Use proxychains in wsl

wsl-proxychains.sh

#!/bin/bash
# wsl's host ip address may change every time it reboots,
# this is a problem if you map your host address as proxy.
# Use the script to generate a new config of proxychains
# each time proxychains runs.
# put an entry 
#     http wsl-host 3128
# in your /etc/proxychains.conf
# Copy the script as ./local/bin/wsl-proxychains.sh
# run your program with proxychains like
#     wsl-proxychains.sh <YOUR PROGRAM>

gateway=`ip route|grep default|grep eth0|cut -d' ' -f 3`
sed "s/wsl-host/${gateway}/g" /etc/proxychains4.conf > /tmp/proxychains.conf
proxychains -f /tmp/proxychains.conf $@
