2) Upload Minimal Kali Linux ISO
- Login to the user account, Navigate to 'Servers-->ISO' and we have to provide below Minimal Kali Linux ISO link by clicking 'Add ISO' option and after that click on 'Upload'.
- Wait for some time and the status of uploaded ISO will be changed to Available.
3) Install Kali Linux Complete System
Click the + sign on the right side of the application to deploy servers.
Choose the Server Location as 'Miami' which will unlock the cheapest VPS pricing $2.50/month
Select the Uploaded Minimal Kali linux ISO 'minimal.iso' as server type
You should be able to see and select VPS plan of $2.50/month.
Fill the remaining fields and Click on 'Deploy Now' submit button to create the instance.
Status of your new instance should be running and click on 'View Console' as it's time to install Kali Linux on the box.
Start the Kali Linux Installation and continue with next steps based on your preference.
Choose only 'SSH server' & 'standard system utilities' during Software Selection.
You will be able to see the Installation Complete screen if everything goes right.
Make sure to remove the uploaded custom ISO from Vultr server settings.Otherwise, your instance will get stuck on Installer Boot Menu during startup.
Finally, we are able to access minimal Kali Linux via Console.Also, It should be capable of making Inbound/Outbound connections to the internet.
We have to install Kali Linux Complete System by using kali-linux-full metapackages.
[email protected]:~# apt install kali-linux-full
Kali Linux Complete System is live now.
4) Set up SSH server
We don't want to access our box every time via Web Console.So, We can enable SSH Service from Kali Linux and can add that in the startup.By default, SSH service will not be enabled in Kali Linux.
Login to the box via Web console and Edit the 'sshd_config' file.
[email protected]:~# nano /etc/ssh/sshd_config
Inside the 'sshd_config', Uncomment and Edit the following lines.
5) Fixing Network Interface Card (NIC) issue
I have observed that kali linux is not configuring the network interface correctly after reboot.It changed interface from ens3 to eth0 and you cannot make Inbound/Outbound connections to internet.
To fix the Issue:
Check your network interface by using
If you cannot find ens3 or eth0 interfaces , Type
dhclientto automatically assign Static IP Address using DHCP protocol. Reconfirm it using
ifconfigcommand and this fix is temporary.
In order to fix this issue permanently, We can use DHCP to automatically configure the interface by editing network interface configuration file.
[email protected]:~# nano /etc/network/interfaces
iface eth0 inet dhcp
I am getting Upload & Download speed in between 100-200 MB/sec. Have calculated it using 'speedtest-cli'.
7) Bonus Tips & Advice
You can use Tmux or Screen to keep the sessions on the server when you access the box via SSH.
After installing Kali Linux in Vultr, Don't forget to secure your box. As it is exposed on the internet, Keep updating security patches, Audit your server and do the necessary hardening.
With Great Power Comes Great Responsibility, Hacking into someone else’s systems are illegal. Make sure that you have explicit permission before breaking into other systems.Also, Read Vultr use policy.
