It should be done by NAS. For example PPPoE and PPTP have lcp packets, If no response for some time from client to NAS then NAS decides that session is down and sends acct-stop packet to radius server. Radius server sets the corresponding record to SQL session table. Or there is another method: depending on NAS type radiusd can connect to NAS and check activity of user session directly on NAS - this is more reliable source of information. See radcheck.pl.

Yes, this is /usr/sbin/checkrad. Sorry for mistake. You should read this script ... Radiusd can be down or unrichable or packet can be loss. If You have NAS one of this type You can specify this type in clients.conf (nastype = cisco). After than radiusd should use /usr/sbin/checkrad to check simultaneous logins. But if You have a situation when NAS has opened working session and radiusd has no records about it in session table You can get double login. AFAIK in this case radiusd will not do simultaneous check at all. But it should not happen -- when radiusd goes down suddenly the records in SQL session table should be stay like opened sessions. And after radiusd starts again it thinks that that sessions are active :-), in this case radiusd will use checkrad if nastype is configured to check his SQL records. Moreover if You will connect simultaneously very fast (faster then Your SQL can handle queries) and without using checkrad then You will get simultaneous logins too. This is because there is no any transaction is SQL schema or no other method to make single unique login attempt in a time for SQL can see them like separate tries.

Here we go again 1. add datetime column at the end of radacct table (name it for example last_update_column) 2. edit queries in dialup.conf (for 2.x FR) or sql.conf (for 1.x FR) so every update will update this column to (for example update radacct set ........, last_update_column = NOW() ). Now you will have the correct time when was the last update for specific session. 3. write php, perl, shell or any other script which you can start with cron and check if there is any active sessions (acctstoptime = null or acctstoptime = 0) which last update was X minutes ago. For example, X can be 11 minutes and you can set up your NAS to send updates every 5 minutes. This means that you can have at least 2 updates before you close session with cron script. This is not the only way to solve this problem but it works with all FR version, and it doesn't depend on your NAS(es). Also, this isn't ideal solution because if your NAS goes off and on again before you received stop packets, all users will need to wait X minutes before they can connect again. (there are no updates so last_update_column will be unchanged and the cron script will close all sessions after X minutes) Spacelee wrote:

my nas client is pptp and ppp, how can i set pptp to send updates every 5 minutes? On Tue, Jun 1, 2010 at 7:13 PM, Marinko Tarlac <mangia81@gmail.com> wrote:
