ikectl errors

Hi!

I'm trying to set up iked on machine A, to create a tunnel between machines
A and B. ikectl produces errors when creating a certificate with my "test"
ca, and I have failed to understans why:

# ikectl ca test certificate 192.168.1.1 create
Generating RSA private key, 2048 bit long modulus

e is 65537 (0x10001)
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blankFor some fields
there will be a default value,
If you enter '.', the field will be left blank.

Country Name (2 letter code) [DE]:
State or Province Name (full name) [Lower Saxony]:
Locality Name (eg, city) [Hanover]:
Organization Name (eg, company) [OpenBSD]:
Organizational Unit Name (eg, section) [iked]:
Common Name (eg, fully qualified host name) [192.168.1.1]:

The machine is i386 running 6.2-stable.

I assume I'm doing something wrong, or have missed something in previous
steps (I followed the example steps from the ikectl man page). Any tips on
where to start digging/understanding/learning/fixing would be highly
appreciated.
