Replacing TCP Wrappers in RHEL 8 and 9

Solution Verified - Updated -

Issue

  • How do I set up access restrictions instead of TCP Wrappers?
  • Do /etc/hosts.allow and /etc/hosts.deny have any use in RHEL 8?
  • /etc/hosts.allow and /etc/hosts.deny are present on RHEL 8 Beta system. They are in the setup-2.12.2-1.el8.noarch RPM. What is the purpose now when tcp_wrappers is no longer available?
  • How can I use the deprecated and removed tcp_wrappers in RHEL 8?

Environment

  • Red Hat Enterprise Linux 8 and 9
  • firewalld
  • systemd
