proxy and other questions

[dodekaeder]

Hi.

I've Problems with the proxy test. All other tests pass 100% while proxy fails all the time. Seems to be some more general unix related problem, cause the proxy is not permitted to use the coap-client, but I don't know to solve this issue.

AND

As my first question already revealed, I'm not an expert but trying my best. To do this there would be some community very delightful. Is there any?

btw: Thx for your great work. I think CoAP is a relatively young but attractive protocol and for know I allready saw some implementations which where nice but a unix based implementaion is just awesome!

Hi,

Since the proxy uses ipv6, you need to make sure that the following line appears in /etc/hosts

::1 ip6-localhost

Let me know if that works. If not, send me the output of the proxy test.

Keith.

The problem occurs when the proxy tries to open a socket to the server. Are you running all 3 of the test_coap_server, test_proxy_http_coap and test_http_client applications?

Just to understand.

The proxy calls the client. The clients output is the only one I can't see in this test but it works like in the other tests, right?

My Unix imagination just reaches the possibility of a system task which isn't authorized by the owner, like starting the client.

You should check which one of the return statements is being executed in the coap_client_dtls_create. One of them is returning -1. This corresponds to the 'Operation not permitted' error message.

The URI module used by the HTTP/CoAP proxy now supports IPv6 addresses, e.g. coaps://[::1]:12436/resource
