Probably easier if someone who can speak French answers for you as you'll understand better. But, I'll answer for now.
That message means you need to enable identd.
Try again. If the same problem, then you probably have a firewall or a router. In that case, you need to forward (open) port 113 in the firewall/router. http://www.portforward.com
has great information for how to do that with just about anything you might have.
Usually, identd kills are unset immediately, so you can fix it and get back in right away. If you have problems after doing everything else, wait a day or two and try again just in case the server sets a timed ban for identd.
