fiware

I am deploying FIWARE security GEs (i.e., Wilma, AuthzForce, Keyrock) in my computer. Security level 2 (Basic Authorization) is working well, but now I need security level 3 (Advanced Authorization) using XACML. Long story short, I want a tutorial of implementation security level 3. However, as far as I know, any tutorial or document about security level 3 does not exist. For now, I create my policy with PAP's API, and change 'custom_policy' option in config.js from 'undefined' to 'policy.js'. And then I create 'policy.js' file into 'PEP/policies', but don't change anything compared with its

Based on this answer about how to scale Orion Context Broker with load balancing https://stackoverflow.com/a/33068119/3706998 what should be the behavior of subscriptions and also notifications?

I have a subscription made to an entity's attribute to a MySql sink. The problem is that while I was testing my rest service to do a subscription if the data was not yet persisted, i made a ton of subscriptions. Now every time I do an update on the entity's attribute what happens is that the value is persisted a lot of times. Is there anyway of deleting a subscription without the subscriptionID? Yes, it is. First, you can list the existing subscriptions with the GET /v2/subscriptions operation (have a look to the draft NGSIv2 specification ). Once you have the IDs the unsubscribeContext

I am running Keyrock Fiware locally on my laptop in docker. I know this is working because I can visit http://localhost:8000 and http://localhost:8000/sign_up through my browser and they respond correctly. I am having trouble when it comes to creating API calls. I am trying to use Postman, but I am having trouble with obtaining an auth-token, which is required to make some api calls. Following this guide I am trying to create a POST request to http:/localhost:8000/oauth2/tokens This by itself doesn't seem to work and I need to add other information like grant_type=password&username=YOUR

I have an Orion context broker and i use cygnus(0.6) to send data to my cosmos account. Cygnus creates correctly the txt file with the data on my cosmos, but it does not create the tables for hive. I would query my data through an hive client. Is there a configuration paramater to set in cygnus.conf to do that? How can i solve? Ignacio Martin I found myself with the same issue and found the problem.

I was just wondering if there is any feature like RTMP in Kurento Media Server . I need it to stream my vod content . Any ideas ? anyhow RTP can be used for it ? Thanks Pawan There isn't a rtmp endpoint in Kurento, at least yet. But we have streamed content to a Wowza mediaserver using an RTP Endpoint with the last kurento development version. Maybe this can also work for you. 来源： https://stackoverflow.com/questions/27203318/how-to-do-rtmp-streaming-in-kurento-media-server
