Raspbian Stretch Lite Secure Baseline Setup

The purpose of this tutorial is to walk you through the process of making an installation of Raspbian Stretch Lite more secure. Which you can then create your own image from to use as a baseline setup for future Raspberry Pi projects.

This tutorial assumes that you already know how to flash a microSD card with Raspbian. It also assumes that you are already somewhat familiar with setting up and using a Raspberry Pi.

The Raspberry Pi

In early 2012 I found an article about the Raspberry Pi. All of my news feeds were filled with buzz about “The $35 Computer.” Ever since then my mind and my project to-do list have been filled with projects that the Raspberry Pi could be used for.

I often bring up the Raspberry Pi in casual conversation. People usually get excited about it and want to know more. They will often ask me questions that I can never adequately answer on the spot. I want to be able to say “I don’t have enough time to do this topic justice right now! However, I have wrote about it extensively on my web site! Please, take a look!” If that is why you are here, I’m glad you could make it! 🙂

After having owned and used many Raspberry Pi (Pi) boards, I want to finally start writing about it. Sharing projects where I have utilized the Pi.

I want this blog post to be used for both newcomers and slightly more technically savvy people who just need some recommendations for what to purchase and links to additional resources to get them started.

Please note that I make no claims of being an expert with the Raspberry Pi, Linux, or computer hardware. I consider myself a fanatic!

Dell PowerEdge 840 Upgrade

In January 2012 I purchased a used Dell PowerEdge 840 (PE840) server. Since then I have been using it as a home file and remote desktop server. My eventual goal when I bought the server was to upgrade the server to its maximum capacity. I wanted to use the server as a file and virtualization server. I knew it would take a while to buy all of the components. I started buying components for the upgrade project in March 2015. It is now November 2016 and I have had all of the parts for a few months now. I finally had some time off from work and performed the upgrade.

Specs before upgrade:

CPU: Intel Xeon 3040 Dual-Core 1.86 GHz
RAM: 2 GB DDR2-667 PC2-5300 ECC RAM
Storage: 1-250 GB HDD and 1-2 TB HDD
Connectivity: 1-Gigabit Ethernet Port

Specs after upgrade:

CPU: Intel Xeon X3230 Quad-Core 2.66 GHz
RAM: 8 GB DDR2-667 PC2-5300 ECC RAM
Storage: 1-60 GB SSD, 1-120 GB SSD and 2-5 TB NAS HDDs
Connectivity: 4-Gigabit Ethernet Ports (1 on motherboard, 3 via add-on cards)

The upgrade was successful. The server is running well. The only major problem that I had is with Windows Server 2016. I was hoping to be able to run Windows Server 2016 Hyper-V. It installed without a problem, but it would not recognize the embedded Broadcom Gigabit NIC. I found drivers for the NIC that were created for Windows 7, but they did not work (it was a long shot, I know). I couldn’t find any newer drivers. However, I was able to utilize the NIC with Windows Server 2012 R2.

I am currently using this machine as a file and Hyper-V server. I have two virtual machines running around the clock. (1) VPN Server (CentOS with OpenVPN) and (2) Windows 7 installation that is being utilized as an iTunes server to feed our Apple TV.

I purchased the upgrade components over the course of a year so I was able to distribute the cost. However, the RAM upgrade alone was close to $90 ($45 for 4 GBs). Recently, I had the thought of buying another PE840 to use for additional virtual machines. I found one for $90 (plus shipping) that has the same specs that mine has AFTER I upgraded it. It would be ridiculous for me to purchase another PE840 for $90 when you can get something much better that doesn’t cost that much more. You can get decent brand new servers in the $200 price range. There are much better/newer used servers to be had on eBay for as little as $100-$150. Some with 32 GBs of RAM or better. If you’re dead set on upgrading your PE840, go for it. You’ll appreciate the performance boost. If you haven’t bought the components, I would investigate buying a newer server.

The only component that I haven’t installed is an adequate GPU. It would really be nice for Hyper-V machines so I can take advantage of RemoteFX. However, I don’t think I want to put anymore money into this machine as I am hoping to retire it or re-purpose it soon. If I were to purchase a GPU for it, it looks like the ZOTAC GeForce GT 710 would be the best option. Currently on NewEgg for a little under $50. It is DirectX 12 capable which would allow you to utilize RemoteFX (which requires DX11).

When I started the process of buying the components to upgrade the PE840 I found the following blog post that was extremely useful. If you’re planning to upgrade a PE840, check it out.

What is the best CPU that a Dell Poweredge 840 can take? A Quad Core Xeon X3230!

Central Oregon Road Trip, Labor Day Weekend 2016

Every year my partner and I try to make it to Bend, Oregon. We fell in love with the town in 2011. We’ve been every year since (except for 2014).

The town has a lot of great things to offer. There are great restaurants. One of our favorites is Deschutes Brewery’s Public House. I don’t drink but they have really good food. Now that I am going through this lifestyle change I am thankful they have some great salads on the menu! I really didn’t want to gain the 15 pounds I lost last month back because of poor meal choices on vacation!

In addition to great restaurants, Bend is a great launching point for sightseeing. Crater Lake National Park is just a couple of hours away. When we go to Bend, we always go to Crater Lake! It is one of my favorite places on Earth. There is something about the crisp air and the gorgeous blue water that calls us to come back every year. It doesn’t hurt that Crater Lake Lodge has great food! We’ve only ever been there when they are serving lunch, unfortunately. Hopefully, one of these days, we’ll be able to stay at the lodge and have breakfast and dinner. I also am dying to be at Crater Lake during sunrise, golden hour and sunset!

Crater Lake was PACKED this year. The fact that it was the day before Labor Day did not help! It took forever to even get turned off of the main highway onto the entrance road. It took us over an hour to get up to the entrance pay station. Thankfully, once past the pay station traffic wasn’t too bad. Many of the viewpoints were super crowded though. Thankfully, we have stopped at all of them on our many trips so we just went on to the next one when one was too crowded.

The past few trips that we have made to Bend we have taken a route that allows us to stop by The Painted Hills near John Day, Oregon. The two times we have stopped at The Painted Hills it was raining. This time we were greeted with gorgeous blue skies. To tell you the truth though, I kind of like my pictures of The Painted Hills from our last trip better than the ones I took this time. I may grow to like the ones I took on this trip in the future. I am very critical of my own work and tend to hate it for a while. Most likely because I spend a lot of time fussing over them before I publish them. At a certain point I become sick of them! It could also be because I worked harder on the photos I took the last time. Even though it was cold and raining, I stood out there with the camera on the tripod and even used a light meter. This time it was freestyle shooting all the way.

Because we have made a trip to Crater Lake and The Painted Hills before, I decided to try something different this year. I decided to try my best to take more photos of the details. To do this, I opted to use my telephoto lens instead of my wide angle lens.

The next time we are in Bend, I want to spend more time taking photos of the actual town. More so than I have in the past. It’s a beautiful town. Not too big. Not too small.

If you’re interested, I created an album on Flickr for ALL of the pictures I have taken at Crater Lake. I decided to create this album so I don’t have to send people multiple links to see all of my Crater Lake photos!

Right now I am in a “I hate these photos!” mood, but I hope they’re decent enough for you to enjoy!

Shadow in a Hat

Shadow in a Hat

I do like to pretend that I am abstract artist. I love to put pen and paper together and just see what happens. Last night while I was doing this I looked at the piece and didn’t see anything. I rotated it 90 degrees and saw a hat. I then thought it would look fantastic on our cat Shadow. After digging through the thousands of pictures that I have taken of this cat I found one where he was looking straight at me.

I think the colors of the hat in the original are much better. I haven’t quite figured out how to get scanned ink drawings to look great. Regardless, I think the final piece is fun. Maybe even wall worthy?

Delete OneNote 2016 Templates

The option to delete templates in OneNote 2016 is grayed out. I found a quick solution on the Microsoft Answers site. Copying solution here in case that page ever goes away:

  • Go to C:\Users\yourusername\AppData\Roaming\Microsoft\Templates
  • Open My Templates.one
    • You may be prompted to choose which program to open the file with. Choose OneNote 2016.
  • Your templates will appear as pages. Delete the templates that you don’t need. The template will be removed from the “My Templates” section of OneNote.
    • This does not remove the template from the “Page Templates” button in the ribbon. The old template will go away once you start to use other templates.

Since your templates now appear as an open notebook in OneNote, you can easily switch to it to delete, edit or create new templates.
