Obtain full access to the underlying VM inside Crostini containers

Overview

As you might know, all Crostini containers are running under the "unprivileged container" mode and are kind of restricted, which means:

• Unable to load any kernel modules
• Unable to mount any disk/loopback images natively (although you could use FUSE to achieve a similar result, that's complicated to use)
• Unable to setup device mappers

So what's the solution? This guide will cover things below:

import { options } from "preact";
import { Signal } from "@preact/signals";

// Add `bind:value` to JSX types
declare global {
  namespace preact.createElement.JSX {
    interface HTMLAttributes {
      "bind:value"?: Signal<string | string[] | number | undefined>;
    }
  }

I wasn't able to git fetch from Azure DevOps repos after upgrading openssh on my computer.

ssh -V
  OpenSSH_8.8p1, OpenSSL 1.1.1l  24 Aug 2021

Turns out that OpenSSL has now turned off ssh-rsa by default:

This release disables RSA signatures using the SHA-1 hash algorithm by default.

But Azure DevOps doesn't support anything else... Add the following to your config file to re-enable ssh-rsa for Azure DevOps:

Installing Homenet on your Router

This set of instructions configures a fresh LEDE installation to run Homenet. They will likely work on a current build of OpenWrt.

There's lots of good info about Homenet elsewhere. See the External References section (below).

The general strategy is to connect your computer to the router's LAN Ethernet, convert the wireless and WAN interfaces to run Homenet, and test the changes so far. After things are working, configure the LAN Ethernet to Homenet through connect one of the (now Homenet) wireless interfaces.

1. Install LEDE on your router. See the main Getting Started with LEDE page for details.
