SYSCTL.CONF(5)

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.

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
