You need to be running a OpenBSD 4.4-current snapshot to get this or possibly even compiling OpenSSH-5.1 from source.
But edit per user ssh config or /etc/ssh/ssh_config and add this line:
VisualHostKey yes
Then ssh to some remote box or even locally (you should see something like below):
I though it was pretty neat. 
I wasn’t able to get WPA/WPA2 to work in OpenBSD 4.3-current in April of this year (support for WPA was added in mid April). So I thought it was too early and might be a little buggy still, and would wait until after OpenBSD 4.3 was released.
I have been thinking more about wireless security lately and thought I would give it another try (since I was using WEP). Upon installing and getting to the same point and failing like I did in April. I thought I would start messing with the options for ifconfig. The offending option was ‘wpaakms’ which defaults to’psk,802.1x’ and seems that it uses 802.1x (which uses an external server for authentication) by default. So after setting ‘wpaakms psk’ fixed all my problems, because I just want to enter a password/pass phrase.
If you have a supported card and are running a current snapshot follow the below example that I used for my ral supported card::
# /etc/hostname.ral0
inet 10.0.2.1 255.255.255.0 NONE media autoselect \
mode 11g nwid obsd-wpa wpa wpapsk $(wpa-psk obsd-wpa super_secret_password_here) \
wpaakms psk mediaopt hostap
# ifconfig ral

You will also need to setup dhcpd, and PF to get working, but after that all you need to do with your device is scan and enter ’super_secret_password_here’ and you’ll be surfing in no time at all.

The meeting is on a Wednesday (in 2 days) from 6PM – 9PM at the downtown Kansas City Public Library in meeting room 310 (upstairs on the third floor). Hopefully this new room will be more comfortable than the Plaza Library. Topics/discussions are open.
It was funny, I seen a couple KCLUGers walking to the library as I was pulling into the parking garage. I was thinking they were coming to the KCBUG meeting. Well it turns out the Commodore 64 User Group was having a meeting (or so they thought). In the end, we let them have the meeting room, while Noah and I found another place. Notes:
Please watch this blog and the mailing for updates to meeting location change. See you next month.
The meeting will be at the original meeting place, and also the same time 6PM – 8:45PM. I am not yet sure what topic(s) I will speak about if at all. This day being a special one for some members the turn out will probably be lower, but I will still come!
It is official, meeting is 2008-01-09 at 6PM-8:45PM at the Plaza Library. Parking is near (just south of the library about 500ft or so) and is free. Read the first link for more information.
I would like to have a meeting on the 9th of January. I haven’t come up with a meeting location and am open to suggestion (place with wifi, preferable) for the first one. If no suggestion are made I will setup (a week before the meeting date) a place near the plaza +/- 5 miles. I was thinking about discussing possible future meeting locations and do a little demo of yaifo.
KCBUG.org is now up and running.
First, we’d like to welcome you. Right now we’re only two members strong, but we’re hoping you’ll join as well. Click the “Find Us” link above to see a list of ways to get in touch.
Membership is free, there are no requirements other than a curiosity about what BSD is and how to make it work for you.
