Why?

Hi Neceel,

Those are HTTP commands GET within the network which leaked to dataTaker. There is a risk that the leaked message may imitate any logger commands (i.e.: H for halt which will stop the running job).

Thus it might be better to implement command interface password or dEX security if you see a lot of this type of messages in the event log.

Hi Rudy,

Hi Neceel,

You can enable command interface through dEX configuration page. Go to profile setting and set the setting under "Security" tab. Or if you use text program you can insert password syntax after BEGIN.

dEX security is a bit different, you must select the third option "Customised dEX" at dEX home page, then enable user level authentication under "Security" tab. But previously you may need to set/ create user role under "User Maintenance".

Please note dEX security precedents command security.
