How to Install GRR on OpenBSD

GRR is an open-source security automation and response platform developed by Google that is used for remote live forensics and data collection. In this tutorial, we will walk you through the steps to install GRR on OpenBSD.

Prerequisites

Before we proceed with the installation steps, make sure that your OpenBSD machine meets the following system requirements:

• OpenBSD 6.5 or later
• At least 2 CPU cores
• At least 4GB of RAM
• At least 20GB of disk space

Additionally, you will need an SSH client to log in to your OpenBSD machine and a web browser to access the GRR web interface.

Step 1 - Install Python and Dependencies

To install GRR on OpenBSD, you need to install Python and its dependencies. Run the following command to do so:

$ sudo pkg_add python-3.8.9

Step 2 - Download GRR

Download the latest version of GRR package by running the following command:

$ wget https://storage.googleapis.com/release.grr-response.com/grr-server/latest/grr-server_4.3.3_amd64.deb

Step 3 - Install GRR

After downloading the GRR package, run the following command to install the package:

$ sudo dpkg -i grr-server_4.3.3_amd64.deb

Step 4 - Configure GRR

Create a new configuration file for GRR by running the following command:

$ sudo nano /etc/grr/server.local.yaml

Paste the following configuration in the file:

AdminUI.url: http://SERVER_IP:8000
AdminUI.bind_port: 8000
AdminUI.headless: true
DataServer.fs_ntfs: true
DataServer.poll_min: 1
Logging.export_logs: true
Logging.trace_export: true
Logging.trace_export_limit: 5000000
Osquery.path: /usr/local/bin/osqueryi
UI.export_command: /grr/exported_plugins/grr_response_server/gui/ui/plugins/export_command.py

Replace SERVER_IP with the IP address of your OpenBSD machine.

Save and exit the file.

Step 5 - Start GRR

Start the GRR service by running the following command:

$ sudo /etc/rc.d/grr start

Step 6 - Access GRR

Open your web browser and navigate to http://SERVER_IP:8000. You should see the GRR login screen.

Log in with the default username and password:

• Username: admin
• Password: admin

After logging in, you can start using GRR for security automation and incident response.

Conclusion

In this tutorial, we have walked you through the steps to install GRR on OpenBSD. You can now use GRR for remote live forensics and data collection on your OpenBSD machine.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
