# This script installs and configures XRDP with XFCE on a Debian system.
#
# It performs the following steps:
# 1. Updates the system packages.
# 2. Installs XRDP.
# 3. Installs the XFCE desktop environment.
# 4. Configures XRDP to use XFCE by creating a .xsession file in the home directory.
# 5. Checks if the XRDP_PORT environment variable is set:
#    - If XRDP_PORT is set, it configures XRDP to use this port.
#    - If XRDP_PORT is not set, it defaults to port 3389.
# 6. Updates the XRDP configuration to use the specified port.
# 7. Restarts the XRDP service to apply the changes.
# 8. Configures the firewall to allow traffic on the specified XRDP port.
# 9. Checks the status of the XRDP service to ensure it's running properly.
#
# Usage:
# - Save this script to a file, e.g., setup_xrdp.sh.
# - Make the script executable: chmod +x setup_xrdp.sh
# - Run the script with superuser privileges:
#   sudo ./setup_xrdp.sh
# - Optionally, set the XRDP_PORT environment variable to specify a custom port:
#   sudo XRDP_PORT=3390 ./setup_xrdp.sh

# Function to check if XRDP_PORT is set
check_xrdp_port() {
    if [ -z "$XRDP_PORT" ]; then
        echo "XRDP_PORT is not set. Using default port 3389."
        XRDP_PORT=3389
    else
        echo "Using XRDP_PORT from environment: $XRDP_PORT"
    fi
