To install Sensei in OPNsense with the command line interface, you must use an administrative account with shell access.
Command Line Installation
The command line installation method was the primary means for installing Sensei before it was available on the “Plugins” page in the OPNsense web interface. This option is still available for users who have local access to the OPNsense system yet prefer using command line tools or who may only have remote shell access via SSH to administrate their OPNsense installations. However, the web interface will need utilized after installation to complete the initial configuration of Sensei.
Local System Access
When you have local access to OPNsense, you may simply log into OPNsense using the “root” user or another administrator account. You should see a list of OPNsense menu options.
SSH AccessIf you only have shell access to OPNsense, you may install Sensei remotely by logging into OPNsense using a SSH client using the following command where “root” is the administrator account and “your-firewall-ip” is the IP address or hostname of the OPNsense system. You should see a list of OPNsense menu options.
$ ssh [email protected]
Download & Run Sensei Installer
Once you are successfully logged into OPNsense either by local system access or SSH access, enter option “8” to open the shell. Run the following command to download and execute the installation script.
# curl https://updates.sunnyvalley.io/getsensei | sh
The script will copy the installation files onto the filesystem and will add a top-level menu item within the OPNsense web interface. Depending on the speed of your hardware and Internet connection, the installation may take several minutes to complete.
Once the installation has been completed, you may disconnect from your terminal session. You may also disable your firewall’s SSH service by unchecking the checkboxes mentioned above if you no longer wish to use the SSH service.
You will now need to complete the “Initial Configuration Wizard” for Sensei to be fully operational. To view the instructions, go to the "Initial Configuration Wizard" section of the web installation page.
