Oracle Linux

Install the Sensor from Endura’s signed RPM repository on Oracle Linux.

Prerequisites

  • Oracle Linux 9 or 10
  • Root or sudo access and systemd
  • A supported Red Hat Compatible Kernel or Unbreakable Enterprise Kernel with BTF at /sys/kernel/btf/vmlinux
  • At least 1 GB of available memory
  • An Endura license key
  • Team Server URL and Sensor token for centralized management

Install 

curl -sSf https://repo.endurasecurity.com/install/endura-sensor/testing.sh | sudo -E sh
endura version
sudo systemctl status endura-sensor

The installer configures Endura’s signed RPM repository, installs endura-sensor, and creates the systemd service.

Configure

Edit /opt/endura/sensor/environ and set:

ENDURA_LICENSE_KEY=your_license_key
ENDURA_TEAM_SERVER=https://team-server.example.com
ENDURA_SENSOR_TOKEN=your_sensor_token

Create the token under Sensors in Team Server, then protect the file:

sudo chown root:root /opt/endura/sensor/environ
sudo chmod 600 /opt/endura/sensor/environ

See Configuration for optional variables.

Start and Verify 

sudo systemctl enable --now endura-sensor
sudo systemctl status endura-sensor
endura sensor status
endura license verify

Confirm the Sensor and deployment appear in Team Server when centrally managed.

Operate the Service 

sudo systemctl restart endura-sensor
sudo systemctl stop endura-sensor
sudo journalctl -u endura-sensor -f
sudo endura sensor hooks

Update 

sudo dnf upgrade endura-sensor
endura version
sudo systemctl status endura-sensor

The package restarts a Sensor that was running before the update. Review Team Server Compatibility before a major update.

Uninstall 

sudo dnf remove endura-sensor

Back up and remove /opt/endura/sensor or /var/log/endura separately only when their data is no longer needed.

Troubleshooting

Service Does Not Start 

sudo systemctl status endura-sensor --full
sudo journalctl -u endura-sensor -n 100
test -r /sys/kernel/btf/vmlinux && echo "BTF available"
uname -r

Check the first startup error, license, file permissions, and SELinux denials. If the host uses UEK or Ksplice, confirm the running kernel still exposes the required BTF and hooks.

Team Server Is Offline 

curl -v https://team-server.example.com/_readiness
getent hosts team-server.example.com

Confirm outbound TCP 443 and certificate trust. See Team Server Compatibility for an incompatible state.

Package or Kernel Changed 

sudo dnf repolist
sudo dnf info endura-sensor
sudo endura sensor hooks

Recheck hook coverage after UEK, RHCK, or Ksplice changes.
