Using the Terminal Interface via Serial Port
The terminal interface you can access via the serial port permits the configuration of the
basic settings of the SVxx41HDIE. While not intended to be a substitute for the Web
interface, it does allow you to configure some of the same functions. The menu list below
describes the options that can be modified through the terminal interface.
Note that you must use the
W
option to confirm and apply any changes made before you
exit the terminal session.
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 SVxx41HDIE’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.
This client software requires the use of Java 2 (JRE 1.4) to enable features like wheel
mouse support. Sun Microsystems’s Java site, www.java.com, is an excellent resource to
ensure your browser and operating system are updated accordingly.
