UPnP Tomfoolery

Turns out, UPnP is terrible when it comes to security. The entire protocol exists to have devices easily find and connect to one another without any authentication at all. This is all good fun to poke around with. Here are a few tools and notes I've found along the way.

UPnP devices can be found by listening to UDP packets on port 1900. To actively discover these services on your network, send an HTTP M-SEARCH request to the default UDP mulicast address: 239.255.255.250.

There are some great Linux tools that make interfacing with all of these stuff a synch:

sudo apt update

mvadu

#!/bin/bash
#~/bin/upnpPortMapper.sh
#sudo apt-get install miniupnpc
#crontab -l | grep upnp || echo $(crontab -l ; echo '*/5 * * * * ~/bin/upnpPortMapper.sh  >/dev/null 2>&1') | crontab -

export LC_ALL=C
router=$(ip r | grep default | cut -d " " -f 3)
gateway=$(upnpc -l | grep "desc: http://$router:[0-9]*/rootDesc.xml" | cut -d " " -f 3)
ip=$(upnpc -l | grep "Local LAN ip address" | cut -d: -f2)

Install stable-diffusion-webui on Termux (Android) + PRoot

This will guide you on installing AUTOMATIC1111/stable-diffusion-webui on Termux (Android) + PRoot Distro. Make sure that you have a high-end phone to actually make this usable. On my phone with 8GB RAM, launch the webui alone take at least ~ 2 GB RAM, thus making it impossible to load any model and process further.

1. Prerequisites

First you have to install Termux and install PRoot. Then install and login to Ubuntu in PRoot

2. Installing AUTOMATIC1111/stable-diffusion-webui
