Follow these steps:

1. Open Termux on your Android phone
2. Install OpenSSH:
   pkg upgrade
pkg install openssh
3. Set up a password:
   passwd
4. Find your username by running this in Termux:
   whoami¹
   Save this value for later. Might look like
   u0_a254
5. Find the host by running this in Termux:
   ipconfig ¹
   Look for something like
   inet addr:192.168.0.100
   Save this value for later.
6. Start the ssh server on Termux:
   sshd
   Verify that it’s running with:
   logcat -s 'ssh:*'
   You should see something like
   “Server listening on port 8022”
7. On your computer, SSH into your machine on port 8022 (default port):
   ssh <username>@<jjhost> -p8022
8. Type in your password and viola!
   You’re accessing Termux from your computer.
