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.
- Navigate to https://ServerAddress/hostpkg and download the relevant Linux install package.
- 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.
- Change to the directory matching the download tarball name:
cd <policyname>-Red Hat
- Validate the b9install script against the Public Key and Detached Signature with the following commands:
gpg –-dearmor bit9cs_sha2.asc
gpg --no-default-keyring --homedir . --keyring bit9cs_sha2.asc.gpg --verify b9install.asc b9install.sh
- Note: The result should return similar: gpg: Good signature from "build (carbonblack)"
- Install the Agent:
With Notifier: sudo sh ./b9install.sh
Without Notifier: sudo sh ./b9install.sh –n
Manually Upgrade:
- Temporarily disable the Agent's Tamper Protection.
- 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
- Using Terminal change directory to the download location and issue the upgrade command:
sudo bash Bit9Redhat{6,7,8,9}Install.bsx
Additional Notes
- When installed without the Notifier, Agents in Medium Enforcement will be unable to prompt users to choose Allow or Block.
- Installation of the Agent on a RHEL 9.0 endpoint will require:
- App Control Server version 8.9.0 or later.
- Installation of the initscripts RPM manually, or connecting the host to the Red Hat Network.
