BASH ON WINDOWS 10 – WINDOWS SUBSYSTEM FOR LINUX DEMO

Pre-Reqs
    Basic knowledge of Linux
    Windows 10 Anniversary Update Installed
    Systems Administration / Network Administration Experience

SETUP BASH ON UBUNTU ON WINDOWS 10	
    Enable Developer Mode, restart, type “bash” to install, press “y”
    Run basic update commands
    Lsb_release -A
    Explain more about WSL / LXSS
        Files live in %localappdata%\lxsss
        To reset / completely remove:
	        Lxrun /uninstall /full
        To reinstall
	        Lxrun /install
    Basic Linx commands demo

        SSH

    Guide for configuring Password SSH
        1. Edit /etc/ssh/sshd_config and change the listening port. For this demo I used port 222.
        2. Change UsePrivilegeSeparation to ‘no’ (because the implementation of the Windows subsystem for Linux doesn’t provide chroot)
        3. Change PasswordAuthentication to ‘yes’
        4. Add a firewall rule on the Windows side for SSH to your new listening port
        5. sudo ssh-keygen -A
        6. Restart the ssh service: sudo service ssh restart (Ignore the message: “initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused”)
        7. Test ssh connection locally with verbose mode enabled (verbose mode optional): ssh localhost -p “your-port-here” -v
        8. Test from another system. (All should be working)
        
    Guide for configuring Password-less SSH

        1. Edit /etc/ssh/sshd_config and change the listening port. For this demo I used 222
        2. Change the UsePrivilegeSeparation to ‘no’ (because the implementation of the Windows subsystem for Linux doesn’t provide chroot)
        3. Add a firewall rule on the Windows side for ssh to your new listening port
        4. sudo ssh-keygen -A
        5. Restart the ssh service: sudo service ssh restart (Ignore the message: “initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused”)
        
        Do this from client machine (system tunneling to Bash on Ubuntu on Windows):
        1. cd ~/.ssh
        2. ssh-keygen -t rsa
        3. ssh-add [keynamehere]
        3. cat ~/.ssh/keynamehere.pub | ssh [username]@[ip-address-here] -p 222 'umask 0077; mkdir -p .ssh; cat >> .ssh/authorized_keys && echo "Key copied"'

        To connect to your system running Bash on Ubuntu on Windows (server) from your client, run the following:

        ssh username@server-ip-address -p “your-port-here” and you should be able to connect now without a Password

        ** Remember to update your /etc/ssh/sshd_config file, disable PasswordAuthentication, and restart the service by typing sudo service ssh restart
