Using Linux on a Chromebook + Relearning Linux

Also posted here .   Remember that second hand Chromebook I bought for a client years ago? They upgraded and gave it back, so let's put Linux or Ubuntu on it. I'm going to see if I can put a distro in there and switch between Chrome OS and Linux. It took longer to find the correct package to install than anything else. Out of the proverbial Chrome Development Mode box, it doesn't recognize apt, apt-get, or yum.  Nor does it recognize any attempts to install them. The Chromebook's Linux option installs Penguin, the default Linux Container on Chrome OS. It struggled to start, so I deleted the Linux container and tried again with success. Most instructions say to enable your Chromebook’s Developer Mode then open a certain terminal; Instead, I found you enable Linux Penguin through Chrome OS (Easy, check your settings) and use that containerized version. When you do this, Crostini is already installed, which is a more secure form of Crouton. Crouton is outdated. C...

How to Secure Your Linux Webserver

Article I don't remember which distro of Linux Webserver I used - My computer has Ubuntu, so my guess is that flavor. I'm working in datafile.txt - But not so fast! The initial edited datafile.txt file.

Linux User Management in the Terminal

From Jack Wallen @ Tech Republic  The user is made. -m gives them a home directory you can see with ls /home. A different user was made. They don't have a home directory because the -m parameter wasn't used. But they can at leave have a password. It doesn't show here. You can add a password when you make a user with -p .This one will appear.  -l means the user is made but locked out from logging in. You can put users into (normal) groups with -a (Modify user) -G (put in a group). The following numbers are the group ID. You can make multiple groups with the same ID .

AWS: Connecting to an EC2 Linux Instance

Haven't practiced this in a few months. Back to establish the basics. Before, I just jumped into the available white papers on Amazon's site. While informative, a lot of it went over my head. Learning the simpler things such as using EC2, Linux, and puTTY works to make the information stick. I'm using the yearly free tier of AWS for practice. Many things are run on Amazon's infrastructure - like Netflix. Have to keep up with that! But how do you use puTTY to connect to your Instance? You change the key Amazon gives you (.pem) to one with a .ppk extension using puTTYGen. Key blocked. Then you use said adjusted key, your given login name, and your public DNS IPv4 chain-code thing on your EC2 Management page (the blanked out square under 'Host Name (or IP Address)'). DNS IPv4 Chain-Code blocked. We have connectivity! What happened? I spun up a Virtual Machine on EC2 / AWS, installed an Amazon-variant of Linux, and SSH'd into it with pu...
