This article offers the option to either use the install script or use the manual steps listed below. Before you begin, check the prerequisites.

Minimum OS supported versions:

CentOS 7
RHEL 8
Any modern Debian-based OS (Ubuntu)

Prerequisites:

User Directory connector token
Directory Provider authorization token. See CloudGen Access User Directory Connector for more information.

Install Script

The steps below will download and execute a script automatically. Barracuda Networks recommends that you inspect the content before execution.
The script will install and enable a chrony service for time synchronization. This is required to ensure tokens are validated properly.
IMPORTANT: Tokens are valid for approximately 10 days, and updating the token is an automated process; however, it is possible for this process to not complete properly. The result is that the token expires and new users/groups are not synchronized as expected. To avoid this issue, you can manually redeploy the token.

Download and execute the installation script:

sudo bash -c "$(curl -fsSL https://url.access.barracuda.com/connector-linux)"

This script can also be used for unattended installations:

curl -fsSLo install-connector-linux.sh https://url.access.barracuda.com/connector-linuxchmod +x install-connector-linux.sh./install-connector-linux.sh -hInstall CloudGen Access User Directory Connector scriptAvailable parameters: -e - Extra connector environment variables (can be used multiple times) -h - Show this help -l string - Loglevel (debug, info, warning, error, critical), defaults to info. -n - Don't start services after install -t token - Specify CloudGen Access Connector enrollment token -u - Unattended install, skip requesting input <optional> -z - Skip configuring ntp server <optional>

Example for unattended installation with CloudGen Access Connector enrollment token and Azure directory

Specify the token s inside quotes :

./ install-connector-linux.sh -u -t "https://xxxxxxxxxxxx" -e "FYDE_AZURE_AUTH_TOKEN=xxxxxxxx"
