Hello, I´m using freeradius-1.0.1-0.FC2.i386.rpm and freeradius-mysql-1.0.1-0.FC2.i386.rpm with Mysql for Authentication for my lan client . Now, I want also to check the MAC-Address of this Lan Client. Therefore I added the "Calling-Station-Id"-Attribute to the radcheck table. mysql> select * from radcheck; +----+----------+--------------------+----+--------------+ | id | UserName | Attribute | op | Value | +----+----------+--------------------+----+--------------+ | 1 | tala | User-Password | == | 123123 | | 2 | tala | Calling-Station-Id | == | 000d88522f1f | +----+----------+--------------------+----+--------------+ 2 rows in set (0.00 sec) Unfortunatelly, freeradius cannot validate this user anymore. Are there any config-files I have to change? or i use this attribut wrong i.am a beginner in radius and thanks in advanced . --------------------------------- Yahoo!
