.B charon
.br
Options for the charon IKE daemon.

.RB "" "Note" ":"
Many of the options in this section also apply to
.RB "" "charon\-cmd" ""
and
other
.RB "" "charon" ""
derivatives.  Just use their respective name (e.g.
.RB "" "charon\-cmd" ""
instead of
.RB "" "charon" ")."
For many options defaults can be defined
in the
.RB "" "libstrongswan" ""
section.

.TP
.BR charon.accept_unencrypted_mainmode_messages " [no]"
Accept unencrypted ID and HASH payloads in IKEv1 Main Mode.

Some implementations send the third Main Mode message unencrypted, probably to
find the PSKs for the specified ID for authentication. This is very similar to
Aggressive Mode, and has the same security implications: A passive attacker can
sniff the negotiated Identity, and start brute forcing the PSK using the HASH
payload.

It is recommended to keep this option to no, unless you know exactly what the
implications are and require compatibility to such devices (for example, some
SonicWall boxes).

.TP
.BR charon.block_threshold " [5]"
Maximum number of half\-open IKE_SAs for a single peer IP.

(stroke) or
.RB "" "/etc/swanctl/x509crl" ""
(vici), respectively.

Delete CHILD_SAs right after they got successfully rekeyed (IKEv1 only). Reduces
the number of stale CHILD_SAs in scenarios with a lot of rekeyings. However,
this might cause problems with implementations that continue to use rekeyed SAs
until they expire.

.TP
.BR charon.delete_rekeyed_delay " [5]"
Delay in seconds until inbound IPsec SAs are deleted after rekeyings (IKEv2
only). To process delayed packets the inbound part of a CHILD_SA is kept
installed up to the configured number of seconds after it got replaced during a
rekeying. If set to 0 the CHILD_SA will be kept installed until it expires (if
no lifetime is set it will be destroyed immediately).

.TP
.BR charon.dh_exponent_ansi_x9_42 " [yes]"

strength.

passed to
.RB "" "strftime" "(3)."

Whether to follow IKEv2 redirects (RFC 5685).

.TP
.BR charon.fragment_size " [1280]"
Maximum size (complete IP datagram size in bytes) of a sent IKE fragment when
using proprietary IKEv1 or standardized IKEv2 fragmentation, defaults to 1280

If enabled responders are allowed to use IKEv1 Aggressive Mode with pre\-shared
keys, which is discouraged due to security concerns (offline attacks on the
openly transmitted hash of the PSK).

.TP
.BR charon.ignore_acquire_ts " [no]"
If this is disabled the traffic selectors from the kernel's acquire events,
which are derived from the triggering packet, are prepended to the traffic
selectors from the configuration for IKEv2 connection. By enabling this, such
specific traffic selectors will be ignored and only the ones in the config will
be sent. This always happens for IKEv1 connections as the protocol only supports
one set of traffic selectors per CHILD_SA.

If enabled, the list of plugins to load is determined via the value of the
.RI "" "charon.plugins.<name>.load" ""
options.  In addition to a simple boolean flag that
option may take an integer value indicating the priority of a plugin, which
would influence the order of a plugin in the plugin list (the default is 1). If
two plugins have the same priority their order in the default plugin list is
preserved. Enabled plugins not found in that list are ordered alphabetically
before other plugins with the same priority.

.TP
.BR charon.make_before_break " [no]"
Initiate IKEv2 reauthentication with a make\-before\-break instead of a
break\-before\-make scheme. Make\-before\-break uses overlapping IKE and CHILD_SA
during reauthentication by first recreating all new SAs before deleting the old
ones. This behavior can be beneficial to avoid connectivity gaps during
reauthentication, but requires support for overlapping SAs by the peer.
strongSwan can handle such overlapping SAs since version 5.3.0.

.TP
.BR charon.plugins.addrblock.strict " [yes]"
If set to yes, a subject certificate without an addrblock extension is rejected
if the issuer certificate has such an addrblock extension. If set to no, subject
certificates issued without the addrblock extension are accepted without any
traffic selector checks and no policy is enforced by the plugin.

.TP

or the numeric identifier of the attribute
type. The assigned value can be an IPv4/IPv6 address, a subnet in CIDR notation
or an arbitrary value depending on the attribute type.  For some attribute types

server runs on the same host as strongSwan, and the DHCP daemon does not listen
on the loopback interface.  In that case the server cannot be reached via

this option to yes and configuring the local broadcast address (e.g.

to circumvent that problem.

.TP

bytes of Netlink messages can be received on a Netlink socket. The default value

.B charon.plugins.kernel-netlink.spdh_thresh
.br
XFRM policy hashing threshold configuration for IPv4 and IPv6.

The section defines hashing thresholds to configure in the kernel during daemon
startup. Each address family takes a threshold for the local subnet of an IPsec
policy (src in out\-policies, dst in in\- and forward\-policies) and the remote
subnet (dst in out\-policies, src in in\- and forward\-policies).

If the subnet has more or equal net bits than the threshold, the first threshold
bits are used to calculate a hash to lookup the policy.

Policy hashing thresholds are not supported before Linux 3.18 and might conflict
with socket policies before Linux 4.8.

policy. The value gets written to /proc/sys/net/core/xfrm_acq_expires.
Indirectly controls the delay between XFRM acquire messages triggered by the
kernel for a trap policy. The same value is used as timeout for SPIs allocated
by the kernel. The default value equals the total   retransmission timeout for
IKE messages, see IKEv2 RETRANSMISSION in
.RB "" "strongswan.conf" "(5)."


.TP
.BR charon.plugins.kernel-pfkey.events_buffer_size " [0]"
