LEARN ABOUT FREEBSD
sysctl.conf
SYSCTL.CONF(5) BSD File Formats Manual SYSCTL.CONF(5)
NAME
sysctl.conf -- kernel state defaults
DESCRIPTION
The /etc/sysctl.conf file is read in when the system goes into multi-user mode to set default settings for the kernel. The /etc/sysctl.conf
is in the format of the sysctl(8) command, i.e.
sysctl_mib=value
Comments are denoted by a ``#'' at the beginning of a line. Comments can also exist at the end of a line, as seen in the EXAMPLES section,
below.
FILES
/etc/sysctl.conf Initial settings for sysctl(8).
EXAMPLES
To turn off logging of programs that exit due to fatal signals you may use a configuration like
# Configure logging.
kern.logsigexit=0 # Do not log fatal signal exits (e.g. sig 11)
SEE ALSO
rc.conf(5), rc(8), sysctl(8)
HISTORY
The sysctl.conf file appeared in FreeBSD 4.0.
BUGS
If loadable kernel modules are used to introduce additional kernel functionality and sysctls to manage that functionality, sysctl.conf may be
processed too early in the boot process to set those sysctls. For example, sysctls to manage the linux emulator cannot be set in sysctl.conf
if the linux emulator is loaded as a module rather than compiled into the kernel.
