Hi guys In the meantime I got a little clue about the rest module and got it (almost) working. One last / simple step is missing; I need to send the MAC address in the format aa:bb:cc:dd:ee:ff instead of aa-bb-cc-dd-ee-ff. We call the function rewrite_calling_station_id in /etc/freeradius/sites-available, but for the REST API call we need it with colon as delimiter? Is there an easy way to replace chars in strings in unlang / freeradius? Regards Dominic Von: "Stalder, Dominic (ID)" <dominic.stalder@unibe.ch> Datum: Montag, 23.

So far, with simple check on a fixed Calling-Station-Id, it works. Now I would like to implement an GET API call to our IPAM (Infoblox) in the following format: https://xyz.domain.com/wapi/v2.11.3/record:host?network=172.25.8.0/21&mac=aa... First things first, I enabled the rest module: ln -s ../mods-available/rest /etc/freeradius/mods-enabled/rest 1. With the default configuration, I get the following output: rlm_rest (rest): Opening additional connection (0), 1 of 32 pending slots used rlm_rest (rest): Connecting to http://127.0.0.1/ rlm_rest (rest): Connection failed: 7 - Couldn't connect to server rlm_rest (rest): Opening connection failed (0) rlm_rest (rest): Removing connection pool 2. When I comment the corresponding “connect_uri” like mentioned in the rest module comment, I get the next error: # rlm_rest will open a connection to the server specified in connect_uri # to populate the connection cache, ready for the first request. # The server will not start if the server specified is unreachable. # # If you wish to disable this pre-caching and reachability check, # comment out the configuration item below. # connect_uri = http://127.0.0.1/ including configuration file /etc/freeradius/sites-enabled/control-socket /etc/freeradius/mods-enabled/rest[188]: Reference "${..connect_uri}" not found Errors reading or parsing /etc/freeradius/radiusd.conf As I stated, I would like to start very simple and go step by step from there because I have absolutely no clue how to implement the requested API call so far. But if anyone has a hint to “overcome” this error and maybe has a simple example of an GET API call, I would appreciate.
