SFTP-сервер на Python с Paramiko не разрешает SFTP-соединения ⇐ Python

[Anonymous]

Я переписал вопрос, потому что он не поместился ниже.
Я пытаюсь использовать библиотеку paramiko на Python для настройки SFTP-сервера.
Я начинаю определять ROOT_FOLDER для пути к желаемой папке.
Затем я расширяю paramiko.SFTPServerInteface:

Код: Выделить всё

class SFTPServer(paramiko.SFTPServerInterface):
def __init__(self, server: paramiko.ServerInterface, *args, **kwargs):
super().__init__(server)
self.root_folder = ROOT_FOLDER

def _resolve_path(self, path):
safe_path = os.path.normpath(os.path.join(self.root_folder, path.lstrip('\\')))
if not safe_path.startswith(self.root_folder):
raise IOError("Access denied.")  # Blocca accesso esterno a ROOT_FOLDER
return safe_path

def list_folder(self, path):
logging.debug("Listing folder files.")
full_path = self._resolve_path(path)
files = os.listdir(full_path)
return [paramiko.SFTPAttributes.from_stat(os.stat(os.path.join(full_path, f))) for f in files]

def stat(self, path):
full_path = self._resolve_path(path)
return paramiko.SFTPAttributes.from_stat(os.stat(full_path))

def open(self, path, flags, attr):
full_path = self._resolve_path(path)
mode = 'rb' if flags & os.O_RDONLY else 'wb'
return open(full_path, mode)

def remove(self, path):
full_path = self._resolve_path(path)
os.remove(full_path)

А затем paramiko.ServerInterface:

Код: Выделить всё

class SSHServer(paramiko.ServerInterface):
def __init__(self):
super().__init__()
self.event = threading.Event()

def check_auth_password(self, username, password):
if authenticate_user(username, password=password):
logging.debug(f"User {username} authenticated by password.")
return paramiko.AUTH_SUCCESSFUL
else:
logging.debug(f"Failed password authentication for user {username}.")
return paramiko.AUTH_FAILED

def check_auth_publickey(self, username, key):
public_key = key.get_base64()
if authenticate_user(username, public_key=public_key):
logging.debug(f"User {username} authenticated by public key.")
return paramiko.AUTH_SUCCESSFUL
else:
logging.debug(f"Failed public key authentication for user {username}.")
return paramiko.AUTH_FAILED

def check_channel_request(self, kind, chanid):
logging.debug(f"Channel request type: {kind}")
if kind == 'session':
return paramiko.OPEN_SUCCEEDED
else:
logging.debug(f"Channel type not supported: {kind}")
return paramiko.OPEN_FAILED_ADMINISTRATIVELY_PROHIBITED

def check_channel_subsystem_request(self, channel, name):
logging.debug(f"Channel request type (subsystem): {name}")
if name == 'sftp':
paramiko.SFTPServer(channel, 'sftp', self, SFTPServer)
return paramiko.OPEN_SUCCEEDED
return paramiko.OPEN_FAILED_ADMINISTRATIVELY_PROHIBITED

def check_channel_pty_request(self, channel, term, width, height, pixelwidth, pixelheight, modes):
return True

def check_channel_shell_request(self, channel):
self.event.set()
return True

def check_channel_exec_request(self, channel, command):
channel.send(b"Esecuzione del comando: " + command)
channel.send_exit_status(0)
return True

Я не знаю, правильно ли обрабатываются запросы оболочки, pty и exec.
В этой функции я обрабатываю клиентское соединение, но это не так. Не знаю, пришлось ли мне писать "transport.set_subsystem_handler" или строки с комментариями:

Код: Выделить всё

def handle_client(client_socket: socket.socket, host_key: paramiko.RSAKey):
try:

transport = paramiko.Transport(client_socket)
transport.add_server_key(host_key)

ssh_server = SSHServer()

try:
transport.start_server(server=ssh_server)
except paramiko.SSHException as e:
logging.error(f"SSH negotiation failed: {e}")
return

channel = transport.accept(40)
if channel is None:
logging.error("No channel found")
return

logging.info("Client authenticated.")
logging.debug("Starting SFTP session.")

#sftp_server = paramiko.SFTPServer(transport, sftp_si=SFTPServer(ssh_server, ROOT_FOLDER))
#sftp_server.start()

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

while not channel.closed:
time.sleep(1)

except paramiko.SSHException as e:
logging.error(f"SSH exception: {e}")
except Exception as e:
logging.error(f"Error handling client: {e}")
finally:
logging.debug("Closing channel.")
if channel != None:
channel.close()

Затем, чтобы запустить сервер, я использую эту функцию:

Код: Выделить всё

def start_sftp_server():
logging.info("Starting SFTP server...")

host_key = paramiko.RSAKey.generate(2048)

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(('localhost', 2222))
server_socket.listen(100)

client_socket, addr = server_socket.accept()

transport = paramiko.Transport(client_socket)
transport.add_server_key(host_key)

server = SSHServer()

transport.start_server(server=server)

channel = transport.accept()
logging.info("SFTP Server started.")
#transport.set_subsystem_handler('sftp', paramiko.SFTPServer(channel, 'sftp', server, SFTPServer))
while transport.is_active():
pass

Когда я пытаюсь подключиться к серверу с помощью такого программного обеспечения, как WinSCP или FileZilla, сеанс запускается, но он остается зависшим, я не вижу файлов, и время ожидания клиента истекает.
Вот логи парамико:
