Free Open Source Computer Lab Monitoring Software Using vnc

Background:

I teach in a PC computer lab. As a teacher, I need to help and observe all of the computers at the same time. For Mac OS X there is a great piece of software called Apple’s Remote Desktop. On the teacher’s computer monitor it presents a live scaled-down view of all of the computer screens in the lab. The teacher can watch all the students doing work and when necessary, focus in on one computer and move that computer’s cursor with their own mouse.

For PC/Windows labs there is a program called vnc which allows one computer to watch and control another computer. Unfortunately, viewing is intended to be only one at a time. But, the great thing about vnc is that it is a free open source project, which means anyone can use it and improve it.
Viewer & Servers:

There are two parts to vnc, a Server program and a Viewer program. The Server program shares a computer’s screen over a network. The Viewer program connects to a server and redraws the remote computer’s screen on it’s monitor. Because the software is split this way, watching multiple computers at the same time just entails creating a bunch of (small) vnc Viewers within a single program. No modifications need to be made to the Server and minimal changes to the Viewer.

I wrote VncThumbnailViewer in Java to make use of TightVNC‘s java vncviewer. The VncViewer code is pretty modular, so creating a vnc program that contains vncviewers wasn’t too complicated.

For all directors is very handy to have a remote access to their systems. Ultr @ vnc, which I introduced here, is a great utility with many features, geared to Windows users. The approach is “a la PCAnywhere”, unlike the Windows remote desktop connection. Species may be useful in some cases: for example, when the other side there is someone who should see what we do, or when you want to interact with the shell of Lotus Domino (and do not want to use the live console).
Since Ultr @ vnc allows full access, the security implications must be understood and properly managed.

Ultr @ vnc communicates “clear”, which means that communications are not encrypted by default. In theory, an attacker who had access to communication between a server and a client Ultr @ vnc, might steal session data.
There are two main implications to be considered, using Ultr @ vnc in an environment where security is important:

* Encryption – Encrypted communication make the interception of data much more dificult
* Authentication “strong” – Provides a mechanism to determine with greater certainty (more than just the password), vnc that only authorized clients can connect to the server.

already present in the core of our ESXi, specifying a password, vnc 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 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.

Hello everyone as the subject …..
I noticed that Vodafone and Wind (I only tried them) actually do not allow exercising this option.
All this serves very well into the nat that is local, so applications can not be discussed but when the handheld starts in his regular gprs acquiring ip vnc does not act
here are my steps

1) Installation remora dyndns to create a host of power;
2) Installation of mobile vnc server in order to be able to manage the office and provide assistance to the handheld (in my case a Trimble TSC2)

vnc works where the doors are usually 5900, 5800 and perhaps 5500

making a port scanner on the ip of the handheld connected to GPRS or HSDPA are closed,
I now ask you if this is a solvable problem:), maybe with a different operator from wind and vnc vodafone
Thanks to those who want to enlighten me

Real vnc, the company that developed the popular vnc remote control software, has implemented IOS systems manageable by their programs.

The company that owns the software for Virtual Network Computing has officially announced the implementation of IOS systems manageable.

Recall that vnc allows you to remotely manage multiple operating systems. It is widely used in large companies to provide remote support to users.

What does this kind of implementation? RealVNC has said that you can manage our iPhone / iPod through a car stereo via the touch screen display.

Currently there are several radio that manage our iPod / iPhone, but the control is done directly from the vnc car. And still you do not have full control dell’iDevice.

With vnc, the screen would be displayed on the display thus having complete access to your iPod or iPhone.

Hello everyone,

now playing around and trying a few things about Android I stumbled upon a project on google code that bodes well.

The project, open source, allows the installation of a binary on your system Android, which, when launched, opens port 5901 for the reception vnc connections.

For those who do not know what vnc:

The Virtual Network Computing (or vnc) is remote control software and are used to administer your remote computer by installing a vnc server on your machine and setting a proper password VNC client allows you to receive an image of the screen and provide input keyboard and mouse to the server computer.
In fact, we can manage the server computer from another location, like your physical vnc computer.

The vnc server is a convenient way to manage many computers on the network (Internet or intranet and are) using a single workstation.

They are often used to remotely control servers that have neither monitor nor keyboard.

We begin by clarifying that with vnc does not mean a particular program, but a category of programs that allow remote control of a computer.
The acronym stands for Virtual Network Computing vnc and the common feature is the use of such software RFB protocol, Remote Frame Buffer.
In this article we use a vnc server on a Linux system on a Windows system. The information provided will be helpful, however, in any case configuration.

The scheme is simple: on the one hand to control the computer on which to install the vnc server, the computer controlling the other hand using the client component,
the so-called viewer. The two machines can be connected via a private LAN or through the public Internet.
In the latter case the work is likely to be more burdensome for the need to configure other devices such as firewalls and routers.

If the workstation client establishes a connection to the server will see the desktop of the remote machine in a window of the program.
We can act on it directly with your keyboard and mouse as if we were our physically sitting at the computer.
The cool thing about this is that the operating systems involved in communication can be different: Linux, Windows or MacOSX.
We could control a Windows 2003 server on vnc our Linux box, or, conversely, a Linux server from a Windows XP station.

If you read the article on vnc client free for all major operating systems, you’ll quickly realize that Mac OS X does not offer the wide selection they offer other operating systems (Linux in particular), and that in fact most of the software outstanding are paid.

Well, what (perhaps) did not know is that Mac OS X has everything you need to connect to a vnc server and therefore does not require third-party applications (except special needs, that is).

Those jokers Cupertino fact have taken steps to integrate the default vnc client, but they thought it best to leave it in the shade, away from prying eyes. However, given the usefulness of the application to see how the case has cast it as necessary vnc and put on display between applications. All this after having admired this
