Run SOCKS proxy on Android

Sun, 27 Oct 2024 00:00:00 GMT

(This is more of a reference than a blog post)

The goal is to browse the internet from a PC using the phone's mobile data through a hotspot, as if the traffic was coming from the phone.

Install Termux
1. Note: I had to use the one from F-Droid since the Google Play version caused an "access denied" error somewhere during the process below.
Create hotspot

In Termux:

# Download Glider
# https://github.com/nadoo/glider

wget 'https://github.com/nadoo/glider/releases/download/v0.16.3/glider_0.16.3_linux_arm64.tar.gz'
tar -xvzf glider_0.16.3_linux_arm64.tar.gz
cd glider_0.16.3_linux_arm64

# Get IP of the phone
ifconfig

# Start Socks proxy
./glider -verbose -listen :8443

Connect PC to hotspot
Configure web browser to use the phone IP and port 8443 as a SOCKS5 proxy

Raspberry Pi Zero W WiFi Bridge

Use the Raspberry Pi Zero W to bridge two wireless networks.

Use nmtui to connect the USB WiFi adapter to the WiFi network for the internet connection
Disable auto connect for the preconfigured connection

https://gist.github.com/narate/d3f001c97e1c981a59f94cd76f041140

CONNECTION_NAME=hotspot
SSID=my-ssid
INTERFACE=wlan0 # Interface for hosting the hotspot
PASSWORD=HJbiuAUYvo873bhyaF

# autoconnect is no because it will be started by the `start-hotspot.sh` script
nmcli con add type wifi ifname $INTERFACE con-name $CONNECTION_NAME autoconnect no ssid $SSID
nmcli con modify $CONNECTION_NAME 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared
nmcli con modify $CONNECTION_NAME wifi-sec.key-mgmt wpa-psk
nmcli con modify $CONNECTION_NAME wifi-sec.psk "$PASSWORD"
nmcli con up $CONNECTION_NAME

I had a problem where the hotspot had to be started after the internet interface is up. Solution:

https://askubuntu.com/a/1015291

/etc/NetworkManager/dispatcher.d/start-hotspot.sh

!/bin/bash

interf=$1
state=$2

# TODO: change `my-ethernet-device` and `my-hotspot`
if [ $interf = "my-ethernet-device" -a $state = "up" ]; then
    nmcli connection up 'my-hotspot'
fi

if [ $interf = "my-ethernet-device" -a $state = "down" ]; then
   nmcli connection down 'my-hotspot'
fi

Using Dev Containers with Podman and Selinux

Trying to use Podman with Development Containers without first modifying the devcontainer.json results in access denied errors within the container.

Add the following to devcontainer.json.

"runArgs": [
		"--userns=keep-id",
		"--security-opt=label=disable"
	  ],
"containerEnv": {
		"HOME": "/home/vscode" // TODO: change to the directory of the default user in the container
	},
