Please help me. Do I understand correctly that you want each unique IP address logged only once in the entire log ? I don't know of any mechanism that can do this out-of-the-box. Maybe if you use ulogd, log to a database and then run a sql job to it at regular intervals to remove duplicate source IP's you can achieve this. But that would be ugly. ;-) Gr, Rob
