Hi, I've got another query to do with this issue. I'm trying to follow up running an external script that could feasibly update a control value within freeradius. It's working fine to push the variable outwards, and recording that passed variable to a file using the bash redirect >> , however I've not been successful updating a control attribute. A reply attribute works, for example "Reply-Message := \"hello fred\"" but (in this example) My-Local-Integer := <new value> doesn't seem to get back. I've got Input_pairs = control And Output_pairs = control in the exec module I'm using (have I misunderstood their usage?) and am assigning the Reply-Message attribute the value that should be returned from the script using update reply { Reply-Message := "%{control:My-Local-Integer}" } so I can see what's happening to the control value which seems to be working as radtest shows the reply message attribute but doesn't show that it's been updated. The output of freeradius -X does produce Exec-Program-Wait : value-pairs: My-Local-Integer := <newly set value> but the value never makes it into the control attribute Perhaps I'm doing something I can't do with control attributes, or am just doing it wrong, which is much more likely. I've followed the example of the exec-program-wait script in the docs folder and it works as stated before for reply attributes, just not control ones. Thanks again Andy
