Red Hat OpenShift Container Platform Instruction Manual for Windows Powershell

Introduction to the manual
This manual is made to guide you step by step in setting up an OpenShift cloud environment on your own device. It will tell you what needs to be done, when it needs to be done, what you will be doing and why you will be doing it, all in one convenient manual that is made for Windows users. Although if you'd want to try it on Linux or MacOS we did add the commands necesary to get the CodeReady Containers to run on your operating system. Be warned however there are some system requirements that are necessary to run the CodeReady Containers that we will be using. These requirements are specified within chapter Minimum system requirements.
This manual is written for everyone with an interest in the Red Hat OpenShift Container Platform and has at least a basic understanding of the command line within PowerShell on Windows. Even though it is possible to use most of the manual for Linux or MacOS we will focus on how to do this within Windows.
If you follow this manual you will be able to do the following items by yourself:
● Installing the CodeReady Containers
● Updating OpenShift
● Configuring a CodeReady Container
● Configuring the DNS
● Accessing the OpenShift cluster
● Deploying the Mediawiki application
What is the OpenShift Container platform?
Red Hat OpenShift is a cloud development Platform as a Service (PaaS). It enables developers to develop and deploy their applications on a cloud infrastructure. It is based on the Kubernetes platform and is widely used by developers and IT operations worldwide. The OpenShift Container platform makes use of CodeReady Containers. CodeReady Containers are pre-configured containers that can be used for developing and testing purposes. There are also CodeReady Workspaces, these workspaces are used to provide any member of the development or IT team with a consistent, secure, and zero-configuration development environment.
The OpenShift Container Platform is widely used because it helps the programmers and developers make their application faster because of CodeReady Containers and CodeReady Workspaces and it also allows them to test their application in the same environment. One of the advantages provided by OpenShift is the efficient container orchestration. This allows for faster container provisioning, deploying and management. It does this by streamlining and automating the automation process.
What knowledge is required or recommended to proceed with the installation?
To be able to follow this manual some knowledge is mandatory, because most of the commands are done within the Command Line interface it is necessary to know how it works and how you can browse through files/folders. If you either don’t have this basic knowledge or have trouble with the basic Command Line Interface commands from PowerShell, then a cheat sheet might offer some help. We recommend the following cheat sheet for windows:
Https://www.sans.org/security-resources/sec560/windows\_command\_line\_sheet\_v1.pdf
Another option is to read through the operating system’s documentation or introduction guides. Though the documentation can be overwhelming by the sheer amount of commands.
Microsoft: https://docs.microsoft.com/en-us/windows-serveadministration/windows-commands/windows-commands
MacOS
Https://www.makeuseof.com/tag/mac-terminal-commands-cheat-sheet/
Linux

http://cc.iiti.ac.in/docs/linuxcommands.pdf
Aside from the required knowledge there are also some things that can be helpful to know just to make the use of OpenShift a bit simpler. This consists of some general knowledge on PaaS like Dockers and Kubernetes.

System requirements

Minimum System requirements

The minimum system requirements for the Red Hat OpenShift CodeReady Containers has the following minimum hardware:
Hardware requirements
Code Ready Containers requires the following system resources:
● 4 virtual CPU’s
● 9 GB of free random-access memory
● 35 GB of storage space
● Physical CPU with Hyper-V (intel) or SVM mode (AMD) this has to be enabled in the bios
Software requirements
The minimum system requirements for the Red Hat OpenShift CodeReady Containers has the following minimum operating system requirements:
Microsoft Windows
On Microsoft Windows, the Red Hat OpenShift CodeReady Containers requires the Windows 10 Pro Fall Creators Update (version 1709) or newer. CodeReady Containers does not work on earlier versions or other editions of Microsoft Windows. Microsoft Windows 10 Home Edition is not supported.
macOS
On macOS, the Red Hat OpenShift CodeReady Containers requires macOS 10.12 Sierra or newer.
Linux
On Linux, the Red Hat OpenShift CodeReady Containers is only supported on Red Hat Enterprise Linux/CentOS 7.5 or newer and on the latest two stable Fedora releases.
When using Red Hat Enterprise Linux, the machine running CodeReady Containers must be registered with the Red Hat Customer Portal.
Ubuntu 18.04 LTS or newer and Debian 10 or newer are not officially supported and may require manual set up of the host machine.

Required additional software packages for Linux

The CodeReady Containers on Linux require the libvirt and Network Manager packages to run. Consult the following table to find the command used to install these packages for your Linux distribution:
Table 1.1 Package installation commands by distribution
Linux Distribution Installation command
Fedora Sudo dnf install NetworkManager
Red Hat Enterprise Linux/CentOS Su -c 'yum install NetworkManager'
Debian/Ubuntu Sudo apt install qemu-kvm libvirt-daemonlibvirt-daemon-system network-manage

Installation

Getting started with the installation

To install CodeReady Containers a few steps must be undertaken. Because an OpenShift account is necessary to use the application this will be the first step. An account can be made on “https://www.openshift.com/”, where you need to press login and after that select the option “Create one now”
After making an account the next step is to download the latest release of CodeReady Containers and the pulled secret on “https://cloud.redhat.com/openshift/install/crc/installer-provisioned”. Make sure to download the version corresponding to your platform and/or operating system. After downloading the right version, the contents have to be extracted from the archive to a location in your $PATH. The pulled secret should be saved because it is needed later.
The command line interface has to be opened before we can continue with the installation. For windows we will use PowerShell. All the commands we use during the installation procedure of this guide are going to be done in this command line interface unless stated otherwise. To be able to run the commands within the command line interface, use the command line interface to go to the location in your $PATH where you extracted the CodeReady zip.
If you have installed an outdated version and you wish to update, then you can delete the existing CodeReady Containers virtual machine with the $crc delete command. After deleting the container, you must replace the old crc binary with a newly downloaded binary of the latest release.
C:\Users\[username]\$PATH>crc delete 
When you have done the previous steps please confirm that the correct and up to date crc binary is in use by checking it with the $crc version command, this should provide you with the version that is currently installed.
C:\Users\[username]\$PATH>crc version 
To set up the host operating system for the CodeReady Containers virtual machine you have to run the $crc setup command. After running crc setup, crc start will create a minimal OpenShift 4 cluster in the folder where the executable is located.
C:\Users\[username]>crc setup 

Setting up CodeReady Containers

Now we need to set up the new CodeReady Containers release with the $crc setup command. This command will perform the operations necessary to run the CodeReady Containers and create the ~/.crc directory if it did not previously exist. In the process you have to supply your pulled secret, once this process is completed you have to reboot your system. When the system has restarted you can start the new CodeReady Containers virtual machine with the $crc start command. The $crc start command starts the CodeReady virtual machine and OpenShift cluster.
You cannot change the configuration of an existing CodeReady Containers virtual machine. So if you have a CodeReady Containers virtual machine and you want to make configuration changes you need to delete the virtual machine with the $crc delete command and create a new virtual machine and start that one with the configuration changes. Take note that deleting the virtual machine will also delete the data stored in the CodeReady Containers. So, to prevent data loss we recommend you save the data you wish to keep. Also keep in mind that it is not necessary to change the default configuration to start OpenShift.
C:\Users\[username]\$PATH>crc setup 
Before starting the machine, you need to keep in mind that it is not possible to make any changes to the virtual machine. For this tutorial however it is not necessary to change the configuration, if you don’t want to make any changes please continue by starting the machine with the crc start command.
C:\Users\[username]\$PATH>crc start 
\ it is possible that you will get a Nameserver error later on, if this is the case please start it with* crc start -n 1.1.1.1

Configuration

It is not is not necessary to change the default configuration and continue with this tutorial, this chapter is here for those that wish to do so and know what they are doing. However, for MacOS and Linux it is necessary to change the dns settings.

Configuring the CodeReady Containers

To start the configuration of the CodeReady Containers use the command crc config. This command allows you to configure the crc binary and the CodeReady virtual machine. The command has some requirements before it’s able to configure. This requirement is a subcommand, the available subcommands for this binary and virtual machine are:
get, this command allows you to see the values of a configurable property
set/unset, this command can be used for 2 things. To display the names of, or to set and/or unset values of several options and parameters. These parameters being:
○ Shell options
○ Shell attributes
○ Positional parameters
view, this command starts the configuration in read-only mode.
These commands need to operate on named configurable properties. To list all the available properties, you can run the command $crc config --help.
Throughout this manual we will use the $crc config command a few times to change some properties needed for the configuration.
There is also the possibility to use the crc config command to configure the behavior of the checks that’s done by the $crc start end $crc setup commands. By default, the startup checks will stop with the process if their conditions are not met. To bypass this potential issue, you can set the value of a property that starts with skip-check or warn-check to true to skip the check or warning instead of ending up with an error.
C:\Users\[username]\$PATH>crc config get C:\Users\[username]\$PATH>crc config set C:\Users\[username]\$PATH>crc config unset C:\Users\[username]\$PATH>crc config view C:\Users\[username]\$PATH>crc config --help 

Configuring the Virtual Machine

You can use the CPUs and memory properties to configure the default number of vCPU’s and amount of memory available for the virtual machine.
To increase the number of vCPU’s available to the virtual machine use the $crc config set CPUs . Keep in mind that the default number for the CPU’s is 4 and the number of vCPU’s you wish to assign must be equal or greater than the default value.
To increase the memory available to the virtual machine, use the $crc config set memory . Keep in mind that the default number for the memory is 9216 Mebibytes and the amount of memory you wish to assign must be equal or greater than the default value.
C:\Users\[username]\$PATH>crc config set CPUs  C:\Users\[username]\$PATH>crc config set memory > 

Configuring the DNS

Window / General DNS setup

There are two domain names used by the OpenShift cluster that are managed by the CodeReady Containers, these are:
crc.testing, this is the domain for the core OpenShift services.
apps-crc.testing, this is the domain used for accessing OpenShift applications that are deployed on the cluster.
Configuring the DNS settings in Windows is done by executing the crc setup. This command automatically adjusts the DNS configuration on the system. When executing crc start additional checks to verify the configuration will be executed.

macOS DNS setup

MacOS expects the following DNS configuration for the CodeReady Containers
● The CodeReady Containers creates a file that instructs the macOS to forward all DNS requests for the testing domain to the CodeReady Containers virtual machine. This file is created at /etc/resolvetesting.
● The oc binary requires the following CodeReady Containers entry to function properly, api.crc.testing adds an entry to /etc/hosts pointing at the VM IPaddress.

Linux DNS setup

CodeReady containers expect a slightly different DNS configuration. CodeReady Container expects the NetworkManager to manage networking. On Linux the NetworkManager uses dnsmasq through a configuration file, namely /etc/NetworkManageconf.d/crc-nm-dnsmasq.conf.
To set it up properly the dnsmasq instance has to forward the requests for crc.testing and apps-crc.testing domains to “192.168.130.11”. In the /etc/NetworkManageconf.d/crc-nm-dnsmasq.conf this will look like the following:
● Server=/crc. Testing/192.168.130.11
● Server=/apps-crc. Testing/192.168.130.11

Accessing the Openshift Cluster

Accessing the Openshift web console

To gain access to the OpenShift cluster running in the CodeReady virtual machine you need to make sure that the virtual machine is running before continuing with this chapter. The OpenShift clusters can be accessed through the OpenShift web console or the client binary(oc).
First you need to execute the $crc console command, this command will open your web browser and direct a tab to the web console. After that, you need to select the htpasswd_provider option in the OpenShift web console and log in as a developer user with the output provided by the crc start command.
It is also possible to view the password for kubeadmin and developer users by running the $crc console --credentials command. While you can access the cluster through the kubeadmin and developer users, it should be noted that the kubeadmin user should only be used for administrative tasks such as user management and the developer user for creating projects or OpenShift applications and the deployment of these applications.
C:\Users\[username]\$PATH>crc console C:\Users\[username]\$PATH>crc console --credentials 

Accessing the OpenShift cluster with oc

To gain access to the OpenShift cluster with the use of the oc command you need to complete several steps.
Step 1.
Execute the $crc oc-env command to print the command needed to add the cached oc binary to your PATH:
C:\Users\[username]\$PATH>crc oc-env 
Step 2.
Execute the printed command. The output will look something like the following:
PS C:\Users\OpenShift> crc oc-env $Env:PATH = "CC:\Users\OpenShift\.crc\bin\oc;$Env:PATH" # Run this command to configure your shell: # & crc oc-env | Invoke-Expression 
This means we have to execute* the command that the output gives us, in this case that is:
C:\Users\[username]\$PATH>crc oc-env | Invoke-Expression 
\this has to be executed every time you start; a solution is to move the oc binary to the same path as the crc binary*
To test if this step went correctly execute the following command, if it returns without errors oc is set up properly
C:\Users\[username]\$PATH>.\oc 
Step 3
Now you need to login as a developer user, this can be done using the following command:
$oc login -u developer https://api.crc.testing:6443
Keep in mind that the $crc start will provide you with the password that is needed to login with the developer user.
C:\Users\[username]\$PATH>oc login -u developer https://api.crc.testing:6443 
Step 4
The oc can now be used to interact with your OpenShift cluster. If you for instance want to verify if the OpenShift cluster Operators are available, you can execute the command
$oc get co 
Keep in mind that by default the CodeReady Containers disables the functions provided by the commands $machine-config and $monitoringOperators.
C:\Users\[username]\$PATH>oc get co 

Demonstration

Now that you are able to access the cluster, we will take you on a tour through some of the possibilities within OpenShift Container Platform.
We will start by creating a project. Within this project we will import an image, and with this image we are going to build an application. After building the application we will explain how upscaling and downscaling can be used within the created application.
As the next step we will show the user how to make changes in the network route. We also show how monitoring can be used within the platform, however within the current version of CodeReady Containers this has been disabled.
Lastly, we will show the user how to use user management within the platform.

Creating a project

To be able to create a project within the console you have to login on the cluster. If you have not yet done this, this can be done by running the command crc console in the command line and logging in with the login data from before.
When you are logged in as admin, switch to Developer. If you're logged in as a developer, you don't have to switch. Switching between users can be done with the dropdown menu top left.
Now that you are properly logged in press the dropdown menu shown in the image below, from there click on create a project.

Importing image

The Containers in OpenShift Container Platform are based on OCI or Docker formatted images. An image is a binary that contains everything needed to run a container as well as the metadata of the requirements needed for the container.
Within the OpenShift Container Platform it’s possible to obtain images in a number of ways. There is an integrated Docker registry that offers the possibility to download new images “on the fly”. In addition, OpenShift Container Platform can use third party registries such as:
- Https://hub.docker.com/
- Https://catalog.redhat.com/software/containers/search
Within this manual we are going to import an image from the Red Hat container catalog. In this example we’ll be using MediaWiki.
Search for the application in https://catalog.redhat.com/software/containers/search

https://preview.redd.it/c4mrbs0fitv51.png?width=672&format=png&auto=webp&s=f708f0542b53a9abf779be2d91d89cf09e9d2895
Navigate to “Get this image”
Follow the steps to “create a registry service account”, after that you can copy the YAML.
https://preview.redd.it/b4rrklqfitv51.png?width=1323&format=png&auto=webp&s=7a2eb14a3a1ba273b166e03e1410f06fd9ee1968
After the YAML has been copied we will go to the topology view and click on the YAML button
https://preview.redd.it/k3qzu8dgitv51.png?width=869&format=png&auto=webp&s=b1fefec67703d0a905b00765f0047fe7c6c0735b
Then we have to paste in the YAML, put in the name, namespace and your pull secret name (which you created through your registry account) and click on create.

Run the import command within powershell
$oc import-image openshift4/mediawiki --from=registry.redhat.io/openshift4/mediawiki --confirm imagestream.image.openshift.io/mediawiki imported 

Creating and managing an application

There are a few ways to create and manage applications. Within this demonstration we’ll show how to create an application from the previously imported image.

Creating the application

To create an image with the previously imported image go back to the console and topology. From here on select container image.
https://preview.redd.it/6506ea4iitv51.png?width=869&format=png&auto=webp&s=c0231d70bb16c76cd131e6b71256e93550cc8b37
For the option image you'll want to select the “image stream tag from internal registry” option. Give the application a name and then create the deployment.
https://preview.redd.it/tk72idniitv51.png?width=813&format=png&auto=webp&s=a4e662cf7b96604d84df9d04ab9b90b5436c803c
If everything went right during the creating process you should see the following, this means that the application is successfully running.

Scaling the application

In OpenShift there is a feature called autoscaling. There are two types of application scaling, namely vertical scaling, and horizontal scaling. Vertical scaling is adding only more CPU and hard disk and is no longer supported by OpenShift. Horizontal scaling is increasing the number of machines.
One of the ways to scale an application is by increasing the number of pods. This can be done by going to a pod within the view as seen in the previous step. By either pressing the up or down arrow more pods of the same application can be added. This is similar to horizontal scaling and can result in better performance when there are a lot of active users at the same time.
https://preview.redd.it/s6i1vbcrltv51.png?width=602&format=png&auto=webp&s=e62cbeeed116ba8c55704d61a990fc0d8f3cfaa1
In the picture above we see the number of nodes and pods and how many resources those nodes and pods are using. This is something to keep in mind if you want to scale up your application, the more you scale it up, the more resources it will take up.

https://preview.redd.it/quh037wmitv51.png?width=194&format=png&auto=webp&s=5e326647b223f3918c259b1602afa1b5fbbeea94

Network

Since OpenShift Container platform is built on Kubernetes it might be interesting to know some theory about its networking. Kubernetes, on which the OpenShift Container platform is built, ensures that the Pods within OpenShift can communicate with each other via the network and assigns them their own IP address. This makes all containers within the Pod behave as if they were on the same host. By giving each pod its own IP address, pods can be treated as physical hosts or virtual machines in terms of port mapping, networking, naming, service discovery, load balancing, application configuration and migration. To run multiple services such as front-end and back-end services, OpenShift Container Platform has a built-in DNS.
One of the changes that can be made to the networking of a Pod is the Route. We’ll show you how this can be done in this demonstration.
The Route is not the only thing that can be changed and or configured. Two other options that might be interesting but will not be demonstrated in this manual are:
- Ingress controller, Within OpenShift it is possible to set your own certificate. A user must have a certificate / key pair in PEM-encoded files, with the certificate signed by a trusted authority.
- Network policies, by default all pods in a project are accessible from other pods and network locations. To isolate one or more pods in a project, it is possible to create Network Policy objects in that project to indicate the allowed incoming connections. Project administrators can create and delete Network Policy objects within their own project.
There is a search function within the Container Platform. We’ll use this to search for the network routes and show how to add a new route.
https://preview.redd.it/8jkyhk8pitv51.png?width=769&format=png&auto=webp&s=9a8762df5bbae3d8a7c92db96b8cb70605a3d6da
You can add items that you use a lot to the navigation
https://preview.redd.it/t32sownqitv51.png?width=1598&format=png&auto=webp&s=6aab6f17bc9f871c591173493722eeae585a9232
For this example, we will add Routes to navigation.
https://preview.redd.it/pm3j7ljritv51.png?width=291&format=png&auto=webp&s=bc6fbda061afdd0780bbc72555d809b84a130b5b
Now that we’ve added Routes to the navigation, we can start the creation of the Route by clicking on “Create route”.

Storage
OpenShift makes use of Persistent Storage, this type of storage uses persistent volume claims(PVC). PVC’s allow the developer to make persistent volumes without needing any knowledge about the underlying infrastructure.
Within this storage there are a few configuration options:
It is however important to know how to manually reclaim the persistent volumes, since if you delete PV the associated data will not be automatically deleted with it and therefore you cannot reassign the storage to another PV yet.
To manually reclaim the PV, you need to follow the following steps:
Step 1: Delete the PV, this can be done by executing the following command
$oc delete  
Step 2: Now you need to clean up the data on the associated storage asset
Step 3: Now you can delete the associated storage asset or if you with to reuse the same storage asset you can now create a PV with the storage asset definition.
It is also possible to directly change the reclaim policy within OpenShift, to do this you would need to follow the following steps:
Step 1: Get a list of the PVs in your cluster
$oc get pv 
This will give you a list of all the PV’s in your cluster and will display their following attributes: Name, Capacity, Accesmodes, Reclaimpolicy, Statusclaim, Storageclass, Reason and Age.
Step 2: Now choose the PV you wish to change and execute one of the following command’s, depending on your preferred policy:
$oc patch pv  -p '{"spec":{"persistentVolumeReclaimPolicy":"Retain"}}' 
In this example the reclaim policy will be changed to Retain.
$oc patch pv  -p '{"spec":{"persistentVolumeReclaimPolicy":"Recycle"}}' 
In this example the reclaim policy will be changed to Recycle.
$oc patch pv  -p '{"spec":{"persistentVolumeReclaimPolicy":"Delete"}}' 
In this example the reclaim policy will be changed to Delete.

Step 3: After this you can check the PV to verify the change by executing this command again:
$oc get pv 

Monitoring

Within Red Hat OpenShift there is the possibility to monitor the data that has been created by your containers, applications, and pods. To do so, click on the menu option in the top left corner. Check if you are logged in as Developer and click on “Monitoring”. Normally this function is not activated within the CodeReady containers, because it uses a lot of resources (Ram and CPU) to run.
https://preview.redd.it/an0wvn6zitv51.png?width=228&format=png&auto=webp&s=51abf8cc31bd763deb457d49514f99ee81d610ec
Once you have activated “Monitoring” you can change the “Time Range” and “Refresh Interval” in the top right corner of your screen. This will change the monitoring data on your screen.
https://preview.redd.it/e0yvzsh1jtv51.png?width=493&format=png&auto=webp&s=b2c563635cfa60ea7ce2f9c146aa994df6aa1c34
Within this function you can also monitor “Events”. These events are records of important information and are useful for monitoring and troubleshooting within the OpenShift Container Platform.
https://preview.redd.it/l90vkmp3jtv51.png?width=602&format=png&auto=webp&s=4e97f14bedaec7ededcdcda96e7823f77ced24c2

User management

According to the documentation of OpenShift is a user, an entity that interacts with the OpenShift Container Platform API. These can be a developer for developing applications or an administrator for managing the cluster. Users can be assigned to groups, which set the permissions applied to all the group’s members. For example, you can give API access to a group, which gives all members of the group API access.
There are multiple ways to create a user depending on the configured identity provider. The DenyAll identity provider is the default within OpenShift Container Platform. This default denies access for all the usernames and passwords.
First, we’re going to create a new user, the way this is done depends on the identity provider, this depends on the mapping method used as part of the identity provider configuration.
for more information on what mapping methods are and how they function:
https://docs.openshift.com/enterprise/3.1/install_config/configuring_authentication.html
With the default mapping method, the steps will be as following
$oc create user  
Next up, we’ll create an OpenShift Container Platform Identity. Use the name of the identity provider and the name that uniquely represents this identity in the scope of the identity provider:
$oc create identity : 
The is the name of the identity provider in the master configuration. For example, the following commands create an Identity with identity provider ldap_provider and the identity provider username mediawiki_s.
$oc create identity ldap_provider:mediawiki_s 
Create a useidentity mapping for the created user and identity:
$oc create useridentitymapping :  
For example, the following command maps the identity to the user:
$oc create useridentitymapping ldap_provider:mediawiki_s mediawiki 
Now were going to assign a role to this new user, this can be done by executing the following command:
$oc create clusterrolebinding  \ --clusterrole= --user= 
There is a --clusterrole option that can be used to give the user a specific role, like a cluster user with admin privileges. The cluster admin has access to all files and is able to manage the access level of other users.
Below is an example of the admin clusterrole command:
$oc create clusterrolebinding registry-controller \ --clusterrole=cluster-admin --user=admin 

What did you achieve?

If you followed all the steps within this manual you now should have a functioning Mediawiki Application running on your own CodeReady Containers. During the installation of this application on CodeReady Containers you have learned how to do the following things:
● Installing the CodeReady Containers
● Updating OpenShift
● Configuring a CodeReady Container
● Configuring the DNS
● Accessing the OpenShift cluster
● Deploying an application
● Creating new users
With these skills you’ll be able to set up your own Container Platform environment and host applications of your choosing.

Troubleshooting

Nameserver
There is the possibility that your CodeReady container can't connect to the internet due to a Nameserver error. When this is encountered a working fix for us was to stop the machine and then start the CRC machine with the following command:

Terms and definitions

These terms and definitions will be expanded upon, below you can see an example of how this is going to look like together with a few terms that will require definitions.
Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. Openshift is based on Kubernetes.
Clusters are a collection of multiple nodes which communicate with each other to perform a set of operations.
Containers are the basic units of OpenShift applications. These container technologies are lightweight mechanisms for isolating running processes so that they are limited to interacting with only their designated resources.
CodeReady Container is a minimal, preconfigured cluster that is used for development and testing purposes.
CodeReady Workspaces uses Kubernetes and containers to provide any member of the development or IT team with a consistent, secure, and zero-configuration development environment.

Non-linear stretch and update on the open-source gyro-assisted video stabilization project

Hey everyone. You might remember this post from around a month ago about developing a program that can use Betaflight blackbox data for stabilizing FPV footage similar to Reelsteady. Here's an update on the project.
TL;DR: Stabilization doesn't work yet but I'm slowly getting there. The code so far can be found on this Github Repo, which currently contains working code for a camera calibration utility and a utility for non-linear stretching (superview-like) of 4:3 video to 16:9. I've made a binary available for download with the current features.
So yeah… In the last post I used some low-resolution DVR footage for doing a proof of concept using a quick and dirty Blender project. In that post I naively thought that synchronizing gyro data with the footage wouldn't be too difficult. After getting access to some test footage (thanks to agent_d00nut, kyleli, and muteFPV!), and finding some example GoPro footage online, I've come to realize that perfect synchronization is absolutely critical. An offset of a couple of frames can exaggerate camera shake instead of removing it (this wasn't noticeable in the DVR). Moreover, logging rates aren't perfectly accurate, so matching a single point between footage and gyro data isn't enough. Doing this manually is extremely tedious.
This example took around an hour of tweaking to get a decent synchronization. The way forward is thus automatic synchronization. It also turns out that lens correction and calibration is required for proper and seamless stabilization. For instance, the result of wide-angle lens tilted 10 degrees will look nothing a zoom lens tilted the same amount. This also explains the wobbling in the example video.
During my research about video stabilization methods I found his paper by Karpenko et al. detailing a method of doing video stabilization and rolling shutter correction using gyroscopes with some very concise MATLAB code. While not exactly a step by step tutorial for beginners as I had jokingly hoped, I was still able to gather the overall ideas. The paper served as a springboard for further research, which lead me to learning and reading about quaternions, SLERP, camera matrices, image projections etc.
Instead of Blender, I have moved over to using OpenCV and Python for image processing, and Pyside2 for UI. OpenCV is used for computer vision and contains a bunch of features for video analysis and image processing. I'm just using Python since that's what I'm most familiar with. Hopefully, performance isn't too big of an issue since both OpenCV and Numpy are designed to be fast.
Here's what I've worked on since the last post:
All of this can be found in the Github repository. Feel free to take a peek, I've tried to keep the code nice and readable.
The plan moving forward is to focus on developing a working stabilization program for GoPro footage with embedded gyro metadata. This is something we know can work from reelsteady. Afterwards, support for blackbox log can be implemented, which should in theory just be a coordinate transformation to account for camera orientation and uptilt from what I can tell. If only the former works, at least there will be a (probably inferior) open source alternative to Reelsteady :).
My current plan for the gyro synchronization is to use the included optical flow functions in OpenCV to estimate camera movement, and "slide" the gyro data around until the difference is minimized, similar to the way Karpenko et al. does it. Doing this at two separate points in the video should be enough to compute clock offsets and get the best fit.
When the synchronization works, a low pass filter can be used to create a smooth virtual camera. A perspective transformation of the image plane can then be used to match the difference between the real and virtual camera. The image plane will essentially be "rotated" to match how it would look from the virtual camera, if that makes sense (more detail in the paper linked above for anyone interested). This virtual rotation only works with undistorted footage, hence the need for lens calibration. Another thing which may or may not be an issue is rolling shutter correction, but that'll have to wait until the other stuff works.
Some people asked for it last time, so I added a donate button on the Github page. You can throw a couple of bucks my way if you want (maybe that'll justify me getting a action camera myself for testing :) ), but be warned: While I'm optimistic, it's still not 100% certain that it will work with blackbox data as envisioned. GoPro metadata will probably work as mentioned before. Also, I've been kinda busy preparing for moving out/starting at uni next month, but I'll try to work on the project whenever I'm not procrastinating.

Problems getting Mediawiki VisualEditor to work

[SOLVED]
Hello,
after a long thread about documentation systems I am still looking for a wiki.
Bookstack and WikiJS both lack too many features.
So I decided to give Mediawiki a go, after having it suggested to me by several people.
It is installed on an Ubuntu 18.04 Virtual Machine with letsencrypt.
The installation of mediawiki was quite easy and straight forward.
I do not like markdown so a visual editor is a must have.
To me as beginner with very little wiki experience (only a bit of confluence) the structure both of mediwiki itself and the documentation is qute hard to grasp...
I checked out the VisualEditor page described in their wiki.
Then I installed parsoid from the apt repositories and configured the /etc/mediawiki/parsoid/config.yaml
[email protected]_mediawiki:~$ IFS=$'\n'; for i in $(cat /etc/mediawiki/parsoid/config.yaml | grep -v "#" | grep -v "^$");do echo " $i"; done| sed 's/****.\**/my\.domain/g' worker_heartbeat_timeout: 300000 logging: level: info services: - module: ../src/lib/index.js entrypoint: apiServiceWorker conf: mwApis: - uri: 'http://wiki.my.domain/w/api.php' serverPort: 8000 serverInterface: '127.0.0.1' 
Netstat shows port 8000 to be in use by nodejs and the systemd unitfile is running.
When trying to start the visual editor this is the error message I get:
Error loading data from server: apierror-visualeditor-docserver-http: HTTP 404. Would you like to retry? 
If I curl localhost/w/api.php I get a 404.
So I went ahead and checked the nginx sites-enabled conf.
Webroot is defined as /vawww/mediawiki/
There is a api.php in /vawww/mediawiki/ but there is no dir /vawww/mediawiki/w/...
Curl'ing localhost/api.php still gives me a 404.
I checked out thier Rest API Documentation.
It seems that I need to add IP (Install Path) to the LocalConfig.php...
[email protected]_mediawiki:~$ IFS=$'\n'; for i in $( cat /vawww/mediawiki/LocalSettings.php | grep -v "#" | grep -v "^$");do echo " $i"; done| sed 's/****.\**/my\.domain/g'  'http://localhost:8000', // Parsoid "domain", see below (optional) 'domain' => 'localhost', <------------- EDIT: THIS WAS THE ISSUE // Parsoid "prefix", see below (optional) 'prefix' => 'localhost' ); 
Do I maybe need to somehow "enable" the API somewhere or did I miss something else completely?
Feels like I could end up drowning countless hours into this without moving because I am missing some core knowledge here.
Thanks for your time in advance,
Ori
P.s.: I am still open for MediaWiki alternatives :)

rsync is a faster file transfer program for Unix to bring remote files into sync. It sends just the differences in the files across the link, without requiring both sets of files to be present at one of the ends. Suggested by zorinlynx, who adds that "rsync is GODLY for moving data around efficiently. And if an rsync is interrupted, just run it again."
Matter Wiki is a simple WYSIWYG wiki that can help teams store and collaborate. Every article gets filed under a topic, transparently, so you can tell who made what changes to which document and when. Thanks to bciar-iwdc for the recommendation.
LockHunter is a file unlocking tool that enables you to delete files that are being blocked for unknown reasons. Can be useful for fighting malware and other programs that are causing trouble. Deletes files into the recycle bin so you can restore them if necessary. Chucky2401 finds it preferable to Unlocker, "since I am on Windows 7. There are no new updates since July 2017, but the last beta was in June of this year."
aria2 is a lightweight multi-source command-line download utility that supports HTTP/HTTPS, FTP, SFTP, BitTorrent and Metalink. It can be manipulated via built-in JSON-RPC and XML-RPC interfaces. Recommended by jftuga, who appreciates it as a "cross-platform command line downloader (similar to wget or curl), but with the -x option can run a segmented download of a single file to increase throughput."
Free Services
Temp-Mail allows you to receive email at a temporary address that self-destructs after a certain period of time. Outwit all the forums, Wi-Fi owners, websites and blogs that insist you register to use them. Petti-The-Yeti says, "I don't give any company my direct email anymore. If I want to trial something but they ask for an email signup, I just grab a temporary email from here, sign up with it, and wait for the trial link or license info to come through. Then, you just download the file and close the website."
Duck DNS will point a DNS (sub domains of duckdns.org) to an IP of your choice. DDNS is a handy way for you to refer to a serverouter with an easily rememberable name for situations when the server's ip address will likely change. Suggested by xgnarf, who finds it "so much better for the free tier of noip—no 30-day nag to keep your host up."

They will then receive a link that will trigger the download directly from your computer, so the file does not have to be uploaded to the service itself. The link is good for one download and expires after 10 minutes. Thanks to cooljacob204sfw for the recommendation!
ShieldsUP is a quick but powerful internet security checkup and information service. It was created by security researcher Steve Gibson to scan ports and let you know which ones have been opened through your firewalls or NAT routers.
Firefox Send is an encrypted file transfer service that allows you to share files up to 2.5GB from any browser or an Android app. Uses end-to-end encryption to keep data secure and offers security controls you can set. You can determine when your file link expires, the number of downloads, and whether to add a password. Your recipient receives a link to download the file, and they don’t need a Firefox account. This one comes from DePingus, who appreciates the focus on privacy. "They have E2E, expiring links, and a clear privacy policy."
Free DNS is a service where programmers share domain names with one another at no cost. Offers free hosting as well as dynamic DNS, static DNS, subdomain and domain hosting. They can host your domain's DNS as well as allowing you to register hostnames from domains they're hosting already. If you don't have a domain, you can sign up for a free account and create up to 5 subdomains off the domains others have contributed and point these hosts anywhere on the Internet. Thanks to 0x000000000000004C (yes, that's a username) for the suggestion!
ANY.RUN is an interactive malware analysis service for dynamic and static research of the majority of threats in any environment. It can provide a convenient in-depth analysis of new, unidentified malicious objects and help with the investigation of incidents.

Plik is a scalable, temporary file upload system similar to wetransfer that is written in golang. Thanks go to I_eat_Narwhals for this one!
Free My IP offers free, dynamic DNS. This service comes with no login, no ads, no newsletters, no links to click and no hassle. Kindly suggested by Jack of All Trades.
Mailinator provides free, temporary email inboxes on a receive-only, attachment-free system that requires no sign-up. All @mailinator.com addresses are public, readable and discoverable by anyone at any time—but are automatically deleted after a few hours. Can be a nice option for times when you to give out an address that won't be accessible longterm. Recommended by nachomountain, who's been using it "for years."
Magic Wormhole is a service for sending files directly with no intermediate upload, no web interface and no login. When both parties are online you with the minimal software installed, the wormhole is invoked via command line identifying the file you want to send. The server then provides a speakable, one-time-use password that you give the recipient. When they enter that password in their wormhole console, key exchange occurs and the download begins directly between your computers. rjohnson99 explains, "Magic Wormhole is sort of like JustBeamIt but is open-source and is built on Python. I use it a lot on Linux servers."
EveryCloud's Free Phish is our own, new Phishing Simulator. Once you've filled in the form and logged in, you can choose from lots of email templates (many of which we've coped from what we see in our Email Security business) and landing pages. Run a one-off free phish, then see who clicked or submitted data so you can understand where your organization is vulnerable and act accordingly.

Tips
Here are a couple handy Windows shortcuts:
Here's a shortcut for a 4-pane explorer in Windows without installing 3rd-party software:
(Keep the win key down for the arrows, and no pauses.) Appreciation goes to ZAFJB for this one.
Our recent tip for a shortcut to get a 4-pane explorer in Windows, triggered this suggestion from SevaraB: "You can do that for an even larger grid of Windows by right-clicking the clock in the taskbar, and clicking 'Show windows side by side' to arrange them neatly. Did this for 4 rows of 6 windows when I had to have a quick 'n' dirty "video wall" of windows monitoring servers at our branches." ZAFJB adds that it actually works when you right-click "anywhere on the taskbar, except application icons or start button."
This tip comes courtesy of shipsass: "When I need to use Windows Explorer but I don't want to take my hands off the keyboard, I press Windows-E to launch Explorer and then Ctrl-L to jump to the address line and type my path. The Ctrl-L trick also works with any web browser, and it's an efficient way of talking less-technical people through instructions when 'browse to [location]' stumps them."
Clear browser history/cookies by pressing CTRL-SHIFT-DELETE on most major browsers. Thanks go to synapticpanda, who adds that this "saves me so much time when troubleshooting web apps where I am playing with the cache and such."
To rename a file with F2, while still editing the name of that file: Hit TAB to tab into the renaming of the next file. Thanks to abeeftaco for this one!
Alt-D is a reliable alternative to Ctrl-L for jumping to the address line in a browser. Thanks for this one go to fencepost_ajm, who explains: "Ctrl-L comes from the browser side as a shortcut for Location, Alt-D from the Windows Explorer side for Directory."
Browser shortcut: When typing a URL that ends with dot com, Ctrl + Enter will place the ".com" and take you to the page. Thanks to wpierre for this one!
This tip comes from anynonus, as something that daily that saves a few clicks: "Running a program with ctrl + shift + enter from start menu will start it as administrator (alt + y will select YES to run as admin) ... my user account is local admin [so] I don't feel like that is unsafe"
Building on our PowerShell resources, we received the following suggestion from halbaradkenafin: aka.ms/pskoans is "a way to learn PowerShell using PowerShell (and Pester). It's really cool and a bunch of folks have high praise for it (including a few teams within MSFT)."
Keyboard shortcut: If you already have an application open, hold ctrl + shift and middle click on the application in your task bar to open another instance as admin. Thanks go to Polymira for this one.
Remote Server Tip: "Critical advice. When testing out network configuration changes, prior to restarting the networking service or rebooting, always create a cron job that will restore your original network configuration and then reboot/restart networking on the machine after 5 minutes. If your config worked, you have enough time to remove it. If it didn't, it will fix itself. This is a beautifully simple solution that I learned from my old mentor at my very first job. I've held on to it for a long time." Thanks go to FrigidNox for the tip!

This security training slideshow was created for use during a quarterly infosec class. The content is offered generously by shalafi71, who adds, "Take this as a skeleton and flesh it out on your own. Take an hour or two and research the things I talk about. Tailor this to your own environment and users. Make it relevant to your people. Include corporate stories, include your audience, exclude yourself. This ain't about how smart you are at infosec, and I can't stress this enough, talk about how people can defend themselves. Give them things to look for and action they can take. No one gives a shit about your firewall rules."

Sometimes the best things in life are free, like these great Mac apps!


Get the greatest free apps on your Mac without having to dig through the entire Mac App Store!
The Mac App Store is full of all manner of apps, from simple utilities to complex programs. New apps are published every day, making it hard to find the best of the best — which is where we come in. We've gathered the best free apps for the Mac, all in one place so you don't have to go digging.

My criteria for apps on this list

In researching the best free apps for the Mac, I started by using Apple's category list. This makes it easier to cover the wide variety of content available. If an app is on the Mac App Store, it is in one of the 21 categories that Apple has listed.
Because this is a "free" app list, I tried to only include apps that are truly free or whose functionality is not diminished without an in-app purchase. You will see some apps that have premium content that can be unlocked with an in-app purchase, but I've included them on the list because I feel that the free content is noteworthy.
Since this is a list of apps, I'm not including services that only have websites without a dedicated app (there are two exceptions to this rule on the list, but they are totally worthy of rule-bending).
I've included some apps that are not available in the Mac App Store. That's because some of the best apps in a given category are so much better than any Mac App Store counterpart that I couldn't exclude them.
Though this list is long, it is by no means complete. There are just too many free Mac apps available to include everything. If you don't see your favorite free Mac app on this list, please add it in the comments section with your reason for why it stands out. (Remember: It has to be truly free or the free version of an otherwise premium app that is noteworthy.)

Business

Slack


Slack is a must-have app for anyone working remotely with others. It is the best business chat app around. The Mac app is a chat window, so you can keep your conversations going without having to log into a web browser every time. You can have multiple accounts running at the same time and there are dozens of helpful bots that you can add to any chat room.

Wave


Wave is one of those exceptions to the rule of no services without a dedicated app. It is a free software tool for small businesses. You can use it for invoicing, receipts, accounting, and more. You can also add credit card processing and payroll for a small additional fee. It is set up to work with what your business needs are. If you don't need a feature, you aren't paying for it. If you only need a feature sometimes, you only pay when you use it. Because Wave is dedicated to making small business tools work the way small business owners need them to, I've included it on this list.

Developer tools

Xcode


Xcode is the macOS, iOS, tvOS, and watchOS developer's handiest tool. It supports coding for Swift, Objective-C, Python, and a whole lot more. It can build universal binary files to run on PowerPC and Intel-based computers, and developers can create apps for 32-bit and 64-bit architectures. It's got everything an Apple coder needs.

Education

Khan Academy


Khan Academy is another exception to my rule that a service must have a dedicated app, but it is such a fantastic learning website, rich with online study courses of all levels — for free — that I had to include it. You can learn the colors of the rainbow or the Pythagorean Theorem. It covers basic subjects and works you into deeper involvement, just like you would start off taking basic classes in school and move into more advanced curricula. You can also prepare for the SAT, MCAT, GMAT, IIT JEE, and NCLEX-RN with excellent study guides. It is a great resource for getting started or back into your education.

Entertainment

Spotify


If you're not using Apple Music (actually, even if you are), Spotify is the next best music streaming service for the Mac. With the Mac app, you can listen to thousands of songs across all genres. It includes a useful playlist section so you can keep track of your favorite music. It also has a great music discovery section where you can see what's trending or music you might like based on what you've been listening to. The social aspect makes it one of my favorite free social media apps for the iPhone, too.

Finance

Debit & Credit - Personal Finance


If you prefer to keep track of your finances manually, Debit & Credit is a great checkbook balancing app (I know, no one balances a checkbook anymore). You manually enter every transaction and income, and you can keep track of what you're spending with the budget list. The report feature is the best. You can view your spending habits by category, where you spend, your income and expenses differences, whether you are able to save, and more. There is an in-app purchase to unlock more than two accounts, but if you only have two bank accounts, you don't need the premium service.

Money Wiz 2 ~ Personal Finance


Money Wiz is a great personal finance tracker for balancing your bank account. The free version lets you manually add account information like income, expenses, and account transfers. If you sign up for the monthly subscription, you can connect your online bank accounts and have the work done for you.

You can also set up a schedule reminder to keep you on track for paying bills that are due at the same time each month. It features a few more customizable features, like creating a new category for income and expenses, as well as creating financial reports based on your net worth, cash flow, and balance over time. Money Wiz works better with the subscription upgrade, but is very useful for keeping your checking accounts balanced.

Graphics & Design

GIMP


GIMP is pretty much the open-source version of Photoshop. You can fix minor photo errors, like light balance and contrast, or manipulate your image using the masking and removing features, similar to that of Photoshop's.

Health & Fitness

Time Out - Break Reminders


Taking a moment for oneself is one of the most difficult health and fitness steps to take. We get so caught up with our busy schedules that we forget to stop for a moment. Time Out forces you to take those little breaks by dimming your screen so you can't use it for a specified amount of time. You can set up small breaks every hour, micro-breaks every 15 minutes, and lunch breaks to get your eyes off the screen for a half-hour or so. You can configure how long the breaks are and how often you take them. It'll make your eyes, your muscles, and your heart a little bit healthier every day you use it.

It is very easy to use, so you don't have to be a professional recording artist to get into it.

DJ programs can be a pain in the pocketbook. If you're just learning the ropes or want to have a homegrown dance party, don't spend the heavy cash. Cross DJ makes it possible for you to spin the beats without the expensive software. It features waveforms, beat sync, track cueing, loops, digital scratching, and more. It accesses your iTunes library directly, so you don't even have to load up new music. You may eventually upgrade to a more robust DJ app, but this is definitely a great starter program.

Polarr is a basic photo editing app with excellent tools for image adjusting. You can adjust color, light, clarity, highlights, shadows, and more.

Apple Maps


Apple's built-in mapping service is really convenient to have on the Mac. You may not realize how often you look up the location of something while on your computer, but it is a fairly common occurrence, at least for me. Having Maps integrated with every aspect of your Mac makes it easy to look up directions from anywhere, like an email, a website, or a contact card. Siri can use Apple Maps to help you find all manner of locations in just a few seconds. It's already on your Mac and works great with all of the other built-in apps, too.

Google Earth


You may think of Google Maps as a means to get from point A to point B, but there is so much more to discover on this big blue marble than just driving directions. You can virtually travel the globe, visiting cities you'll never get to in real life. Walk around Manhattan with Street View, visit the swelling seas, and even look up to see the stars above you. With the time travel feature, you can go back decades to see what your house looked like, long before you lived there. Google Earth is less of a mapping service and more like a wealth of global information at your fingertips

It quickly unzips compressed and archived files from a number of different sources, including Zip RAR, 7-zip, and more, and it will open older archives from Stuffit, ARC and ISO disc images. As easy as it is to use Apple's Archive utility to simply unzip large files, the Unarchiver takes care of older content that can be a real pain to get open, since it uses smart detection to encode files correctly so that you won't end up with a bunch of garbled text. It is a fantastic secondary utility for opening files on your Mac.

IT Pro Tuesday #64 (part 2) - Mega List of Tips, Tools, Books, Blogs & More

(continued from part 1)
Captura is a flexible tool for capturing your screen, audio, cursor, mouse clicks and keystrokes. Features include mixing audio recorded from microphone and speaker output, command-line interface, and configurable hotkeys. Thanks to jantari for the recommedation.
Unlocker is a tool to help delete those irritating locked files that give you an error message like "cannot delete file" or "access is denied." It helps with killing processes, unloading DLLs, deleting index.dat files, as well as unlocking, deleting, renaming, and moving locked files—typically without requiring a reboot.
IIS Crypto's newest version adds advanced settings; registry backup; new, simpler templates; support for Windows Server 2019 and more. This tool lets you enable or disable protocols, ciphers, hashes and key exchange algorithms on Windows and reorder SSL/TLS cipher suites from IIS, change advanced settings, implement best practices with a single click, create custom templates and test your website. Available in both command line and GUI versions.
RocketDock is an application launcher with a clean interface that lets you drag/drop shortcuts for easy access and minimize windows to the dock. Features running application indicators, multi-monitor support, alpha-blended PNG and ICO icons, auto-hide and popup on mouse over, positioning and layering options. Fully customizable, portable, and compatible with MobyDock, ObjectDock, RK Launcher and Y'z Dock skins. Works even on slower computers and is Unicode compliant. Suggested by lieutenantcigarette: "If you like the dock on MacOS but prefer to use Windows, RocketDock has you covered. A superb and highly customisable dock that you can add your favourites to for easy and elegant access."
Baby FTP Server offers only the basics, but with the power to serve as a foundation for a more-complex server. Features include multi-threading, a real-time server log, support for PASV and non-PASV mode, ability to set permissions for download/upload/rename/delete/create directory. Only allows anonymous connections. Our thanks to FatherPrax for suggesting this one.
Strace is a Linux diagnostic, debugging and instructional userspace tool with a traditional command-line interface. Uses the ptrace kernel feature to monitor and tamper with interactions between processes and the kernel, including system calls, signal deliveries and changes of process state.
exa is a small, fast replacement for ls with more features and better defaults. It uses colors to distinguish file types and metadata, and it recognizes symlinks, extended attributes and Git. All in one single binary. phils_lab describes it as "'ls' on steroids, written in Rust."
rsync is a faster file transfer program for Unix to bring remote files into sync. It sends just the differences in the files across the link, without requiring both sets of files to be present at one of the ends. Suggested by zorinlynx, who adds that "rsync is GODLY for moving data around efficiently. And if an rsync is interrupted, just run it again."
Matter Wiki is a simple WYSIWYG wiki that can help teams store and collaborate. Every article gets filed under a topic, transparently, so you can tell who made what changes to which document and when. Thanks to bciar-iwdc for the recommendation.
LockHunter is a file unlocking tool that enables you to delete files that are being blocked for unknown reasons. Can be useful for fighting malware and other programs that are causing trouble. Deletes files into the recycle bin so you can restore them if necessary. Chucky2401 finds it preferable to Unlocker, "since I am on Windows 7. There are no new updates since July 2017, but the last beta was in June of this year."
aria2 is a lightweight multi-source command-line download utility that supports HTTP/HTTPS, FTP, SFTP, BitTorrent and Metalink. It can be manipulated via built-in JSON-RPC and XML-RPC interfaces. Recommended by jftuga, who appreciates it as a "cross-platform command line downloader (similar to wget or curl), but with the -x option can run a segmented download of a single file to increase throughput."
Free Services
Temp-Mail allows you to receive email at a temporary address that self-destructs after a certain period of time. Outwit all the forums, Wi-Fi owners, websites and blogs that insist you register to use them. Petti-The-Yeti says, "I don't give any company my direct email anymore. If I want to trial something but they ask for an email signup, I just grab a temporary email from here, sign up with it, and wait for the trial link or license info to come through. Then, you just download the file and close the website."
Duck DNS will point a DNS (sub domains of duckdns.org) to an IP of your choice. DDNS is a handy way for you to refer to a serverouter with an easily rememberable name for situations when the server's ip address will likely change. Suggested by xgnarf, who finds it "so much better for the free tier of noip—no 30-day nag to keep your host up."
Joe Sandbox detects and analyzes potential malicious files and URLs on Windows, Android, Mac OS, Linux and iOS for suspicious activities. It performs deep malware analysis and generates comprehensive and detailed reports. The Community Edition of Joe Sandbox Cloud allows you to run a maximum of 6 analyses per month, 3 per day on Windows, Linux and Android with limited analysis output. This one is from dangibbons94, who wanted to "share this cool service ... for malware analysis. I usually use Virus total for URL scanning, but this goes a lot more in depth. I just used basic analysis, which is free and enough for my needs."
Hybrid Analysis is a malware analysis service that detects and analyzes unknown threats for the community. This one was suggested by compupheonix, who adds that it "gets you super detailed reports... it's about the most fleshed out and detailed one I can find."
JustBeamIt is a file-transfer service that allows you to send files of any size via a peer-to-peer streaming model. Simply drag and drop your file and specify the recipient's email address. They will then receive a link that will trigger the download directly from your computer, so the file does not have to be uploaded to the service itself. The link is good for one download and expires after 10 minutes. Thanks to cooljacob204sfw for the recommendation!
ShieldsUP is a quick but powerful internet security checkup and information service. It was created by security researcher Steve Gibson to scan ports and let you know which ones have been opened through your firewalls or NAT routers.
Firefox Send is an encrypted file transfer service that allows you to share files up to 2.5GB from any browser or an Android app. Uses end-to-end encryption to keep data secure and offers security controls you can set. You can determine when your file link expires, the number of downloads, and whether to add a password. Your recipient receives a link to download the file, and they don’t need a Firefox account. This one comes from DePingus, who appreciates the focus on privacy. "They have E2E, expiring links, and a clear privacy policy."
Free DNS is a service where programmers share domain names with one another at no cost. Offers free hosting as well as dynamic DNS, static DNS, subdomain and domain hosting. They can host your domain's DNS as well as allowing you to register hostnames from domains they're hosting already. If you don't have a domain, you can sign up for a free account and create up to 5 subdomains off the domains others have contributed and point these hosts anywhere on the Internet. Thanks to 0x000000000000004C (yes, that's a username) for the suggestion!
ANY.RUN is an interactive malware analysis service for dynamic and static research of the majority of threats in any environment. It can provide a convenient in-depth analysis of new, unidentified malicious objects and help with the investigation of incidents. ImAshtonTurner appreciates it as "a great sandbox tool for viewing malware, etc."
Plik is a scalable, temporary file upload system similar to wetransfer that is written in golang. Thanks go to I_eat_Narwhals for this one!
Free My IP offers free, dynamic DNS. This service comes with no login, no ads, no newsletters, no links to click and no hassle. Kindly suggested by Jack of All Trades.
Mailinator provides free, temporary email inboxes on a receive-only, attachment-free system that requires no sign-up. All @mailinator.com addresses are public, readable and discoverable by anyone at any time—but are automatically deleted after a few hours. Can be a nice option for times when you to give out an address that won't be accessible longterm. Recommended by nachomountain, who's been using it "for years."
Magic Wormhole is a service for sending files directly with no intermediate upload, no web interface and no login. When both parties are online you with the minimal software installed, the wormhole is invoked via command line identifying the file you want to send. The server then provides a speakable, one-time-use password that you give the recipient. When they enter that password in their wormhole console, key exchange occurs and the download begins directly between your computers. rjohnson99 explains, "Magic Wormhole is sort of like JustBeamIt but is open-source and is built on Python. I use it a lot on Linux servers."
EveryCloud's Free Phish is our own, new Phishing Simulator. Once you've filled in the form and logged in, you can choose from lots of email templates (many of which we've coped from what we see in our Email Security business) and landing pages. Run a one-off free phish, then see who clicked or submitted data so you can understand where your organization is vulnerable and act accordingly.
Hardening Guides
CIS Hardening Guides contain the system security benchmarks developed by a global community of cybersecurity experts. Over 140 configuration guidelines are provided to help safeguard systems against threats. Recommended by cyanghost109 "to get a start on looking at hardening your own systems."

Good format for learning too. Most podcasts are about 8-15 mins long and its 'usually' an exam topic. It will be something like "HSPR" but instead of just explaining it super boring like Ben Stein reading a powerpoint, he usually goes into a story about how (insert time in his career) HSPR would have been super useful..."

Tips
Here are a couple handy Windows shortcuts:
Here's a shortcut for a 4-pane explorer in Windows without installing 3rd-party software:
(Keep the win key down for the arrows, and no pauses.) Appreciation goes to ZAFJB for this one.
Our recent tip for a shortcut to get a 4-pane explorer in Windows, triggered this suggestion from SevaraB: "You can do that for an even larger grid of Windows by right-clicking the clock in the taskbar, and clicking 'Show windows side by side' to arrange them neatly. Did this for 4 rows of 6 windows when I had to have a quick 'n' dirty "video wall" of windows monitoring servers at our branches." ZAFJB adds that it actually works when you right-click "anywhere on the taskbar, except application icons or start button."
This tip comes courtesy of shipsass: "When I need to use Windows Explorer but I don't want to take my hands off the keyboard, I press Windows-E to launch Explorer and then Ctrl-L to jump to the address line and type my path. The Ctrl-L trick also works with any web browser, and it's an efficient way of talking less-technical people through instructions when 'browse to [location]' stumps them."
Clear browser history/cookies by pressing CTRL-SHIFT-DELETE on most major browsers. Thanks go to synapticpanda, who adds that this "saves me so much time when troubleshooting web apps where I am playing with the cache and such."
To rename a file with F2, while still editing the name of that file: Hit TAB to tab into the renaming of the next file. Thanks to abeeftaco for this one!
Alt-D is a reliable alternative to Ctrl-L for jumping to the address line in a browser. Thanks for this one go to fencepost_ajm, who explains: "Ctrl-L comes from the browser side as a shortcut for Location, Alt-D from the Windows Explorer side for Directory."
Browser shortcut: When typing a URL that ends with dot com, Ctrl + Enter will place the ".com" and take you to the page. Thanks to wpierre for this one!
This tip comes from anynonus, as something that daily that saves a few clicks: "Running a program with ctrl + shift + enter from start menu will start it as administrator (alt + y will select YES to run as admin) ... my user account is local admin [so] I don't feel like that is unsafe"
Building on our PowerShell resources, we received the following suggestion from halbaradkenafin: aka.ms/pskoans is "a way to learn PowerShell using PowerShell (and Pester). It's really cool and a bunch of folks have high praise for it (including a few teams within MSFT)."
Keyboard shortcut: If you already have an application open, hold ctrl + shift and middle click on the application in your task bar to open another instance as admin. Thanks go to Polymira for this one.
Remote Server Tip: "Critical advice. When testing out network configuration changes, prior to restarting the networking service or rebooting, always create a cron job that will restore your original network configuration and then reboot/restart networking on the machine after 5 minutes. If your config worked, you have enough time to remove it. If it didn't, it will fix itself. This is a beautifully simple solution that I learned from my old mentor at my very first job. I've held on to it for a long time." Thanks go to FrigidNox for the tip!
Websites
Deployment Research is the website of Johan Arwidmark, MS MVP in System Center Cloud and Datacenter Management. It is dedicated to sharing information and guidance around System Center, OS deployment, migration and more. The author shares tips and tricks to help improve the quality of IT Pros’ daily work.
Next of Windows is a website on (mostly) Microsoft-related technology. It's the place where Kent Chen—a computer veteran with many years of field experience—and Jonathan Hu—a web/mobile app developer and self-described "cool geek"—share what they know, what they learn and what they find in the hope of helping others learn and benefit.
High Scalability brings together all the relevant information about building scalable websites in one place. Because building a website with confidence requires a body of knowledge that can be slow to develop, the site focuses on moving visitors along the learning curve at a faster pace.
Information Technology Research Library is a great resource for IT-related research, white papers, reports, case studies, magazines, and eBooks. This library is provided at no charge by TradePub.com. GullibleDetective tells us it offers "free PDF files from a WIIIIIIDE variety of topics, not even just IT. Only caveat: as its a vendor-supported publishing company, you will have to give them a bit of information such as name, email address and possibly a company name. You undoubtedly have the ability to create fake information on this, mind you. The articles range from Excel templates, learning python, powershell, nosql etc. to converged architecture."
SS64 is a web-based reference guide for syntax and examples of the most-common database and OS computing commands. Recommended by Petti-The-Yeti, who adds, "I use this site all the time to look up commands and find examples while I'm building CMD and PS1 scripts."
Phishing and Malware Reporting. This website helps you put a stop to scams by getting fraudulent pages blocked. Easily report phishing webpages so they can be added to blacklists in as little as 15 minutes of your report. "Player024 tells us, "I highly recommend anyone in the industry to bookmark this page...With an average of about 10 minutes of work, I'm usually able to take down the phishing pages we receive thanks to the links posted on that website."
A Slack Channel
Windows Admin Slack is a great drive-by resource for the Windows sysadmin. This team has 33 public channels in total that cover different areas of helpful content on Windows administration.
Blogs
KC's Blog is the place where Microsoft MVP and web developer Kent Chen shares his IT insights and discoveries. The rather large library of posts offer helpful hints, how-tos, resources and news of interest to those in the Windows world.
The Windows Server Daily is the ever-current blog of technologist Katherine Moss, VP of open source & community engagement for StormlightTech. Offers brief daily posts on topics related to Windows server, Windows 10 and Administration.
An Infosec Slideshow
This security training slideshow was created for use during a quarterly infosec class. The content is offered generously by shalafi71, who adds, "Take this as a skeleton and flesh it out on your own. Take an hour or two and research the things I talk about. Tailor this to your own environment and users. Make it relevant to your people. Include corporate stories, include your audience, exclude yourself. This ain't about how smart you are at infosec, and I can't stress this enough, talk about how people can defend themselves. Give them things to look for and action they can take. No one gives a shit about your firewall rules."
Tech Tutorials
Tutorialspoint Library. This large collection of tech tutorials is a great resource for online learning. You'll find nearly 150 high-quality tutorials covering a wide array of languages and topics—from fundamentals to cutting-edge technologies. For example, this Powershell tutorial is designed for those with practical experience handling Windows-based Servers who want to learn how to install and use Windows Server 2012.
The Python Tutorial is a nice introduction to many of Python’s best features, enabling you to read and write Python modules and programs. It offers an understanding of the language's style and prepares you to learn more about the various Python library modules described in 'The Python Standard Library.' Kindly suggested by sharjeelsayed.
SysAdmin Humor
Day in the Life of a SysAdmin Episode 5: Lunch Break is an amusing look at a SysAdmin's attempt to take a brief lunch break. We imagine many of you can relate!
Have a fantastic week and as usual, let me know any comments.
