Installing the OS

• Step 1: Setting up SSH keys
• Step 2 : Changing date/time
• Step 3: Create a New Sudo-enabled User in Ubuntu 22.04

I've chosen Ubuntu 22.04 as the choice for VPS OS.

Step 1: Setting up SSH keys

You'll require SSH keys in order to prevent logging in to computer with a password everytime.

In your local computer

$ ssh-keygen -t ed25519 -C "your_email@example.com"
# Follow the onscreen directions in order to generate the public and the private pair
$ cat YOUR_KEY.pub
# The public key will appear
# Copy the public key.

# Add the ssh key to the agent
$ ssh-add ~/.ssh/id_ed25519

In cloudcone web dashboard

Now go to the profile section in the dashboard of cloudcone and select SSH keys.

Paste the content that you've copied earlier.

Now it is time to login to the server.

Login to the server:

Open the terminal and type the following:

ssh root@YOUR_IPV4_IP

It will ask for your password which will be provided to you in the registered mail. Enter the password. Now it is time to install the SSH keys.

# STEP 2: INSTALL THE SSH KEY
$ curl -o cc-ikey -L web.cloudc.one/sh/key && sh cc-ikey some-random-key #it will be different for you.

Also, if you want to get information about the RAM usage in the system, then execute the following in the terminal.

$ wget -O install stats.cloudcone.sh && bash install some-random-string
# It will be different on every instances. The random string will be provided to you by cloudcone.

After the installation, you'll see the ram usage in cloudcone dashboard.

Step 2 : Changing date/time

To set the timezone, run the following command:

$ sudo timedatectl set-timezone Asia/Kolkata

Note:

If you want to get a list of time-zones available, you can use

$ timedatectl list-timezones

You can also use grep in order to narrow it down such as $ timedatectl list-timezones | grep Asia/Kolkata

Step 3: Create a New Sudo-enabled User in Ubuntu 22.04

$ adduser itachi

Output:

Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully

Changing the user information for sammy
Enter the new value, or press ENTER for the default
    Full Name []:
    Room Number []:
    Work Phone []:
    Home Phone []:
    Other []:
Is the information correct? [Y/n]

adding the user to the sudo group

$ usermod -aG sudo itachi

Testing sudo Access

sudo - itachi
