RealPort configuration settings
Applications > Realport displays a page for configuring the RealPort application. Settings on this
page include:
 RealPort Settings
– Enable Keep-Alives: Enables sending of RealPort keep-alives. These keep-alives are
messages inside the RealPort protocol, sent approximately every 10 seconds, to tell
whoever is connected that the connection is still alive. RealPort keep-alives are different
from TCP keep-alives, which are done at the TCP layer.
Note that RealPort keep-alives generate additional traffic which may be undesirable
in situations where traffic is measured for billing purposes.
– Enable Exclusive Mode: Exclusive mode allows a single connection from any one
RealPort client ID to be connected only. If this setting is enabled and a subsequent
connection occurs that has the same source IP as an existing connection, the old existing
connection is forcibly reset under the assumption that it is stale.
 Device Initiated RealPort Settings:
– Index: An empty list means that no device initiated RealPort connections have been
configured
– Host or IP Address: The IP address or DNS name of the client to connect to.
– Port: The network port to connect to on the client. The default port for VNC servers is
8771.
– Retry Time: The amount of time in seconds to wait before reattempting a failed
connection to the client.
