Increase the Docker image size for UNRAID

Shortly after LEGO released a $349, 3,599-piece scale model of the Chiron LEGO has upped their game with a fully life sized and drivable model created out of Lego Technic pieces.

The Chiron uses 339 different Technic elements, many of which are used as load-bearing components. It even has working headlights—featuring the first use of some new types of transparent Techic bricks. The car weighs 3,306lbs (1,500kg), and even the powertrain is made from Lego: 2,304 of the little electric motors to be precise.

This seems like an insanely complex undertaking and I am trilled that the folks over at LEGO were able to pull this off!  If you were wondering if the LEGO  model was able to reach the speeds of the actual Chiron I’m sorry to say that it cannot. 🙁

This gives the Chiron somewhat reduced performance compared to the ones Bugatti makes in Molsheim, France. One of those has 1,500hp (1119kW) and a top speed in excess of 261mph (420km/h); the LEGO Technic Bugatti makes just 5.3hp (3.9kW) and tops out at 12.4mph (20km/h).

In my day job I recently came across a much easier was to deal with file and/or directory permissions on Linux based systems. Typically, to determine the permissions of a file or directory you would use the ls command with various potions appended to the end of the command and to change the same file or directory’s permissions you would use the chmod command. As I recently discovered the chmod is also able to clone or copy permissions as well as manually set them.

To lustrate what I ma talking about let’s create a hypothetically example where we have two files with the following permissions.

$ ls -l file*
-rwxr-xr--. 1 lrendek lrendek 0 Apr  7 14:39 file1
-rw-rw-r--. 1 lrendek lrendek 0 Apr  7 14:40 file2

If we wanted to copy the permissions from file 1 onto file2 we would run the following option appended to the chmod command.

$ chmod --reference=file1 file2

As we can see the permissions for file2 have been cloned from file1.

$ ls -l file*
-rwxr-xr--. 1 lrendek lrendek 0 Apr  7 14:39 file1
-rwxr-xr--. 1 lrendek lrendek 0 Apr  7 14:40 file2

If we extend this example further we can also clone the permissions of a directory as well!

$ ls -ld dir*
d--x--x--x. 2 lrendek lrendek 40 Apr  7 14:52 dir1
drwxrwxr-x. 2 lrendek lrendek 40 Apr  7 14:52 dir2
$ chmod --reference=dir1 dir2
$ ls -ld dir*
d--x--x--x. 2 lrendek lrendek 40 Apr  7 14:52 dir1
d--x--x--x. 2 lrendek lrendek 40 Apr  7 14:52 dir2

I had a little bit of an issue finding this but stubbled across this site that provided me with the syntax and examples. Although, I am making this entry mainly for myself but I also hoping that this post will make another Sys. Admin. Job easier. Uf you have any questions, comments, etc. please feel free to contact me on my Contact page or on Twitter.

This is a really weird edge case that I came across at work. After an update to Windows subsystem for Linux (WSL) I was no longer able to use my Cisco AnyConnect VPN connection to connect to any of the infrastructure I manage.

WSL (112) ERROR: CreateProcessParseCommon:782: Failed to translate

Currently, the only method that I have to use a WSL Virtual Machine (VM) is to use this great third party script so that my VM knows how to actually use a network. I do with Microsoft had an easier way to do this, WSL has no network connectivity once connected to a VPN. 🤦🏻‍♂️

At any rate, all of these weird tech issues aside with how I choose to SSH into the systems I manage at work, this is how you correct the error WSL (112) ERROR: CreateProcessParseCommon:782: Failed to translate when attempting to use a WSL VM on a VPN Connection. You will need to edit the .profile folder in your home directory (/home/your_userneame_here) and add the following line to the end of the file.

wsl.exe -d wsl-vpnkit --cd /app service wsl-vpnkit start

To apply the fix, power cycle your WSL VM with your method of choice. I hope this helps and same you time having to search all over the Internet or watch a Youtube “tutorial” what wastes your time. If you have any questions, etc. hit me up via one of the methods on my contact page. Thanks for stopping by! 🙂

This month my home experienced a rare power outage.  It did not last very long but somehow during the outage my trusty ASUS router was powering up but it was not passing any traffic.  I tried various troubleshooting methods but nothing resurrected it.  So, now I am forced to use the WiFi function of my DSL Gateway.  This system is really great for range but terrible for speed and reliability,  My household suffers through this for a few days before we decided that now we are in the market for a new router so after doing some research at The Wirecutter to see what they recommend as they have a really good testing methodologies.

 

The clear winner was of course the Eero Mesh WiFi System.  So my Wife and I made a trip to our local Best Buy to pick up the system that works best for the layout of our ranch style home.  Before installing the new system I ran a few speed tests from my office on a desktop and in carious places through the house on my smart phone.  The results are as follows.

Speed tests from DSL Gateway.

As you can see the signal strength is good but the speeds are terrible.  We were fin unless someone wanted to stream a video and we were buffering very often.

The setup process.

Setting up the Eero Gateway was very easy.  Unbox the gatewayy, install the eero application from your mobile app store of choice, and follow the prompts.

For my home I have the following setup.

• 1x Eero Gateway in the Living Room
  • 1x Belkin undamaged switch
• 1x Eero Beacon in the Kitchen
• 1x Eero Beacon in the Master Bedroom

Once everything synced up and the app advised me everything was connected it did a quick firmware update and restarted all 3 devices.  Once they were all showing back online I ran the same speed tests again.

I find the results pretty compelling and my household is much happier now.  This is not the cheapest router out there but it is a huge improvement  over anything I have used in a long time.  Additionally, this router will never need me to manually upload to

Neofetch is really neat open source tool for displaying your system information on your command line oof choice. There are a lot of instructions on the Internet explaining how to do this on most Linux based system. There is a lot less information for Unix like systems such as macOS. Currently, I am running macOS Montery and as this version of the operating system now uses ZSH over the traditional Bash shell for the Terminal app . Eventually, I figured out that this difference in default shells is why I could not get this to work. If you want to do this for yourself you will need to first install the application.

Now, unlike installing most applications on macOS there is no graphical installer so instead we have to use the fantastic macOS package manager Homebrew. in order to do this open up Terminal and run this command:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Once this is complete and you run this command:

brew install neofetch

Once neoffetch has been installed running it is super easy, just do:

neofetch

Great, now that we have neofetch installed, if you want to run this. every time a Terminal window opens we need to create a .zshrc file in your home directory which will run the neofetch command every time you open a new Terminal window.

 sudo nano .zshrc

then you just add the command into this new blank file

Don’t forget to do ctrl+x to save the file. 🙂

If all went well you should see something similar to this once you quit and open Terminal.
