Scenario: Windows 10 on a HP tablet consistently stops on a routine Windows Update around 80%. Multiple reboots. No resolution. I turn to the Microsoft Support Forum, find no answer. Click on the Online Chat with Support.
Running a virtual Ubuntu server? Worried about security? Here's a nice tutorial on installing Fail2Ban on Ubuntu to help defend against brute-force attacks:
Would you like to try a new or different distribution of Linux? Have a couple of spare USB storage devices laying around the desk drawer? Then you can create your own bootable USB stick to give that distribution a test drive!
Check out the instructions: How to Create a Bootable USB Drive on Linux
Particularly pay attention to the steps to determine the path for your USB drive using the command
$ df -aTh
Tips: Before you plug in the USB drive, run the above command. Make a note of the drives found. Plug in the USB and rerun the command. The new drive found will be your USB stick.
Using the dd command is destructive! It will wipe out any data on the target USB drive, so be certain you don't have anything on the drive you need to keep. Not mentioned in the above tutorial, you most likely will need to run the command with 'sudo' to have elevated permissions. For example:
$ sudo dd bs=4M if=/path/to/your/iso.file of=/dev/sdc1 && sync
Also of note, the dd command does not have a progress indicator. So, you will need to patient since writing an iso image to USB can be a little slow.
Depending if you're a "glass half empty" or "glass half full" person, this article could be interpreted as either "You know you're a Linux Newbie if ..." or "Things I need to Learn about Linux" - you can decide:
One of the more handy programs (which is still free of charge) for trying out different Linux distributions is Oracle's VirtualBox. There is a small learning curve to get acquainted with virtualiztion, but still a good program.
One of the first issues that needs to be addressed is the default 640x480 screen resolution after installing a VM. Turning to Google, there are lots of posts about how to fix this, most of them outdated and addressing older versions of VirtualBox. For the remainder of this post, I'll be talking about VirtualBox version 4.3.26.
The LAMP stack is Linux, Apache, MySQL and PHP and used for web hosting. Installing on your local workstation for development and testing can be done from the command line.
Additional note: these instructions are for a local development installation of LAMP and does not include instructions for hardening. For a production installation further due diligence would be needed for security. See this article: How to Secure Ubuntu for the Web
Part of the learning curve with any new OS such as Linux is the underlying infrastructure. Such as getting around in a Linux/Unix file structure. Here are a couple of links to useful information:
Filesystem Hierarchy Standard (Wikipedia)
And sometimes you have to open up the Terminal and go exploring on the command-line to get used to how things look, especially if you've been using the DOS/Windows way of doing things for awhile.
About a year ago, I did a fresh install of Ubuntu 12.04 on an older Dell laptop. One of the few issues was with the WiFi connectivity.
There is a proprietary driver for the Dell Wireless 1395 WLAN mini-card (which is actually a Broadcom BCM 4312 under the hood) provided by the manufacturer here.
Also, more information about detecting and installing alternate drivers provided in the Ubuntu documentation is worth reading: Identifying Your Broadcom BCM43xx Chipset (PCI)
The steps that I discovered was:
"Compute Freely – a friendly place to start for the Free & Open Source Software and Linux curious."
Nice launch page with the top Linux distributions.
You've tried the "Live" DVD with Ubuntu to check it out. Now you're ready to take that big step and load Ubuntu on your PC, but still want to keep Windows old times sake. Dual booting is the answer!
