We’ve had some issues with admins improperly applying permissions in the past, and in recent times as well. Because of this, we’ve decided that maintaining permissions change logging to determine who it is that’s having issues learning how to apply permissions can get some extra training on how to appropriately set file ACEs. The issue with doing this is that it generates ~40GB of compressed Windows logs daily, or closer to 100GB uncompressed. So, how can we use PowerShell to parse through the binary logs, store the info we need, and then get rid of the relatively gigantic evtx files?

On several occasions NFS has inexplicably stopped working with my ZFS shares under ZFS on Linux on Ubuntu Server 14.04×64. It seemed to happen every reboot, after checking the sharenfs property on each of the ZFS FS’ I found they were set properly, but still clients were getting access denied when trying to mount the share. Other times, even when they were able to re-mount the share they wouldn’t do so unless I manually triggered it.

Trying to install Exchange 2013 Management tools on Windows 8.1 is likely to present some problems by default. Unless you’ve already installed the IIS components required by Exchange you’ll get an extremely unhelpful error message when trying to install, saying that it cannot be installed on a client-based OS.

Our fileserver was running low on space and still growing at about 80GB/month. Rather than throw more storage at it, which would only buy us another few months before we had to do it again, I figured I’d look for something that would archive unused data to secondary storage, without rendering it unreachable.

We’re in the middle of an Exchange 2007 to 2013 On Premise migration, and we haven’t been having the best time. After a major mail crash in 2011, every time we’ve attempted to move off the recovered server, either to Exchange 2010 or to a freshly built Exchange 2007 setup, we’ve encountered major, migration stopping issues.

The news about the MySpace’s launch as the new myspace made me remember that I don’t want to have that information on the internet anymore. So I decided to delete my account. Regretfully, the instructions on how to do this aren’t very easy to find, but it was pretty intuitive.

So to get the recently listened to image on the right bar to not trigger an insecure content warning I’m pulling the image from last.fm via a cronjob running once every 15 minutes (just to be nice and not grab the image too often) to curl the image, and making it serve locally.

I want to have speakers in every room of my house, and I want them to be able to play the same stations, or different ones. Basically I want to have digital FM radio across the whole house, so that as I walk from the living room, to the back yard the music doesn’t skip a beat. This is currently offered by Sonos at a ridiculous price, and was offered until 2012 by Logitech, with Squeezebox at a less ridiculous price. Squeezebox being discontinued, I’m not willing to sink my money or time into that, and Sonos is too expensive.

While working to get rid of all our 2003/2008 DCs to get our AD to a 2012 Native level I came across one 2008 DC that was extremely difficult to rid ourselves of. It was created about a year ago to replace our 2003 FSMO master, and had been running without major issue since then. After building a new 2012 VM, and DCPromo’ing it, I transfered the FSMO roles to a stable server and set out to demote and decommission the 2008 machine. Upon running dcpromo from an admin shell, the system began to detect the ADDS binaries, and failed. The message it failed with was an extremely helpful “Failed to detect if Active Directory Domain Services binaries were installed. The error was: An error with no description has occurred.” Lovely.

I’ve been noticing that periodically my MySQL service will hang and require a restart. It’s easy enough to SSH in and restart it, but I only catch it after the fact. So I wrote this little script which curls my website, sees that it’s down and restarts MySQL and shoots me an email with sSMTP. This only checks for the MySQL service not accepting connections from Apache. If there’s an error with Apache, or it’s not running this won’t do anything.
