SSH script with pfsense for temperature monitor

Hi Bitter,

Could you please forward the script as well as the output after activating the "Write Results to Disk Option" in the settings of the sensor. Thanks!

Best regards, Felix

Hi, thanks for reply. I have 3 different file of output, the big one is the following:

Data['CheckFlavor'].asString := '';
Data['DoNotCheckShell'].asString := '';
Data['UsedSha2'].asString := '1';
Data['blockedsens'].asString := '';
Data['canlinux'].asString := '0';
Data['channel'].asString := 'Value';

'1'#$D#$A + 
'';
Data['command'].asString := '/var/prtg/scripts/Warning: no access to tty (Bad file descriptor). ';
Data['deviceid'].asString := '2041';
Data['elevation'].asString := '0';

';
Data['sshencoding'].asString := '1';
Data['sshversion_devicegroup'].asString := '2';
Data['sshversion_sensor'].asString := '0';
Data['timeout'].asString := '60';
Data['tlsexplicit_default'].asString := '';

Data['uptimecount'].asString := '0';
Data['usednstime'].asString := '0';
Data['user'].asString := 'prtg';
Data['valuetype'].asString := '1';
Data['writeresult'].asString := '1';

I have read that the output of the script must be returncode:value:message

so I have edited my script as following echo 0:`sysctl -n dev.cpu.0.temperature | tr -d C`:Grad that returns: 0:45.0:Grad

But the error message is always the same.

Hey bitter,

Thanks for sharing your solution! I'm sure that this will help other customers in the future! Have a good day!

Best, Felix

How did you assign the rights? I'm getting the same error. I think its something to do with the shell presented when logging in to pfsense.

Hi Matt,

Did you already try using the root user to see if it works then?

Best regards, Felix
