Frp Configurator

FRP Configurator

This skill helps you set up and manage FRP (Fast Reverse Proxy) for secure intranet penetration and remote access.

Capabilities

1. Configure Local (Client): Install and configure frpc on the current machine.
2. Configure Remote (Server): Install and configure frps on the current machine.
3. Pairing / Export:
   • Export to Remote: If you have a Client config, generate a Server installer package that matches your keys.
   • Export to Local: If you have a Server config, generate a Client installer package that matches your keys.
4. Uninstall: Remove FRP services and configuration.

Tools & Scripts

Located in scripts/:

• setup_client.sh: Installs frpc, sets up systemd service, configures Web UI.
• setup_server.sh: Installs frps, sets up systemd service, configures Dashboard.
• pack_for_server.sh: Reads local frpc.toml $\rightarrow$ Generates frps_bundle.tar.gz.
• pack_for_client.sh: Reads local frps.toml $\rightarrow$ Generates frpc_bundle.tar.gz.
• uninstall.sh: Stops services and removes FRP installation.

Usage Examples

1. Setup Client (Local)

# Interactive setup
bash scripts/setup_client.sh

# Non-interactive / Automated setup (Recommended for scripts)
# This avoids the "Connection Refused" error by setting the correct server upfront.
export FRP_SERVER_IP="x.x.x.x"     # Replace with your Server IP
export FRP_SERVER_PORT="7000"      # Replace with your Server Port
export FRP_AUTH_TOKEN="my-secret-token" # Replace with your Token
bash scripts/setup_client.sh -y    # Use -y to skip prompts

2. Setup Server (Remote)

# Interactive setup
bash scripts/setup_server.sh

3. I have a Client, I need to setup the Server

# Generate server installer based on my client config
bash scripts/pack_for_server.sh
# Then upload 'frps_bundle.tar.gz' to your server and run the install script inside.

4. I have a Server, I need to setup a Client

# Generate client installer based on my server config
bash scripts/pack_for_client.sh
# Then download 'frpc_bundle.tar.gz' to your client machine and run the install script inside.

5. Uninstall

bash scripts/uninstall.sh

Configuration Details

• Default Install Path: /srv/frp
• Config Files: frpc.toml / frps.toml
• Systemd Services: frpc.service / frps.service
• Web UI:
  • Client Admin: Port 7555 (default)
  • Server Dashboard: Port 7500 (default)

Troubleshooting

Connection Refused (client/service.go error)

If you see errors like connect to server error: dial tcp 127.0.0.1:7000: connect: connection refused in the logs:

1. Check Config: Ensure serverAddr in /srv/frp/frpc.toml points to your actual Remote Server IP, not 127.0.0.1.
2. Check Logs: tail -f /srv/frp/frpc.log
3. Update Config:

   # /srv/frp/frpc.toml
   serverAddr = "YOUR_REMOTE_IP"
   serverPort = 7000 # Must match server's bindPort
   auth.token = "YOUR_AUTH_TOKEN" # Must match server's auth.token
   

4. Restart Service: sudo systemctl restart frpc

Example Configuration (frpc.toml)

serverAddr = "203.0.113.10"
serverPort = 7000

auth.method = "token"
auth.token = "secure_token_123"

# Expose local SSH (Port 22) to Remote Server (Port 6000)
[[proxies]]
name = "ssh-my-laptop"
type = "tcp"
localIP = "127.0.0.1"
localPort = 22
remotePort = 6000
