Accessing Android Phone via ssh

Sometimes, for whatever reason, you need to access your phone from your laptop. This can be done by installing openssh inside your phone.

First, you need an app called termux, to enable terminal emulator inside android. The app can be downloaded here, in google play store.

Once installed, fire up termux, and install openssh 

$ pkg install openssh

You need password to login via ssh, so set a password for your current user

$ passwd

You also need to know, what is the current username

$ whoami

Run sshd. By default sshd in termux runs on port 8022

$ sshd

Get the ip address of your android phone

$ ip addr show wlan0

Connect to your phone (replace 192.168.43.200 with the output of the ip addr command), using standard ssh client on linux/mac terminal, or putty on windows

$ ssh u0_a211@192.168.43.200 -p 8022 

In order to browse the whole internal storage of your phone, you need to enable storage permission for termux. That can be done by running:
$ termux-setup-storage

and clicking allow
