Severity

Fails health check for targets without Bash

Latest Version

I could reproduce the problem in the latest build

What happened?

When health checking a target where the machine policy is set to "Only perform connection test (useful for raw scripting)" it fails if bash is not available. This is unexpected as it should not be trying to run any scripts on the target.

This is for a SSH target. I have not checked if it applies to tentacle targets (or whether it should).

Reproduction

• Create a VM that does not have bash
• Enable SSH to that VM
• Configure a machine policy with Only perform connection test (useful for raw scripting)
• Create a SSH target for that machine with that machine policy
• Perform a health check

Error and Stacktrace

/bin/bash shell missing.
SSH connection disposed.
