Using existing SSH session with Paramiko

Question

Imagine that you have a client and a server and that the client connects to the server using SSH (with or without Paramiko). Is it possible for Paramiko to utilize the already open SSH connection instead of creating a new one, so that another script can be ran on the server (and transfer a file back to the client for example) using the same existing connection? The goal is to avoid establishing multiple connections.

Answer 1

This is not really a programming/Python/Paramiko question. It's not possible with SSH at all. So it's not possible with Python/Paramiko either.

See

• Transfer files to/from session I'm logged in with PuTTY or
• Can you use SFTP to transfer files "backwards" to client during SSH on host?

Though if you connect with a (Python or whatever) script from the client machine, the remote script can talk to the local script to exchange the data (and the local script can save the data to a file).
