Secure connections with Ultr @ VNC

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 vnc 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), that only authorized clients can connect to the server.

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) vnc 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.

VNC We check our PC / Mac Remoter

Increasingly we need to have access to the systems we have at home. Fortunately there are many software on the AppStore. Today we announce Remoter.

Remoter: Remote Desktop is an application, available on the AppStore, released a Universal version. With it, we can access both Windows PC to our vnc Mac
In fact, the vnc protocol is a protocol-platform: Mac OS X is already installed by default, while in Windows we have to install the server component.
Remoter is also very useful for accessing UNIX systems, also having the management of the SSH protocol.

Let’s see the features:

* Support to vnc;
* Support for SSH, Telnet;
* Support for iPhone OS 4.x onwards;
* Virtual Trackpad;
* Supports WOL, Bonjour, NetBIOS, and;
* Support for gestures of IOS.

Remoter: Remote Desktop is available on the AppStore for iPhone and iPod Touch at a price of 0.79 € and is localized only in English.

VNC : Check any PC remote access.

vnc (Virtual Network Computing) is a system by which we can remotely control any computer, so that if multiple PCs are connected to the same network or the Internet, we can work without problems even at a distance, using our mouse and your keyboard.

Just install the server application on your computer to be controlled and vnc the client (or viewer) on your PC, from which, indeed, we will check the host, introducing the corresponding IP address and setting a password to protect the connection.

With the free version of vnc we can already control the market of any operating system (Windows NT 4, 2000, XP, Server 2003, Linux, Solaris, HP-UX, AIX, …), with the fee including the latest Windows Vista , Server 2008, Windows 7 and Mac OS X.

Connect to your home PC from anywhere in the world with your laptop or any other computer, without complicated configurations, thanks to vnc.

Real vnc Windows systems in the hands of Mac

As I wrote in another post you can access your Mac remotely, but if you want to control your Mac from a Windows system?

One immediate solution is to use a famous software for the Microsoft world, Real vnc , this vnc application allows you to add the VNC protocol to Windows systems.
Real vnc I suggest you download the free version, the software is also available for GNU / Linux.

During installation, you can choose the modules to be installed, by default installs the server and the viewer,
a choice that I advise you to be able to make more operations possible.

After installation you can use the Viewer going to call Run vnc Viewer from the Programs menu / RealVNC / vnc Viewer 4,
to connect you just enter the IP address of the server and, after pressing OK, you will need to identify themselves with a password of your choice.

With the program Real vnc Viewer, you can also change the connection options,
in fact if you press the Options before you connect you can have different formats in configurations where you can change the behavior of the vnc viewer.
If you want a good yield of the service I advise you to double check the setting of the maximum number of colors and the data compression algorithm.

introduction vnc

(vnc stands for Virtual Network Computing) is a graphical system designed to access remote machines: protocol-based RFB (Remote Frame Buffer),
allows you to remotely control a machine. So, as guaranteed by the Remote Desktop feature of Microsoft Windows systems,
it is possible to act on a remote computer as if it were local, acting on your desktop (and managing the components)
through the use of mouse and keyboard.

The vnc vnc system is based on two distinct components. On the one hand you have the server,
need to be installed on your computer that you want to take remote control,
the other a client (or viewer) to be installed on the machine from which you want to access (and control) and remote.
You must also remember that vnc uses TCP ports, with the standard configuration, ranging from 5900 to 5906 (corresponding to as many remote screens).
The following steps illustrate how to establish a connection between a remote computer that uses Ubuntu 10.04 “Lucid Lynx”
(which will act as the viewer) and a remote machine (in this case, on a LAN) with Microsoft Windows XP SP2.
