Fine. So tell someone working on A/UX to get in touch with me.

Somehow certain people have formed the mistaken impression that I have
been treating large sites differently from small sites. As I have tried
to explain, I do *not* see a fine line between the administrator of one
machine and the manager of a network of ten thousand machines. I have
not made and will not make a policy of sending break code to anyone who
asks---exactly *because* wide distribution of the code will eventually
reach the ``bad guys'', will affect practically every UNIX machine on
the Internet, and won't be traceable. So (as Dave Hayes can assure you)
I haven't been sending code to people merely because they manage a
``large enough'' network.

Would you like to reevaluate my ``irrational'' position, now that you
have some idea of what my position actually is?

If a vendor doesn't react by October 1992, its systems will be open to
attack by any novice with rn and cc. Don't get the idea that I trust
vendors to fix problems; I just want to give the more sensible ones a
chance to clean up their act. I suspect that at least some will react.

I'd like to request once again that people read my articles before
spouting off about the proper distribution of security information. I
*have* posted fixes, not just complained about these holes. I have *not*
indicated that large sites are getting any special treatment, nor have I
been giving them any special treatment. I *have* set a date for
distributing code---a date far enough in the future that any concerned
vendor can fix its systems.

This may not be the optimal policy for handling a security hole, but
it's the best policy I've come up with, and I'm not going to listen to
complaints from people who can neither formulate a consistent
alternative policy nor think through its effects. The intelligent man
does not criticize what he cannot improve.
