The managed host downloads the job “payload” via HTTPS from the Capsule server.A managed host receives MQTT notification that there is a new REX job.Managed hosts subscribe to the MQTT broker to receive REX job notifications. Remote execution pull mode uses Message Queuing Telemetry Transport (MQTT) to publish jobs on Capsule servers (or Capsule service running on a Satellite server). Port 22 must be open on hosts to enable REX. REX jobs are dispatched to hosts by the Capsule server (or Capsule service running on a Satellite server) using the Secure Shell (SSH) service.

Remote execution (or REX) enables you to run shell scripts, Ansible tasks, and Ansible Playbooks on remote hosts managed by Satellite.
