.SH "NAME"
ipsec-_stackmanager \- internal script to bring up kernel components for Libreswan
.SH "SYNOPSIS"
.HP \w'\fBipsec\ _stackmanager\fR\ 'u
\fBipsec _stackmanager\fR {start | stop}
.SH "DESCRIPTION"
.PP
\fBipsec _stackmanager\fR
is called from within the init sub\-system (systemd, upstart, sysv initscripts) to bring up the Libreswan kernel component as configured via the
\fIprotostack=\fR
option in the
\fIipsec\&.conf\fR
configuration file\&.
.PP
This involves loading and optionally unloading of the required kernel modules\&. Because the Linux kernel cannot autodetect most crypto related drivers on\-demand, _stackmanager handles loading the modules for the specific IPsec stack\&.

.SH "HISTORY"
.PP
This script was introduced in Libreswan\&. On the older Openswan systems, this functionality was split over various script files such as ipsec _startnetkey, ipsec _startklips, ipsec _realsetup and ipsec setup\&.
