Serv = socket.socket(socket.AF_INET, socket. Ip = "" # replace your ip addressĬlient = socket.socket(socket.AF_INET, socket.SOCK_STREAM) I remember the same problem, probably you forgot to encode() and decode() your messages. The client connects to the server but no data is sent with SSH tunneling, and I'm not sure exactly why. With PuTTY SSH tunneling enabled and the client going from localhost:1556 to the server through the tunnel, I receive 0 bytes: b'' even though i use flask sqlalchemy for this. When I connect the client to the server directly, I see the "hello world" message on the server side: b'hello world' In this video i talk about how you can connect to your mysql database on python anywhere using an ssh tunnel. Print(ndall(bytes('hello world', 'utf-8'))) With socket.socket(socket.AF_INET, socket.SOCK_STREAM) as sock: On the client side, I have a simple Python3 program that just sends hello world. For a recent project, I needed a convenient way to query private databases in Python to do some repeatable data management operations. This can be achieved by SSH Port Forwarding AKA SSH Tunneling. # Activate the server this will keep running until you The common strategy for connecting to one of these devices is to tunnel your traffic through a jump box AKA jump server AKA jump host. With socketserver.TCPServer((HOST, PORT), MyTCPHandler) as server: # Create the server, binding to localhost on port 9999 # self.request is the TCP socket connected to the client Override the handle() method to implement communication to the

It is instantiated once per connection to the server, and must The request handler class for our server. import socketserverĬlass MyTCPHandler(socketserver.BaseRequestHandler): On the remote server, I have a Python3 socket server running with code almost taken directly from. On my Windows computer, I have PuTTY running with a tunnel going from port 1556 to remoteipaddress:1556. Sending a password over SSH or SCP with subprocess.I am trying out SSH tunneling using PuTTY. How to interact with ssh using subprocess module Python popen() insert password when asked for Python - subprocess.Popen - ssh -t 'service -status-all' The only simple way to do SSH in Python today is to use subprocess + OpenSSH. connect to mongodb using python To create the database follow these steps Connect via MONGO shell SSH to the MongoDB host server or connect via your VPN. Even though this does not use paramiko, I believe it's a very clean solution to implement (similar to dario's answer but without managing the thread in python). Retourne par exemple une liste des fichiers sur la machine B: Références Liens import subprocess import sys host = command = "ls" ssh = subprocess.Popen(, shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE) result = () if result = : error = () print("ERROR: %s" % error ) else: print( result )

Il existe alors d'autres solutions: comme pexpect ou paramiko par exemple. Remarque: cependant subprocess n'est peut être pas la meilleure approche pour réaliser cela car il n'est pas simple par exemple de spécifier le mot de passe pour établir le tunnel ssh, ou encore de lancer plusieurs commandes à la suite. Le code ci dessous montre comment lancer une commande sur une machine distante B et récupérer le résultat ( source). Dans l'objectif d'établir un tunnel ssh sur un serveur distant (machine B) en passant par python (afin de pouvoir automatiser certaines taches par exemple), on peut utiliser subprocess.
