Thanks Alan! Now it creates the files but only when I issue /sbin/radiusd as root, it can create/access the idx and db files. When I start it issuing (as root) /etc/init.d/radiusd start, it fail: Wed Apr 18 06:41:59 2012 : Info: Loaded virtual server inner-tunnel Wed Apr 18 06:41:59 2012 : Error: rlm_ippool: Failed to open file //etc/raddb/db.mp.nl.sycada.com_pool: Permission denied Wed Apr 18 06:41:59 2012 : Error: /etc/raddb/modules/ippool[90]: Instantiation failed for module "mp.nl.sycada.com_pool" Wed Apr 18 06:41:59 2012 : Error: /etc/raddb/sites-enabled/default[383]: Failed to load module "mp.nl.sycada.com_pool".
