<H2>DESCRIPTION</H2>
<I>Auto</I>
manipulates automatically-keyed FreeS/WAN IPsec connections,
setting them up and shutting them down
based on the information in the IPsec configuration file.
In the normal usage,
<I>connection</I>
is the name of a connection specification in the configuration file;
<I>operation</I>
is
<B>--add</B>,
<B>--delete</B>,
<B>--replace</B>,
<B>--up</B>,
<B>--down</B>,
<B>--route</B>,
or
<B>--unroute</B>.
The
<B>--ready</B>,
<B>--rereadsecrets</B>,
<B>--rereadgroups</B>,
and
<B>--status</B>
<I>operations</I>
do not take a connection name.
<I>Auto</I>
generates suitable
commands and feeds them to a shell for execution.
<P>
The
<B>--add</B>
operation adds a connection specification to the internal database
within
<I>pluto</I>;
it will fail if
<I>pluto</I>
already has a specification by that name.
The
<B>--delete</B>
operation deletes a connection specification from
<I>pluto</I>'s
internal database (also tearing down any connections based on it);
it will fail if the specification does not exist.
The
<B>--replace</B>
operation is equivalent to
<B>--delete</B>
(if there is already a specification by the given name)
followed by
<B>--add</B>,
and is a convenience for updating
<I>pluto</I>'s
internal specification to match an external one.
(Note that a
<B>--rereadsecrets</B>
may also be needed.)
The
<B>--rereadgroups</B>
operation causes any changes to the policy group files to take effect
(this is currently a synonym for
<B>--ready</B>,
but that may change).
None of the other operations alters the internal database.
<P>
The
<B>--up</B>
operation asks
<I>pluto</I>
to establish a connection based on an entry in its internal database.
The
<B>--down</B>
operation tells
<I>pluto</I>
to tear down such a connection.
<P>
Normally,
<I>pluto</I>
establishes a route to the destination specified for a connection as
part of the
<B>--up</B>
operation.
However, the route and only the route can be established with the
<B>--route</B>
operation.
Until and unless an actual connection is established,
this discards any packets sent there,
which may be preferable to having them sent elsewhere based on a more
general route (e.g., a default route).
<P>
Normally,
<I>pluto</I>'s
route to a destination remains in place when a
<B>--down</B>
operation is used to take the connection down
(or if connection setup, or later automatic rekeying, fails).
This permits establishing a new connection (perhaps using a
different specification; the route is altered as necessary)
without having a ``window'' in which packets might go elsewhere
based on a more general route.
Such a route can be removed using the
<B>--unroute</B>
operation
(and is implicitly removed by
<B>--delete</B>).
<P>
The
<B>--ready</B>
operation tells
<I>pluto</I>
to listen for connection-setup requests from other hosts.
Doing an
<B>--up</B>
operation before doing
<B>--ready</B>
on both ends is futile and will not work,
although this is now automated as part of IPsec startup and
should not normally be an issue.
<P>
The
<B>--status</B>
operation asks
<I>pluto</I>
for current connection status.
The output format is ad-hoc and likely to change.
<P>
The
<B>--rereadsecrets</B>
operation tells
<I>pluto</I>
to re-read the
<I>/etc/ipsec.secrets</I>
secret-keys file,
which it normally reads only at startup time.
(This is currently a synonym for
<B>--ready</B>,
but that may change.)
<P>
The
<B>--show</B>
option turns on the
<B>-x</B>
option of the shell used to execute the commands,
so each command is shown as it is executed.
<P>
The
<B>--showonly</B>
option causes
<I>auto</I>
to show the commands it would run, on standard output,
and not run them.
<P>
The
<B>--asynchronous</B>
option, applicable only to the
<B>up</B>
operation,
tells
<I>pluto</I>
to attempt to establish the connection,
but does not delay to report results.
This is especially useful to start multiple connections in parallel
when network links are slow.
<P>
The
<B>--verbose</B>
option instructs
<I>auto</I>
to pass through all output from
<I><A HREF="ipsec_whack.8.html">ipsec_whack</A></I>(8),
including log output that is normally filtered out as uninteresting.
<P>
The
<B>--config</B>
option specifies a non-standard location for the IPsec
configuration file (default
<I>/etc/ipsec.conf</I>).
<P>
See
<I><A HREF="ipsec.conf.5.html">ipsec.conf</A></I>(5)
for details of the configuration file.
Apart from the basic parameters which specify the endpoints and routing
of a connection (<B>left</B>
and
<B>right</B>,
plus possibly
<B>leftsubnet</B>,
<B>leftnexthop</B>,
<B>leftfirewall</B>,
their
<B>right</B>
equivalents,
and perhaps
<B>type</B>),
an
<I>auto</I>
connection almost certainly needs a
<B>keyingtries</B>
parameter (since the
<B>keyingtries</B>
default is poorly chosen).

<H2>BUGS</H2>
Although an
<B>--up</B>
operation does connection setup on both ends,
<B>--down</B>
tears only one end of the connection down
(although the orphaned end will eventually time out).
<P>
There is no support for
<B>passthrough</B>
connections.
<P>
A connection description which uses
<B>%defaultroute</B>
for one of its
<B>nexthop</B>
parameters but not the other may be falsely
rejected as erroneous in some circumstances.
<P>
The exit status of
<B>--showonly</B>
does not always reflect errors discovered during processing of the request.
(This is fine for human inspection, but not so good for use in scripts.)
