If you changed the status of the Ethernet Bridging feature, you will also need to power
the SV1115IPEXT on and off again to enable your changes.
Accessing the VNC Interface
There are three ways to communicate with the Server Remote Control unit in order to
control the host computer:
• Web interface: The integrated Web server includes a Java-based VNC client. This
allows easy browser-based remote control.
• Native VNC client: There are several third-party software programs that use the
standard VNC protocol, available in open source and commercial VNC clients.
• SSH access: By default, there is a standard SSH server running on port 22 (the standard
SSH port). Once connected via SSH, the VNC traffic is tunneled through the SSH
connection and encrypts the VNC session. Each method will be discussed briefly in the
following section. The type of encryption method or client used is not critical.
Web Interface
Using SV1115IPEXT’s web interface requires a browser, with cookies and JavaScript
enabled. To start the Java VNC client, login to the Web configuration interface and click
on the thumbnail of the desktop on the Home menu, or click on the Connect button,
located in the Main Menu.
You may need to upgrade Java support in your browser; however, most modern
browsers come with a version of Java that is compatible with this application. The Java
VNC client makes a connection back to the Server Remote Control unit over port 5900
(by default) or 15900, if encrypted. The encrypted connection is a standard SSL (Secure
Socket Layer) encrypted link that encrypts all data from the session, including the
actual video pictures.
Because Java is considered a “safe” programming language, the Java VNC client has some
limitations. Certain special keystrokes cannot be sent, such as “Scroll Lock” on the keyboard.
