Well, I read here that it "accepts your passphrase" - how does this work, 
then? If you use keys, you need no passphrase - if you use passwords,
it won't do the commands in ~/.ssh/authorized_keys2.

And to turn off the agent as Cameron Simpson told previously, it's sufficient
to clear the environment variable SSH_AUTH_SOCK (at least on UNIX).

Hope that helps!
