Years ago, when the only 'puter we had at work was a PDP-11, I asked Austin, the chief honcho, what's the 'root' password. (OK, I was naive, in my 20's).
He replied "It's a complex key sequence".
A few years later he told me the real password.
Pretty good! Years later I tried to put Finnish words into Linux passwords - with umlauted characters - but The Penguin - ubuntu - (oddly, considering it's origin) does't like that. Now, I have to scan the Finnish dictionary for words like 'KYVYKKYYS' (capability) which really'll fuck 'john-the-ripper'. No, I don't use that one anymore.
