NAME

       sysctl.conf - sysctl preload/configuration file

DESCRIPTION

       sysctl.conf  is  a  simple  file containing sysctl values to be read in and set by sysctl.
       The syntax is simply as follows:

              # comment
              ; comment

              token = value

       Note that blank lines are ignored, and whitespace before and after a  token  or  value  is
       ignored,  although a value can contain whitespace within.  Lines which begin with a # or ;
       are considered comments and ignored.

       If a line begins with a single -, any attempts to set the value that fail will be ignored.

NOTES

       As the /etc/sysctl.conf file is used to override default kernel parameter values,  only  a
       small  number  of  parameters  is  predefined  in the file.  Use /sbin/sysctl -a or follow
       sysctl(8) to list all possible parameters. The description of individual parameters can be
       found in the kernel documentation.

EXAMPLE

              # sysctl.conf sample
              #
                kernel.domainname = example.com
              ; this one has a space which will be written to the sysctl!
                kernel.modprobe = /sbin/mod probe
