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.
FILES
- /etc/sysctl.conf
- Initial settings for sysctl(8).
EXAMPLES
To disable coredumps, you may use a configuration like:
# Disable coredumps. kern.coredump=0
SEE ALSO
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.
