Where can I get information on the error codes that I encounter while using VPN Client?

Refer to the Error Codes.

I get a message explaining temporary unavailability of resources. What does this mean?

You get such messages when you send data to a protected network (for example when you use FTP, Telnet, or ping). This is because a new security association is in the process of negotiation.

Retry the application to resolve this issue.

What should I do to get IKE debug logs?

In /var/log/messages, go to /etc/racoon/racoon.conf and comment out the log debug line.

How can I ensure that VPN Client is installed on my system?

Run the following command:

rpm -qi turnpike

The VPN Client GUI does not fit in the monitor, causing reading difficulties. What should I do?

Change your monitor resolution to 1024 x 768 pixels.
