Kör nu föjande kommandon:
echo "*/5 * * * * root /etc/cron.mrtg/mrtg &>/dev/null" > /etc/cron.d/mrtg
chmod +x /etc/cron.mrtg/mrtg
chmod +x /etc/cron.d/mrtg

Kör nu /etc/cron.mrtg/mrtg om igen tills du inte längre får några felmeddelanden. (normalt 3-4 gånger)
Starta därefter om crontab:
/etc/init.d/cron restart
Nu ska allt funka som det skall.
