However you can instantiate a new sql module in sql.conf: sql my-sql-acct { ... Accounting_stop_query =" MY Customized SQL query" } Then in you radiusd.conf accounting section: accounting { sql my-sql-acct }I tried this and freeRadius hangs at startup and says "my-sql-acct: Unknown Module". I added everything just like you said...
That's weird... It means that your my-sql-acct module definition wasn't read or accepted.
You should try to run radiusd with "radiusd -X" and carefully read the output: this will tell where the problem is.
If you can't find the issue, post the result of your "radiusd -X" (you could also add your radiusd.conf and sql.conf) and I'll have a look at it.
