I've been using vim for about 22 years and even today find little tips and tidbits that I didn't know about! This article will go through some of the things I use often in vim - and I hope we'll get some great replies with what some of your favorite tips are!

Part of any Linux system as well as the LFCS exam, is the understanding and use of Root permissions. Root permissions give access to the permissions to perform any function on a Linux system. It is what someone using Windows would call Administrative privileges.

Docker is a utility which allows a special type of virtualization. Docker allows for a program to be run “virtually” on a system by using a Docker image. An image can be downloaded or created which can then be run. Once the image is loaded and executed it is now a container. A container has allocated resources set aside for the program within the container.

From their website, "WireGuard® is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPsec, while avoiding the massive headache."

Installing Wireguard is a straightforward procedure. Start by installing the Linux header files for your kernel using the following command..

Learning about file permissions for the LFCS exam is important, but it is also very important to know in everyday use of Linux.

Keep in mind that all of the file permissions are used for every format except the FAT formats such as FAT32.

When running commands in a Terminal there are many ways information can be redirected. There are a few redirection conventions usable within a Terminal to make things easier.

Part of the LFCS exam covers archiving, compressing, unarchiving and uncompressing files. The ability to perform these on files is a useful tool for any Linux user. This article will cover the use of seven commands to perform the actions needed for the archival and the compression of files.

A full install on a USB stick will make a perfect Fix stick. On a device with Persistence the Persistence is usually a compressed file which stores all of the data on the OS which is updated from the original install files. If the Persistence file should become corrupted then all data is lost. A main issue is that a Persistent drive does not allow for a kernel update. The full install will function just like a regular installation on a hard disk. The USB stick will make the OS more portable and, of course, allow for kernel updates.

In the LFCS exam you may be asked to create or modify files. One simple way is to use the program ‘Nano’. Other programs can be used, but it is up to you which program you use. Remember that the point of the exam is not to use any specific tool, but to get the task completed that you are given.

With a standard Linux System you can use ‘libvirt’ to manage Virtual Clients (VC). For more virtual ability you can add Xen to Linux.

The basic installation of Xen is not a complicated one.

I believe that some of the main factors that impede the spread of GNU/Linux in Ukraine are, first, the continuing prevalence of online piracy and a pervasive stereotype that such software is designed solely for computer geeks because of its complexity, and second, the insufficient number of computer games in the “A” category.

Virtual Clients (VC) or Guests run on a Virtual system. The system is managed by a Hypervisor which handles the CPU and memory. The Clients are set up either as a Hardware Virtual Machine (HVM) or Paravirtualization (PV).

Knowing the systems on a network and what Operating System (OS) they are running may not be enough for an Administrator to know. You can scan systems on a network and determine what Services and versions of a Service are running. It may be important to be able to see and know what a hacker can learn about your systems.

Streaming audio to your local network or even to the Internet is possible on Linux. For those who like to listen to music wherever they go makes having your own radio station very handy.

Keep in mind that this will use some of your network bandwidth, but it is a nice feature to have when you want music handy everywhere.

If you missed out on going to #AnsibleFest in London last month don't worry, you can catch up on some of the things you missed in the videos of presentations.

Anyone connecting to the Internet needs a Router. The Router can provide direct connection by an Ethernet cable (RJ-45) or through Wi-Fi. Wi-Fi is, of course, wireless and does not require any cables. Because the connection is made without cables anyone with nearly any device can see your network.

In previous articles I discussed the installation and basic use of libvirt. I also covered the libvirt Graphical User Interface (GUI) called Virt-Manager.

This article will cover more details of the configuration on various topics that aren’t obvious to set.

WikiLeaks yesterday released documentation on two very specific scripts meant to steal OpenSSH login credentials from the client side. One script is for Windows clients, the other for Linux clients.

There are times when you may need to compare two files to check if they are the same. For instance, if you have two or more servers all running the same Operating System (OS) and on one server a file is causing issues then you can see if they are different. If they are different then it may be as simple as copying the one file from the working server to the failing server.

LibreOffice is looking for a mascot and you could be the creator of it! In their announcement, they mention some of the popular mascots out there, like Java's Duke, the SUSE Geeko, and KDE's Konqui.
