Default iptables PowerDNS Poweradmin MySQL Postfix Help Request

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
http://postfixmail.com/blog/index.ph...r-mail-server/
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

http://www.howtoforge.com/how-to-set...-on-centos-5.4
http://www.howtoforge.com/installing...-on-centos-5.2

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).
