.::: How to Install PowerDNS and Poweradmin on CentOS 7 :::.

PowerDNS (pdns) is an open source DNS server written in C++ and released under GPL License. It has become a good alternative for the traditional DNS server Bind, designed with better performance and low memory requirements. PowerDNS provides two products, the Authoritative server, and the Recursor. The PowerDNS Authoritative server can be configured through the different backend, including the plain Bind zone files, RDBMS such as MySQL, PostgreSQL, SQLite3 or LDAP.
1. Disable /allow firewall, selinux and add hosts
[root@powerdns-teguht data]# systemctl stop firewalld
[root@powerdns-teguht data]# systemctl disable firewalld
rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service'
rm '/etc/systemd/system/basic.target.wants/firewalld.service'
[root@powerdns-teguht data]#

.::: Block a domain using RPZ on Bind DNS server on CentOS 7 Redhat 7 8 9 :::.

Domain Name Service Response Policy Zones (DNS RPZ) is a method that allows a nameserver administrator to overlay custom information on top of the global DNS to provide alternate responses to queries. It is currently implemented in the ISC BIND nameserver (9.8 or later). Another generic name for the DNS RPZ functionality is "DNS firewall".

1. Create zone for block using RPZ

[root@server-teguht ~]# cat /var/named/rpz.db
$TTL 1D
@    IN SOA ns1.example.com. root.example.com. (
                                        0      ;   serial
                                        1D     ;   refresh
                                        1H     ;   retry
                                        1W      ;  expire
                                        3H )     ; minimum

.::: Join Domain Active Directory on Centos 7 / Redhat 7, 8, 9 :::.

In Most of the Organizations users and groups are created and managed on Windows Active Directory.  We can integrate our RHEL 7 and CentOS 7 servers with AD(Active Directory) for authenticate purpose. In other words we can join our CentOS 7 and RHEL 7 Server on Windows Domain so that system admins can login to these Linux servers with AD credentials. While creating UNIX users on AD we can map these users to a specific group so that level of access is controlled centrally from AD

1. Install Package realmd, sssd, samba dan kerberos
[root@radius-teguht ~]# yum install sssd realmd oddjob oddjob-mkhomedir adcli samba-common samba-common-tools krb5-workstation openldap-clients policycoreutils-python -y

2. additional IP, domain, hostname on /etc/hosts , and /etc/resolv.conf
