Well, that's why I'm asking.

Yes, I have heard of that.

But, are you actually using it? Do you need to?

There are real downsides to carrying unmaintained code forward.

Someone put forth the possibility of developing and maintaining a
maintaining a modern library implementing the same config files but with a
an updated codebase and better API, but no one has actually volunteered to
do that work. If you'd like to be that person, awesome.

Yes, and know for sure people use that -- I do, for example. But I use it to
manipulate IP tables, which is more secure and less fragile than the
hosts.deny action (it's always a bit scary when configuration files are
edited by a program!). Because it is actively maintained upstream, there's
even support for new things like firewalld.

On the other hand, people using unmaintained solutions like DenyHosts would
have to migrate.
