# Wireguard VPS Proxy Setup
|

# =============================================================================
|

#
|
||||
# This script automates the setup of a WireGuard VPN server on a remote VPS
|
||||
# for StartOS Clearnet functionality. It handles:
|
||||
#
|
||||
# 1. SSH key-based authentication setup
|
||||
# 2. Root access configuration (if needed)
|
||||
# 3. WireGuard server installation
|
||||
# 4. Configuration file generation and import
|
||||
#
|
||||
# Usage:
|
||||
# wireguard-vps-proxy-setup [-h] [-i IP] [-u USERNAME] [-p PORT] [-k SSH_KEY]
|
||||
#
|
||||
# Options:
|
||||
# -h Show help message
|
||||
# -i VPS IP address
|
||||
# -u SSH username (default: root)
|
||||
# -p SSH port (default: 22)
|
||||
# -k Path to custom SSH private key
|
||||
#
|
||||
# Example:
|
||||
# wireguard-vps-proxy-setup -i 110.18.1.1 -u debian
|
||||
#
|
||||
# Note: This script requires root privileges and will auto-elevate if needed.
