  • When trying to execute the REX job on secondary interface of a content host, it fails with the following error in the Dynflow Console:

        proxy_task_id: 1b23v1-3abc-23gf-bdcd-a283578e17f0
    proxy_output:
      result:
      - output_type: debug
        Error initializing command: Errno::ECONNREFUSED - Connection refused - connect(2) for 192.xxx.0.xx:22  
    Exit status: EXCEPTION

Resolution

  • Enable the following setting from Red Hat Satellite GUI:

        - Administer > Settings > RemoteExecution > Fallback to Any Capsule = yes

  • Re-run REX job.

OR

  • The issue can be because of the failure in the DNS resolution of the secondary interface and thus it fallback to the primary interface and fails to connect.

  • Enable the following setting from Red Hat Satellite GUI:

        - Administer > Settings > RemoteExecution > Connect by IP = yes

  • Re-run REX job.

  • Setting Connect by IP to yes in Red Hat Satellite settings will allow the satellite to use the content host's IP to connect for the REX job and thus even if the DNS resolution fails, the satellite will connect with the content host using IP.
