How fun is Windows?

Tags: , , ,
Received new laptop that runs Windows 11 over the weekend.


Had spent some times on customize a few things:
  1. Install Google_Pinyin 
  2. Setup the input method switching to (left) ctrl-shift notkey.
  3. Install WSL/WSL2
  4. Install Windows Terminal
  5. Install Multipass (VM orchestrator)
  6. Setup ssh-keygen
  7. Create sample multipass VM with cloud-init
  8. Install python3 (in Windows 11)

Between WSL and Multipass, I need to setup the routing in order for them to communicate.

PS> Set-NetIPInterface -ifAlias "vEthernet (WSL)" -Forwarding Enabled
PS> Set-NetIPInterface -ifAlias "vEthernet (Default Switch)" -Forwarding Enabled

And to show the final routing table:
PS> Get-NetIPInterface | select ifIndex,InterfaceAlias,AddressFamily,ConnectionState,Forwarding | Sort-Object -Property IfIndex | Format-Table

One the routing is configured, then I proceed with ssh-keygen and setup the public key authentication between WSL and multipass.

~$ cd .ssh
~/.ssh$ ssh-keygen -t ed25519 -C "xx@wsl2"
~/.ssh$ ssh-keygen -l -f id_ed25519.pub
~/.ssh$ ssh-copy-id -i id_ed25519.pub xx@remote_server


Next, I need to setup multipass VM with cloud-init.

Create a cloud-init.yaml file for multipass:
-------------------------------
users:
  - default
  - name: xx
    groups: sudo
    shell: /bin/bash
    sudo: ['ALL=(ALL) NOPASSWD:ALL']
    ssh_authorized_keys:
      - ssh-rsa <rsa keys in one line>
package_update: true
package_upgrade: true
packages:
  - nodejs
  - python3
-------------------------------


PS> multipass multipass launch -c 2 -m 2G -d 20G -n ubuntu-vm --cloud-init cloud_init.yaml


Learnt some tricks in Windows command line. I install Python (with cmdline) and locate where is the python.exe.

PS> winget install python --source msstore
PS> where python
