App Control: How to Install and Upgrade Linux Agents

[#1]

Environment

• App Control Agent: All Supported Versions
• Linux: All Supported Versions

Objective

To upgrade or install an App Control Agent on a Linux endpoint.

Resolution

Installation:
This procedure (and any installation involving b9install.sh) should be used only when the Linux Agent is otherwise fully removed from the endpoint.

1. Navigate to https://ServerAddress/hostpkg and download the relevant Linux install package.
2. Extract the Agent installer:

   tar -xvzf <policyname>-Red Hat.tgz

   • Note: If the Policy name contains characters not accepted in command arguments, such as spaces or parentheses, escape each character with a backslash.
3. Change to the directory matching the download tarball name:

   cd <policyname>-Red Hat

   • Note: App Control Server versions 8.9.0 and lower will require the App Control SHA256 based Public Key as bit9cs_sha2.asc in the same folder as b9install.sh.
4. Validate the b9install script with Public Key and Detached Signature:
5. Install the Agent:

   With Notifier: sudo sh ./b9install.sh
   Without Notifier: sudo sh ./b9install.sh –n

Manually Upgrade:

1. Temporarily disable the Agent's Tamper Protection.
2. Download the relevant Agent Upgrade package to the endpoint: https://ServerAddress/hostpkg/pkg.php?pkg=Bit9RedHat{6,7,8 or 9}Install.bsx

   RHEL 8 Example: https://ServerAddress/hostpkg/pkg.php?pkg=Bit9RedHat8Install.bsx

3. Using Terminal change directory to the download location and issue the upgrade command:

   sudo bash Bit9Redhat{6,7,8,9}Install.bsx
