The Windows version of OpenSSH client doesn't include a ssh-copy-id command. I don't know why. If it does one day, then this can be ignored.

NOTE If you have Windows Subsystem for Linux (WSL) installed, you can use the linux version of ssh-copy-id instead. Go to the description at the end of this document.

Download the file ssh-copy-id.cmd to your Windows PC, or copy and paste its contents.
Run the script passing your linux ssh information (for example ssh-copy-id.cmd [email protected]). This should work with any Linux platform. Alternatively, if you have experience, you can use the powershell version. ssh-copy-id.ps1. Run the script as powershell .\ssh-copy-id.ps1 [email protected].
Run the command for each linux account you connect with. You will be prompted for your Linux host password. If you have more than 1 account on any machine, you must do this for each account.

The file name and location of the script is not important but the filename extension must be .cmd

WSL 2 Cisco AnyConnect Networking Workaround

Overview

WSL 2 uses a Hyper-V Virtual Network adapter. Network connectivity works without any issue when a VPN is not in use. However when a Cisco AnyConnect VPN session is established Firewall Rules and Routes are added which breaks connectivity within the WSL 2 VM. This issue is tracked WSL/issues/4277

Below outline steps to automatically configure the Interface metric on VPN connect and update DNS settings (/etc/resolv.conf) on connect/disconnect.

	1) ==== Autossh using systemd ====

	Example from

	https://gist.github.com/drmalex07/c0f9304deea566842490

	2) =============

	Install autossh

	#!/usr/bin/env bash

	# prereqs

	sudo apt update -y && sudo apt install -y \
	build-essential \
	libssl-dev \
	uuid-dev \
	libgpgme11-dev \
	squashfs-tools \

	# check execution policy
	If ((Get-ExecutionPolicy) -eq 'Restricted') {
	Set-ExecutionPolicy Unrestricted -Scope CurrentUser
	}

	# check powershell $PROFILE
	If (!(Test-Path $PROFILE)) {
	Write-Host "No PowerShell $PROFILE detected, creating one.." -ForegroundColor Magenta
	New-Item -ItemType File -Path $PROFILE -Force
	Write-Host "Created PowerShell Profile at: $PROFILE" -ForegroundColor Green

	#/bin/bash

	# Check if bridge-nf-call-iptables is enabled (1 if enabled)
	# cat /proc/sys/net/bridge/bridge-nf-call-iptables
	# Enable IP Forwarding
	# echo 'net.ipv4.ip_forward=1' >> /etc/sysctl.conf
	# sysctl --system

	CONTAINER_NAME=kube
	BRIDGED_NAME=br0


	Set-ExecutionPolicy RemoteSigned -scope CurrentUser
	$env:SCOOP='D:\prg\scoop'
	[environment]::setEnvironmentVariable('SCOOP',$env:SCOOP,'User')
	$env:SCOOP_GLOBAL='D:\prg\sapps'
	[environment]::setEnvironmentVariable('SCOOP_GLOBAL',$env:SCOOP_GLOBAL,'Machine')
	iwr -useb get.scoop.sh \| iex
	Set-ItemProperty 'HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem' -Name 'LongPathsEnabled' -Value 1
	scoop install 7zip innounp dark wixtoolset sudo curl git
	#sudo
