I could not find any where the documentation the only best which I got was

My question is the following blog says to remove an IP from
/etc/hosts.deny which denyhost has blocked
you need to have a directory /usr/share/denyhosts/data
I do not find any such directory

Also when I tried to check  tcp wrapper configuration
as given here

tcpdchk -v
Cannot find your inetd.conf or tlid.conf file.
Please specify its location.

what does the above output mean?
How do I make sure denyhosts is doing its job?
