Unsupported shell '$0'. Supported shells

[balaji_prusty1]

Hi Team;

I am trying to discover HPE Blade device through SSH probe, which is giving below error.  But when it discover using SNMP it works fine. But our requirement is probe through SSH to get all the config. 

Unsupported shell '$0'. Supported shells are [tcsh, csh, ksh, sh, dsh, bash], and Bourne compatible shells in that list are specified by 'mid.ssh.shells_supported' (defaults to [ksh,sh,bash]).

Looking for help on this to fix?

Thanks in Advance.

HI @balaji_prusty1 ,
I trust you are doing great.

This error typically occurs when the SSH probe is attempting to connect to the device using a shell that is not supported or recognized by the probe. To resolve this issue, you'll need to ensure that the SSH probe is configured to use one of the supported shells mentioned in the error message.

To specify the supported shells for the SSH probe, you'll need to modify the 'mid.ssh.shells_supported' parameter in the ServiceNow instance. Here's an example of how you can do this using the ServiceNow Script Includes:

// Update SSH probe supported shells
var probe = new SshProbe(); // Replace 'SshProbe' with the actual name of your SSH probe
var supportedShells = ['tcsh', 'csh', 'ksh', 'sh', 'dsh', 'bash']; // Add or remove shells as needed
probe.setParameter('mid.ssh.shells_supported', supportedShells.join(','));
probe.update(); // Save the changes

// Run the SSH probe discovery again
var discovery = new Discovery(); // Replace 'Discovery' with the actual name of your Discovery object
var result = discovery.runProbe(probe); // Replace 'probe' with the actual name of your SSH probe

Hi Amit;

As per below KB article, I added 'mid.ssh.shells_supported' in mid-server configuration parameter. But still the same error.

As per your comments, which script include I need to update?

Thanks
