In passive mode no packets are sent to peers and no connections are initiated by .Xr iked 8 . .It Cm couple Load the negotiated security associations (SAs) and flows into the kernel. .It Cm decouple Unload the negotiated SAs and flows from the kernel. This mode is only useful for testing and debugging. .It Cm load Ar filename Reload the configuration from the specified file. .It Cm log brief Disable verbose logging. .It Cm log verbose Enable verbose logging. .It Cm monitor Monitor internal messages of the .Xr iked 8 subsystems. .It Cm reload Reload the configuration from the default configuration file. .It Cm reset all Reset the the running state. .It Cm reset ca Reset the X.509 CA and certificate state. .It Cm reset policy Flush the configured policies. .It Cm reset sa Flush the running SAs. .It Cm reset user Flush the local user database. .El .Sh PKI AND CERTIFICATE AUTHORITY COMMANDS In order to use public key based authentication with IKEv2, a public key infrastructure (PKI) has to be set up to create and sign the peer certificates. .Nm includes commands to simplify maintenance of the PKI and to set up a simple certificate authority (CA) for .Xr iked 8 and its peers. .Pp The following commands are available to control the CA: .Bl -tag -width Ds .It Xo .Cm ca Ar name Cm create .Op Cm password Ar password .Xc Create a new certificate authority with the specified .Ar name . The command will prompt for a CA password unless it is specified with the optional .Ar password argument. The password will be saved in a protected file .Pa ikeca.passwd in the CA directory and used for subsequent commands. .It Cm ca Ar name Cm delete Delete the certificate authority with the specified .Ar name . .It Xo .Cm ca Ar name Cm export .Op Cm peer Ar peer .Op Cm password Ar password .Xc Export the certificate authority with the specified .Ar name into the current directory for transport to other systems. This command will create a compressed tarball called .Pa ca.tgz in the local directory and optionally .Pa ca.zip if the .Sq zip tool is installed. The optional .Ar peer argument can be used to specify the address or FQDN of the local gateway which will be written into a text file .Pa peer.txt and included in the archives. .It Xo .Cm ca Ar name .Cm install Op Ar path .Xc Install the certificate and Certificate Revocation List (CRL) for CA .Ar name as the currently active CA or into the specified .Ar path . .It Xo .Cm ca Ar name Cm certificate Ar host .Cm create .Op Ic server \*(Ba client .Xc Create a private key and certificate for .Ar host and sign then with the key of certificate authority with the specified .Ar name . .Pp The certificate will be valid for client and server authentication by default by setting both flags as the extended key usage in the certificate; this can be restricted using the optional .Ic server or .Ic client argument. .It Xo .Cm ca Ar name Cm certificate Ar host .Cm delete .Xc Deletes the private key and and certificates associated with .Ar host . .It Xo .Cm ca Ar name Cm certificate Ar host .Cm export .Op Cm peer Ar peer .Op Cm password Ar password .Xc Export key files for .Ar host of the certificate authority with the specified .Ar name into the current directory for transport to other systems. This command will create a compressed tarball .Pa host.tgz in the local directory and optionally .Pa host.zip if the .Sq zip tool is installed. The optional .Ar peer argument can be used to specify the address or FQDN of the local gateway which will be written into a text file .Pa peer.txt and included in the archives. .It Xo .Cm ca Ar name Cm certificate Ar host .Cm install Op Ar path .Xc Install the private and public key for .Ar host into the active configuration or specified .Ar path . .It Xo .Cm ca Ar name Cm certificate Ar host .Cm revoke .Xc Revoke the certificate specified by .Ar host and generate a new Certificate Revocation List (CRL). .It Xo .Cm show Cm ca Ar name Cm certificates .Op Ar host .Xc Display a listing of certificates associated with CA .Ar name or display certificate details if .Ar host is specified. .It Xo .Cm ca Ar name Cm key Ar host .Cm create .Xc Create a private key for .Ar host if one does not already exist. .It Xo .Cm ca Ar name Cm key Ar host .Cm install Op Ar path .Xc Install the private and public keys for .Ar host into the active configuration or specified .Ar path . .It Xo .Cm ca Ar name Cm key Ar host .Cm delete .Xc Delete the private key for .Ar host . .It Xo .Cm ca Ar name Cm key Ar host .Cm import .Ar file .Xc Source the private key for .Ar host from the named .Ar file . .El .Sh FILES .Bl -tag -width "/var/run/iked.sockXX" -compact .It /etc/iked/ Active configuration. .It /etc/ssl/ Directory to store the CA files. .It /usr/share/iked If this optional directory exists, .Nm will include the contents with the .Cm ca export commands. .It /var/run/iked.sock default .Ux Ns -domain socket used for communication with .Xr iked 8 .El .Sh EXAMPLES First create a new certificate authority: .Bd -literal -offset indent # ikectl ca vpn create .Ed .Pp Now create the certificates for the VPN peers. The specified hostname, either IP address or FQDN, will be saved in the signed certificate and has to match the IKEv2 identity, or .Ar srcid , of the peers: .Bd -literal -offset indent # ikectl ca vpn certificate 10.1.2.3 create # ikectl ca vpn certificate 10.2.3.4 create # ikectl ca vpn certificate 10.3.4.5 create .Ed .Pp It is possible that the host that was used to create the CA is also one of the VPN peers. In this case you can install the peer and CA certificates locally: .Bd -literal -offset indent # ikectl ca vpn install # ikectl ca vpn certificate 10.1.2.3 install .Ed .Pp Now export the individual host key, the certificate and the CA certificate to each other peer. First run the .Ic export command to create tarballs that include the required files: .Bd -literal -offset indent # ikectl ca vpn certificate 10.2.3.4 export # ikectl ca vpn certificate 10.3.4.5 export .Ed .Pp These commands will produce two tarballs .Em 10.1.2.3.tgz and .Em 10.4.5.6.tgz . Copy these tarballs over to the appropriate peers and extract them to the .Pa /etc/iked/ directory: .Bd -literal -offset indent 10.2.3.4# tar -C /etc/iked -xzpf 10.2.3.4.tgz 10.3.4.5# tar -C /etc/iked -xzpf 10.3.4.5.tgz .Ed .Pp .Nm will also create .Sq zip archives 10.2.3.4.zip and 10.3.4.5.zip in addition to the tarballs if the zip tool is found in .Pa /usr/local/bin/zip . These archives can be exported to peers running Windows and will include the certificates in a format that is supported by the OS. The zip tool can be installed from the .Ox packages or ports collection before running the .Ic export commands, see .Xr packages 7 for more information. For example: .Bd -literal -offset indent # pkg_add zip .Ed .Sh SEE ALSO .Xr packages 7 , .Xr iked 8 , .Xr ssl 8 .Sh HISTORY The .Nm program first appeared in .Ox 4.8 . .Sh AUTHORS The .Nm program was written by .An Reyk Floeter Aq reyk@vantronix.net and .An Jonathan Gray Aq jsg@vantronix.net . .Sh CAVEATS For ease of use, the .Ic ca commands maintain all peers' private keys on the CA machine. In contrast to a .Sq real CA, it does not support signing of public keys that have been imported from peers that do not want to expose their private keys to the CA.
