Dear all: i managed to install a Debian Lenny with freeradius and i would like to use Mysql to clients and users data, because i think its better than radius plain text files; and i would like to use a webadmin to reporting and management too. but, i'm confused. my installation is "zero", i mean, just "make install" and something like that. 1- i dont know if i have to configure manually the "clients.conf" file and it will be automatically written on mysql database or conversely, i would write my data on mysql manually and those data will be automatically writted on text files? maybe , i think there are independent of each. 2- I have a 3Com Total control making dial-up authorizations; now, i need to use radius to pppoe ,for aaa. i think i will use the HiperARC card, so i think my model in clients.conf isn't "tc", it is usrhiper, right? 3- I'm very, very confused in this : who does bandwidth limitation for a user? i.e.: "Joe" must have 128Kbps of traffic limitation. pppoe server does (3Com)? or radius does somehow? or maybe freeradius send parameters to 3com hiper arc to set it ? Thanks in advance. Carlos. Note.- someone stated "i had enough". I would like to say (in my poor english): documentation isn't better of world, but is better of freeradius, and FREEradius it's the better of all Free-Radius software. and its free. it is enough! Thanks for responding every time.
