By finding a vulnerability in TCP wrappers, should one exist, or even in the
TCP stack of whatever operating system you're using.

Using a stateful firewall means the attacker doesn't even get that far.

And that's obviously not as secure as I like it.

It started as your example, I just carried it along.

I wasn't addressing anything to do with the Debian default configuration of
tcpd. I'm happy with how it is now, and don't care enough to fill the list
with more crap about it.

What I was addressing is your assertion that you can fully protect a machine
from any attack using IP-based access lists with TCP wrappers instead of a
stateful firewall. That's a little piece of misinformation that everyone
can do without.

You're right, I don't know you. But I've read several posts of yours, and
like I said, you seem to demonstrate a fundamental lack of understanding on
the topic you're talking about.
