ikedInternet Key Exchange version 2 (IKEv2) daemon

iked [-6dnSTtv] [-D macro=value] [-f file]

iked is an Internet Key Exchange (IKEv2) daemon which performs mutual authentication and which establishes and maintains IPsec flows and security associations (SAs) between the two peers.

The IKEv2 protocol is defined in RFC 5996, which combines and updates the previous standards: ISAKMP/Oakley (RFC 2408), IKE (RFC 2409), and the Internet DOI (RFC 2407). iked only supports the IKEv2 protocol; support for ISAKMP/Oakley and IKEv1 is provided by isakmpd(8).

iked supports mutual authentication using RSA public keys and X.509 certificates. See the FILES section below and PKI AND CERTIFICATE AUTHORITY COMMANDS in ikectl(8) for more information about creating and maintaining the public key infrastructure.

The options are as follows:

Disable automatic blocking of IPv6 traffic. By default, iked blocks any IPv6 traffic unless a flow for this address family has been negotiated. This option is used to prevent VPN traffic leakages on dual stack hosts.
Define macro to be set to value on the command line. Overrides the definition of macro in the configuration file.
Do not daemonize and log to .
Use file as the configuration file, instead of the default /etc/iked.conf.
Configtest mode. Only check the configuration file for validity.
Start iked in passive mode. See the set passive option in iked.conf(5) for more information.
Disable NAT-Traversal and do not propose NAT-Traversal support to the peers.
Enforce NAT-Traversal and only listen to NAT-Traversal messages. This option is only recommended for testing; the default is to negotiate NAT-Traversal with the peers.
Produce more verbose output.

The default iked configuration file.
The directory where CA certificates are kept.
The directory where IKE certificates are kept, both the local certificate(s) and those of the peers, if a choice to have them kept permanently has been made.
The directory where CRLs are kept.
The directory where local private keys used for public key authentication are kept. The file local.key is used to store the local private key.
The directory in which trusted public keys are kept. The keys must be named in the fashion described above.
The default iked control socket.

The iked program first appeared in OpenBSD 4.8.

The iked program was written by Reyk Floeter ⟨⟩.

iked is not yet finished and is missing some important security features. It should not yet be used in production networks.
