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.

Initial Installation

The first thing to do is to set up Linux on your system. Perform the installation…

When Ukraine became independent in 1991, the new country and its people had to learn to navigate an unfamiliar conceptual landscape that included “market economy”, “private entrepreneurship”, “freedom of choice”, and other terms that were, for all intents and purposes, unknown to ordinary Ukrainian…

When you log into a server you're usually met with a message from the management or administrator of the server. Generally, this will be something like "welcome to blah server, we review log files, etc..".

I'll usually throw in some fancy ascii artwork to remind me of 20 years ago

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).

The Host Operating System (OS) is the main Operating System installed on…

Probably one of the things that scares most new users is being able to get around within Linux on the command line. You know, changing directories, finding out where you are currently, etc..

This all comes over time. Hopefully, this video will help shed some light on it. Maybe try to follow along…

You'll come across a time that you'll need to add a user to the sudoers file. This is done by using the visudo command as root.

I created this video about a year ago - hopefully it will help someone out there.

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…

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…

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.

The fine folks at Ansible have posted 19 videos, most being about 40 minutes long.

* Applyting Ansible at HSBC
* Efficiency and Effectiveness…

Router Security
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…

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.

‘virsh’

The way to change some…

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.

On the Windows side of things, they have released documentation on a script called BothanSpy. This…

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…
