2.3 The Remote Console
The Remote Console is the redirected screen, keyboard and mouse of the remote host system
that IP console controls. See the figure below.
The Remote Console window is a Java Applet that tries to establish its own TCP connection to
the IP console. The protocol that is run over this connection is neither HTTP nor HTTPS, but
RFB (Remote Frame Buffer Protocol). As default, RFB tries to establish a connection to TCP
port number 443. Your local network environment has to allow this connection to be made. So,
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 console 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 desired 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 networking environment.
2.4 Main Window
Starting the Remote Console (see section 2.3) 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 locally 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 link to which you use to connect to the IP console.
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. For instance, if you use a German administration system, and your host system uses a
US English keyboard layout, special keys on the German keyboard will not work as expected.
Instead, the keys will result in their US English counterpart. You can circumvent such problems
by adjusting the keyboard of your remote system to the same mapping as your local one.
