Summary

The networking rules are ever-changing and fast-paced. Becoming a Network Engineer can be a lot of fun and provide a very profitable source of income. This chapter should be all you need to take your first steps in this exciting world of networking. In this chapter, you learned the following:

• The TCP/IP protocol suite forms the basis of the Internet.
• An IP address has a host part and a network part. The decision of which bits are in which part is based on the netmask.
• Routing is the process by which packets travel from one network to another. Most networks have a single default router that connects them to another, upstream network.
• The main tools for troubleshooting TCP/IP problems are ping, traceroute, and tcpdump.
• Linux provides several security tools. The Linux kernel itself provides a firewall, which is configured with ipchains.
