NAME

sysctl.conf - sysctl configuration file

SYNOPSIS

sysctl.conf

DESCRIPTION

The sysctl.conf file defines the sysctl(7) kernel state tunables that can be set at boot time using sysctl(8) (using the -f switch) via the /etc/rc.d/sysctl startup script.

The state to be set is described using a ``Management Information Base'' (``MIB'') style name. The MIB and value must be separated by `=' with no whitespace, for example:

name=value

Blank lines, lines with just name, and comments (beginning with `#') are ignored. Line continuations using backslash `\' are permitted. Only integral and string values can be set.

FILES

/etc/sysctl.conf
The file sysctl.conf resides in /etc.

EXAMPLES

The following is an example /etc/sysctl.conf file:

# Change max open files
kern.maxfiles=1792
        

# Run Veriexec in IDS mode kern.veriexec.strict=1
