thanks for the answers.
Köszi Gergő a gyors választ Neked is.
I have found all that things yet. But I would like to get the host name before radius authentication. I mean as soon as the dchp part gave ip to the client I want to store client information.
I went through the interesting part of the code and my plan is to receive the required information in the cb_dhcp_request(...) part.
Here I have a connection yet I can use for this.
And do you mean that I can simple implement the following steps?
*create radius message to fill that attributes
*add attributes to that (client ip and host name or anything else)
*call radius-req to send the radius message via the given connection
*call radius response to receive the date
*get attribute from that to save them into a file or store everywhere else
It seems be the perfect solution (or at least good) as I think. Please tell me what do you think about my plan? Is it good direction?
ps. I see in the chilli.c the cb_radius_auth_conf fnc that if radius is enabled the code asks for domain name. but it is not called if I have only dhcp connection as I checked the log file

These features are indeed implemented, and work well. Use the
--dhcpradius option (and compile with --enable-dhcpradius, which is the
default) and use --macauth.
Attributes in chilli C are defined in src/radius_chillispot.h
