Re: Is it possible to connect to a Linux box that is just running SSH2 for a Test?

[carl roberts]

BTW,

In the test case where I pass the path to the private key via the certificate option, there is no pass phrase, therefore, I am not passing a password option.

I have tried creating a Client instance to just talk to SSH2 on Linux

I have tried using the username/password and using the username/
certificate and in both cases the code fails.

When I try the username/password, I get this:

When I try the username/certificate, I get an authentication error
like this:

In both cases, putty works.

What is it I have to do to get the Client program to work?

Or, will this kind of test not even work as I am just trying to test
against a regular SSH2 server on Linux and not a NetConf Server?

Thanks,

You cannot just connect to a regular SSH server; you need to connect to a NETCONF server.

If you take a look at the NETCONF RFC, you will see that it uses the "netconf" subsystem over SSH, a regular server would have not support for that.

Are there any good netconf servers/simulators that I can use for trying out.

Gautam,

You can download Yuma from http://www.yumaworks.com/yuma

It's an open source Netconf server/agent.

NetconfX has ben tested against it.

Hi,

Any free netconf servers/simulators for testing.
