Single port KVM over IP switch
Figure 5-4. Remote Console
The Remote Console window is a Java Applet that tries to establish its own TCP connection
to the IP-KVM switch. The protocol that is run over this connection is neither HTTP or HTTPS,
but RFB (Remote Frame Buffer Protocol). Currently, RFB tries to establish a connection to
port number 443. Your local network environment has to allow this connection to be made, i.e.
your firewall and, in case you have a private internal network, your NAT (Network Address
Translation) settings have to be configured accordingly.
In case the IP-KVM switch is connected to your local network environment and your
connection to the Internet is available using a proxy server only without NAT being
configured, the Remote Console is very unlikely to be able to establish the according
connection. This is because today's web proxies are not capable of relaying the RFB
protocol.
In case of problems, please consult your network administrator in order to provide an
appropriate network environment.
5.4 Main Window
Starting the Remote Console opens an additional window. It displays the screen content of
your host system. The Remote Console will behave exactly in the same way as if you were
sitting directly in front of the screen of your remote system. That means keyboard and mouse
can be used in the usual way. However, be aware of the fact that the remote system will react
to keyboard and mouse actions with a slight delay. The delay depends on the bandwidth of
the line which you use to connect to the IP-KVM switch.
With respect to the keyboard, the very exact remote representation might lead to some
confusion as your local keyboard changes its keyboard layout according to the remote host
system. If you use a German administration system, and your host system uses a US English
keyboard layout, for instance, special keys on the German keyboard will not work as
expected. Instead, the keys will result in their US English counterpart. You can circumvent
