Abstract. The MAC, IP address and network name are network Ids, which allow proper communication of computers in a network. The IP address identifies a logical and hierarchical, to an interface of a device within a network using IP protocol. The MAC (Media Access Control) is a 48-bit identifier that uniquely corresponds to an Ethernet network, also known as the physical address. This project describes how to obtain these addresses and the names of network devices, also are described the state of the TCP, ICMP and UDP protocols of the computer where is running the application.

Resumen. La dirección MAC, dirección IP y el nombre de red son identificadores de red, que permiten la comunicación correcta de las computadoras en una red. La dirección IP identifica, de manera lógica y jerárquica, a una interfaz de un dispositivo dentro de una red que utilice el protocolo IP. La dirección MAC (control de acceso al medio) es un identificador de 48 bits que corresponde de forma única a una Ethernet de red, conocida también como la dirección física. En este proyecto se describe como obtener estas direcciones así como el nombre de los dispositivos de red, también se describen el estado de los protocolos TCP, ICMP y UDP del ordenar donde se ejecuta la aplicación.

INTRODUCTION

This article talks about how get the address MAC and the IP (Internet protocol) of LAN devices, it shows too the hostname of every one of the devices.

This small application tries to capture the status of some network protocols, like IP, TCP, ICMP and UDP.

The program was developed using some commands which are nast and netstat and implemented in java. These commands provide us the necessary information to obtain the requirements which we describe in this article.

MAC ADDRESS

The MAC address is a unique value associated with a network adapter. MAC addresses are also known as hardware addresses or physical addresses. They uniquely identify an adapter on a LAN.

MAC addresses are 12-digit hexadecimal numbers (48 bits in length). By convention, MAC addresses are usually written in one of the following two formats:

MM:MM:MM:SS:SS:SS

The first half of a MAC address contains the ID number of the adapter manufacturer. These IDs are regulated by an Internet standards body (see sidebar). The second half of a MAC address represents the serial number assigned to the adapter by the manufacturer. In the example:

00:A0:C9:14:C8:29

The prefix 00A0C9 indicates the manufacturer is Intel Corporation.

Whereas MAC addressing works at the data link layer, IP addressing functions at the network layer (layer 3). It's a slight oversimplification, but one can think of IP addressing as supporting the software implementation and MAC addresses as supporting the hardware implementation of the network stack.

IP ADDRESS

An Internet Protocol (IP) address is a numerical label that is assigned to devices participating in a computer network that uses the Internet Protocol for communication between its nodes. An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there.

IP addresses specify the locations of the source and destination nodes in the topology of the routing system. For this purpose, some of the bits in an IP address are used to designate a subnetwork. The number of these bits is indicated in CIDR notation, appended to the IP address; e.g., 208.77.188.166/24.

NAST

The Network Analyzer Sniffer Tool or nast is a packet capturing program that displays the captured information in various ways depending on the command line options you specify.

IP

Network layer protocol in the TCP/IP stack offering a connectionless internetworking service. IP provides features for addressing, type-of-service specification, fragmentation and reassembly and security.

TRANSMISSION CONTROL PROTOCOL (TCP)

TCP is the protocol used as the basis of most internet services. It is used in conjuction with the internet protocol (IP). It allows for reliable communication, ensuring that packets reach their intended destinations

INTERNET CONTROL MESSAGING PROTOCOL (ICMP)

Internet messaging protocol. Network layer internet protocol that reports errors and provides other information relevant to IP packet processing.

USER DATAGRAM PROTOCOL (UDP)

A connectionless transport layer protocol in the transmission Control Protocol/Internet Protocol (TCP/IP) stack. UDP is a simple protocol that exchanges datagrams without acknowledgments or guaranteed delivery, and requires that error processing and retransmission be handle by other protocols.

INTRODUCCION

El poder manejar programas en Ubuntu y en Windows hoy en día es un privilegio, sin embargo hay que tener muy en claro las diferencias de cada sistema operativo en este articulo les mostramos un ejemplo donde obtenemos la ip y la Mac address tanto en Windows como en Ubuntu, realizado en la plataforma net beans.

DEFINICIONES

Dirección IP: Una dirección IP es un número que identifica de manera lógica y jerárquica a una interfaz de un dispositivo (habitualmente una computadora) dentro de una red que utilice el protocolo IP (Internet Protocolo), que corresponde al nivel de red del protocolo TCP/IP. Dicho número no se ha de confundir con la dirección MAC que es un número hexadecimal fijo que es asignado a la tarjeta o dispositivo de red por el fabricante, mientras que la dirección IP se puede cambiar. Esta dirección puede cambiar 2 ó 3 veces al día; y a esta forma de asignación de dirección IP se denomina una dirección IP dinámica (normalmente se abrevia como IP dinámica).

Mac address: En redes de ordenadores la dirección MAC (siglas en inglés de Media Access Control o control de acceso al medio) es un identificador de 48 bits (6 bloques hexadecimales) que corresponde de forma única a una Ethernet de red. Se conoce también como la dirección física en cuanto identificar dispositivos de red. Es individual, cada dispositivo tiene su propia dirección MAC determinada y configurada por el IEEE (los últimos 24 bits) y el fabricante (los primeros 24 bits) utilizando el OUI. La mayoría de los protocolos que trabajan en la capa 2 del modelo OSI usan una de las tres numeraciones manejadas por el IEEE: MAC-48, EUI-48, y EUI-64 las cuales han sido diseñadas para ser identificadores globalmente únicos. No todos los protocolos de comunicación usan direcciones MAC, y no todos los protocolos requieren identificadores globalmente únicos.

NetBeans: a plataforma NetBeans permite que las aplicaciones sean desarrolladas a partir de un conjunto de componentes de software llamados módulos. Un módulo es un archivo Java que contiene clases de java escritas para interactuar con las APIs de NetBeans y un archivo especial (manifest file) que lo identifica como módulo. Las aplicaciones construidas a partir de módulos pueden ser extendidas agregándole nuevos módulos. Debido a que los módulos pueden ser desarrollados independientemente, las aplicaciones basadas en la plataforma NetBeans pueden ser extendidas fácilmente por otros desarrolladores de software.

El siguiente programa muestra como se puede obtener la IP y la Mac de una red de computadoras usando el Netbeans en Linux al momento que se corre el programa este puede capturar los dos protocolos que se han dicho y el código es el siguiente:

Conclusiones:

Con el desarrollo del programa nos pudimos dar cuenta que cada computadora tiene una dirección IP que es un numero que identifica de manera lógica a una interfaz de un dispositivo que se encuentra dentro de una red que utilice el protocolo IP este número puede crear una red dentro de internet conectándolo con alguna otra computadora con el mismo número IP, en este programa que se muestra anteriormente realiza la obtención de la dirección IP y la MAC address al momento de ejecutarlo en la plataforma de NetBeans captura los dos protocolos mostrándolos en la pantalla, en otro caso en el sistema operativo Ubuntu o Linux entrando desde lugares, terminal aparece un cuadro en el que para saber cuál es la dirección en la red por medio del IP se le da la instrucción.

#ifconfig

y automáticamente te manda el resultado que en ese momento se encuentra en la red WLAN que puede cambiar varias veces al día aquí mismo te muestra la MAC en una red LAN que es individual , cada dispositivo tiene su propia dirección MAC determinada y configurada, después para conectar dos o más computadoras en red con este número lo insertas en las computadoras donde dice http: e introduces el numero:

http://[ la dirección IP que dice la WLAN]

Install Mono 2.4 on Ubuntu

Ubuntu ships with Mono pre-installed, but due to the rapid release cycles on the Mono project, the version that ships with Ubuntu is

often outdated by the time the Ubuntu release ships. Due to the impressive release schedule of Mono, you do really need to keep up

with the new releases as every new release dramatically improves the entire framework.

Unfortunately for Ubuntu users, there are no dedicated Ubuntu packages for download from the Mono Project web site, which means that

you best bet is be to compile the project yourself. While I know that most Linux newbies find that concept intimidating, it actually

isn't nearly as hard as it sounds.

To that end, I'll walk you through compiling and installing the latest release of Mono (version 2.4 at time of writing) on Ubuntu.

Note that these instructions should also work on newer versions of Mono.

These instructions were created by installing Mono 2.4 on an absolutely fresh installation of Ubuntu. For those Windows users wishing

to try this out at home, I would suggest installing Ubuntu on a Virtual PC 2007 virtual machine. Arcanecode has an excellent post on

getting this to work first time.

IMPORTANT: If you're installing on a VPS, make sure that you have at least 400 MB of RAM available, or otherwise the mono compilation

process will fail.

WARNING

Following these instructions will result in all your pre-installed Mono applications being removed from your Ubuntu box. In most cases

the only way to get them back is going to be by installing them from source too (not always a bad idea).

If you'd like to play with Mono 2.4, but keep things like F-Spot and Beagle, I would suggest rather using the instructions

provided by Jan Dzik.

Update: I now have a script that automates the install, see this post: Mono Compile & Install Script

Installing Mono

Open a terminal window if you're using the Ubuntu GUI or log on using SSH if you're accessing a remote server.

All these instructions assume that you have root privileges, so if you're not logged in as root, enter the following and

enter you password when prompted.

$ sudo bash

First you need to remove the version of Mono that is pre-installed with Ubuntu.

$ apt-get remove mono-common

That will remove all the extra packages that are installed with mono as they all depend on it. Be aware that it will also remove

applications like f-spot and beagle, which will have to be re-installed after the mono upgrade if you wish to use them.

Next, create a folder for the source code you're about to compile:

$ mkdir /src

Then change to the src directory:

$ cd /src

Make sure that your /etc/apt/sources.list file has the universe and multiverse repositories included. If you installation didn't

have any internet connectivity, there may be a chance that the installer disabled those repositories due to being unable to verify

them. If that is the case, do the following:

$ nano /etc/apt/sources.list

Remove the # characters from the universe and multiverse entries and save the file (a Nano Basics Guide is available for people new

to nano). I personally just enable everything.

Refresh the apt-get database.

$ apt-get update

You now need to install some Mono build dependencies (and some optional enhancements):

$ apt-get install build-essential pkg-config libglib2.0-dev bison libcairo2-dev libungif4-dev libjpeg62-dev libtiff4-dev gettext

Download libgdiplus:

$ wget http://ftp.novell.com/pub/mono/sources/libgdiplus/libgdiplus-2.4.tar.bz2

$ tar -xvf libgdiplus-2.4.tar.bz2

$ cd libgdiplus-2.4/

Now we can compile libgdiplus and install it:

$ ./configure --prefix=/usr/local; make; make install

Now go make yourself a snack, especially if you're doing this on a VM

After the compilation finally finishes, we need to make sure the new packages are visible to the system:

$ sh -c “echo /usr/local/lib >> /etc/ld.so.conf”

$ /sbin/ldconfig

Now change back to the /src folder and download the latest release of mono (about 17 MB):

$ cd /src

$ wget http://ftp.novell.com/pub/mono/sources/mono/mono-2.4.tar.bz2

Extract the compressed file, change into the mono folder and compile:

$ tar -xvf mono-2.4.tar.bz2

$ cd mono-2.4

$ ./configure --prefix=/usr/local; make; make install

You can go make yourself a gourmet meal at this point as the compilation process takes a seriously long time (ok, maybe not that

long, but us generation X/Y types don't really have the patience for C++ compilation).

Add mono to the bash path:

$ nano ~/.bashrc

And add the following lines at the end:

PATH=/usr/local/bin:$PATH

LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH

In order for the changes to take effect, you need to either close and open your terminal again, or simply type:

$ bash

to start a new instance of bash command line.

To check your new mono version, type:

$ mono -V

You should see the following:

Mono JIT compiler version 2.4 (tarball Wed Apr 1 04:49:16 CDT 2009)

TLS: __thread

GC: Included Boehm (with typed GC)

SIGSEGV: altstack

Congratulations, you have a working copy of the latest Mono released installed on your Ubuntu machine!

Installing XSP

XSP is the Mono web server that Apache delegates to (via mod_mono) when serving ASP.NET pages on Linux. In order

to run ASP.NET pages

you will need to compile and build the XSP web server.

Change to your /src directory, download the XSP sources, unzip them and compile:

$ cd /src

$ wget http://ftp.novell.com/pub/mono/sources/xsp/xsp-2.4.tar.bz2

$ tar -xvf xsp-2.4.tar.bz2

$ cd xsp-2.4/

$ ./configure --prefix=/usr/local; make; make install

Once the compilation is done, we can test the XSP server. Change to the XSP test installation folder and run the XSP server:

$ cd /usr/local/lib/xsp/test

$ xsp2

You should see something like the following:

xsp2

Listening on address: 0.0.0.0

Root directory: /root

Listening on port: 8080 (non-secure)

Hit Return to stop the server.

Open your browser and point it to http://localhost:8080 (or your domain/ip if you're doing this remotely). You should see the XSP test page.

Installing Mod_Mono

Mod_mono is the name of the apache2 module that links the XSP server and apache. This allows for apache to handle all incoming

requests and hand them off to the XSP process in order to server your ASP.NET pages. You only need to install Mod_mono if you

plan on using Apache2 to serve web pages. You will also need to have apache2 (and it's development files) pre-installed to

compile mod_mono.

Install apache2 and the necessary build dependencies:

$ apt-get install apache2 apache2-threaded-dev

Once that's done, we can compile mod_mono.

Change to our source directory, download the mod_mono sources, unzip them and compile:

$ cd /src

$ wget http://ftp.novell.com/pub/mono/sources/mod_mono/mod_mono-2.4.tar.bz2

$ tar -xvf mod_mono-2.4.tar.bz2

$ cd mod_mono-2.4/

$ ./configure --prefix=/usr/local; make; make install

We need to include the mod_mono.conf file in the apache2 configuration file, so open the apache2.conf file in a text editor:

$ nano /etc/apache2/apache2.conf

Scroll to the bottom of the file and include the following line:

Include /etc/apache2/mod_mono.conf

Now lets copy the test content from XSP to our apache2 public folder to we can have an ASP.NET application with which to test the

mod_mono installation:

$ cp -r /usr/local/lib/xsp/test /var/www/test

When you compile Mod_mono from source, the necessary apache2 configuration files are not created for you, so we will have to do them manually.

Firstly, create the mod_mono.load file with a text editor:

$ nano /etc/apache2/mods-available/mod_mono.load

Add the following line to the file:

LoadModule mono_module /usr/lib/apache2/modules/mod_mono.so

Next we create the mod_mono.conf file:

$ nano /etc/apache2/mods-available/mod_mono.conf

Add the following to the file:

AddType application/x-asp-net .aspx .ashx .asmx .ascx .asax .config .ascx

DirectoryIndex index.aspx

include /usr/local/lib/mono/2.0/mono-server2-hosts.conf

Next, create the mono-server2-hosts.conf file:

$ nano /usr/local/lib/mono/2.0/mono-server2-hosts.conf

And add the following:

<IfModule mod_mono.c>

MonoUnixSocket /tmp/.mod_mono_server2

MonoServerPath /usr/local/lib/mono/2.0/mod-mono-server2.exe

AddType application/x-asp-net .aspx .ashx .asmx .ascx .asax .config .ascx

MonoApplicationsConfigDir /usr/local/lib/mono/2.0

MonoPath /usr/local/lib/mono/2.0:/usr/local/lib

Configure Apache2 Virtual Hosts

The virtual hosts configuration really requires a tutorial on its own, but for now I'll just show you how to make the test application

the default site on your apache2 server.

Edit the default virtual host file for apache2:

$ nano /etc/apache2/sites-enabled/000-default

Replace the contents of the file with the following (you may want to backup the file first):

<VirtualHost *>

ServerName www.local.com

ServerAdmin webmaster@localhost

DocumentRoot /var/www/test

DirectoryIndex index.html index.aspx

MonoDocumentRootDir “/var/www/test”

MonoServerPath rootsite “/usr/local/bin/mod-mono-server2”

MonoApplications rootsite “/:/var/www/test”

<Directory /var/www/test>

MonoSetServerAlias rootsite

SetHandler mono

AddHandler mod_mono .aspx .ascx .asax .ashx .config .cs .asmx

</Directory>

</VirtualHost>

Now restart apache2:

$ /etc/init.d/apache2 restart

Now open your browser and navigate to http://localhost/. You should see the XSP test web app appear.

Restart Errors

When you restart apache2 using the command above, you are likely to see an error message similar to the following:

• Restarting web server apache2

[Fri Nov 06 00:41:41 2009] [crit] (13)Permission denied: Failed to attach to existing dashboard, and removing dashboard

file '/tmp/mod_mono_dashboard_XXGLOBAL_1' failed (Operation not permitted). Further action impossible.

This is quite normal and will not affect the operation of your Mono websites.

INSTALL CUDA 2.3 ON UBUNTU 9.10

BY TOGNU

1. Open a terminal and paste the following commands to add the Launchpad repository:

-Ubuntu Karmic Koala

sudo add-apt-repository ppa:nvidia-vdpau/ppa

-Ubuntu Jaunty Jackalope, Intrepid Ibex, Hardy Heron:

sudo sh -c “echo 'deb http://ppa.launchpad.net/nvidia-vdpau/ppa/ubuntu UBUNTU_VERSION main' >> /etc/apt/sources.list”
 
sudo sh -c “echo 'deb-src http://ppa.launchpad.net/nvidia-vdpau/ppa/ubuntu UBUNTU_VERSION main' >> /etc/apt/sources.list”

In the two lines above, replace UBUNTU_VERSION with your Ubuntu version (in lowercase: jaunty, intrepid or hardy).

2. Import the GPG key (skip this for Karmic Koala if you used the add-apt-repository command):

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys CEC06767

3. Now you can install the Nvidia 190.xx stable drivers:

sudo apt-get update && sudo apt-get install nvidia-190-modaliases nvidia-glx-190

or 185.xx:

sudo apt-get update && sudo apt-get install nvidia-185-modaliases nvidia-glx-185

Install the drive using envyng

Code:

sudo apt-get install envyng-core;
 
envyng -t

use the option 1 Install the Nvidia driver,now the option 0 and restart you computer.

The new driver its showed

well, now open a terminal and put in

Code:

sudo apt-get install build-essential libglut3-devsudo
 
sudo apt-get install mesa-common-dev freeglut3-dev glutg3-dev libglut3
 
 

Furthermore we also need to get 3 more packages namely

sudo apt-get install libxmu-dev

sudo apt-get install libxmu-headers

sudo apt-get install libxi-dev

These can be installed with sudo apt-get in a terminal or by finding them in synaptic.

With these downloaded and installed we can continue and install the Nvidia driver. Note that this is on a fresh install and there are more steps to be taken if you are doing it with an older Nvidia driver already installed. There are already posts on the forum about that so I wont go into that here.

Next we need to install the toolkit. To do this we open a terminal and type in

Code:

chmod +x ./cudatoolkit_2.3_linux_64_ubuntu9.04.run
 
sudo ./cudatoolkit_2.3_linux_64_ubuntu9.04.run

You get to pick your install directory, here I will assume its in the default.

The next step is to add the necessary environment variables. In a terminal type in this. (Just type or copy it in one line at a time!)

Code:

echo "# CUDA stuff
 
PATH=\$PATH:/usr/local/cuda/bin
 
LD_LIBRARY_PATH=\$LD_LIBRARY_PATH:/usr/local/cuda/lib64
 
export PATH
 
export LD_LIBRARY_PATH" >> ~/.bashrc

Like the toolkit installer says, if you run a 32 bit version you must leave out the 64 part.

Next we install the SDK. In a terminal type in the following.

Code:

chmod +x ./cudasdk_2.3_linux.run
 
./cudasdk_2.3_linux.run

You dont need to be a superuser to install this.

First you get asked where you want to put the files, and where the CUDA toolkit was installed. (Check that this dir is the same as the one you installed it in, even if it says it located it. The dir need to be the same and not have additions of nvcc or the like!)

Last we need to compile the SDK files. In a terminal type (I assume default install dir)

Code:

sudo apt-get install gcc-4.1 g++-4.1

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.1 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.1 
 
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.4 40 --slave /usr/bin/g++ g++ /usr/bin/g++-4.4

cd NVIDIA_GPU_Computing_SDK/C
 
make

Now it should unpack everything succesfully. You may get a lot of warnings during the process, but these can safely be ignored.

Once it is done you can test that everything does in fact work by going into

Code:

cd NVIDIA_GPU_Computing_SDK/C/bin/linux/release/
