Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Sysctl is an interface for examining and dynamically changing parameters in the BSD and Linux operating systems. The implementation mechanism in these two systems is very different. In BSD these parameters are generally objects in a management information base (MIB) that describe tunable limits such as the size of a shared memory segment, the number of threads the operating system will use as an NFS client, or the maximum number of processes on the system; or describe, enable or disable behaviors such as IP forwarding, security restrictions on the superuser (the "securelevel"), or debugging output.
