This link logs out the current user and presents a new login screen. Please note that an
automatic logout will be performed in case there is no activity for half an hour.
5.4 The Remote Console
General description
The Remote Console is the redirected screen, keyboard and mouse of the remote host
system that PS/2 IP-KVM switch controls.
Figure 5-5. Remote Console
The Remote Console window is a Java Applet that tries to establish its own TCP connection
to the PS/2 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 PS/2 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.
