NRPE 4.0.3 and the NSClient - CHECK_NRPE: Invalid packet ver

[benjaminsmith]

Hi @Support_Talea,

You can alter the check command by adding -2 option to use the version 2 packets.

See:

The issue here is with the Run Check Command feature in the GUI of the Core Configuration Manager. I would recommend testing from the CLI to verify the command for NSClient as a workaround.

If you continue to have issues, please open a separate forum topic.

Best Regards,
Benjamin
