Unlimited Tethering (TERMUX-LINUX-WINDOWS)
Updated

Bypass tethering caps or throttling on cell phone unlimited data plans. Potentially cancel your internet and route your whole home though your unlimited data plan.

—Unlimited data plan
—Ability to hotspot your phone
—Computer or Router

1) Download Termux app, install openssh on it, make sure you have python2 as well and simlink the python2 command to python.

—pkg install python2

—py2_path=$(which python2)

—py_path=${py2_path%/*}/python

—ln -s "$py2_path" "$py_path"

2) Configure authentication as explained here for SSH. If you don't already have a keypair it explains how to set up an ssh keypair and use it to authenticate to your phone from a PC. I personally used my existing SSH public key and made a folder / file ~/.ssh/authorized_keys on Termux and dropped it in there with something like curl "https://github.com/rifi2k.keys" > ~/.ssh/authorized_keys if you already have your public keys on github .

3) Hotspot your phone.

Run ifconfig inside Termux to get your current tethering local IP. It will be the only 192.x.x.x spit out and generally for andriod will be ending in 192.x.43.x. Save this.

4) Run sshd -dD inside Termux which starts an openssh server in debug mode to audit traffic. Your looking to see something like this as output from the above command.

debug1: Bind to port 8022 on ::.
Server listening on :: port 8022.
debug1: Bind to port 8022 on 0.0.0.0.
Server listening on 0.0.0.0 port 8022.

5) Now pop onto a PC and connect it to your hotspot.

Now SSH tunnel all the traffic from the device back through the openssh server your running on the Termux app. Now that you are on the same local network you can SSH tunnel into our saved IP address and port from earlier 192.x.43.x:8022 or similar.

6) You can use ssh which would look something like this.

If you want to use OpenSSH on Windows my recommendation would be Chocolatey package manager. https://gitlab.com/DarwinJS/ChocoPackages/tree/master/openssh

TERMUX_USER="u0_a249"
TERMUX_IP="192.x.43.x"
TERMUX_PORT="8022"
LOCAL_SOCKS_PORT="8123"
ssh -D $LOCAL_SOCKS_PORT -fqgN $TERMUX_USER@$TERMUX_IP -p $TERMUX_PORT
TERMUX_USER would be your username on the Termux app. TERMUX_IP would be the IP you got from ifconfig in Termux. TERMUX_PORT would be the port sshd is using in Termux. LOCAL_SOCKS_PORT would be the port you want to use for your local proxy.

7) So then once you run the above ssh command you need to configure a system wide or application specific Socks Proxy which would be proxying all traffic to 127.0.0.1 for the Socks Host and whatever LOCAL_SOCKS_PORT is from above for the Socks Port.

I use sshuttle which already handles most of the gotchas with tcp over tcp etc. and which also has a solution for Windows and linux. Also sshuttle generally handles setting up the Socks Proxy for you. A command for sshuttle might look like this.
