computer determines that network connectivity is lost and an error returns by the network stack to
the Receiver, then the connection will disconnect sooner than the error timeout setting. If the
Sender’s timeout values are shorter than the Advanced capabilities Receiver’s, the Sender may
close the connection sooner than the Receiver, disconnecting the Receiver. If the issue continues,
consider increasing the Sender's error timeout value. See
Adjusting Network timeout settings
on page 127 for further details on setting timeouts.
6.6.2 Dialog timeouts
RGS supports dialog timeouts, which specify how long user interactions between the Local Computer
and Remote Computer are allowed to take. The two dialog timeout properties are:
Receiver dialog timeout property—This property specifies the maximum time that the
Receiver (Local Computer) will wait for a dialog response from the Remote Computer in response
to a message sent to the Remote Computer. It also specifies how long dialogs initiated by the
Remote Computer will be displayed to the user on the Local Computer.
Sender dialog timeout property—This property specifies the maximum time that a message,
originating from the Receiver, will be displayed on the Remote Computer. It also specifies how
long the Remote Computer Sender will wait for a dialog response from the Receiver.
For example, assume that a local user is attempting to connect to a Remote Computer. Assume,
furthermore, that another user is already logged into the Remote Computer (this person is therefore the
primary user). The Sender will prompt the primary user for authorization to connect the local user to the
Remote Computer. The duration of this prompt is set by the Rgsender.Network.Timeout.Dialog property.
The Receiver property Rgreceiver.Network.Timeout.Dialog limits how long the Receiver will wait for a
response from the Remote Computer before returning failure.
If the Rgsender.Network.Timeout.Dialog timeout expires without action by the primary user, the Sender
dialog exits, and connection is denied by default. If the Sender times out, the Receiver will also time out
(based on its Rgreceiver.Network.Timeout.Dialog property) because no authorization reply will be
returned by the Sender.
In the previous example, the dialog was displayed on the Remote Computer. An example of a dialog
being displayed on the Local Computer follows. When a Receiver connects to a Sender running Linux,
the Pluggable Authentication Module (PAM) on the Sender attempts to authenticate the connection. In
this case, the PAM subsystem invokes a PAM conversation/callback function to the Receiver, causing
the Local Computer to prompt the user with a PAM message dialog. The dialog typically requests a
username and password. The timeout for the dialog on the Receiver is controlled by the
Rgreceiver.Network.Timeout.Dialog property. If this timeout expires without the local user entering a
username and password, the Receiver will remove the dialog.
NOTE: The property Rgreceiver.Network.Timeout.Dialog does not control the duration of 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 have an associated timeout since it is
not an incoming message from the Sender to the Receiver. This dialog will be displayed indefinitely
until the user responds "OK" or "Cancel" to its requests
The Receiver dialog timeout property, Rgreceiver.Network.Timeout.Dialog, can be set using the
Receiver Control Panel as shown in
Figure 6-22 Receiver Control Panel on page 129, and has a
default value of 15 seconds (15,000 milliseconds). This property can also be set using the
rgreceiverconfig file and from a command line.
