For all directors is very handy to have a remote access to their systems. Ultr @ vnc, which I introduced here, is an excellent 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).
Ultr @ vnc since it 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 dificile
* Authentication “strong” – Provides a mechanism to determine with greater confidence (more than just the password) so that only authorized clients can connect to the server.
You will learn to use Ultr @ VNC MSRC4 with the plugin, plug-in for Microsoft Windows Crypto API Ultr @ vnc
Ultr @ vnc is distributed through an installation package very easy to use. MSRC4Plugin is a single file that is copied into the program folder.
On the server side:
After copying the file, you should see the plugin available in the “DSM Plugin” server properties Ultr @ vnc. Select “Use” and then “Config”. Fix the 4 boxes by entering the correct path, if your operating system is not in English. Choose the level of complexity of your key (you can safely use 128-bit), and press the button “Gen Key”. While you’re set the access pasword.
In the program folder you will find the key you just created, make a copy on a secure means, eg. a USB memory.
Client side:
Even here when using the plugin and configure it for the correct paths. Copy the key that you previously saved in the program folder.
At this point MSRC4Plugin encrypts the communication between the server and the client using the key contained in the file that you generated and transported. Since the same key is required at both ends of the link, was also obtained from stronger authentication “strength” of the single password. Only those in possession of the correct key can connect.
Occurred, especially during the first links that the plugin is really working: the vnc client from the toolbar, select “Show Status Window”, and verify that you are connected via “MS RC4 Plugin”.
