Once you install Ubuntu 18.04 some packages might not be found by default in repositories (example: php7.2-fpm).

If you want to have more packages available just add repository with more packages available 🙂

sudo add-apt-repository universe

Now you can enjoy more standard packages available.

After upgrading to macOS Mojave you might experience following error when trying to run some command line tools like git, for example:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

To resolve that run those commands in Terminal:

sudo xcode-select --switch /Applications/Xcode.app
sudo xcode-select --switch /Library/Developer/CommandLineTools

Issue should be resolved.

For testing purposes I deployed Microsoft AppV infrastructure.

Systems presented on diagram above:

• Core-DC-01 – Domain Controller – deployed prior to AppV installation
• Core-SQL-01 – SQL Server – deployed prior to AppV installation
• AppV-SRV-01 – AppV Management Server
• AppV-WKS-01 – AppV Sequencer Workstation

Installation process for systems listed above below.

By default elasticsearch has 2GB of RAM set for JVM. In case you run it on VM with less memory you need to change:

• –Xms2g to –Xms512m
• –Xmx2g to –Xmx512m

in /etc/elasticsearch/jvm.options configuration file.

In case Microsoft Compatibility Telemetry process takes a lot of your processor, you can easily remove it:

1. Run Command Prompt as Administrator.
2. Execute following commands in Command Prompt:

• sc delete DiagTrack
• sc delete dmwappushservice
• echo “” > C:\ProgramData\Microsoft\Diagnosis\ETLLogs\AutoLogger\AutoLogger-Diagtrack-Listener.etl
• reg add “HKLM\SOFTWARE\Policies\Microsoft\Windows\DataCollection” /v AllowTelemetry /t REG_DWORD /d 0 /f

Tomasz Jagiello strikes back as guest writer 🙂 This time on Windows Event Collector configuration for DNS Event Log forwarding. Very good how-to with detailed configuration.

Design where via Group Policy a Domain Controller group will be configured to forward DNS Server events to a single collector.

To test and demonstrate Event Log Forwarding I built simple Lab environment:

• 2x Domain Controllers (DC1, DC2)
• 1x Event Collector (SRV1).
