Hello, I have some scripts that do some sync tasks when freeradius start accouting: Like this: created module, named 'sysnotify' with this: exec sysnotify { wait = no program = "/ondasys/system/sysnotify %{User-Name:-Nenhum} %{Framed-IP-Address:-Nenhum} %{Acct-Status-Type:-ERR} %{Acct-Session-Id:-ERR} %{NAS-IP-Address}" packet_type = Accounting-Request } and, instanciated at preacct block: preacct { acct_unique sysnotify } it´s working fine, but i need to optimize this, because this scripts are running in Accouting-Start, Accouting-Stop and Interim-Update .. How i can catch ONLY Start and Stop events ? Regards ! -- Sds. Alexandre Jeronimo Correa Sócio-Administrador Onda Internet www.onda.net.br IPV6 Ready !
