values than normal steady-state timeouts. Authentication or authorization dialogs
often require more display time than standard messages and alerts due to their
importance. The RGS system supports alternate timeouts for user interaction to
separate them from operations such as sending graphics and audio content. This
enables usable authentication and authorization experiences as well as more
reasonable limits for standard messages and invocations.
The Receiver property, Rgreceiver.Network.Timeout.Dialog, (also available from the
Receiver Control Panel Network tab), limits the display of incoming and outgoing
query dialogs from the Sender requiring user input and interaction. Similarly, the
Sender property, Rgsender.Network.Timeout.Dialog, specifies from its side similar
limits for Receiver messages and queries. At startup the Sender uses the maximum
of either Rgsender.Network.Timeout.Error or Rgsender.Network.Timeout.Dialog
properties to define its networking timeout between the Sender and Receiver.
An example of dialog timeouts follows. If User A attempts to connect to User B's
desktop, an authorization dialog prompts User B. The RGS Sender prompts User B on
the Sender desktop asking for permission to connect User A to the desktop. The RGS
Receiver property Rgreceiver.Network.Timeout.Dialog limits how long the Receiver
waits on the invocation between the Receiver and Sender before returning failure.
The RGS Sender property Rgsender.Network.Timeout.Dialog limits the display of the
authorization dialog on the Sender. If either timeout expires without action, the
dialog exits and connection is denied by default or it defaults secure. If the Sender
timeout is shorter than the Receiver's timeout, the authorization invocation from the
Receiver to the Sender usually times out faster that the dialog times out, so the
authorization fails. If the Sender timeout is longer than the Receiver's timeout, the
authorization dialog expires faster than the invocation from the Receiver to the
Sender and the authorization still fails.
Another example follows for a different type of authentication. When a Receiver
connects to a Sender running a Linux or HP-UX operating system, the Pluggable
Authentication Module (PAM) authenticates the connection. In this case, the PAM
subsystem invokes a PAM conversation/callback function that results in the Sender
making invocations back to the Receiver to prompt the user with PAM message
dialogs. The Sender receives the responses. Typically the dialogs request a username
and password, but any message is possible. The timeout for the PAM
message/response dialog invoked by the Sender and displayed by the Receiver is the
Receiver's Rgreceiver.Network.Timeout.Dialog value.
The maximum of either the Rgsender.Network.Timeout.Error or
Rgsender.Network.Timeout.Dialog properties limits how long the Sender will wait for
a response. The Receiver controls the display time for the PAM message/response
dialog and the Sender controls how long to wait for a response from the Receiver. If
either timeout expires, the connection is denied by default or defaults secure if the
timeout is exceeded. If the Sender timeout is shorter than the Receiver's timeout,
then the authentication invocation from the Sender to the Receiver expires faster
than the PAM Authentication Dialog, resulting in a PAM authentication failure. If the
Receiver timeout is larger than the Sender's timeout, then the PAM authentication
dialog times out faster than the invocation from the Receiver to the Sender and the
PAM authentication still fails.
The property Rgreceiver.Network.Timeout.Dialog does not control all dialogs
displayed by the Receiver. For example, the authentication dialog for a Windows
Sender connection displayed by the Receiver for username and password does not
