H.3. Brief introduction to sysctl

Many behaviours of the linux kernel can be modified through the use of run time variables. These variables can be changed manually or with the use of a convenient command line utility. Most linux distributions also include a standard configuration file which can store these parameters for use at boot time.

For a deeper reference into the matter and use of sysctl see the IP Sysctl tutorial, maintained by Oskar Andreasson.
