Basic Server Setup

Standard procedure for setting up a new Debian/Ubuntu server in this environment.

1. Initial Update

Always start by updating the package lists and upgrading existing packages.

sudo apt update
sudo apt upgrade -y

2. Install Common Tools

Install utilities frequently used for maintenance and monitoring.

sudo apt install -y curl wget git tmux btop iftop net-tools unzip

3. Secure SSH Access

Security best practice: Disable password authentication and root login.

1. Create .ssh directory (if not exists):

   mkdir -p ~/.ssh
   chmod 700 ~/.ssh

2. Add Authorized Key: Paste your public key into ~/.ssh/authorized_keys.

   nano ~/.ssh/authorized_keys
   chmod 600 ~/.ssh/authorized_keys

3. Configure SSH Daemon: Edit /etc/ssh/sshd_config:

   sudo nano /etc/ssh/sshd_config

   Ensure these settings are set:

   PermitRootLogin no
   PasswordAuthentication no
   PubkeyAuthentication yes

4. Restart SSH:

   sudo systemctl restart sshd

4. Set Hostname

sudo hostnamectl set-hostname <new-hostname>
