About network attack, detection and prevention – part 001.

Because I met various people users and admins who have trouble understanding some network tools will briefly present a small tutorial about common network attacks.
Basic teory
DOS attacks – is usually used to send a lot of traffic to the victim machine to consume its resources so that the legit users are not able to access the services.
Ping flood – this atack will send you a huge amount of Ping packets with packet size as big as possible. In windows you can specify the data/buffer size too.
MAC flooding – with this attack the attacker will transmit a lot of ARP packets to fill up the switch’s CAM table and this which means that the switch will broadcast the incoming packet to all the ports.
ARP spoofing – in this case you shall associate your MAC address to victim’s IP address by sending a specially crafted ARP frame.
Tools for simulating the attacks
Any software for networking with sniffing and detect can be detected by servers.
– Hackers used using Kali – debian distro linux (it contains a lot of tools).
– Ping flooding tool: Nping
– MAC flooding tool: Macof
– ARP spoofing tool: dSniff
Detection and prevention
Any network attacks or simulate attacks can be detected by hardware and software.
You can used also the Wireshark to detect the attacks.

Mandelbrot with three.js .

The Mandelbrot set is the set of complex numbers c for which the function f c ( z ) = z 2 + c {\displaystyle f_{c}(z)=z^{2}+c} {\displaystyle f_{c}(z)=z^{2}+c} does not diverge when iterated from z = 0 {\displaystyle z=0} z=0, i.e., for which the sequence f c ( 0 ) {\displaystyle f_{c}(0)} {\displaystyle f_{c}(0)}, f c ( f c ( 0 ) ) {\displaystyle f_{c}(f_{c}(0))} {\displaystyle f_{c}(f_{c}(0))}, etc., remains bounded in absolute value.wikipedia.org

You need to download the three.js – java script from threejs webpage.
The source code is simple. Come with default HTML5 page and javascripts.
One part of this will make vertex-shader and fragment shader, both is 2D shader type.
You need the canvas tag with id=”canv”.
The last part of source code is make to put all into one image processing by shaders.

Fix error: Install and uninstall windows LibreOffice.

When you try to install or uninstall LibreOffice software then this will want the old instalation file.
For example I want to install the new LibreOffice 5.1.52 software and the instalation file try to find the old LibreOffice_5.1.4_Win_x64.msi.
I fix this with download the LibreOfice_5.1.4.2_Win_x64.msi from here and renamed with LibreOffice_5.1.4_Win_x64.msi.
Also you need to use task manager to close all firefox browser tasks.
This will allow to install the new version of LibreOffice software.
