Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

Edit or create a file in the /etc/audit/rules.d/ directory, ending in .rules extension, with the relevant rules to monitor login and logout events. Example: # printf " -w /var/log/lastlog -p wa -k logins -w /var/run/faillock -p wa -k logins " >> /etc/audit/rules.d/50-login.rules Merge and load the rules into active configuration: # augenrules --load Check if reboot is required. # if [[ $(auditctl -s | grep "enabled") =~ "2" ]]; then printf "Reboot required to load rules\n"; fi
