I really don't recommend using radutmp. And if you use sql, there's no need to use checkrad. Simultanous check is done using simple queries. > >> Reflash the NAS so that it has a firmware which supports this feature. > which feature(s)? RADIUS accounting, SNMP, finger, or rusers? Your If you use sql, you only need the NAS to send accounting. In my setup (pretty large deployment), we only check sql records to see whether a user is online or not. We don't check the NAS whether the user is ACTUALLY online, since checking the NAS directly can be slow. If you REALLY want to verify with the NAS, then the NAS should provide some kind of mechanism. Checkrad supports multiple vendors and multiple mechanism (read the file checkrad, it's documented). You could even modify it and write your own mechanism. > guidance here would really help so I can make sure I acquire > appropriate NAS' in the future. > Generally, is there any way to get simultaneous-use to work if a given > NAS doesn't send accounting packets to the radius server? 3rd party > software? I'd say don't bother. It MIGHT be possible if you write your own checkrad-like program and check ONLY the username, and the NAS can answer whether the username is online or not. -- Fajar - List info/subscribe/unsubscribe?
