Is there a way to tell JSch to tell the server to use password auth
from the start rather than trying different auth methods?
I have the following code:
JSch ssh = new JSch();
Session session = ssh.getSession(<username>,<host>,<port>);
session.setConfig("StrictHostKeyChecking", "no");
session.setTimeout(15000);
session.setPassword(<pass>);
session.connect();
which is resulting in "Auth fail". I confirmed that password
authentication is enabled on the remote machine.
It appears from the SSH log (below) that it's trying to authenticate
against the server with methods: none, gssapi, and
keyboard-interactive before eventually failing with on "password" auth
possibly because we've failed too many times already.
