I have added some additional radcheck options using checkval module. For example I have several NAS Servers, and I've defined which user from which NAS allowed to login. Now I want to know is it possible to configure Freeradius in a way, that when it rejects a user, it prints a custom error in log file? e.g: user test is not allowed to login via NAS 1.2.3.4, it is configured to login via 4.3.2.1 .

if(NAS-IP-Address != "1.2.3.4") { custom_error reject } where custom_error is linelog instance writing your custom error into the log. Ivan Kalik Kalik Informatika ISP
