DNS
The Domain Name System is really a must for any TCIP/IP network. It is a key component of the network. That is why it is the first service we will configure.
Here we will be using Bind, ISC's DNS server. Bind has a master/slave configuration, where the master gets the DNS changes and then updates the slave. It cannot run truly redundant, in the sense that only the master is allowed to get DNS changes, if the master is down, the slave cannot be updated.
In this setup we use the following IP-addresses for the master and slave:
- 192.168.1.34 master
- 192.168.1.35 slave
Configure the master, then the slave.
