Mr Cook, I think that you're right, because sysctl command
works very well: now, dmesg is restricted for normal user.
Why it is not set by default? I mean this dmesg restrict.
It seems, that it has a large impact on system security, right?

Mr Jamie. You have written, that to make this change persistent
I should create/edit a file in /etc/sysctl.d/ directory. Can I simply,
set this option, in the /etc/sysctl.conf file? It seems easier.
And yes, I tried echoing '1' into the file with 'sudo echo 1 > ...' command.
This command caused the 'permission denied' message.

So, "problem" seems to be Solved. Thank you for attention and suggestions.

Best regards Mr Kees and Mr Jamie.
