            Asked 2021-Dec-01 at 13:04

            My application needs remote control over SSH. I wish to use this example: https://asyncssh.readthedocs.io/en/latest/#simple-server-with-input

            The original app is rather big, using GPIO and 600lines of code, 10 libraries. so I've made a simple example here:

            You have basically three options:

            Rewrite your main loop to be asyncio compatible

            A main while True loop with lots of sleeps is exactly the kind of code you want to write asynchronously. Convert this:

            Asyncio big list of Task with sequential combine run_in_executor and standard Coroutine in each
            Asked 2021-Jan-15 at 20:29

            I need to handle list of 2500 ip-addresses from csv file. So I need to create_task from coroutine 2500 times. Inside every coroutine firstly I need to fast-check access of IP:PORT via python module "socket" and it is a synchronous function want to be in loop.run_in_executor(). Secondly if IP:PORT is opened I need to connect to this socket via asyncssh.connect() for doing some bash commands and this is standart asyncio coroutine. Then I need to collect results of this bash commands to another csv file.

            Additionaly there is an issue in Linux: system can not open more than 1024 connections at same time. I think it may be solved by making list of lists[1000] with asyncio.sleep(1) between or something like that.

            I expected my tasks will be executed by 1000 in 1 second but it only 20 in 1 sec. Why?

            Python: concurrently pending on async coroutine and synchronous function
            Asked 2020-Jun-15 at 15:01

            I'd like to establish an SSH SOCKs tunnel (using asyncssh) during the execution of a synchronous function. When the function is done I want to tear down the tunnel and exit.

            Apparently some async function has to be awaited to keep the tunnel working so the important thing is that conn.wait_closed() and the synchronous function are executed concurrently. So I am quite sure that I actually need a second thread. I first tried some saner things using a ThreadPoolExecutor with run_in_executor but then ended up with the abysmal multihreaded variant below.

            Vulnerabilities

            CVE-2018-7749 CRITICAL
            The SSH server implementation of AsyncSSH before 1.12.1 does not properly check whether authentication is completed before processing other requests. A customized SSH client can simply skip the authentication step.

            Install asyncssh

            You can install using 'pip install asyncssh' or download it from GitHub, PyPI.
            You can use asyncssh like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
