![]() An example, if you use the ufw firewall on the server then you need to run this command to allow the SSH connection from your Android phone or any other SSH client: sudo ufw allow ssh SSH on Linux from Android SSH Android client setup You then need to configure the firewall to allow the SSH traffic on it. If the service is not running, then run these commands to start the service and also to enable the auto start on system startup: sudo systemctl enable sshĪnother important part of this setup is that if you have a firewall installed on your server. Verify that the SSH service has started and is running: sudo systemctl status ssh.service Commands to install OpenSSH server on Debian/Ubuntu based distros: sudo apt update & sudo apt upgrade -y But, if you don’t have an SSH server installed, you can install OpenSSH server for an example. On some distros, SSH server comes installed by default. Another important piece for this setup is that your server has an SSH server installed. Like stated earlier, first you need to already have access to your Linux server and also be able to use the terminal as well. ![]() In order to set this all up, you already need to have an access to the server you wish to enable SSH access. Also, we’ll cover the steps of creating the SSH keys and installing those on our server as well. Meaning that with this setup, we’ll be able to access our Linux servers, from an SSH Android client app from within the LAN network and also remote servers – like cloud servers. Like it’s mentioned in the title, we’re going to SSH on Linux from Android phone or in another words – setup an SSH connection to our Linux server from an Android phone. You can also use the Termux widget to quickly start sshd with a widget.How to SSH on Linux from Android Overview bashrc file and I am using Tasker to launch Termux after boot. Right now I have the 'sshd' command in my. I hope in the future Termux will allow us to register sshd as a proper service which would automatically start on system boot. The reason usually are bad permission on either your home directory, your. If it is still prompts you for a password you can enter sshd's debug mode with the above command and see exactly why your key has been rejected. You should now be connected to your Android device via SSH. Under Connection>SSH>Auth you can browse for the *.pkk file.Enter the IP address of your Android device and use port 8022.If you're using PuTTY you will need to convert it to the PuTTY Private Key format first. Ssh $IP -p 8022 -i %PATH_TO_KEY-FILE%/%NAME_OF_KEY% PuTTY If you're using OpenSSH (on Linux or Cygwin) you can use it directly: # -i $PATH_TO_FILE/filename is only required if the id_rsa file is not ~/.ssh/id_rsa Simply copy it to your computer (by copying it to internal storage first cp ~/.ssh/id_rsa /sdcard) and use it in your ssh client. You can now use your private key (~/.ssh/id_rsa) to login to your Termux SSH Server. Ssh localhost -p 8022 -i %PATH_TO_KEY-FILE%/%NAME_OF_KEY% Then you can test it by connecting to your ssh service # -i $PATH_TO_FILE/filename is only required if the id_rsa file is not ~/.ssh/id_rsa You can then add it to the ~/.ssh/authorized_keys with cat ~/.ssh/id_rsa.pub > ~/.ssh/authorized_keys You may or may not enter a passphrase and if you don't specify otherwise, your key pair will have been saved under ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub. ![]() If you do not have a OpenSSH key pair yet, you can generate one with the following command: ssh-keygen This file will need to be created and permissions set to 600. You can't do password authentication in Termux, therefore you need to put your OpenSSH public key into the ~/.ssh/authorized_keys file. ssh localhost -p 8022 Adding your Public key Your ssh service is now running on port 8022. You need to install the OpenSSH package apt install opensshĪnd use following command to start the ssh server. Previously I used SSHDroid to achieve this, but with Termux is much nicer because you have access to a working package manager. With the brilliant Termux terminal emulator app you can run an SSH server on your Android.
