    Hello Everyone,

    I am a newbie in Linux and I really need a tutorial/help for doing this.

    I have CentOS 5.5 32 bits in Master/Slave Servers

    1. For Master Server:

    I want to speed Up Postfix Mail Server with PowerDNS like
    I do not know how to do it with PowerDNS.

    I mean, I want to have "caching-nameserver" with localhost recursion.
    But I want to deny recursion to external clients.

    2. Set up 2 servers master/slave with PowerDNS (With MySQL Backend) And Poweradmin
    with database replication with ssl encryption


    Can those tutorials "work" together to do it?

    3. iptables configuration

    3.1 I have iptables in Master/Slave Servers.

    How to configure iptables to work with MySQL database replication with ssl encryption?

    3.2. In order to allow remote client to connect the DNS Servers,

    Should I add the following lines on /etc/sysconfig/iptables

    -A RH-Firewall-1-INPUT -m state --state NEW -p udp --dport 53 -j ACCEPT
    -A RH-Firewall-1-INPUT -m state --state NEW -p tcp --dport 53 -j ACCEPT

    4. How can I add a second slave server with MySQL database replication with ssl encryption?
    I mean 3 DNS servers: Master/Slave1/Slave2

    5. Can I have PowerDNS and Bind in the same Master Server?
    I mean,
    5.1. speed Up Postfix Mail Server with Bind caching-nameserver
    5.2. Master DNS with PowerDNS

    Thanks for all your help.

    Just set up the second slave like you did for the first one, but make sure you use a different server ID.

    No, because they use the same port (53).
