If you can do a 'netstat -a | grep [name of your machine here]', you
should see a line that looks something like this this:
novodny.22               potempkin.1021 32120      0  8760      0
        ^^- (might instead be ssh)
(where novodny is the server, and potempkin is my machine)

This shows that I'm connected to the ssh port (#22), and thus secured.
If you instead saw something like:

trotsky.login               potempkin.2044 8576      0  9112      0
that would mean you were not secured in any way.

Well, I've not really used F-Secure SSH for Windows (which it sounds
like you're using) that much, but ssh for for unix tells you that it's
reverting to an insecure connection.

netstat -a is a good bet...
