So you take the list of 30-40 "installed by default" userids, add a list of 100
or so common first names/last names, prepend/append a single letter (i.e.
starting with "john" and "smith", also try "jsmith" and "johns").  Then try
each of those with a list of common passwords.  If you're *really* 31337, you
apply the SSH timing hole to possibly identify valid userids - but it really
isn't needed because it's just as cheap to just try all 40,000 combinations of
userid/password (remember, you're doing this from somebody else's compromised
system).
