Hi again guys, Sorry for my previous mail but I've had a mistake in my radclient command line !! echo "User-Password = tata, User-Name = tata, *Accounting-Status-Type = Start*" | radclient -x -d /usr/local/etc/raddb/ radius:1813 acct whatever => BAD echo "User-Password = tata, User-Name = tata, *Acct-Status-Type = Start*" | radclient -x -d /usr/local/etc/raddb/ radius:1813 acct whatever => GOOD Now the request works and I got accounting informations in the radacct table...but ONLY when I use radclient. It means that with my wireless client on windows XP which connect to the NAS (dlink DWL-2000AP+) it still doesn't work :-( So there's two ways : - This AP is not compatible at all and there no way to send accounting request..so I have to buy a new one (do you know a model ?) - This AP isn't compatible natively and there's a way to patch it or a way to send the Start request from other ways. Any ideas ? Thanks, Vincent It will work soon.... :-)
