Chapter 7. Managing Your Ubuntu Server Network
In Chapter 4, Connecting to Networks, we discussed connecting networks. We saw how to set the hostname, manage network interfaces, configure connections, use Network Manager, and more. In this chapter, we'll revisit networking, specifically to set up the resources that will serve as the foundation of our network. The majority of this chapter will focus on setting up the DHCP and DNS servers, which are very important components of any network. In addition, we'll also set up a Network Time Protocol (NTP) server to keep our clocks synchronized. We'll even take a look at setting up a server to act as an Internet gateway for the rest of our network.
Along the way, we'll cover the following topics:
- Planning your IP address scheme
- Serving IP addresses with
isc-dhcp-server - Creating a secondary DNS server
- Setting up an Internet gateway
- Keeping your system clock in sync with NTP
