C2G 52064 Single Port KVM over IP - Manual (Page 32)

Single Port KVM over IP
30 / 88
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). 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, 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
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.
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 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-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 such problems by adjusting the
keyboard of your remote system to the same mapping as your local one.
The Remote Console window always tries to show the remote screen with its
optimal size. That means it will adapt its size to the size of the remote screen
initially and after the screen resolution of the remote screen has been changed.
However, you can always resize the Remote Console window in your local
window system as usual.
Warning
In difference to the remote host system, the Remote Console window on
your local window system is just one window among others. In order to
make keyboard and mouse work, your Remote Console window must
have the local input focus.
