When creating a new protocol session, it fails with a Configuration Error.
It's likely the context for the given protocol doesn't contain enough information for a session to be created, or it's just wrong. Use the protocols:context command to register a context with corrected information. Check that the URI contains the user/password, host, schema, etc... Concrete context information, however, depends on the underlying protocol implementation.
When trying to start a new resource, it fails with the following error: "The subsystem request failed".
The netconf subsystem for ssh connections is not set in the router. You can find the problem description and it solution at http://jira.i2cat.net:8080/browse/OPENNAAS-238
