opentunnel-connect（开放隧道连接）

OpenTunnel Connect Skill

Connect to remote servers behind NAT using reverse SSH tunnel.

Flow

Step 1: Ask Options

Ask user:

• Username? (default: tunneluser)
• Minutes? (default: 60)

Step 2: Execute Binary

& "$env:USERPROFILE\.config\opencode\skills\opentunnel-connect\opentunnel.exe" --user USERNAME --minutes MINUTES

The binary will:

1. Read/create SSH key from ~/.ssh/id_ed25519.pub
2. Output curl command for remote server
3. Wait for user to input tunnel info

Step 3: User Runs Command

Give curl command to user to run on remote server.

Example:

curl -fsSL "https://raw.githubusercontent.com/julianponguta/opentunnel/main/connect.sh?v=$(date +%s)" | sudo bash -s -- 60 root "ssh-ed25519..."

Step 4: Get Tunnel Info

User must provide: bore.pub:PORT

Step 5: Connect with ezssh

ezssh_ssh_execute({
  command: "hostname && uptime",
  hosts: ["bore.pub"],
  port: PORT,
  username: "USERNAME",
  privateKeyPath: process.env.USERPROFILE + "/.ssh/id_ed25519"
})

On Linux/macOS:

privateKeyPath: process.env.HOME + "/.ssh/id_ed25519"

Quick Install (for users)

Users can install on their servers:

echo 'ot() { curl -fsSL "https://raw.githubusercontent.com/julianponguta/opentunnel/main/connect.sh?v=$(date +%s)" | sudo bash -s -- "${@:-60}"; }' >> ~/.bashrc && source ~/.bashrc

Then just run: ot 60 root
