SSH sessions hang if using WSL2 linux or any linux container

UPDATE : Nope, it's even PowerShell ... (discovered this after revision 4 of this gist)

TLDR; Suspect the virtual machine platform, requried for any containerized system (including Rancher/Docker desktop) is the source of the ssh hangs, as a PowerShell ssh has no hang issues.

This is a known issue for 4 years now

Tried using a Linux container and ssh behaves similarly

  • Used Rancher Desktop with the following command, running an ssh session hung the terminal in short order

Attempt to get around WSL2

So, tried disabling some Windows Features

  • disabled NO hyper-v service (it was already even prior the last ssh hang)
  • disabled virtual machine platform and that prevents WSL2 or any 'containerization' from running.

install choco

Why? Just wanted to confirm Docker needed the virtual macine platform service. It does.

Requires Admin Shell

Set-ExecutionPolicy Bypass -Scope
Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

choco install kind

  • installs docker desktop
  • does it re-enable virtual machine platform? No, but it also doesn't start up.

Summary: Fuck Windows Subsystem for Linux
