IT thoughts and a few bits of randomness

Catching a Thief

My Dad has an old farm shop that is now used irregularly by a relative who now farms in the area. Recently thieves have been boldly driving trucks in and stealing valuable old scrap metal that has accumulated on the property over the years. While the theft of my father's property is a large concern, the fact that they've begun to take bits of farm machines that belong to the relative who now uses the old shop is a greater concern. Wanting to help my dad and the distant cousin, I thought I would put my hacking skills to use and see if we could capture some footage of the wise guys in the act.

So here's the plan. I've got a bunch of spare computers floating around, so I'll install some Linux distribution on one and configure Motion to capture images from two old webcams I have on the shelf. I got started the other evening, and configured Linux Mint on an old Dell GX250 that my in-law's company was throwing out. I choose the GX250 because it is a small form factor machine, and depending on where I have to tuck it, I may be limited on space. Here's a shot of a new one:

I'm not sure whether there will be a weather proof area for me to mount the webcams, so I've sealed them using a trick a friend showed me. A tumbler glass or glass jar seems to be the perfect container to keep the weather and varmints out. Here's a couple of shots of the Quickcam camera sealed up in their new housings:

[caption id="attachment_171" align="alignnone" width="300" caption="Quickcam in Salsa Jar Side View"][/caption]

As you can see in the pics, I used some real (metallic) duct tape to smooth the edges of the holes I had to cut in the lids to plumb the USB cables through. I used the same tape to seal the holes up once the cables were in place. Here are is a few pics of the newer of the two cameras.

I opted for a spaghetti sauce jar for this camera since it is longer than the Quickcam. With both cameras I used some old plastic packing envelopes to fill in around the camera to keep them held in place. I figured the packing material approach would survive longer than trying to tape them to the inside of the glass jars, we'll see.

For what is worth, Motion does all the heavy lifting concerning the image capturing...I just modified the configs a little so I wouldn't fill the hard drive if a bird flew by. Here are the configs if anyone is interested (press Ctrl-END to skip past these if you could care less): ------------------------------------------------------------------------------------------ Main Montion config file - motion.conf # Rename this distribution example file to motion.conf # # This config file was generated by motion 3.2.12

Finally I needed a script to keep the images manageable, so I slapped together this very robust piece of art and scheduled it in cron:

mkdir /data/images/archive/`date +%Y-%m-%d` mkdir /data/images/archive/`date +%Y-%m-%d`/camera1 mkdir /data/images/archive/`date +%Y-%m-%d`/camera2 mv /data/images/camera1/* /data/images/archive/`date +%Y-%m-%d`/camera1 mv /data/images/camera2/* /data/images/archive/`date +%Y-%m-%d`/camera2

It makes some dated folders and camera subfolders, and then moves the day's shots into the appropriate subfolders.

So that's it, hopefully with this evening's worth of lite duty hackery I'll be able to get the system in place this week and capture something interesting. I'll post anything interesting I capture including all the details I discover about the thieves if I manage to get shots of them.

The coming war on general computation

I'd intended to post this a while back when it came out, but other things got in the way. Regardless, Here is Cory Doctorow on the war on general purpose computing. It is a very well done talk, on a situation that I tend to believe is creeping in on us from all angles. I'd be interested in hearing the thoughts of others out there.

Tribal knowledge, what is it?

It’s things in your head now that you haven’t written down because you are reading this. It is the issue you resolved quickly yesterday that you told yourself, “That’s taken care of, no one will need to do that again”. It is the description that you didn’t enter when you closed the ticket out. It is the resolution decided in a hallway meeting. It is the received email that uses improper nouns referring to that things only you would know about. It is that workaround that was so ingenuously constructed that only the creator knows how it operates. It is also, that clattering noise indicating that something is wrong that only you can recognize because you’ve listened for 4,745 days and never heard it before. It is the patterns of those around you as well as the meanings of those patterns. It is the oops, that could have been prevented if there had just been “prior knowledge”. It is the files that are trashed because they are “no longer needed”. It is the information you wished you had, but can’t read, buy, steal, or quickly glean from those around you. It is the false alarm, that you know is a false alarm and not something to be worried about. It is that port on the panel, that did that weird thing once. It is the meta that is never archived. It is the thing, that without it, will makes you feel like it is your first day. It is why you recreate the wheel. It is the knowledge, that if you had now, would probably keep you from trying to improve things. It is the weight the bears down upon those who haven’t shared their knowledge and cages them in. It is the thought you had last week about the repair that you told so-and-so about that was never confirmed. It is the undocumented day-to-day, and the oil our business machines cannot function without.

How is it all connected?

Thought that this was a timely find since many of us would be seeing less tech savvy family and friends through out the holidays.  It is a short documentary by Ben Mendelsohn as to how the Internet and digital communications converge into many interconnecting hubs around the world.

Powershell Script to List All ActiveSync Devices in Exchange Organization

Here's a powershell script I pieced together to do a dump of all the Exchange Activesync devices in an organization.

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noexit -command ". 'C:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1'; Connect-ExchangeServer -auto; Get-ActiveSyncDevice|Export-Csv -Path $home\Documents\ActiveSync-devices.csv -NoTypeInformation; exit;

The resulting output is a CSV file that you can open in your favorite spreadsheet app.

Windows Updates on 2008 Server Managed By WSUS GPO

I, like many others, have servers and workstations that are configured via GPO to obtain updates from a WSUS server. Our servers are managed by an update GPO that allows the appropriate admins greater flexibility to install WSUS provisioned updates (than say the restrictions of the workstation GPO). This is done to allow admins to quickly bring a server up to spec without having to wait for the GPO scheduled install time. In 2003 this worked well because the update notifier on the server would provide notification of updates and the ability to install those updates (typically disabled on a workstation update GPO).

On 2008 the notifier only informs you that your WSUS server has updates waiting to be applied, and offers no way to install them (unless you wait for the GPO schedule). There are GPO options that can be tweaked to allow the manual installation of updates from the 2008 control panel, but none specifically address the manual "Update and Restart" scenario that most admins would like to perform on new servers.

To address this situation, you can jump to the command line and execute:

wuauclt /UpdateNow

It will install updates provisioned from the WSUS server to the GPO managed 2008 server. The Windows Update notifier will inform you that the updates are installing. Hover over it to see the percent complete or if a restart is required. When it is done, restart the server as usual and you are all set.

HTC Please Fix My Meeting Problems

HTC ticket: 10USD280004784 - Meeting acceptance responses sent from HTC Evo to Exchange 2003 / Outlook 2003 show as being sent from the incorrect user. This occurs when when the user accepts a meeting invite and chooses not to "Edit the response". When a user makes a note within their acceptance response, the acceptance reply appears properly to the meeting creator. The EVO shown in the clip is mine (Brian Fitzhugh). When I accept without a note in the body, my response shows as being from the wrong invitee. When I place a note in the response body, it sees the the response as being from the correct invitee.

Domain Controllers, Virtual Machines, and Time

Some quick notes on creating virtual domain controllers:

Don't P2V domain controllers. Build clean VM's, DC promo them, trasfer roles, and setup GC's as needed.

For none xDC VM's disable the Windows Time service and check the host time sync box in the vm's vmtools.

If snapshots are taken of a DC VM, don't revert back to that snapshot (at least in a production environment)

Don't allow the PDC emulator VM to sync its time to an external time source. It should rely on the vmtools for its time. To do this:

Stop the "Windows Time" service

Drill down to HKLM\System\CurrentControlSet\Services\W32Time\Parameters\ Edit the "Type" string to NoSync

Open VMware tools and check the box for "Time synchronization between the virtual machine and the host operating system"

Start the "Windows Time" service
