hi everybody, i try to use the main_pool module but i meet some problems with it. I'm using radius server in order to authenticate vpn users connected on a cisco router i would like to assign fixed ip for each vpn users but when i use main_pool module in post-auth section, freeradius don't want to start with this error : Starting - reading configuration files ... Using deprecated naslist file. Support for this will go away soon. Module: Loaded preprocess Module: Instantiated preprocess (preprocess) Module: Loaded files Module: Instantiated files (files) Module: Loaded detail Module: Instantiated detail (detail) Module: Loaded IPPOOL rlm_ippool: Failed to open file /etc/freeradius/db.ippool: Permission denied radiusd.conf[561]: main_pool: Module instantiation failed. radiusd.conf[611] Unknown module "main_pool". radiusd.conf[609] Failed to parse post-auth section. what is the utility of db.ippool and db.ipindex ? and what is the right syntaxe for this both files ?
