Ask questions about your servers, containers, and laptops running Linux, Windows, and macOS. Quickly deploy osquery and scale your fleet to 50,000+ devices on top of a stable core technology.
If you enabled Fleet during setup, you can then login to Fleet using the email address and password that you entered during the installer. You can edit the password or add a new Fleet user within Fleet itself.
Custom osquery packages are generated during setup and you can find them on the Downloads page in Security Onion Console (SOC). Before you install a package on an endpoint, use so-allow on your manager node to configure the firewall to allow inbound osquery connections.
Fleet configuration can be found in
/opt/so/conf/fleet/. However, please keep in mind that if you make any changes to this directory they may be overwritten since the configuration is managed with Salt.
Fleet logs can be found in
/opt/so/log/fleet/. Depending on what you’re looking for, you may also need to look at the Docker logs for the container:
sudo docker logs so-fleet
fleetctl is a command-line utility that allows you to manage your Fleet instance and run live queries from the cli.
fleetctl from the Manager and Fleet is enabled on the Manager, first set the
fleetctl login configuration:
./fleetctl config set --address https://localhost:8080 --url-prefix fleet --tls-skip-verify
Then login using a valid username and password:
fleetctl documentation can be found at https://fleetdm.com/docs/using-fleet/fleetctl-cli.
Adding Query Packs¶
You can bulk add queries and packs to FleetDM using fleetctl.
/opt/so/conf/fleet/packs/ is mapped to the FleetDM container, so you can drop your query packs there and then reference them like this:
sudo docker exec -it so-fleet fleetctl apply -f /packs/<yourpack>.yaml
Single queries and packs can also be added via the GUI in FleetDM. Go to the
Queries section, click the
Create New Query button, and add the query. Test the live query, verify that it works correctly, and save it. You can then either add it to an existing pack or create a new pack. Do this by going to the
Schedule section, choosing
Advanced, and using the options there. Your query will not work if it isn’t also scheduled, so set a short interval for testing, then update to a more sensible gap for production.
