For reference, this is under Anaconda with python 3.6, on a Windows 7 machine (hence the additional file-path wrangling below) print(sshtunnel._version_)
The config is set up and working fine on the command-line using an SSH client. Remote_bind_addresses =)Įdit: trying out option 2, as outlined below.
Right now I don't know if I'm barking up the wrong tree - the docs suggest that I can create both tunnels in a single pass, but do I need two separate instances? from sshtunnel import SSHTunnelForwarder
#PYTHON 3 CREATE SSH TUNNEL TO SOCKET HOW TO#
I know the code below is incomplete and just plain wrong, as I can't figure out how to correctly combine the local/remote bindings. The ports underneath HOME and HOST are arbitrary, I just use them for illustration (in reality, the most convenient HOME port is also 8888) The server is bound to localhost, by default at port 8888. For clarity, HOME is the windows machine, HOST is the cluster head-node, and NODE is the particular node on which the server is running. I need to create two tunnels as outlined below. I am trying out sshtunnel, which is, unfortunately, my current stumbling block.
The ssh commands are handled through paramiko, and I'd like a similarly pythonic way of creating the tunnels, rather than just a system call. I have a script to launch Jupyter Notebook server running on a particular node of our cluster, and need to be able to access the running instance from a local windows machine (browser interface).
