Plex Database Cache Setting

The comands below are for Plex in Docker, however you can change the paths relevant to any Plex install.

To get current cache size…

sqlite3 "/opt/appdata/plex/database/Library/Application Support/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db" "PRAGMA default_cache_size;"

Change cache size (and confirm value)

sqlite3 "/opt/appdata/plex/database/Library/Application Support/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db" "PRAGMA default_cache_size = 6000000;" "PRAGMA default_cache_size;"

The default cache size is 20000, if you have thousands of movies and tv shows set it to a larger value (I changed it to 6000000, but any number will work for you)

Before making changes to the sqllite database stop the plex server and service then edit and restart.

also change the paths to your plex installation paths as mine are custom.

Enable Photo Viewer on Windows Server 2016 or 2019

How to Enable Photo Viewer in Windows Server 2019

By default, Photo Viewer isn’t installed or active. The first thing we need to do is check whether or not the DLL’s exist on the server.

Step 1: Check if Photo Viewer DLL’s Exist

Browse to C:\Program Files (x86)\Windows Photo Viewer on the server. If you see .dll files there, that means the files exist but aren’t registered. It should look like this:

If you don’t see those files, simply browse to the path above from a Windows 10 PC & copy the folder contents to the same path on your server.

Step 2: Register the DLL’s

Now that we know the necessary files are present, we need to register them.

Open Command Prompt (type CMD into Start) and right-click to Run as Administrator. Then copy and paste the following code:

regsvr32 “C:\Program Files (x86)\Windows Photo Viewer\PhotoViewer.dll”

Step 3: Download PhotoViewer Registry Keys

Now that the .dll’s are registered, we need to import the registry keys. This allows us to “Open With…” from File Explorer and choose Windows Photo Viewer, as well as set default file associations for various file types, such as .jpg, .jpe, or .jpeg.

Download registry files from here: MS Photoviewer Registry

Once downloaded, right-click the .zip file and extract it to a temporary location.

Step 4: Import Registry Keys

From Start, open Regedit.

File > Import > browse to the location you extracted the 4 registry files. You will need to import all 4 of them.

You should now be able to right-click an image file and Open With Windows Photo Viewer!

Step 5: Set Photo Viewer as Default App

If you’d like to make Photo Viewer your default photo viewing application, search Windows for “Default Apps” and then change Photos to Windows Photo Viewer.

Step 6: Allow Images in Thumbnails

This step is optional, but if you’d like to see a preview of the images from File Explorer (instead of just icons), you can do that by changing the File Explorer options.

Search Windows for Folder Options. Change to the View tab and uncheck “Always show icons, never thumbnails”.

That will change it from looking like this:

to looking like this:

That’s all there is to it! Hopefully this guide helped you out.

How to fix a WordPress HTTPS redirect loop with an NGINX reverse proxy

If your WordPress site is set up to use HTTPS and a reverse proxy, such as an NGINX reverse proxy, is put in front of it you may wind up with an infinite redirect loop.

Following the redirect in dev tools, it looks like this is happening: ->

A head scratcher for sure, but understanding what is going on behind the scenes reveals the issue and the solution together.

Here is what is actually happening:

  • Request is made to
  • The reverse proxy catches the request and makes it’s own request to Take special note that the schema changed to http.
  • The WordPress site sees a request for and says, “Hey, that’s not right, I am at” and tells the browser to go there
  • Repeat indefinitely

You could change the site to support http to the exclusion of https, however that is hacky and anything wanting https will still work itself into an infinite redirect.

An easier solution is to trick WordPress into thinking the request is https enabled.

WordPress looks at a server variable when determining the status of https. Open your wp-config.php file and add the following just after the <?php tag:

if ( $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https' ) {
    $_SERVER['HTTPS'] = 'on';
    $_SERVER['SERVER_PORT'] = 443;

And now your site will work as originally anticipated.

Dastardly isn’t it 😉

Invalid JSON response nginx docker

I’ve recently gotten pihole setup in a docker and use nginx to access it via “dockerhostip/pihole” and all is /was working well.

Today I decided to start playing with internal domain names for my lan so I added one to reference the docker host via the “Local DNS records” section. After testing that worked I went back to the admin page to add some more local domains, however I have discovered when ever I go to the “Local DNS records” page while accessing via domain name I get:

DataTables warning: table id=customDNSTable - Invalid JSON response. For more information about this error, please see

but if I revert back to accessing via IP it works fine.

The reason for this behaviour is because The web interface is only available when accessed by the hostname, pi.hole, or the IP address set in /etc/pihole/setupVars.conf.

You can set your hostname to pihole.home if you’d like.

You could also add it as another valid domain by following these instructions:

Add this to /etc/lighttpd/external.conf (or create it if it doesn’t exist):

setenv.add-environment = ( "VIRTUAL_HOST" => "pihole.home" )

Then restart lighttpd: sudo service lighttpd restart

Automatically purge orphaned objects in Docker

Sometimes your Docker host will fill up with orphaned volumes, containers, images and netowrks.  You can use this image to automatically trim your orphaned volumes every 24 hours:

sudo docker run -d \
--name=docker-prune \
-v /var/run/docker.sock:/var/run/docker.sock \
-e INTERVAL=86400 \
-e "OBJECTS=container volume image network" \
-e "OPTIONS=--filter until=24h" \

Raspberry Pi as Dashboard Controller

Raspberry Pi is a useful embedded computer that can be used for many things including powering informational dashboards.  There are several ways to achieve this with varying complexity however In this tutorial, we will show how to utilise a Raspberry Pi as a Dashboard Controller in a simple straight forward manner.  We are using a Pi 4 revision B however the below has been tested on Pi 3b revisions.

The Pi needs to be configured properly in order to satisfy the following needs:

  • The screen should be fully filled with the view
  • After booting, the predefined screen should be loaded automatically
  • The screen should not sleep after some period of time
  • The mouse cursor should not be visible in the screen
  • Menus and the taskbar should not be visible
  • After an unclean reboot (i.e. after power outage), there should be no browser warning about the unclean shutdown
  • It should be possible to connect to the device remotely to reload or change the view

What you need

  • RaspberryPi
  • 8GB microSD card (preferably with microSD -> SD adapter)
  • (preferably) RaspberryPi case
  • DC charger with 5V output of 2 Amperes and with USB C jack (very common nowadays, as it is used for charging smartphones and tablets).
  • USB keyboard for configuration. A mouse is not necessary

Step 1 – Update your Raspberry Pi

Once you have setup the Raspberry Pi  and are presented with a desktop screen we need to update the device  The following commands are to be run in a Terminal:

sudo apt-get update && sudo apt-get upgrade -y && sudo reboot

Its also a good idea to update the firmware on your Pi:

sudo rpi-update

Once the firmware is updated reboot the device for the next step.

Step 2 – Disable screen timeout

To prevent the screen going blank you need to disable screen timeout.  In the latest versions of RaspbianOS, this is now an option that can be set in the GUI.

Click Start>Preferences>Raspberry Pi Configuration and select the Display tab:

From here, disable Screen Blanking and click ok.  now reboot your Pi again.

Step 3 – Install Unclutter

Unclutter is a tool to disable the mouse being viable when there is no input.  Simply install with the following command in Terminal:

sudo apt-get install unclutter

Step 4 – Create Autostart for Chromium Browser with LXDE

Create two files in /home/pi/.config/lxsession/LXDE-pi – autostart and desktop.conf this can either be by using nano or creating via a ssh tool like WinSCP.

Add the below to autostart and save the file.  You can place the URL of your dashboard after the –incognito flag:

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
# @xscreensaver -no-splash

@xset s off
@xset -dpms
@xset s noblank

@chromium-browser --noerrdialogs --kiosk --disable-infobars --incognito http://URL-GOES-HERE

Add the contents of desktop.conf and save the file:


sGtk/FontName=Roboto Light 12






Reboot the Pi and after a few moments the display should now show the URL dashboard you enetered in autostart.

To rotate more than one dashboard page

The easiest way to achieve this is by installing Revolver – Tabs from the chrome webstore. this can be done by closing down the dashboard instance of Chromium by pressing CFRL-F4 then opening the Chromium Browser from START>Internet>Chromium Browser and clicking the link above.

You’ll need to change settigns within Revolver Tabs, notably rotation time in seconds, auto start and optionally reload.  If you have Reload enabled, you can prevent tabs reloading by specifying their URL’s.  Remember to click save.

As we loaded Chromium in Incognito, you need to enable Revolver Tabs for incognito mode is Google chromium extensions settings.

Once setup second and subsequent URLs you have entered in autostart will automatically rotate.  subsequent URLs can be added with a space in between them:

@chromium-browser --noerrdialogs --kiosk --disable-infobars --incognito http://URL-1 http://URL-2 http://url-3

Link Aggregation on Cisco Switch

First, you need to access the console of your Cisco Switch.

In our example, we are going to use an Opensource software named Putty and a computer running Windows.

The Putty software is available on the website.

After finishing the download, run the software and wait for the following screen.

To access the console of a Cisco Switch model 2960 or 3750, you will need to select the Serial Connection category and use the following options:

• Connection type: Serial
• Serial line: COM1
• Speed: 9600

If COM1 does not work you will need to try to use COM2, COM3, COM4 or the next.

Using either the console, telnet or ssh, connect to the command-line of your switch and log in with a user who has administrative privileges.

On the prompt screen, enter the administrative login information.

After a successful login, the console command-line will be displayed.


Use the enable command to enter the privilege mode.

Switch> enable

Use the configure terminal command to enter the configuration mode.

Switch# configure terminal

Create a new vlan, select an identification number and add a brief description.

Switch(config)# vlan 100
Switch(config-vlan)# name Voip Network
Switch(config)# vlan 200
Switch(config-vlan)# name Data Network
Switch(config-vlan)# exit

On the configuration mode, you need to clear all the configuration from the switch port.

Switch(config)# default interface gigabitEthernet 0/21
Switch(config-if)# default interface gigabitEthernet 0/22

On the configuration mode, add the switch ports to a link aggregation group.

Switch(config)# interface gigabitethernet0/21
Switch(config-if)# channel-group 1 mode active
Switch(config)# interface gigabitethernet0/22
Switch(config-if)# channel-group 1 mode active
Switch(config-if)# exit

In our example, the switch ports 21 and 22 were configured as members of the link aggregation group 1.

To configure the link aggregation ports as a Vlan member, you need to use the following commands.

Switch(config)# interface Port-channel 1
Switch(config)# switchport mode access
Switch(config-if)# switchport access vlan 200
Switch(config-if)# exit
Switch(config)# exit

In our example, the Switch port group 1 was configured as a member of VLAN 200.

To configure the link aggregation ports as a Trunk, you need to use the following commands.

Switch(config)# interface Port-channel 1
Switch(config)# switchport mode trunk
Switch(config-if)# switchport trunk native vlan 1
Switch(config-if)# switchport trunk allowed vlan add 1,100,200
Switch(config-if)# exit

In our example, the Switch port group 1 was configured as a trunk.

The trunk configuration allows the communications of Vlans 1, 100 and 200.

Don’t forget to save your switch configuration.

Switch# copy running-config startup-config

You have successfully configured a link aggregation on a Cisco switch 🙂
