Help everyone! I'm working with Freeradius 3.0.15 And trying to implement authentification by MAC and NAS-Port and NAS-IP-Address and files module. The solution i found by now is to assign key variable in mods-available/files files authorized_macs { key = "%{Calling-Station-ID}-%{NAS-Port}-%{NAS-IP-Address}" usersfile = ${confdir}/authorized_macs } And in authorized_macs have string 00-24-54-05-8D-CB-5002-192.168.100.2 It works. Is there a neat way to do it? Check attributes separetelly. For example: authorized_macs contents: 00-24-54-05-8D-CB Cleartext-Password := 00-24-54-05-8D-CB NAS-Port == 5002 NAS-IP-Address = 192.168.100.2 Reply-Message = "Device with MAC Address %{Calling-Station-Id} authorized for network access" I appreciate any help) -- Best regards, Dmitri
