After using FR 1.0.5 for testing for a while with a FR+MySQL configuration, I found out the hard way that documentation is not a pet project of FR. The only up-to-date documentation I found so far is reading the source code for hours, days, weeks ... There are lots of features I could not find anywhere in any kind of documentation, but in the source code, e.g. positional parameters for the SQL nas table. Or you can use the IP or domain name within the nas table for the 'nasname'. What happens to dynamic DNS addresses? etc.... Anyhow, it is a nice piece of software, working most of the times very well! Additional guidance, a wiki or ... could be extremely helpful for the project ... maybe it even exists somewhere. I found my way around, but I am kind of stuck when it comes to the accounting records. Sometimes I simply do not get a stoptime and therefore the session is supposed to be still online. I can then take maybe the idle time, add it to the last startime and see if it makes 'sense'. I had 4+ records with empty starttime for a nas. All I like to do for instance ... - User got 24h (or other time period) allocated - When session ends an updated record for the next session time could be generated - When user logs in again, the remaining session time will be granted But what happens when radacct does not get the stoptime for the last session? Anyhow, is there anything, anywhere (up-to-date) where I can find further information? Going through ever source file is quite a time consuming act. Anyhow, Open Source is best ... I can apply changes without requesting a license change ;-) And where can you directly communicate with the developers ... Thanks! G.
