# Guide to configure WSL2 Squid, SSH, and Fish #
################################################

### Run all of this inside an Ubuntu WSL instance (must enable WSL2 and install Ubuntu WSL first)

# Allow us to start ssh and squid without a password
# echo "%sudo ALL=(ALL) NOPASSWD: /etc/init.d/ssh" | sudo tee -a /etc/sudoers.d/password-inits.conf
# echo "%sudo ALL=(ALL) NOPASSWD: /etc/init.d/squid" | sudo tee -a /etc/sudoers.d/password-inits.conf
echo "$(whoami) ALL = (ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/passwordless-sudo

# Install packages
sudo apt update
sudo apt install openssh-server net-tools squid npm

# Generate keys for sshd
sudo ssh-keygen -A

# Change default Squid configuration to allow local network access \
sed -i 's/^#http_access allow localnet$/http_access allow localnet/' /etc/squid/conf.d/debian.conf;

# Install node
install n and node 12.20.1
sudo npm i -g n
sudo n 12.20.1
n

# Enable Chrome Headless
export CHROME_BIN=/mnt/c/Program\ Files/Google/Chrome/Application/chrome.exe

# Install fish and themes
sudo apt-add-repository ppa:fish-shell/release-3
sudo apt update
sudo apt install fish
chsh -s $(which fish)

### Run all of this inside Admin Powershell

# From an admin powershell, schedule this scirpt to run. For example
