5 years ago Hi,
firstly, your understanding of users is mostly correct except all the information is loaded form the system so if you have it configured that you can log in with root, you will also be able to use it for NETCONF sessions.
The reason you cannot connect has nothing to do with users (the errors would be different). Refused connection means that there is no one listening on the particular address/port you are connecting to. That is correct if you look at the last output of netopeer2-server, it has only configuration for authorized SSH keys, not for any endpoints. You have the module installed (ietf-netconf-server) so all you need to do is to configure it properly. You should have had the default configuration installed (netopeer2/server/stock_config.xml) but maybe you accidentally deleted it. In any case, if you write it into the datastore (using sysrepocfg --datastore=startup --merge=<path-to-stock_config.xml> --format=xml ietf-netconf-server, for example), you should be able to connect.

Hi,
I am trying to setup a netopeer2 server-client connection on my local machine using password from the following command on the cli: connect --host localhost . This , I believe, should try to login using the current user's username (unless I run sudo, which I am not ). I understand that logging in with 'root' user is not allowed as per linux policy but if I am not sudo, this should be possible right? However ,the cli prints a connection refused message while on the server side, I do not see any message received even though I have enabled all log levels. I wanted to understand how to debug these connection issues and where the username//password combinations are stored? Aren't these stored in ietf-netconf-server yang data files? Please find the attached logs:
