passing data from PAM module

[Ivan Grover]

Hi,
My PAM application uses remote authentication module pam_radius_auth.so for
authenticating users from remote servers. There can be several remote
servers. In this case, can any one please suggest me the best way to gather
information on several remote servers such as
-- server reachability, (kind of returning  array saying server 1 is
reachable, server 2 is unreachable)
--  do they run radius service
...etc

I am trying to use pam_get_env pam_set_env for the above. Please advise, if
this is not the proper way.

I looked at pam_set_data, but i think this cant be used in PAM application.


Best Regards,
Ivan
