Hi, Typically, FreeRADIUS would be using selects by using one value - %{Packet-Src-IP-Address}. I would like to know the secret it is using to communicate with the freeradius to compare on our user database. (the user actually generates these secrets and implement it into their NAS) Is there other ways to do it (even using other than secrets?) or do i have to depend solely on Packet-Src-IP-Address? I am doing more development than doing implementation myself and i am seeing all the secret values seemed to be transparent to the freeradius configuration itself (for building applications on top of it) Thanks, Muhammad Nuzaihan -- Taqi Systems 269-J Jalan Panji Kampung Chempaka, Kota Bharu, Kelantan 16100 Phone: +6097738657 Mobile: +60199788657 pub 4096R/4C77F88C 2013-04-06 [expires: 2015-04-06] Key fingerprint = 2FE1 87FA E775 2E05 CC0F B3F6 3CB7 C65F 4C77 F88C uid Muhammad Nuzaihan Bin Kamal Luddin <muhammad@taqisystems.com>
