batch_get_command_status doesn't return stderr when queued offline machine comes back and file does not exist

[jsdjjsd]

I'm using the batch_get_command class to schedule downloading of files from multiple machines over RTR. If a machine is online and the file does not exist it will return "Check your filename" as stderr. But if a machine is offline, and later comes back online, when using the batch_get_command_status class using batch_get_cmd_req_id from the initial request, the resulting stderr will stay empty. The only time the output of the batch_get_command_status request changes is if the file exists and has been downloaded and I get the sha256 field populated.

To reproduce this behaviour:

• Sleep target machine,
• Use batch_get_command to schedule a download of a file that does not exist on target machine,
• Wake target machine,
• Use batch_get_command_status and see that it never changes the output.

I would have thought that stderr would behave similarly as with batch_get_command, namely, return "Check your filename" if the file does not exist.

• OS: Target machine is Windows 10, machine that runs Python 3 and FalconPy is Ubuntu 22.04,
• Python: 3.10.6
• FalconPy: 1.2.4

As far as I understand from the documentation this is the intended way to go about this, but is there another way this is intended to work?

Hi @jsdjjsd -

The process you describe above appears correct. We're recreating this issue on our side to confirm, and will reply back here once we have more information.

Thank you for reporting this!!! 😃

Hi @jsdjjsd -

We believe we've identified the issue. BatchGetCmdStatus is not getting results as the upload never completes. (Results are recorded upon successful completion of the GET.)

If you instead try to use RTR_CheckCommandStatus (making sure to provide the individual task ID for this host) do you get the correct response?

Hi @jshcodes

Thanks for looking into this. I've tested your suggestion now and at first I couldn't get RTR_CheckCommandStatus to return anything useful using the session_id I get per resource from initiating the BatchGetCmd, but it seems that if I use task_id instead I get something useful back, namely that while the endpoint is offline I get complete: False and when it comes back online it returns the stderr I'm looking for. So if I just track the task_id from respective resource I should be fine.

Thanks!

That's my bad for giving you the wrong ID type. Updating the answer above for others. 😄
