Taming the Terminal

We're back after a (planned) lengthy hiatus! In this instalment, Bart teaches us how to protect our secrets while working in the Terminal. Secrets can include passwords, API keys, and any other sensitive information you'd like to protect. Without the tools Bart teaches us, any secrets you type into the Terminal will be in your history file in plain text, and with AI, possibly hoovered up as traini...

In this episode of Taming the Terminal, Bart winds up our series within a series all about the Terminal command TMUX. In this final piece he teaches us first how to string commands together to create the TMUX sessions we want with the screens split and the processes running in each pane as we like them. After teaching us how to string them together he shows us how to make a little script file we c...

This week's episode of Chit Chat Across the Pond was another installment of Taming the Terminal. Two weeks ago Bart taught us the basics of a technology called `tmux`, or terminal multiplexer that allows you to access the same server in many different ways at the same time. He covered how `tmux` replaces the deprecated `screen` but he didn't go much further. In this rather light and easy-to-follow...

When Bart first started the Taming the Terminal series in October of 2015, he purposely declared every installment to be "of n" where n was not defined. It's been 3 years since there was an episode of Taming the Terminal, but today we've got a new one for you. In Taming the Terminal 36, recorded in 2016, Bart introduced us to a nifty command-line tool called screen. Screen allowed you to ssh into...

In 2017 on Taming the Terminal installment 37 of n, Bart taught us about SSH agents and the advantages of using a passphrase to further protect your SSH keys. In the intervening four years, things have changed a bit in macOS, so we decided to do a supplemental update to installment 37. We review a bit about what SSH Keys are (from installment 30) and then discuss how much easier and cleaner things...

As promised, Taming the Terminal isn't over yet! Bart Busschots joins us to talk about SSH Agents. We'll talk about how Apple changed things in El Capitan so that you'll have to log into your server with your passphrase more often, and how Bart has a fix for that problem. Bart does a great job of reminding us of what we learned about SSH back in parts 29 and 30 of Taming the Terminal so it's easie...

It’s been a long time since we did a Taming the Terminal episode but we’re back with episode 36 of n, screen and cron. You’ll hear me say this is episode 35, but with all these numbers flying around we got mixed up! In any case, in this installment Bart teaches us two unrelated but really cool things you can do with the Terminal in macOS or Linux. The first is cron, a tool that lets you schedule s...

In this installment we look at three terminal commands for interacting with the world wide web from the terminal. We'll look at a command-line based browser, and commands for downloading files and viewing HTTP headers. As always, you can get to Bart's fabulous tutorial shownotes at ttt.bartificer.net/...

In this installment we learn how to use SSH config files to automate some aspects of SSH, creating what amount to bookmarks to servers we connect to often. We'll also look at some GUIs for storing SSH connection details. As always, you can get to Bart's fabulous tutorial shownotes at ttt.bartificer.net/...

In this installment we look at how the HTTP protocol works, this is the protocol that powers the world-wide-web. As always, you can get to Bart's fabulous tutorial shownotes at ttt.bartificer.net/...

In this installment we'll look at how SSH tunnels can be used to secure all kinds of network traffic, not just remote commands and file transfers. Most people won't need the power of SSH tunnels very often, if at all, but when you do need them, you probably REALLY need them, so it's important to know what's possible, even if you don't remember the details. As always, you can get to Bart's fabulous...

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. As always, you can get to Bart's fabulous tutorial shownotes at ttt.bartificer.net/...

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. As always, you can get to Bart's fabulous tutorial shownotes at ttt.bartificer.net/...

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. As always, you can get to Bart's fabulous tutorial shownotes at ttt.bartificer.net/...

In this installment we put everything we have learned so far about networking together, and describe a workflow for diagnosing home networking problems. As always, you can get to Bart's fabulous tutorial shownotes at ttt.bartificer.net/...

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! As always, you can get to Bart's fabulo...
