdate not working via a web proxy is to create an internal mirror. This can be done by following the instructions on the pages 17-19. Once creating a local mirror you can add the option to your mms.cfg file which tells your FlashPlayerUpdateService access the update files via your web server rather than the internet directly.

My MMS.CFG file for testing looks like this but once working I would remove the VerboseLoging option to reduce the log file size. The settings below turn off gui updates and enable silent updates:


Then my other issue was how to I keep my mirror synced with Adobes so I created a Shell Script to do it for me in a daily cron job. The script creates the folder structure, uses wget to download the files and logs everything it does. Save the text below as and ensure the paths are correct before running. To run the script run the command sudo sh ./ once you know to the script is working for you add it to cron.

########## END OF SCRIPT ##########

I have been testing the script and am pleased to see it works well. The log file that the script creates looks much like the flashinstall.log for ease of reading.

Repco has decided to no longer stock Motul oil

A few weeks ago I went into my local Repco store in Albury to find they had moved all the Motul oil from the shelf. I asked a staff member at the enquires counter where the oil was moved to and he informed me that Motul was no longer going to be stocked at Repco and they had moved there existing stock behind the counter.

I went into the store yesterday and to find that all the Motul oils are on the sales table with 10% off. Not exactly a good deal because Repco give customers 10% already by providing a valid NTMA, RACQ or RACV card.

I think that Repco dropping the Motul range is a big blow to car lovers who use this oil like myself. From now on I might be forced into ordering my oil (Motul X-cess 5w40) in 20/25L drums to use in my Subaru WRX 2008.
