I wish I wouldn't have a timeout though .. anyhow
The only thing with "Access-Accept" in the radius.log file I see is the 
result of
[sql]   expand: INSERT INTO radpostauth (username, pass, reply, 
authdate) VALUES ( '%{User-Name}', 
'%{%{User-Password}:-%{Chap-Password}}', '%{reply:Packet-Type}', '%S')

How would those look ?

PPPoE radius # grep -i "Acct-Status-Type" radius.log
Yells nothing .. for noone .. I might not have it enabled ?

I'm using rp-pppoe with the radius plugin

I think it's doing it right ..
