rkhunter warns about chkconfig
Of regard; SSH was manually disabled on such stated device which might be the causation to the following or above SSH warning. When working through the associated Ubuntu article; updating RkHunter got rid of the first five errors on that of a second scan.
What would be to process to therein triaging or investigating the above listed warnings irrespective and if someone could point me to any associative help articles, such would be informative being somewhat new to Linux.
