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
