Introduction

In this article, we’ll guide you through the process of Setting Up SSH on Kali Linux system for remote access. SSH (Secure Shell) is a crucial tool for accessing and managing your system from another computer. Let’s dive into the practical steps.

Setting Up SSH on Kali Linux

By default, Kali Linux comes with OpenSSH installed. To verify or install it, open the terminal and run:

   sudo apt update
   sudo apt install openssh-server

Reconfigure OpenSSH (Optional)

In case of misconfiguration, you can reconfigure OpenSSH using:

   sudo dpkg-reconfigure openssh-server

Edit SSH Configuration File

Navigate to the SSH configuration directory and edit the sshd_config file if it exists :

   sudo nano /etc/ssh/sshd_config

Inside the file, find the ‘PermitRootLogin’ option and change it to ‘yes’ if you want to enable root login.

Save and Exit SSH Configuration File

Use Ctrl + O to save changes and Ctrl + X to exit the nano editor u may use wq if you are on vim.

Restart SSH Service

Restart the SSH service to apply the changes and use the server Restarting is an important procedure to implement the changes:

   sudo service ssh restart

Check Local IP

Identify your Kali Linux machine’s local IP address or to be more concise if you are using Kali on VM Check vm8 adapters:

   ifconfig

Connect Remotely with PuTTY

On your Windows machine, use PuTTY to connect remotely to Kali, PuTTY is a Gui-based SSH Connection establishment. Open PuTTY, enter Kali’s IP address, set the port to 22, select SSH as the protocol, and click ‘Open’.

Enter Credentials

When prompted, enter your username (e.g., ‘root’) and the corresponding password this is generally the one you enter while generating the ssh_keygen. Now, you have successfully logged in remotely to your Kali Linux system.

Conclusion

Setting Up SSH on Kali Linux is a fundamental skill for remote access. By following these practical steps, even beginners can establish a secure and efficient connection to their Kali system.
