IKED(8) BSD System Manager's Manual IKED(8)NAMEiked — Internet Key Exchange protocol daemon
SYNOPSISiked [-46hvFV] [-f configfile] [-l logfile] [-p port] [-I peer-address]
[-S selector-index] [-d] [-D level] [-P outfile]
DESCRIPTIONiked is a key management daemon, which supports the Internet Key Exchange
(IKE) protocol version 1 (RFC2409) and version 2 (RFC4306). It is driven
by upcalls from the kernel via the PF_KEYv2 interface or by negotiation
requests from remote peers, and manages IPsec SAs according to
racoon2.conf.
The following options are available:
-4 Use IPv4 addresses only for local sockets.
-6 Use IPv6 addresses only for local sockets.
-d Increase the debugging level. This flag may occur multiple
times.
-f configfile
Read configurations from the specified file.
-I peer-address
Immediately initiate to the peer specified.
-S selector_index
Immediately initiate using the selector specified.
-h Show simple help messages.
-l logfile
Output log to logfile instead of syslog.
-p portnum
Specify default port number for IKE sockets.
-v Output log to stdout in addition to syslog.
-D num Set debug flag.
-F Run in the foreground. iked does not detach itself from the ter‐
minal and does not become a daemon. Logs are output to the
stderr.
-P outfile
Record unencrypted IKE communication packets to the file. This
option is available only if iked was compiled with --enable-pcap
configuration option.
-V Show the version.
Upon receiving SIGINT or SIGTERM, iked shuts down IKEv2 IKE_SAs with peer
nodes by sending Informational exchange with Delete payload, deletes rel‐
evant IPsec SAs, and then exits. Upon receiving SIGHUP, iked similarly
shuts down IKEv2 IKE_SAs and deletes relevant IPsec SAs, then reloads the
configuration file.
IPsec policies are managed by spmd(8), thus it must be started before
iked. When spmd(8) restarts, iked needs to be reloaded to reconnect with
it.

ACKNOWLEDGEMENTS
Part of the codes are derived from ipsec-tools racoon daemon, which was
derived from KAME racoon daemon.
BUGS
"default" clause of configuration file is used for two purposes: to pro‐
vide default values for individual field for other sections of configura‐
tion, and to specify default kmp configuration when the responder
received a message from unknown peer. In latter case, when "default"
clause lacks some necessary fields, error message may be cryptic, since
it is not checked by configuration check routine of iked. (Probably it
will result in "no proposal chosen".)
On FreeBSD/NetBSD, when IPsec SA expires by IPsec SA lifetime, kernel
does not notify iked about the sa expiration. To remedy this, iked main‐
tains its own expiration timer for each IPsec SA. Since the iked can't
know how much bytes used for the SA, lifetime_bytes in the configuration
are ignored for now.
SA bundles (e.g. AH+ESP) does not conform to protocol spec.
After rekeying IKE_SA, iked may spit some warning messages, if the rekey
negotiation or delete request was started from both ends at once.
