NAME
sysctl.conf —
sysctl configuration
file
SYNOPSIS
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.
