Tor Browser Bundle


What is the Tor Browser Bundle (TBB)?

The Tor software protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, it prevents the sites you visit from learning your physical location, and it lets you access sites which are blocked.
The Tor Browser Bundle lets you use Tor on Windows, Mac OS X, or Linux without needing to install any software. It can run off a USB flash drive, comes with a pre-configured web browser to protect your anonymity, and is self-contained. Learn more.

Quick videos on how to use TBB

Download Tor Browser Bundle

To start using the Tor Browser Bundle download the file for your preferred language. This file can be saved wherever is convenient, e.g. the Desktop or a USB flash drive.
Tor Browser Bundle for Windows (version 2.3.25-8)
Tor Browser Bundle for Intel Mac OS X 10.6 and higher (version 2.3.25-8)
Tor Browser Bundle for Linux (version 2.3.25-8 (32-bit), 2.3.25-9 (64-bit))
ALPHA: Tor Browser Bundle alpha versions for Windows (2.4.12-alpha-2), Linux 32-bit (2.4.12-alpha-2) and 64-bit (2.4.12-alpha-2), and Intel Mac OS X 10.6 and higher (2.4.12-alpha-2).
See our instructions on how to verify package signatures, which allows you to make sure you've downloaded the file we intended you to get. Also, note that the Firefox ESR in our bundles is modified from the default Firefox ESR

Mac OS X instructions

Download the file above, save it somewhere, then click on it. Mac OS X will automatically unarchive it and you will have a TorBrowser application in your chosen language (for example, TorBrowser_en-US.app). Click the TorBrowser application to launch Vidalia. Once Vidalia connects to the Tor Network, it will launch TorBrowser.
Screenshot Mac OS X bundle

Linux instructions

Download the architecture-appropriate file above, save it somewhere, then run one of the following two commands to extract the package archive:

tar -xvzf tor-browser-gnu-linux-i686-2.3.25-8-dev-LANG.tar.gz

or

tor-browser-gnu-linux-x86_64-2.3.25-9-dev-LANG.tar.gz

(where LANG is the language listed in the filename).

Once that's done, switch to the Tor browser directory by running:

cd tor-browser_LANG

(where LANG is the language listed in the filename).

To run the Tor Browser Bundle, execute the start-tor-browser script:

./start-tor-browser

This will launch Vidalia and once that connects to Tor, it will launch Firefox. Do not unpack or run TBB as root.

Windows instructions

Extraction

Download the file above, and save it somewhere, then double click on it. Click on the button labeled "..." (1) and select where you want to save the bundle then click OK (2). At least 80 MB free space must be available in the location you select. If you want to leave the bundle on the computer, saving it to the Desktop is a good choice. If you want to move it to a different computer or limit the traces you leave behind, save it to a USB disk.
Click Extract (3) to begin extraction. This may take a few minutes to complete.
Screenshot of
    extraction process

Usage

Once extraction is complete, open the folder Tor Browser from the location you saved the bundle.
Double click on the Start Tor Browser (4) application (it may be called Start Tor Browser.exe on some systems.)
The Vidalia window will shortly appear.
Screenshot of
    bundle startup
Once Tor is ready, Tor Browser will automatically be opened. Only web pages visited through Tor Browser will be sent via Tor. Other web browsers such as Internet Explorer are not affected.
Once you are finished browsing, close any open Tor Browser windows by clicking on the Close button (×) (6). For privacy reasons, the list of web pages you visited and any cookies will be deleted.
Screenshot of
    Firefox
With the Tor Browser Bundle, Vidalia and Tor will automatically close.
To use the Tor Browser Bundle again, repeat the steps in "Usage".
Remember that Tor anonymizes the origin of your traffic, and it encrypts everything inside the Tor network, but it can't encrypt your traffic between the Tor network and its final destination. If you are communicating sensitive information, you should use as much care as you would on the normal scary Internet — use HTTPS or other end-to-end encryption and authentication.

Comments and suggestions

The Tor Browser Bundle is under development and not yet complete. To discuss improvements and submit comments, please use the tor-talk mailing list.

What is Tor and why do I need it? To learn more about Tor, visit the Tor Project website.
What is in the Tor Browser Bundle? It contains Tor, Vidalia, a modified Firefox ESR, and Torbuttoni ( design) (version details).
How can I make my own bundle? To download the source code and learn how to build the bundle yourself, read the build instructions.
Tor Browser Bundle is partially based on Mozilla Firefox ESR

Ping: nos informa del estado de un host. Es necesario permitir paquetes icmp para su funcionamiento.

Ping -t: se hace ping hasta que que pulsemos Ctrl+C para detener los envíos.

Ping -a: devuelve el nombre del host.

Ping -l: establece el tamaño del buffer. Por defecto el valor es 32.

Ping -f: impide que se fragmenten los paquetes.

Ping -n (valor): realiza la prueba de ping durante un determinado numero de ocasiones.

Ping -i TTL: permite cambiar el valor del TTL. TTL seria sustituido por el nuevo valor.

Ping -r (nº de saltos): indica los host por los que pasa nuestro ping. (máximo 9)

Ping -v TOS: se utiliza en redes avanzadas para conocer la calidad del servicio.



TRACERT: INDICA LA RUTA POR LA QUE PASA NUESTRA PETICION HASTA LLEGAR AL HOST DESTINO.

ARP: MUESTRA Y MODIFICA DATOS DE LA TABLA DE TRADUCCION DE DIRECCIONES IP A DIRECCIONES MAC (TABLA ARP)



Arp -a (también -g): muestra la tabla ARP para cada uno de los interfaces

Arp -s (dir_ip) (dir_MAC) [dir_interfaz]: añade una entrada especifica a la tabla ARP. Si hay varios interfaces de red, añadiendo al final la direccion IP del interfaz, lo añade en la tabla correspondiente a ese interfaz

Arp -d (dir_ip) [dir_interfaz]: elimina una entrada especifica de la tabla ARP. Se pueden usar comodines en la direccion IP. Si hay varios interfaces de red, añadiendo al final la direccion IP del interfaz, lo elimina de la tabla correspondiente a ese interfaz.

Route PRINT: muestra la tabla completa de rutas

Route ADD (red_destino) MASK (mascara_destino) (puerta de enlace) [METRIC metrica] [IF interfaz]: Añade una ruta. Con el modificador -p (route add -p ...) hace la ruta persistente, de manera que se mantendra aunque se reinicie el equipo.

Por Cardoomx TFTP lo que hace es transferir archivos de un sitio a otro se necesita un servidor en uno de los dos ordenadores y funciona mas o menos asi.

TFTP [-i] host [GET
PUT] origen Funciona tanto en redes locales como por internet ( abriendo puerto claro ). A mi parcer es una utilidad muy muy buena cuando conectas por shell a un pc para administrarlo. Claro esta que no todo el mundo lo usa con buenos fines.



comando netsh

se puede utilizar entre otras cosas para cambiar los parametros de la red desde linea de comandos...



ejemplo de funcionamiento:

netsh interface ip set address name=LAN source=static addr=192.168.1.4 mask=255.255.255.0 gateway=192.168.1.1 gwmetric1

netsh interface ip set dns name=LAN source=static addr=80.58.0.33

netsh interface ip add dns name=LAN addr=80.58.32.97
