okay - just a big range will help you

the single line log can be chaged to give more details...but the detail
logs give more information - like explicit NAS-IP-Address etc - so if
you want more detail, use the detail module....not the linelog.

alternatively, use SQL to hold the clients and have each one defined...
you can then use dynamic_clients so new entries can be added on the fly
without server rebooting
