This is going to be very short and sweet as it is primarily just a note to self. I stuggled with getting outbound mail delivery working for some time and finally got it all figured out. Using Exim4 for mail sending I did the following:

I had a VM using RAW storage format on a ZFS storage object. I needed to delete the RAW hard drive files but couldn’t find them and the “remove” button was greyed out. One post mentioned using “qm rescan” which then allowed the poster to use the remove button but that didn’t work for me. After some research I found out that virtual drives on ZFS storage aren’t actually files but are “ZVOL”s. After a bit more research I came across the solution below to remove these drives manually.

For this tutorial I will be walking through how to use a tool called Realmd to connect an Ubuntu Server or Ubuntu Desktop system to a Windows Active Directory Domain.
In the past I wrote an article talking about how to use Powerbroker Identity Services to do the same thing, but the scope of the article was limited to the server version of Ubuntu only. Furthermore, it has since been my experience that PBIS is an unreliable solution at best.
Part of the confusion I have had on this issue in the last two years has been in thinking that there are only one or maybe two ways to make an Ubuntu Desktop/Server OS connect to a Microsoft Active Directory domain and they both used the same underlying stuff. In fact there are more like 10 different ways to do it all using a mix and match of different technologies.
Finally, I don’t like proprietary stuff. PBIS, while having a free version, was still proprietary. Today we will be using a suite of tools called SSSD. SSSD was created by Redhat and it’s opensource. Furthermore we will be using RealmD, which is a “wrapper” of sorts for SSSD that makes it easier to setup and configure. That’s the short of it. Let’s get started. (more…)
If you run a custom theme for your Owncloud distribution, one of the things you know is that whenever you run an update of your Owncloud server it will automatically disable your theme as part of the update process. This is to keep things from blowing up in the event you have made a modification to a file that will break the updated version of Owncloud.
Themes can be used for more than just visual changes. For example, if you want to disable the “change password” button for users, this can be done by modifying some PHP files and dropping them in your theme. In my case, I added Piwik tracking code in several of my Owncloud files. I want to keep those modifications but I also want the updated code.
This has historically been a pain point during every Owncloud update. Every time I have run an update it has been a laborious process of comparing my theme files to the new stock files and looking for changes and then merging appropriately. So today, I decided to script part of that comparison process… (more…)
