Hello everybody, I simply and correctly setup my ubuntu linux box to use freeradius authentication; actually the problem is that I'm not able to use radius accounting. I think that I correctly setup my radius server to use sql as accounting mode but the radius server neither receives accounting packets from the client (I see it starting the server with the -XXX option). The only "accounting" thing that it's saving in the sql db is the post auth section that inserts a line for a correct authentication response. on the client side I only modified the pam - gdm configuration file that is #%PAM-1.0 auth requisite pam_nologin.so auth sufficient pam_radius_auth.so auth required pam_env.so readenv=1 auth required pam_env.so readenv=1 envfile=/etc/default/locale @include common-auth auth optional pam_gnome_keyring.so account required pam_radius_auth.so @include common-account session required pam_limits.so @include common-session session optional pam_gnome_keyring.so auto_start @include common-password whitch step have I forgotten? what's wrong? thank you for your help, sub
