Using the following model and naming conventions: It works with a combination of ssh config settings and the SSHTunnelForwarder context manager from the sshtunnel library. Tl dr: How do I forward a port through two ssh jumps in Python? I'm looking for something like this (modified from example 2 in the sshtunnel docs): import paramiko # successfully prints out MySQL welcome screen

Print("STDOUT:\n\n".format(stdout.read(), stderr.read())) Stdin, stdout, stderr = ssh.exec_command("mysql -u D_username -p D_password -h D_host_rds") Ssh.connect("C_host", username="C_username", sock=proxy) Proxy = paramiko.Prox圜ommand("ssh -A -W C_host:12345") Ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) I can access D by executing a command on C, but not by connecting with mysqldb or sqlalchemy (my ultimate goal). So far, I'm using paramiko with a proxy command to get from A to C.

Connecting to remote Postgresql database over ssh tunnel using python.

a double ssh tunnel to an SQL host (ex.

a single ssh tunnel and a remote SQL host (ex.

All of the information I can find involves: I would like to access D through Python, using paramiko and/or sshtunnel. I need a double ssh tunnel to then access a remote SQL host. C is accessible via ssh through a jump host "B". For security purposes, it is only accessible through a remote server ("C"). Transport.request_port_forward(args, args args)Ĭhannel.I have a remote MySQL database hosted on Amazon RDS ("D"). I've only done this with reverse tunnels in a threaded environment and it was pretty difficult to get working right since you have to also open local sockets and handle the data from the tunnel and the socket switching rx and tx buffers back and fourth while the tunnel is up.Įventually you'll end up with something like if you allow paramiko to use its built in handler you dont have to run multiple threads if you write your own handler you need to manage threading yourself, if you do make sure to keep a lock to manage the tunnel state before sending commands that need the tunnel up to run. are you calling the client method and then manually getting transport and opening a command channel? if not you're going to need to split out your channels and then open a forward channel. It really depends on if you're using the built in handler or not.
