where do you set the user pass?

How do you set the login user and pass?

[zemin-piao]

By default it bypasses the check for login user+pass.

This can be changed by changing the code here:

class StubServer(ServerInterface):
    def check_auth_password(self, username, password):
        # all are allowed
        return AUTH_SUCCESSFUL

Doesn't seem to work. I'm using this to host the server:

conn, addr = server_socket.accept()

transport = paramiko.Transport(conn)
transport.add_server_key(_STATIC_KEY)

transport.set_subsystem_handler(
    'sftp',
    paramiko.SFTPServer,
    StubSFTPServer)

server = sftpserver.stub_sftp.StubServer()
transport.start_server(server=server)

channel = transport.accept()

# Block until connection terminates
while transport.is_active():
    time.sleep(1)

..where this is sftpserver.stub_sftp.StubServer:

class StubServer (ServerInterface):
    def check_auth_password(self, username, password):
        # all are allowed
        return AUTH_SUCCESSFUL
        
    def check_auth_publickey(self, username, key):
        # all are allowed
        return AUTH_SUCCESSFUL
        
    def check_channel_request(self, kind, chanid):
        return OPEN_SUCCEEDED

    def get_allowed_auths(self, username):
        """List availble auth mechanisms."""
        return "password,publickey"

Yet, when I don't set a key into the client, I always get an authentication failure:

  File "/home/dustin/.pyenv/versions/workflow_application/lib/python3.8/site-packages/paramiko/transport.py", line 1414, in connect

    return self.auth_handler.wait_for_response(my_event)
