  To start a new tmux session:

  tmux

  In tmux, most commands are executed using Ctrl + b, followed by another key:

  Action	Shortcut
  Detach session (leave it running)	Ctrl + b, then d
  List active sessions	tmux ls
  Reattach a session	tmux attach -t session_name
  Exit session	exit or Ctrl + d

  
• unzip: A tool for extracting and viewing files in .zip archives

  Example usage:

• libguestfs-tools: A set of tools for accessing and modifying virtual machine disk images.

  Example usage (list files in a VM disk image):

  guestfish -a disk.img -m /dev/sda1 ls /

This option automatically installs these utilities by running this command:

# Update package lists
sudo apt-get update

# Install common system utilities
sudo apt-get install -y axel dialog dos2unix grc htop btop iftop iotop iperf3 ipset iptraf-ng mlocate msr-tools net-tools omping sshpass tmux unzip zip libguestfs-tools

        

2

Skip Downloading Additional Languages

This optimization configures APT to skip downloading additional language packages, which can save disk space and speed up package operations.

Why it's beneficial:By skipping unnecessary language packages, you can reduce disk usage and improve the speed of package management operations. This is particularly useful in server environments where multiple language support is often not required.

This adjustment automates the following command:

# Configure APT to skip downloading additional languages
echo 'Acquire::Languages "none";' | sudo tee /etc/apt/apt.conf.d/99-disable-translations
        

3

Synchronize Time Automatically

This optimization configures the system to automatically synchronize its time, ensuring accurate timekeeping.

Why it's beneficial:Accurate timekeeping is crucial for many system operations, log consistency, and proper functioning of time-sensitive applications. Automatic synchronization ensures your Proxmox VE system maintains the correct time without manual intervention.

This adjustment automates the following command:

# Note: To set timezone automatically based on IP, you can use:
IP=$(dig +short myip.opendns.com @resolver1.opendns.com)
TIMEZONE=$(curl -s "https://ipapi.co/$IP/timezone")
sudo timedatectl set-timezone "$TIMEZONE"

Update and Upgrade System

This optimization updates the system's package lists, upgrades installed packages, and configures Proxmox repositories. It also includes additional steps to properly set up Debian repositories, disable certain warnings, and perform safety checks after the update process.

Why it's beneficial:Keeping your system up-to-date is essential for security, stability, and performance. This optimization ensures you have the latest patches and features, while also configuring the correct repositories for Proxmox VE, enabling access to necessary updates and tools. The disk metadata check helps prevent potential issues with storage devices that may have been modified by virtual machines.

Repository changes:

• Disabled: Enterprise Proxmox repository (pve-enterprise.list) - This repository is for users with a paid subscription.
• Disabled: Enterprise Proxmox Ceph repository (ceph.list) - This repository is for enterprise Ceph storage solutions.
• Added: Free public Proxmox repository (pve-public-repo.list) - This provides access to free Proxmox VE updates and packages.
• Configured: Main Debian repositories - These provide access to the core Debian packages and security updates.

This adjustment automates the following command:

# Disable enterprise Proxmox repository
if [ -f /etc/apt/sources.list.d/pve-enterprise.list ]; then
  sudo sed -i 's/^deb/#deb/g' /etc/apt/sources.list.d/pve-enterprise.list
fi

# Disable enterprise Proxmox Ceph repository
if [ -f /etc/apt/sources.list.d/ceph.list ]; then
  sudo sed -i 's/^deb/#deb/g' /etc/apt/sources.list.d/ceph.list
fi

# Enable free public Proxmox repository
echo "deb http://download.proxmox.com/debian/pve $(lsb_release -cs) pve-no-subscription" | sudo tee /etc/apt/sources.list.d/pve-public-repo.list


# Configure main Debian repositories
cat <<EOF | sudo tee /etc/apt/sources.list
deb http://deb.debian.org/debian $(lsb_release -cs) main contrib non-free non-free-firmware
deb http://deb.debian.org/debian $(lsb_release -cs)-updates main contrib non-free non-free-firmware
deb http://security.debian.org/debian-security $(lsb_release -cs)-security main contrib non-free non-free-firmware
EOF

# Disable non-free firmware warnings
echo 'APT::Get::Update::SourceListWarnings::NonFreeFirmware "false";' | sudo tee /etc/apt/apt.conf.d/no-bookworm-firmware.conf

# Update and upgrade
sudo apt-get update
sudo apt-get dist-upgrade -y

# Update PVE application manager
pveam update

# Install additional packages
sudo apt-get install -y zfsutils-linux proxmox-backup-restore-image chrony
