WSL add Windows host address to /etc/hosts

readme.md

This small gist will add automaticaly wsl.host to hosts file and you will be able to communicate with your windows system, using wsl.host as address.

After creating your wsl do next:

1. Place startup.sh at /startup.sh and run chmod +x /startup.sh
2. Run visudo
3. Add %sudo ALL=NOPASSWD: /startup.sh to end of file
4. Add sudo /startup.sh at end of file /etc/profile

That's all. After first login in wsl after system start wsl.host will point to your windows host

startup.sh

#!/usr/bin/env bash

hostsFile="/etc/hosts"
hostname="wsl.host"
ip=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2}')

die() { yell "$*"; exit 111; }
try() { "$@" || die "cannot $*"; }

remove() {
    if [ -n "$(grep -P "[[:space:]]$hostname" /etc/hosts)" ]; then
        try sudo sed -ie "/[[:space:]]$hostname/d" "$hostsFile";
    fi
}

add() {
    if ! [ -n "$(grep -P "[[:space:]]$hostname" /etc/hosts)" ]; then
        try printf "%s\t%s\n" "$ip" "$hostname" | sudo tee -a "$hostsFile" > /dev/null;
    fi
}

It is not working on my WSL, until manual launch sh-script.
