Hi,
Tech calls in and say that he can't get an appliance working in the field. I ask him what secret he's using and the IP address of the appliance. I want to be able to be locally logged onto the radius server and use radtest/radclient/rad???? to be able to query radius asking "If I was IP, and I gave you SECRET, would you authorize me?".
So I want to be on 1.2.3.4, but say I'm on 3.4.5.6 . Right now, If I say I'm on 3.4.5.6, it still wants the secret for 1.2.3.4 .
you want to spoof the source address? tricky. one 'easy' way to do this would be to create a local VPN/GRE tunnel on the linux box under which you could emulate a remote link.
configure freeradius to also listen on that virtual address, run the radclient with the destination being the end point of the VPN - the linux routing tables would then come into play. you'd have to reconfigure the VPN end addresses etc each time to emulate an outside world link...but it would work.
Not worth it. All I'm looking to do is get programatic confirmation that the ip/secret combination in the field is correct. Since this is an appliance, not an OS, I don't have access to radtest on the appliance. To have someone start setting up VPN/GRE/etc is more hassle than its worth. I just have to tell the tech to RTFD closer. I was just hoping I could put together a local form on a webserver that could shell out to a script to make the test. We'll just have to suffer. :) (Or ask the manufacturer to include a utility in the "diagnostic" section) Thanks, Tuc
