command
.SH DESCRIPTION
.I Setup
controls the FreeS/WAN IPsec subsystem,
including both the Klips kernel code and the Pluto key-negotiation daemon.
(It is a synonym for the ``rc'' script for the subsystem;
the system runs the equivalent of
.B "ipsec setup start"
at boot time,
and
.B "ipsec setup stop"
at shutdown time, more or less.)
.PP
The action taken depends on the specific
.IR command ,
and on the contents of the
.B config
.B setup
section of the
IPsec configuration file (\c
.IR /etc/ipsec.conf ,
see
.IR ipsec.conf (5)).
Current
.IR command s
are:
.TP 10
.B start
start Klips and Pluto,
including setting up Klips to do crypto operations on the 
interface(s) specified in the configuration file,
and (if the configuration file so specifies)
setting up manually-keyed connections and/or
asking Pluto to negotiate automatically-keyed connections
to other security gateways
.TP
.B stop
shut down Klips and Pluto,
including tearing down all existing crypto connections
.TP
.B restart
equivalent to
.B stop
followed by
.B start
.TP
.B status
The
.B stop
operation tries to clean up properly even if assorted accidents
have occurred,
e.g. Pluto having died without removing its lock file.
If
.B stop
discovers that the subsystem is (supposedly) not running,
it will complain,
but will do its cleanup anyway before exiting with status 1.
.PP
Although a number of configuration-file parameters influence
.IR setup 's
operations, the key one is the
.B interfaces
parameter, which must be right or chaos will ensue.
.PP
The
.B \-\-show
and
.B \-\-showonly
options cause
.I setup
to display the shell commands that it would execute.
.B \-\-showonly
suppresses their execution.
Only
.BR start ,
.BR stop ,
and
.B restart
commands recognize these flags.
