       Auto manipulates automatically-keyed Libreswan IPsec connections, setting them up and
       shutting them down based on the information in the IPsec configuration file. In the normal
       usage, connection is the name of a connection specification in the configuration file;
       operation is --add, --delete, --replace, --start, --up, --down, --route, --unroute, or
       --ondemand. The --ready, --rereadsecrets, and --status operations do not take a connection
       name.  Auto generates suitable commands and feeds them to a shell for execution.

       The --add operation adds a connection specification to the internal database within pluto;
       it will fail if pluto already has a specification by that name. The --delete operation
       deletes a connection specification from pluto's internal database (also tearing down any
       connections based on it); The --replace operation is equivalent to --delete (if there is
       already a loaded connection by the given name) followed by --add, and is a convenience for
       updating pluto's internal specification to match an external one. (Note that a
       --rereadsecrets may also be needed.) The --start operation is equivalent to running first
       with --add and then with --up, causing same effect as connection configuration option

       The --up operation asks pluto to establish a connection based on an entry in its internal
       database. The --down operation tells pluto to tear down such a connection.

       Normally, pluto establishes a route to the destination specified for a connection as part
       of the --up operation. However, the route (for KLIPS) and packet capture (KLIPS and
       NETKEY) can be established with the --route 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).

       Normally, pluto's route (KLIPS) or packet capture (NETKEY) to a destination remains in
       place when a --down 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 --unroute operation (and is implicitly removed by --delete).

       The --ondemand operation is equivalent to running first with --add and then with --route,
       causing same effect as connection configuration option auto=ondemand.

       The --ready operation tells pluto to listen for connection-setup requests from other
       hosts. Doing an --up operation before doing --ready 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.

       The --status operation asks pluto for current connection status. The output format is
       ad-hoc and likely to change.

       The --rereadsecrets operation tells pluto to re-read the /etc/ipsec.secrets secret-keys
       file, which it normally reads only at startup time. (This is currently a synonym for
       --ready, but that may change.)

       The --fetchcrls operation reads all certificate revocation list (CRL) entries of loaded
       certificates and tries to fetch updates for these from the CRL servers.

       The --rereadall operation is equivalent to the execution of --rereadsecrets (in the past
       there were other kinds of reread operations)

       The --listpubkeys operation lists all RSA public keys either received from peers via the
       IKE protocol embedded in authenticated certificate payloads or loaded locally using the
       rightcert / leftcert or rightr- sasigkey / leftrsasigkey parameters in ipsec.conf(5).

       The --listcerts operation lists all X.509 certificates loaded locally using the rightcert
       and leftcert parameters in ipsec.conf(5). To see all certificates in the NSS database, use
       certutil -d /var/lib/ipsec/nss -L.

       The --checkpubkeys operation lists all loaded X.509 certificates that are about to expire
       or have expired.

       The --listcacerts operation lists all X.509 CA certificates contained in the NSS database.

       The --listcrls operation lists all Certificate Revocation Lists (CRLs) either loaded
       locally from the /etc/ipsec.d/crls directory or fetched dynamically from an HTTP or LDAP

       The --listall operation is equivalent to the execution of --listpubkeys, --listcerts,
       --listcacerts, --listcrls.

       The --purgeocsp operation displays --listall and purges the NSS OCSP cache.

       The --showonly option causes auto to show the commands it would run, on standard output,
       and not run them.

       The --asynchronous option, applicable only to the up operation, tells pluto 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.

       The --verbose option instructs auto to pass through all output from ipsec_whack(8),
       including log output that is normally filtered out as uninteresting.

       The --config option specifies a non-standard location for the IPsec configuration file
       (default /etc/ipsec.conf).

       See ipsec.conf(5) for details of the configuration file.

           /var/lib/ipsec/nss            X.509 and Opportunistic Encryption files
           /var/run/pluto/pluto.ctl Pluto command socket

       Although an --up operation does connection setup on both ends, --down tears only one end
       of the connection down (although the orphaned end will eventually time out).

       There is no support for passthrough connections.

       A connection description that uses %defaultroute for one of its nexthop parameters but not
       the other may be falsely rejected as erroneous in some circumstances.

       The exit status of --showonly 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.)
