SSH can do a lot more than just run commands, and in this installment we'll discover how to use SSH to securely transfer files from one computer to another.

By default SSH uses usernames and passwords to authenticate users, but in this installment we'll discover how to use SSH keys to make SSH both more secure and more convenient.

In this installment we introduce the Secure Shell, or SSH. SSH can do many things, but first and foremost it lets us run command, or entire command shells on remote computers securely

In this installment we put everything we have learned so far about networking together, and describe a workflow for diagnosing home networking problems.

This is the second part of a two-part installment looking at the Domain Name System, or DNS. DNS is a critical cog in the internet's wheel because it translates between human-friendly domain names, and computer-friendly IP addresses.

In this installment we learn about the Dynamic Host Configuration Protocol, or DHCP. This is the protocol that allows our computers to automatically discover their network settings, and without it portable computing devices simply wouldn't work.

This is the second part of a two-part installment exploring the second layer in the TCP/IP stack, the Internet Layer, and most importantly, the IP protocol. In particular we focus on the vitally important, but often confusing, concept of IP subnets. If you understand subnets, home networking becomes simple and obvious, if you don't it seems like black magic!

In this installment we start at the bottom of the TCP/IP stack, looking at the so-called link-layer, and in particular at Ethernet and the ARP protocol.
