Fedora 27 : Test install with dotnet from microsoft.

Today I test how to install dotnet from Microsoft team development with Fedora 27.
The Microsoft team come with RedHat packages version - 7.3 and is an old type of packages.
They show us this old way how to deal with this issue , see this link.
I used this command lines into sudo user:

#rpm --import https://packages.microsoft.com/keys/microsoft.asc
#sh -c 'echo -e "[packages-microsoft-com-prod]\nname=packages-microsoft-com-prod 
\nbaseurl=https://packages.microsoft.com/yumrepos/microsoft-rhel7.3-prod\nenabled=1
\ngpgcheck=1\ngpgkey=https://packages.microsoft.com/keys/microsoft.asc" > 
/etc/yum.repos.d/dotnetdev.repo'
#dnf update
#dnf install libunwind libicu compat-openssl10
#dnf install dotnet-sdk-2.0.2
#dotnet new console -o myApp
#cd myApp
#dotnet run

As you can see the dotnet working well with Fedora 27.
I would have preferred a classic dnf installation for reasons of later incompatibility.
This fact only indicates a tangential interest and a clear reason in microsoft capabilities to cover dotnet's area of interest versus linux distributions.

Fedora 27 : Nettacker tool .

This tool for internet of things is a network of physical objects such as household devices.
This goal let Nettacker tool to automated for information gathering, vulnerability scanning and eventually generating report for networks, including services, bugs, vulnerabilities, misconfigurations and information. Is able to use SYN, ACK, TCP, ICMP and many other protocols to detect and bypass the Firewalls/IDS/IPS and devices.
The project is at the moment in research and development phase and most of results/codes are not published yet.

• is a IoT Scanner - Internet of Things Scanner;
• Python Multi Thread and Multi Process Network Information Gathering Vulnerability Scanner;
• Service and Device Detection ( SCADA, Restricted Areas, Routers, HTTP Servers, Logins and Authentications, None-Indexed HTTP, Paradox System, Cameras, Firewalls, UTM, WebMails, VPN, RDP, SSH, FTP, TELNET Services, Proxy Servers and Many Devices like Juniper, Cisco, Switches and more);
• Network Service Analysis;
• Services Vulnerability Testing;
• Services Brute Force Testing;
• HTTP/HTTPS Crawling, Fuzzing, Information Gathering and more;
• Python and Nmap Module Version [ .nse  Lua language ];

How to install into fedora 27.

git clone https://github.com/Nettacker/Nettacker.git
cd Nettacker
pip install -r requirements.txt
python nettacker.py -h

If you run it you will see the help of this tool:

Let's test it:

python nettacker.py --graph d3_tree_v1_graph' -i 127.0.0.1 -m all

The result of this is show in the next image:

Fedora 27 : the Docker platform .

The Docker team company tell us:

Docker is the company driving the container movement and the only container platform provider to address every application across the hybrid cloud. Today’s businesses are under pressure to digitally transform but are constrained by existing applications and infrastructure while rationalizing an increasingly diverse portfolio of clouds, datacenters and application architectures. Docker enables true independence between applications and infrastructure and developers and IT ops to unlock their potential and creates a model for better collaboration and innovation.

The Docker platform come many features, so let's see them:

• use containers; 
• containers are lightweight;
• containers are standalone packages;
• each containers contain everything needed to run an application (code, libraries, runtime, system settings, and dependencies);
• the biggest difference between a container and a virtual machine: containers is not a full-blown operating system platform;
• applications are isolated in containers;
• docker come with: Pricing Plans;

Let's start with the installation and testing of the docker (you need a sudo account):

#sudo dnf install docker
#newgrp docker
#sudo groupadd docker && sudo gpasswd -a ${USER} docker && sudo systemctl restart docker
#sudo usermod -a -G docker $USER
#sudo systemctl start docker
#sudo systemctl enable docker
#sudo systemctl stop docker
#sudo systemctl restart docker

This commands will install docker with dnf tool and will add your user to group docker.
The command with systemctl is used to test the docker services.
You can test the docker by searching and start applications:

#sudo docker search hello-world
#sudo docker run hello-world

The result of the run hello-world is this:

Fedora 27 : load81 simple lua game engine .

Today I tested something simple with Fedora 27 and scheduling in.
This is a SDL based Lua programming environment for children called load81.

The author teel us:

The name Load81 originates from the fact that in popular Commodore home computers the command LOAD "*",8,1 would load the first program on the disk starting from the file-specified memory location.

Load81 is written in ANSI C and uses SDL and SDL_gfx and SDL_image libraries.
I installed all these libraries and everything worked very well.
Once taken from github with clones I tested the examples in the examples folder and worked well from the first time.
The examples folder come with simple examples and some simple games.
Create your lua script and use this command to run it:

./load81 example.lua

All running scripts require a graphical display account.
They worked very well on my normal account and I got a run-time error on my root account.
From examples, I took the triangles.lua script to illustrate how this game engine looks and works.

function setup()
    background(0,0,0);
end

function draw()
    fill(math.random(255),math.random(255),math.random(255),math.random())
    triangle(math.random(WIDTH),math.random(HEIGHT),
             math.random(WIDTH),math.random(HEIGHT),
             math.random(WIDTH),math.random(HEIGHT))
end

This is screenshot of triangles.lua script:

Fedora 27 : lua programming with torch and love 2d.

The Lua programming language is a good programming tool to start and test your programming skills.
Lately, the capabilities of computers and computer networks have increased exponentially.
The programming language allows the user simple programming possibilities with essential advantages.
I will illustrate some programs and frameworks that may be of special interest to you:

• Wireshark has an embedded Lua interpreter and you can be used to write dissectors (to decode packet data), post-dissectors and taps;
• Torch is a scientific computing framework with wide support for machine learning algorithms;
• Love 2D is a framework for making 2D games for windows, linux and android;

Today I start with install lua , torch and love 2D.
This work very well. If you use root accont then love command will work only with display SDL. This means you have to use a normal user, not a root user.
I used dnf install tool for lua and love 2d and github for torch.
The result can be seen in the following screenshots:

News: About the new Fedora 27 .

Today I tried to make a simple installation of Fedora 26 which I did without problems.
After that, the software update come with the option to upgrade all of your Fedora system software to the new Fedora 27.
The work of the Fedora team is appreciated for the work being done to create this new version.
For those who have been following the evolution of the design team over the course of Fedora's development, they will see evolution and quality in the new Fedora design.
Most software used by me was implemented without errors and everything seems to work very well.
Here are some screenshots made during the installation process:
