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?
5.1. speed Up Postfix Mail Server with Bind caching-nameserver
5.2. Master DNS with PowerDNS
Thanks for all your help.
