trojan_manager is a handy Bash utility for managing users of the Trojan VPN protocol. It helps admins quickly add/delete users, generate ready-to-use VPN config strings and QR codes, and perform basic access management on small and medium servers.

Features

• Add new users for Trojan VPN
• Generate connection URI and QR code (for fast onboarding)
• Manage users: remove, lock by date, regenerate password
• Logs all actions
• Integrates with systemd trojan service
• MIT licensed

Requirements

Note:
Place trojan_manager.sh into your Trojan installation directory, typically /usr/local/etc/trojan/.

• Bash (tested on Linux)
• jq (sudo apt install jq)
• qrencode (sudo apt install qrencode)
• systemd, trojan running as a servicegit

Quick Start

1. Copy trojan_manager.sh to a folder and make it executable:

   chmod +x trojan_manager.sh

2. Ensure dependencies are installed:

   sudo apt install jq qrencode

3. Run with root privileges, for example, to add a user:

   sudo ./trojan_manager.sh --new username

   The script will display a connection URI and a QR code for the new user.

Main Commands

• --new <user> — create a new user with a unique password
• --list — list and manage users (regenerate password, lock, delete, show QR, etc)
• --qr <user> — show a QR code for specified user
• --config <user> — print user's connection URI
• --restart — restart trojan.service
• --help — print help

Config files

• The script expects a config.json file with a password array, each entry in form "username_password"
• User metadata is kept in users.json
