I've pushed some more code which sanity checks the dynamically expanded configuration items. e.g. for the "detail" module, you can do: filename = ${radacctdir}/%{%{Packet-Src-IP-Address}:- ... In v3.0.4 and earlier, typos in the "filename" would result in run-time errors. Which are hard to debug. :( For future versions, these typos are caught when the server loads: ./raddb/mods-enabled/detail[34]: Failed parsing expanded string: ./raddb/mods-enabled/detail[34]: /usr/local/var/log/radius/radacct/%{%{Picker-Src-IP-Address}:-%{Packet-Src-IPv6-Address}}/detai... ./raddb/mods-enabled/detail[34]: ^ Unknown attribute This is much friendlier to administrators. It doesn't cause any issues, and it means that typos are caught quickly. As a result of this change, I've fixed a few typos in the SQL queries. Alan DeKok.
