AWS IoT Device Tester for AWS IoT Greengrass V2 Proxy Configuration

Question

I am using IDT v4.5.3 with Greengrass nucleus v2.5.5. Both of the device running IDT and device under test is behind a network proxy. Now my test suite failed at mqttpubsub test case. How can I apply proxy config ?

I am getting the following error log from mqttpubsub/greengrass-test-run.log

ConnectException:          "java.net.ConnectException"

Answer

Thanks for answering. Greengrass have no problem running on the device using manual installation with proper proxy configuration.
The problem we are having here is AWS IoT Device Tester (IDT) for Greengrass V2 doesn't provide any arguments for us to set proxy config and caused IDT to failed the test suite.

Hi,

Thanks for reaching out. From the provided logs, it looks like the root cause was a connection timeout so it is likely that there was an endpoint that the device was unable to reach.

You can follow this page on our [documentation](https://docs.aws.amazon.com/greengrass/v2/developerguide/configure-greengrass-core-v2.html#configure-network-proxy) to configure the network proxy for your Greengrass device. This [page](https://docs.aws.amazon.com/greengrass/v2/developerguide/allow-device-traffic.html) contains some additional information regarding the endpoints that the Greengrass device will need to reach in order to perform as expected.

Please follow the above documentation to apply proxy config. Let us know if you may have any other queries.

Hi,
I have the same problem here, trying to run the IDT on a Ubuntu PC which is behind a company proxy.
Here is the log
-----

time="2022-10-27T12:23:27+08:00" level=info msg=1) [Guice/ErrorInCustomProvider]: ModuleProvisionException: UnknownHostException: www.amazontrust.com
-----
Adding the proxy as parameters inputs (-Dhttp.proxyHost=xxxxx -Dhttp.proxyPort=yyyy) in ./tests/GGV2Q_2.4.0/suite/mqtt/mqttpubsub/test.json did not help.

Disassembling RegistrationContextModule.class where the access to www.amazontrust.com seems to happen, I saw this line:
L9:     getstatic Field java/net/Proxy NO_PROXY Ljava/net/Proxy;
I have no knowledge about Java but is seems that the proxy is hard coded to NO_PROXY.

So: do you confirm my understanding that there is no way to configure the proxy through the JAVA flags, and if so, do you have any plan to add the proxy setting support to the IDT?

Thanks!
