+
+# Introduction
+
+In this tutorial, I will guide you through the process of accessing your root-server from Termux (android terminal application installed via F-Droid) on an android phone.
+
+The reading time of this tutorial is about 30 minutes; implementation will take approximately 90 minutes. The tutorial is for intermediate to advanced users only.
+
+# Background
+
+Termux is a powerful terminal emulator for Android that gives you access to a Linux environment right on your smartphone. With it, you can:
+
+- Run Linux commands
+- Control remote servers using SSH
+- Install tools like Nmap, Metasploit, or Hydra
+- Learn ethical hacking and cybersecurity
+- Code in Python, Bash, C, and more
+- Root access not required
+
+# Prerequisites
+
+- A Root Server from netcup with latest Ubuntu 20.04/22.04 (LTS); Debian 11/12 or later installed
+- Root access to your server
+- Android phone with Android version between 5 - 12; CPU: AArch64, ARM, i686, x86_64; at least 300 MB of disk space.
+- Basic and above knowledge of using terminal
+- Termux already [installed via F-Droid](https://wiki.termux.dev/wiki/Installing_from_F-Droid).
+- Secure your root server with [this guide](https://community.netcup.com/en/tutorials/first-steps-to-protect-your-linux-server-against-common-attacks).
+
+N.B.: The Play Store version of Termux is [no longer maintained](https://wiki.termux.dev/wiki/Termux_Google_Play)' and doesn’t support the latest packages or repositories.	
+
+Optional: You may also like to install [termux addons](https://wiki.termux.dev/wiki/Termux:API) & [termux styling](https://f-droid.org/en/packages/com.termux.styling)'
+
+# Step 1: Update your termux packages
+
+Before we begin, it's essential to ensure that your termux pacakges & system are up-to-date. 
+
+Open Termux and update packages Run this command:
+
+```
+pkg update -y && pkg upgrade -y
+```
+
+Note: If you are looking for a easy guide to install & setup basics of Termux, check [this guide](https://docs.nexoscreator.tech/termux-os/termux-app/installation/).
+
+![Termux Main Window](images/01_Main_Screen.jpg "Main Window")
+
+# Step 2: Install SSH server
+
+Next install openssh, which is required to start the SSH server.
+
+```
+pkg install openssh -y
+```
+
+After installing openssh, our SSH host configurations and keys are stored under /data/data/com.termux/files/usr/etc/ssh/
+
+Optional: If you like, you can also add the following additional termux repositories:
+
+```
+echo "deb https://grimler.se/termux-packages-24 stable main" > $PREFIX/etc/apt/sources.list
+echo "deb https://grimler.se/termux-packages-24 stable main" > $PREFIX/etc/apt/sources.list.d/game.list
+echo "deb https://grimler.se/termux-packages-24 stable main" > $PREFIX/etc/apt/sources.list.d/science.list
+```
+
+
+# Step 2: Create SSH Private/Public Key Pair on Android - Termux
+
+In our android device, we need to generate SSH key pair for connecting to SSH server the remote machine (example debian). So, run the following command (this will also name the file as android for easy referencing):
+
+```
+ssh-keygen -t ed25519 -f id_ed25519_android
+```
+
+
+This will create the public & private key files in the `~/.ssh` folder (**/data/data/com.termux/files/homes/.ssh**)
+
+# Step 3: Send SSH Public Key to Remote Machine
+
+Run `cat ~/.ssh/id_ed25519_android.pub` from termux which will return the public key for your android device.
+
+It will be something like this:
+
+```
+ssh-ed25519 ABCDE1AaaA1aAAA1AAA1AAAAAAAAAaaaA1AaaAaaaAaaa1aAAAAaaAAAAaAaaaAAaaAA user@host
+```
+
+
+Now copy and paste this key to your remote machine either via the chat box option in the file transfer assistant app [PlainApp](https://f-droid.org/en/packages/com.ismartcoding.plain/) or copying the `id_ed25519_android.pub` file across to your remote machine (using a USB connection) and then copy the content to `~/.ssh/authorized_keys` file (`$HOME/.ssh/authorized_keys`).
+
+# Step 4: Restart SSHD service on android
+
+Kill/end any running `sshd` service by typing in termux: `pkill -9 sshd`. This is to let go of any cache or broken service pipes.
+
+Now rerun `sshd` command to start the SSH server.
+
+# Step 5: Connect to your remote server
+
+Connect to your remote server using the private key as pairing for the public key, via:
+
+```
+ssh -i ~/.ssh/id_ed25519_android user@host -p 1234
+```
+
+![SSH Connected](images/02_SSH_Connected.jpg "Connected to remote")
+
+Optional: Run some command to check everything works as intended. Example:
+
+![Commands being run](images/03_Commands_Run.jpg "Running few commands")
+
+## Guidance and reverse idealogies
+
+[Termux Wiki](https://wiki.termux.com/wiki/Remote_Access) | [Termux Repos](https://grimler.se/termux/) | [Reverse Logic From](https://exploit-notes.hdks.org/exploit/mobile/android/connect-to-android-from-pc/)
+
+# Conclusion
+
+Now you have a secure connection to your server from your android phone, and with lesser reliability on a laptop/desktop.
