Hi,
I am trying to configure ssh/pam to use freeradius as one of the authentication
sources on a C6 box.
I have freeradius running on a separate box with 2 factor authentication.
Using the radtest utility, I can successfully authenticate. My problem is that
I do not understand how to configure pam to use radius as an auth source and
be sure I am not opening a security hole in my systems.
While googling, I have found several howto's that talk about how to do this
using the pam_radius utility but the examples do not match what is found in
/etc/pam.d/sshd.
What I would like to accomplish is the following:
1. Allow logins using ssh keys.
2. If that fails, Allow login via radius.
3. if not on the local network disallow login via a regular user name and
passwd.
I think 3 might be able to be accomplished via a match statement in sshd.conf
but
I am not sure.
Does anyone know how to do this in a secure way?
If I start modifying the pam.d configuration files, how can I be sure I am not
opening up a security hole?
Regards,
