Error with get-schema format not supported when connecting to netopeer2 server #1595

Closed kurimusityu closed 1 day ago

kurimusityu commented 1 week ago

Hi, When the netopeer2 client connects to the netopeer2 server, the module is loaded from the server via get-schema, but this request fails with an unexpected reply. Is there anything you can tell us about this factor?

We can see the following log sequence.

The version of the netopeer2 server we are using is 2.1.49 and the version of the netopeer2 client is 2.0.69.

thank you

I am quite sure this is an incompatibility between used libyang and libnetconf2 version. When updating, please update all the libraries and netopeer2 to a specific compatible version, the latest releases are always compatible.

kurimusityu commented 1 week ago

I will look into the compatibility of libyang and libnetconf2. Thanks.

By the way, the server-client connection is established after such an error message appears. At this time, get-schema works, is this normal?

Yes, an explicit CLI get-schema executes different code than the internal one in libnetconf2.

kurimusityu commented 1 week ago

libyang version was 2.1.111, libnetconf2 version was 2.1.28.

I will update these to compatible versions and try again. Thanks.

kurimusityu commented 1 day ago

I found that libnetconf2 v2.1.28 is compatible with libyang v2.1.30. Therefore, we built libyang v2.1.30. As a result, when a netopeer2 client connects to a netopeer2 server, the module is successfully loaded from the server via get-schema.

Thanks. I will close this issue.
