Ubuntu LTS Configuration Guide

Used by us internally, this guide walks you through the process of configuring SSH access, running the installation script, and performing the post-install setup for your Ubuntu LTS server.

Installation

1. After downloading the repository to your server, copy your SSH public keys into the "your_keys" directory.
2. Run the installation script.

sudo chmod +x install.sh && sudo ./install.sh

This will:

• Update all packages.
• Install necessary packages.
• Use the provided SSH credentials to configure and create a user named maintainer.
• Configure UFW.
• Configure automatic security updates.
• Configure NTP.

Post-Install Steps

1. Set a password for maintainer user:

sudo passwd maintainer

2. Unlock the maintainer account:

sudo passwd -u maintainer

Cleanup

If you need to remove an old user account (e.g., olduser):

# Kill any running processes
sudo pkill -u olduser

# Delete the account and its home directory
sudo userdel -r olduser

Accessing the Server

After installation and post-install steps:

1. Restart the server.
2. Connect via SSH:

ssh -p 18156 maintainer@server
