SYSCTL.CONF(5) BSD File Formats Manual SYSCTL.CONF(5)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.

# Change max open files

# Run Veriexec in IDS mode
