VNC & HTML5: Display the remote desktop via a web browser with Guacamole
Using machines (virtual or not) remote, I often have to use VNC to access the desktop, sometimes you need a graphical environment. I learned a few days ago Guacamole, program that provides access to the vnc desktop via a standard Web browser that supports the HTML5 canvas tag, however.
The program works very well and quickly, the only thing a bit ‘complicated is the installation. First you need to install tomcat6. For the heart that makes the whole thing is a Java application that sends the information to the browser to display the desktop. We perform the installation:
Now that the web server is installed, you must download the program from this link. After unpacking the archive, what we are facing are some xml files (configuration files) and a war (archive containing the application itself). This is the installation procedure:
The files are now installed on the webserver but you must configure them. In particular, / etc/tomcat6/guacamole-users.xml find the pair user: password is requested that we open the application, it is not the vnc password to a password but its application. In the file / etc/tomcat6/Catalina/localhost/guacamole.xml instead contains the VNC server information:
The parameters of interest are the three listed above, and are filled with data from the VNC server. In particular, to calculate the door, it is necessary to obtain the number virtual desktop started (: 1 for example) and add it to 5900. In this case, then the server to which we connect to is: 1. To start a new vnc server of course type the command:
If this is your first time you start up a vnc server, you will be prompted for a password for access (insert is not required), what must be included in the file guacamole.xml. Now restart the web server:
and Colleghiamoci application via our browser (compatible with an eye to use the HTML5 CANVAS tag, Chromium / Chrome or Firefox are fine 5) using the link:
There will first be prompted to authenticate the program. If you have not changed the username is guacamole-users.xml ‘Guacamole’ and password ‘changeme’, of course is strongly recommended to change it. After entering the password of the VNC server (if of course has been set):
There you now have access to your vnc server is vnc much simpler, in fact, by setting such as the Tomcat port 80, you can access the remote desktop in peace even in the presence of proxy not too lenient!

Reviewed application Droid VNC server for Android by Julyano87
Another great review by our staff Julyano87, now we describe an application to remotely control your PC from our smartphones. Thanks Julian, your contribution is always very valuable and your reviews always well done, neat and very detailed!
I leave you with his words:
“The remote control is always a perfect way to help all those operations that can not be performed directly on vnc our vnc computers. There are, in computer science literature, many methods and programs that perform this operation very well, lately, thanks to the development in the technology of mobile phones, has become possible to manage our home PCs even by them. If the utility of this operation has always been undisputed, surely it is also useful to the opposite operation: the remote management of our mobile phones via PC. In this regard, today I’m going to review the application:
NB To use this application you must:
1) own the rights to the root
2) Have installed the java plugin in our browser
3) Install a vnc client (in the review I used RealVNC Viewer, a free application available at this address)
-Just open the application you will be facing a screen composed of a minimalist backdrop and two large buttons that have the function to start and stop the vnc server. It ‘s all we need. Tappiamo on “Start Server” and move on

In VMWare ESXi you can connect to each virtual machine via a VNC server
already present in the core of our ESXi, specifying a password, a port for
each of the VM and logically enabling the vnc service.
Procedure (from Carry out each of the VM for which you want skilfulness this feature):
1) Make the Power Off Virtual Machine.
2) Connect to the server via SSH or using the VMware ESXi Hidden Console (alt + F1) if you are physically on the server.
3) Posizionari inside the following path: / vmfs/volumes/datastore1/CentOS 64bit (in this case we are performing the operation on a CentOS 64-bit).
4) Edit the file. Vmx, in this case called: CentOS 64bit.vmx (ESXi provides you with “you” as an editor).
5) Add at the end of this file the following lines of code:
remotedisplay.vnc.port = “port”
remotedisplay.vnc.enabled = “true”
remotedisplay.vnc.password = “password”
Replace the values ”Ports” (to use a different port each VM) and “password” with those you deisiderati. example:
remotedisplay.vnc.port = “5901″
remotedisplay.vnc.enabled = “true”
remotedisplay.vnc.password = “esxiVnCView”
6) Exit vnc and save (in vi press Esc and type: wq).
7) Carry out the Power On the VM.
Use a vnc client to connect to the vnc port of your virtual machine by inserting ESXi server IP (not the specific VM) and the specified port (different for each VM)) in the file. Vmx.

How to remotely connect to a screen Meego using VNC (x11vnc)
After several trial and error, I think I discovered a simple and reliable solution to remotely access the screen Meego.
First of all I want to clarify that I am no expert on X11. Different solutions may be available and / or better, but this solution is simple and seems to work well. It is likely that the configuration can be further improved. If so, please add these improvements vnc to this article. Meanwhile, the procedure presented below helps to quickly connect with a remote screen to the device Meego.
The solution that I offer in this article works with a destination Meego netbook Atom Embedded installed on a system. It’s also been tested on some other destinations Meego on various hardware platforms. I assume that it works with any device Meego, even if it is not guaranteed.
The solution uses a utility called x11 vnc that was written by Karl Runge, and that “allows a person to remotely view and interact with real X displays (for example, a screen corresponding to a monitor, keyboard and mouse real ) with a vnc viewer. In this sense, the role that plays in Unix/X11 Win vnc is to Windows. “The main function of this utility is offered by remote access to the physical screen, controlled by X11su vnc, is a different function than an X11 virtual screen. For detailed information on this utility, read the full page of Karl.

iTeleport, a VNC client for iPhone OS, updates itself by introducing voice commands to launch applications
iTeleport is an application available on the App Store that allows vnc to connect remotely to your Windows PC or Mac has been recently upgraded by introducing an important new features for users with an iPhone 4S that, from now on, will start programs with simple voice commands.
Recently, developers have iTeleport updated with support for authentication through the Lion and the username and password of the OS from Apple. On this iTeleport is updated again, coming to version 5.2 which will allow owners of an iPhone 4S launch applications vnc simply by speaking their name preceded by the word “Launch”. Once you start the application and the successful vnc connection with the standard keyboard will appear with a field of IOS for the composition of the text and the dedicated button to start the vnc Syrians. Normally dictating commands to the Syrians, they would be transcribed in the field of composition, but the developers seem to have iTeleport discovered a way to launch applications without transcription: for we do not do anything else, for example, say out loud “Launch iTunes” to successfully launch iTunes. The quality of the voice recognition seems to be the same as that which would occur with the Syrians; therefore very high quality.

VNC – Virtual Network Computing
vnc is an acronym that stands for Virtual Network Computing: is a program that allows you to control a remote computer through any type of network.
In very simple terms vnc does is to connect two computers directly configured appropriately giving the ability to control, by one of two machines,
the remote computer as if you were physically sitting in front of it, used if you want the GUI , mouse,
and everything that you can access with the privileges of the user with which you connect to the remote machine.
vnc was initially developed by Olivetti before being sold to research laboratories in Cambridge by AT & T,
but the mass distribution of the program only came with the birth of the project RealVNC was born as an offshoot of the original project and then be developed in a manner autonomously.
Today there are several versions of vnc such as the previously mentioned RealVNC, TightVNC, UltraVNC, etc..
The program is available for all types of operating systems and for almost all types of hardware architectures.
The implementation of vnc environments for GNU / Linux is based on Xvnc, a server software that does not connect to a real X display, but uses a dummy X11 session to which multiple clients can connect.
It should be noted that X already offers the ability to natively run a program on a computer displaying the windows in the X servant of another computer. vnc, unlike this implementation,
allows connection to a GNU / Linux, even from another machine that does not have an X server installed, for example, a PC with Windows. In addition to any vnc client is great is a little more vnc than a few hundred KB (can be conveniently contained in a floppy disk) and requires a configuration very easy to do.
x11vnc is the version of ‘vnc‘ for GNU / Linux I chose for my install Debian GNU / Linux and where you will find a guide to using the base in these pages.

A protocol, not a program vnc
We begin our discussion vnc by clarifying that vnc is not a program. Rather, we are talking about a protocol,
or a “language of communication” that must be implemented (or “understood”) by the specific software you want to provide access capabilities through this technology.
Originally created at Olivetti & Oracle Research Lab (ORL), source code and specifications of Virtual Network Computer vnc have been been publicly released,
promoting the proliferation of parallel implementations (all but compatible) more and more equipped.
Among the most significant, we might remember that the Real vnc , a company founded by the original developers, TightVNC,
an open source project aimed at narrow-band connections, and Ultra vnc , which also comes under a free license but with many additional features compared to competitors .
Precisely because of the larger dowry that comes with Ultra vnc , specifically in the article we will refer to this implementation.
As already mentioned, however, the various implementations of vnc are all compatible with each other: this means that a client has, for example,
UltraVNC will connect to a remote computer which could perform RealVNC or vice versa.
