Connect Android to PC with Termux

Termux

Here is the introduction of termux from its official website:

Termux is an Android terminal emulator and Linux environment app that works directly with no rooting or setup required. A minimal base system is installed automatically - additional packages are available using the APT package manager.

It is thrilling that we could use our phone as a free server without making any damage. But it is painful to type with such small screen and no control or arrow keys. (link for some special keys) Therefore, it would be better that we could use our PC to the phone. Since we are using linux, it is natural to use ssh.

Some steps

First, at the phone side, we need to install openssh and enable ssh connection.

apt install openssh
sshd

Then, we need to send the private key from the PC to the phone. I did not connect them with sshd successfully, therefore use wechat to send the key and past it to the .ssh/authorized_keys in the phone.

And after figure out the ip and username of the phone:

ifconfig
whoami

We could connect with ssh from the PC using:

ssh username@ip -p 8022
