I've been reading about TCP Wrapper here and wondering how to test it if none of the executable daemon compiled/supported by TCP Wrapper.
https://www.cyberciti.biz/faq/tcp-wrappers-hosts-allow-deny-tutorial/
Initially, I was planning to test it with ssh.
It turn's out it was not supported. Same problem with nc.
tc@box:~$ ldd /usr/bin/nc | grep wr
tc@box:~$ ldd /usr/local/sbin/sshd | grep wr
tc@box:~$
Please let me know if there is easier solution to test host-based firewall.

TCP wrappers were removed from OpenSSH years ago. It appears less and less software is continuing to use TCP wrappers as better approaches are available. Your distribution should have come with a modern host-based firewall already installed, possiblyfirewalldoriptables.

firewalld or iptables.– GracefulRestart
