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

       /etc/sysctl.d/*.conf
