If it was working fine, but now it isn't, the chances are that CatTools is reaching its internal 'timeout' limit for the 'get config' command.
1) Can you confirm first of all that your device paging prompt looks like: --- more ---
2) Can you also confirm that the CatTools device type set for this device is still 'Juniper.NetScreen.Firewall'.
Thank you for your feedback.
I just found where was the problem, the Mail server wasn't properly configured. I configured the correct IP @ and it's working again :)
Many thanks & kind regards
