Some Linux distributions (e.g. Redhat, Centos) send kernel warnings directly to the systems console. For example, these distributions may send to the console firewall log events (e.g. iptables, ipset) and kernel security enhancement messages (e.g. Grsecurity, PAX). If you would like to prevent your distribution from doing this permanently, run this command as the root user:
echo "kernel.printk = 4 1 1 7" > /etc/sysctl.d/atomicorp.conf
This will configure the system to supress these messages in the future. To apply this setting to the system now, run this command as the root user:
sysctl -p /etc/sysctl.d/atomicorp.conf
