what is difference ssh.net vs ssh.net-netconf

[peter2145]

1. My program is doing netconf communication. (me is netconf client)
   1-1. When I use 'ssh.net-netconf', all of them(connect/sendreceieve ) success.
   1-2. When I use 'ssh.net', only connect success.
   what difference?

2. I need host key algorithm "ecdsa-sha2-nistp256". But netconf package has just rsa, dss.
   How can I add "ecdsa-sha2-nistp256" algorithm without ssh.net package?

The SSH.NET-NETCONF package is a fork of this one, with (only) the following changes:

develop...declspec:SSH.NET:develop

That could explain why it works.

@Rob-Hague I'm not familiar with netconf at all. I see what was change in this fork, but for now, I don't know what it does. I need more time to get to know this. Unless @Rob-Hague you know what this is about.

                var xpath = "/nc:hello/nc:capabilities/nc:capability[text()='urn:ietf:params:netconf:base:1.1']";

                _usingFramingProtocol = ServerCapabilities.SelectSingleNode(xpath, nsMgr) != null
                    && ClientCapabilities.SelectSingleNode(xpath, nsMgr) != null;

I am also unfamiliar with netconf

@peter2145 you may try the above change with the latest code here (which has ecdsa) and see if it works

[peter2145]

I using nuget Pkg 'SSH.NET-netconf'.
How Can I Use the latest PKG?

[peter2145]

Also, Is there anything for adding file "ecdsa-sha2-nistp256" algorithm?
I don't want to use nuget PKG 'SSH.NET'.

[Rob-Hague]

@peter2145 you should download the code, make the changes to NetConfSession.cs and build it. Then you can add a project reference and see if it works

[peter2145]

@Rob-Hague
I confirmed that it is operating normally.
The parameters of SendReceiveRPC() change depending on the _usingFramingProtocol variable.
I think parameter is problem.

Please reflect the above code in the SSH.NET package.

Thanks for checking. There is actually a similar change in PR #946 which seems to also fix the issue.
