If you're into trying out various distributions or enjoy having various Linux 'servers' to ssh into and play around with, then you should get started with single-board computers. They're cheap, robust and fun.

This quick tutorial focuses on the Odroid c2. The features vastly outweigh what's available for the popular Raspberry Pi.

Similar to the Raspberry Pi is the Orange Pi series of single board systems.

These single boards are not compatible with the Operating System (OS) images for Raspberry Pi. In this article we will cover installing and setting up an OS.

The Linux Kernel is often misunderstood or not even known about. To help everyone out we can go over some basics of the Kernel and help you to understand things better.

When dealing with files and folders on a system or even going through the contents of a file you will need to understand ‘Regular Expression’. ‘Regular Expression’ are characters used to define a pattern. The pattern can be used to search through a text file or listing files and folders.

Sometime instead of ‘Regular Expression’ you may see ‘regex’ or ‘regexp’.

There are many Linux gaming distros. Most of the gaming distros are based off of Debian, but this one is Red Hat. For those people who prefer Red Hat systems over Debian then this gaming system is for you.

For those who like a visually enhanced form of Linux then Ultimate Edition 5.4 is for you. The graphics are extremely nice compared to other versions of Linux I have seen.

With animated cursors and having its own desktop called ‘Budgie’ the Operating System (OS) is visually pleasing.

Sometimes on a network it is beneficial to know the Operating System (OS) of a machine. Accessing a system is easier when you know the OS because you can specifically search the Internet for known security holes in the OS. Granted, security holes are usually patched quickly, but you need to know when a security hole exists.

Scanning your own network to detect the OS types can help you to see what a hacker will be able to see about your network.

Another useful command for the Linux Foundation Certified SysAdmin (LFCS) is the 'sed' Command. The initials stand for 'Streaming EDitor'.

The 'sed' Command is an editor that edits the file as a stream. To stream a file is to pass it from another command using pipes (> or |) or load it directly into 'sed'.

Many people may have a user account on their system which they may not know the password to log in. Other passwords may also exist which can be recovered. This article will cover the use of Hashcat to find missing passwords. Of course, this process will not find every password, but it can help to attempt a recovery.

A lot of people who like to use their Linux system for gaming. There seems to be no shortage of gaming systems which can supply access to games. UALinux is a Ukrainian company which promotes the use of GNU/Linux. UALinux has created a Ubuntu version to fill the gap for gaming. The Operating System (OS) is called Ubuntu GamePack and is based off of Ubuntu 16.04.

Bluetooth is a wireless technology mainly for close range. The technology is managed by the Bluetooth Special Interest Group (SIG).

Most devices have Bluetooth ability such as smart phones, speakers, headphones, laptops, keyboards, mice, printers gaming consoles, etc. Having a basic understanding of Bluetooth will help you when dealing with the devices.

If you have been following the NMAP articles I have written then you may have noticed something important about the scans. NMAP prefers to perform a Ping. A Ping to NMAP is a test to verify that the system to be scanned is really on-line and exists. If NMAP is to scan multiple systems on a subnet, or a whole subnet, then it will first test which systems are available to scan.

The Linux Foundation Certified Systems Administrator has listed in the Domains and Competencies to be able to ‘Analyze text files’. This article will cover the use of six commands to analyze the contents of a text file. The six commands are: wc, cat, head, tail, more and less.

For those of you who may remember the puzzle game by Microsoft, as shown in Figure 1, you may be thinking “No way!”. The game will work in a round about way along with other classics from the time. The problem with Pandora’s Box is that Microsoft wrote the game specifically for the Pentium processor. Because of the specific code most people cannot play it anymore since Pentium systems are so obsolete. In this article you can run Pandora’s Box once again on nearly any newer system with Linux.

On Saturday, Inkscape made its move from Launchpad after a year or more of planning and reviewing different platforms as well as determining how to convert the codebase for each possible choice with the minimal amount of data loss factored in.
