timeout of the RGS Receiver to reduce RGS Receiver disconnection. Additionally, the RGS
Sender timeout might need to be increased too. See
Network settings on page 36 for further
details.
●
When connecting to a Linux remote computer, the PAM authentication dialog displayed by the
local computer does not appear long enough to enter the user’s credentials such as username
and password—This is likely caused by the RGS Receiver’s dialog timeout value being too
small. See the section
Network properties on page 82 for further details on setting timeouts. The
user should first check the RGS Receiver Control Panel to determine the Network dialog timeout
setting and adjust as appropriate.
●
When connecting to the remote computer, the authorization dialog is not displayed long enough
for the user to respond to it—This is likely caused by the RGS Sender’s dialog timeout value
being too small. See
RGS Sender properties on page 87 for further details on the property
Rgsender.Network.Timeout.Dialog. The default value for this property is 15 seconds.
●
When connecting to a Linux remote computer, the PAM authentication often fails—There are
several reasons why this might occur:
◦
PAM may be configured incorrectly.
◦
The user could be entering incorrect credentials.
◦
The timeouts are too short.
See
Installing the RGS Sender on Linux on page 20 to determine if PAM is correctly configured.
See
Network settings on page 36 for further details on setting timeouts. The user could try
increasing the RGS Receiver’s network dialog timeout as well as the RGS Sender’s error and
dialog timeouts to see if this helps. If this does not help and the user is convinced that the
timeouts are not being exceeded, then it is likely a PAM authentication configuration problem.
●
The Remote Display Window is not updating and appears to be hung—This is most likely
caused by a network disruption. You can adjust the warning timeout to get notification when this
occurs. You can also adjust the error timeout to disconnect and dismiss the Remote Display
Window sooner. The default warning timeout is two seconds. The default error timeout is 30
seconds. See
Network settings on page 36 for further details on setting the RGS Receiver
timeouts.
●
Increasing the RGS Receiver error dialog timeout doesn’t appear to have an effect and the RGS
Receiver still disconnects—This is likely caused by either:
◦
A network failure resulting in detecting lost connectivity by the RGS Receiver (resulting in a
disconnected connection)
◦
The RGS Sender timeouts are shorter than the RGS Receiver’s timeouts, and the RGS
Sender disconnects the RGS Receiver.
It is not always the case that network error timeouts are honored. A network error timeout only
establishes an upper bound on the duration of retries before returning with an error. If the
computer determines that network connectivity is lost and an error returns by the network stack
to the RGS Receiver, then the connection will disconnect sooner than the error timeout setting. If
the RGS Sender’s timeout values are shorter than the RGS Receiver’s, the RGS Sender may
close the connection sooner than the RGS Receiver, disconnecting the RGS Receiver. If the
issue continues, consider increasing the RGS Sender's error timeout value. See
Network
settings on page 36 for further details on setting timeouts.
