Hi,

Don't think this is the solution. Part of the problem is that some of
the functionality is just obsolete in todays world. Trusting IDENT and
DNS for access control maybe made sense in the 90ies. It certainly
doesn't today, and IMO lennart is correct in classifying this as
"security theater".

I'd say moving the functionality which still makes sense (ip range based
checks) to the firewall is more useful. Guess it shouldn't be that hard
to write a utility translating /etc/hosts.{allow,deny} into iptables
rules, or add support for that to firewalld.
Does tcpwrap support ipv6 btw?
cheers,
Gerd
