Configuration with sysctl
The Linux kernel can be configured in different ways. The first one is to enable or disable particular settings during the compilation. This is typically the work done by your Linux distribution. A more accessible method to change how your kernel should behave, is by using sysctl. This command tells the kernel to change a setting while it is running. The configuration can also be saved to /etc/sysctl.conf. This file is also when the system is starting up.
