Resumen a mostrar NetBeans se refiere a una plataforma para el desarrollo de aplicaciones de escritorio usando Java y a un entorno de desarrollo integrado (IDE) desarrollado usando la Plataforma NetBeans.
Antes de instalar netbeans tenemos que instalar tres paquetes, estos son la edición estándar de Java Runtime Environment (JRE) 6 y Java Development Kit (JDK) 6, paquetes necesarios para que netbeans pueda ejecutarse. Para instalar los paquetes usamos el gestor de paquetes synaptic, que es muy fácil de usar y viene preinstalado en la distribución de ubuntu. Se puede conseguir en el menú menú Sistema – Administración – Gestor de paquetes Synaptic.
Contenido completo Para instalar los paquetes solo tenemos que abrir synaptic, en la caja de texto de búsqueda rapida escribimos java6 y en los resultados de abajo marcamos para instalar el siguiente paquete:
sun-java6-jdk
luego de seleccionarlos le damos en el botón aplicar
y en la nueva ventana también le damos aplicar
Después de descargar java nos aparece un asistente de instalación preguntando si estamos de acuerdo con los términos de licencia
Si estamos de acuerdo seleccionamos la casilla y luego le damos en el botón Forward para seguir la instalación.
Al terminar la instalación Synaptic nos mostrará la siguiente ventana:
Ya con java instalado procedemos a Descargar e instalar NetBeans 6.7. lo primero que hay que hacer es ir a la pagina de descarga de NetBeans http://www.netbeans.org/downloads/
Allí aparecen todas las descargas para el ide, lo primero que hay que hacer es cambiar la pagina de descarga al español, esto lo logramos seleccionando español en la parte de lenguaje de IDE.
Luego de esto hacemos clic en el botón download de la columna que queremos instalar, aparece una ventana con la descarga del archivo, el cual guardaremos en un lugar donde después lo podamos encontrar.
Ya con el paquete descargado solo tenemos que hacer clic para ejecutarlo dándole clic al archivo, la ejecución a veces es algo lenta así que hay que esperar un poco, cuando al fin se ejecute aparecerá una ventana con el asistente de instalación.
En ella, los paquetes que se van a instalar, en mi caso aparecen todos los paquetes disponibles. Si todo está correcto hacemos clic en siguiente para continuar con la instalación.
En la siguiente ventana nos pregunta si aceptamos los términos de licencia, si lo aceptamos seleccionamos la casilla y le damos en siguiente.
Ahora pregunta donde queremos instalar el IDE y la ubicación jdk, en mi caso lo dejaré así como está y recomiendo no mover nada. Sin mas que hacer le damos clic en siguiente
Ahora el asistente nos nos muestra la configuración básica por defecto del servidor glash Fish, no necesitamos hacer ninguno cambio así que le damos en siguiente, siguiente y luego instalar.
Después que termina solo tenemos que dale en terminar y ya tenemos instalado nuestro IDE y listo para ayudarnos a crear lo que nos de la gana en los diferentes lenguajes que soporta.
Si tienen problemas o correcciones la pueden colocar en los comentarios, se las recibiremos con mucho gusto.

It’s so wonderful! The new version GNS3 release! As far as i know, many guys are using the GNS3.
From the release documenation, there are a lot of improvement in this update, GNS3 official statement:
Hi everyone, GNS3 v0.6.1 is released! this is a minor release that brings some improvements and bug fixes. Nothing really new but now we have a solid base to start making new features. Also the GNS3 binary version for Windows has been repackaged to include python 2.6 and Qt 4.5.1 dlls. A binary version (.app) for MacOS X should be released soon.
Improvements:
Copy an inserted image in the project’s working directory and update its path in the .net file.
Prevent auto-generated interface notes to be recorded in the .net file.
Display an error msg box if a working directory can’t be used by an hypervisor.
Check if a hostname has already been used when creating a new node.
Warn to use manual links when a user select a NM-16ESW module.
Check if GNS3 is running on a Windows 64 bits OS in order to choose the correct path to Putty.
Check IOS and working directories paths when creating new nodes and throw a warning to the user if something is wrong.
Button to edit project settings.
Fixes:
Prevent notes to be deleted when typing the delete key while editing.
Prevent NM-16ESW modules to be removed from routers when using Ethernet/FastEthernet links.
Tooltips update when starting/stopping/suspending routers.
Bug with Qt 4.5 on selected filter when openning a project (getOpenFileName)
99MB limit for pcmcia disks.
Unicode errors with TMP env variable on Windows.
AttributeError: value of `chassis’ must be of type string.
Merge correct config paths when loading a .net create on a different platform.
Cisco SDM (Security Device Manager) is a commonly used administrative tool for configuring Cisco Routers out of the box with limited command line knowledge. While many network engineers prefer configuring Cisco devices via command line, some users enjoy the simplicity of a web configuration GUI. In this lab you will configure the prerequisites for the Cisco SDMinstallation and then install Cisco SDM by the Windows SDMinstallation wizzard.
SDM is typically frowned upon by the majority of the network engineering community but SDM does have several benifits. Cisco SDM allows for individuals to deploy, configure and monitor in real time Cisco Devices with limited or no command line knowledge. This allows for users with limited or no Cisco experince to maintain a Cisco router via a web configuration GUI. SDM utilizes HTTPS for secure web management.
Lab Prerequisites:
This Lab requires the Cisco SDM setup files which are available for download at the Cisco Software Center. (Check Downloads for a link to the SDM Demo)
An established telnet, ssh or console session to a supported Cisco device.
A ethernet interface configured with an IP address and subnet to allow for remote SDMinstallation via the SDM setup wizzard. (You should be able to ping the device from a computer)
Lab Objectives:
Configure IP HTTP & HTTPS Server and use HTTP Local Authentication.
Configure a username and password with level 15 privileges. (Username:cisco / Password:cisco)
Configure the virtual terminal lines to authenticate locally and accept Telnet & SSH Sessions only.
OPTIONAL: Enable local logging to support the log monitoring function.
Install Cisco SDM (Security Device Manager) via the Windows Setup Wizzard.
Lab Steps:
Step 1: First you need to download the SDM zip file from the Cisco Software Center, extract the ZIP file to a folder on your desktop. (ftp://ftp.cisco.com/pub/web/sdm/)
Step 2: You need to configure the router prerequisites to accept the SDMconfiguration from the SDMInstallation wizzard from within windows. Enable HTTP Server, HTTPS Server and configure HTTP authentication to authenticate to the local user database, this is done in global configuration mode.
Router(config)#ip http server Router(config)#ip http secure-server % Generating 1024 bit RSA keys, keys will be non-exportable…[OK] *Apr 3 15:24:35.450: %SSH-5-ENABLED: SSH 1.99 has been enabled. Router(config)# *Apr 3 15:24:40.675: %PKI-4-NOAUTOSAVE: Configuration was modified. Issue "write memory" to save new certificate Router(config)# Router(config)#ip http authentication local
Step 3: Now create a username with level 15 privileges
Step 5:OPTIONAL: Enable local logging to support the log monitoring function.
Router(config)#logging buffered 52100 warning
Step 6: Click the SDM setup executable in the folder which you extracted the SDM zip file(s) to. Click next once the Cisco SDMInstallation Wizzard appears.
Step 7: You must accept Cisco’s License agreement to use this software. Once you accept click next.
Step 8: Move the bullet down to the "Cisco Router" selection and click next.
Step 9: Input the IP address of the router as well as the username and password which you created that has level 15 privileges. In you have followed this lab then the username and password configured is cisco / cisco. After you click next, The SDMInstallation Wizzard will attempt to connect to the router, if you receive an error then you may have incorrectly configured the SDMInstallation prerequisites or have a firewall blocking the installation.
Step 10: Once the Installation wizzard has successfully connected to the route you will be given the option to install the typical or custom packages. Select the Custom Bullet and click next.
Step 11: Check mark the "SDM: Install Cisco Router and Security Device Manager." option and click next.
Step 12: Now you are ready to install Cisco SDM onto your Cisco Device. Clck "Install" to start the installation.
Step 13: Once the installation has finished you can check the "Launch Cisco SDM" if you wish to start the SDM immediately, if not then you can type the routers IP address into a web browser and launch SDM that way.
