Ansible is App deployment, configuration management and orchestration – all from one system.
It uses no agents and no additional custom security infrastructure, so it’s easy to deploy – and most importantly, it uses a very simple language (YAML, in the form of Ansible Playbooks) that allow you to describe your automation jobs in a way that approaches plain English. Continue reading
In Linux we have Conky in Windows Desktopinfo or BGinfo. Here below I would like to propose to use Desktopinfo. This is not as much of use for home users to extend their desktop by beatutifult intergated system info direct with the desktop wallpaper / background. The most common use would be for multiple M$ systems hosted in cloud, small business servers or farms where you remote often and want to have all the system info right on plate – on your background. This saves time thus increase performance of administrative tasks by easy visually identifying the system health and resources. Continue reading
I am using Conky as a system info which is directly embedded into my Linux desktop background. The rich configuration options and flexibility allows various data to be displayed in fully configurable format adding extra blink to the desktop wallpaper. Continue reading
Some IT technician words can make confuse and provide misunderstanding therefore please read the list below to be familiar with these expressions:
- Adware – if you have this type of programme loaded onto your computer, you will start getting pop-ups even when you’re not online! If you click on the pop-up it will take you to a specific web site where you will be encouraged to enter your credit card details. Typically these are scames, so our advice is to never buy anything using pop-ups that just appear on your screen.
A few keyboard short-cuts to use working in Linux terminal either in a text mode or desktop X session:
- [Ctrl] + [Alt] + [Fn] = it switches screens.
[Ctrl]+[Alt] + [F1] through [F6] are text-mode shell prompt screens and [F7] is the graphical desktop screen.
- [Ctrl] + [Alt] + [Delete] = When is used in graphic desktop session it shuts down Cent OS, Red Hat and should work similar with any other Linux distribution. To use only when the normal shutdown procedure does not work, this short-cut will display the desktop logout screen that allow you to logout, reboot, or shut down.
As the Packet Tracer network simulator from Cisco has been designed to help CCNA students go through a course, we cannot expect to work it with all stuff what is beyond of CCNA. Therefore I found really frustrated to make few configurations from LAB into PT, spending hours to figure out that is not possible to implement them. Continue reading
Socks proxy using SSH
Tunnelling over our Internet link it sounds already exiting, isn’t it?. But how difficult is it? Do we need any complex and sophisticated configuration of hardware and software? Hmm.. it is not necessary even to involve ipsec or ssl stack to create VPN. SOCKS is built in to OpenSSH so it’s trivial to run SOCKS proxy server with ssh client running with option -D. This option configures SSH client to listen on your local Linux box on specified by us tcp port. Then we will use SOCKS5 proxy configuration built into most of Internet browsers to connect to.
