libssh: ssh_userauth_none always returning SSH_AUTH_ERROR

In my ssh client I am using ssh_userauth_none before calling ssh_userauth_list(). But it always returns SSH_AUTH_ERROR. When I try to find out the reason for error using ssh_get_error() it says Socket error: disconnected.

I have used the same code on other linux machine (Ubuntu), it works fine. But when I try it on an embedded machine which is based on CentOS linux, it always fails with the error -SSH_AUTH_ERROR.

Am I missing any fields in ssh_config file which makes none authentication to work?.

Or is it related to some username/path issue?

it looks like you got disconneced from server. What are the DEBUG3 level logs on the remote server? – Jakuje Sep 11 '15 at 08:57
Why are you calling `ssh_userauth_none`? Just in case it works? Does it fail when you connect from the embedded machine or to the embedded machine? – Martin Prikryl Sep 11 '15 at 09:11
I am running both ssh server and client on embedded machine – Banu Prakash Sep 11 '15 at 09:39
one more observation on server side, I see that "ssh_handle_key_exchange" is getting failed – Banu Prakash Sep 11 '15 at 11:58
