How to configure Debian to create new added users through adduser to be secure by default / Limiting access to other user’s information
Yep I just gave it a try, You’re right. the “-R” option is not necessary in the for loop. I’ve fixed that in the article.

Thanks for noting it!

Will be seeing you around,

Wish you best!

How to configure Debian to create new added users through adduser to be secure by default / Limiting access to other user’s information
Guess you’re right but yet, if only the users directory permissions are changed somebody could try to guess the user files and he will be able to read them if he is lucky. Thus it might be better that way sometimes.

       –rwo, –report-warnings-only
              This option causes only warning messages to be displayed. This can be useful when rkhunter is run via cron. Other options may
              be used to force other items of information to be displayed.

       –sk, –skip-keypress
              When  the  –check command option is used, after certain sections of tests, the user will be prompted to press the return key
              in order to continue. This option disables that feature, and rkhunter will run until all the tests have completed.
