Troubleshooting network timeouts

The network timeout properties of RGS Receiver and RGS Sender provide a way to handle network

disruptions. Although TCP/IP is reliable, it does not guarantee network packet delivery. Possible issues include

the following:

●

Network over-subscription, resulting in congestion and packet loss

●

CPU utilization by other processes and tasks, starving the TCP/IP network stack

●

Incorrectly congured or malfunctioning network switches, routers, and network interfaces

See below for a list of timeout-related issues and solutions.

The remote display window repeatedly dims and displays a connection warning message.

Cause Solution

There are frequent network disruptions between RGS Receiver

and RGS Sender.

If the notications are occurring too frequently, increase the RGS

Receiver warning timeout value.

The remote display window dims, and RGS Receiver disconnects and displays a connection error, but you can connect again

immediately.

Cause Solution

The length of the network disruption exceeded the error timeout

value of either RGS Receiver or RGS Sender.

NOTE: This could also occur if RGS Sender was stopped

unexpectedly.

Increase the error timeout value of RGS Receiver, RGS Sender, or

both.

When connecting to a Linux-based sender, the PAM authentication dialog on the receiver does not display long enough for

credentials to be entered.

Cause Solution

The RGS Receiver dialog timeout value is too low. Increase the dialog timeout value of RGS Receiver.

When connecting to the sender, the authorization dialog is not displayed long enough for the user to respond to it.

Cause Solution

The collaboration request timeout value of RGS Sender is too low. Increase the collaboration request timeout value of RGS Sender.

The remote display window is not updating.

Cause Solution

A network disruption occurred, but the warning and error timeout

values of RGS Receiver are set too high.

Decrease the warning and error timeout values of RGS Receiver.
