Simple script to connect multipleFortiClient SSL VPN client

Introduction:-

The FortiGate unit supports both SSL and IPSec VPN technologies. Each combines encryption and VPN gateway functions to create private communication channels over the Internet, which helps to defray physical network costs. Both enable you to define and deploy network access and firewall policies using a single management tool. In addition, both support a simple client/user authentication process (including optional X.509 security certificates). You have the freedom to use both technologies; however, one may be better suited to the requirements of your situation.

In general, IPSec VPNs are a good choice for site-to-site connections where appliance-based firewalls are used to provide network protection, and company sanctioned client computers are issued to users. SSL VPNs are a good choice for roaming users who depend on a wide variety of thin-client computers to access enterprise applications and/or company resources from a remote location.

Virtualization – Introduction – (Containerization)-setup-LXC

Introduction:-

What does Virtualization mean?

The simple explanation is that you create a virtual version of something that’s generally used for some type of execution. For example, if you were to partition a basic hard drive to create two hard drives, then they would be two ‘virtualized hard drives,’ as the hardware is technically a single hard drive that was digitally separated into two.Virtualization refers to the creation of a virtual resource such as a server, desktop, operating system, file, storage or network.

what are Containers?

Containers are a lightweight virtualization technology.In IT it is all about the need to run an application, not a virtual machine.In the end, it is the application user that has a need.This need is to run the application and no user will ever ask for a virtual machine.That is exactly one of the major design goals of the container technology.

A container is a virtualization method at the OS level.This allows multiple instances of an os to be running on the same kernel, which allows for a more efficient usage of available resources.

What is WordPress?

WordPress is a free and open-source content management system (CMS) based on PHP and MySQL.[5] WordPress is installed on a web server that is either part of an Internet hosting service or a network host in its own right. The first case may be a service like WordPress.com, for example, and the second case could be a computer running the software package WordPress.org.[6] A local computer may be used for single-user testing and learning purposes.

WordPress has a web template system using a template processor. Its architecture is a front controller, routing all requests for non-static URIs to a single PHP file which parses the URI and identifies the target page. Once downloaded, WordPress installation files have a size of about 20 MB.

Alternative for DD command with a progress report about how much has been written-dcfldd

1 ) DD Command:-

The dd command stands for “data duplicator” and used for copying and converting data. It is very powerful low level utility of Linux which can do much more like.

• Backup and restore the entire hard disk or partition.
• Backup of MBR (Master Boot Record)
• It can copy and convert magnetic tape format, convert between ASCII and EBCDIC formats,swap bytes and can also convert lower case to upper case.
• It can also be used by Linux kernel make files to make boot images.

Only superuser can run this command because you can face a big data loss due to its improper usage, so you should be very careful while working with this utility. At that moment data loss can convert the dd utility as a “data destroyer” for you

Ansible Playbook Example-1

What’s with the Name “Ansible”?

 Ansible was used to control a large number of remote ships at once, over vast distances. Think of it as a metaphor for controlling remote servers.

Introduction:-

Ansible playbooks are a way to send commands to remote computers in a scripted way. Instead of using Ansible commands individually to remotely configure computers from the command line, you can configure entire complex environments by passing a script to one or more systems.

Ansible playbooks are written in the YAML data serialization format. If you don’t know what a data serialization format is, think of it as a way to translate a programmatic data structure (lists, arrays, dictionaries, etc) into a format that can be easily stored to disk. The file can then be used to recreate the structure at a later point. JSON is another popular data serialization format, but YAML is much easier to read.

Ansible Agentless Automation

WiKi:-

Ansible is a free-software platform for configuring and managing computers which combines multi-node software deployment, ad hoctask execution, and configuration management.[1] It manages nodes (Linux nodes must have Python 2.4 or later installed on them, Windows nodes require PowerShell 3.0 or later) over SSH or over PowerShell.[2] Modules work over JSON and standard output and can be written in any programming language. The system uses YAML to express reusable descriptions of systems.[3]

Configuration management systems are designed to make controlling large numbers of servers easy for administrators and operations teams. They allow you to control many different systems in an automated way from one central location.
