Added --transport parameter to allow users to select transport protocol type: - auto: automatically choose based on server address (default) - tcp: direct TLS 1.3 connection - wss: WebSocket over TLS (CDN-friendly) Also updated client connector to support WebSocket transport, and added server-side discovery endpoint to query supported transport protocols.

var tcpCmd = &cobra.Command{
|
|
Use: "tcp <port>",
|
|
Short: "Start TCP tunnel",
|
|
Long: `Start a TCP tunnel to expose any TCP service.
|
|
|
|
Example:
|
|
drip tcp 5432 Tunnel PostgreSQL
|
|
drip tcp 3306 Tunnel MySQL
|
|
drip tcp 22 Tunnel SSH
|
|
drip tcp 6379 --subdomain myredis Tunnel Redis with custom subdomain
|
|
drip tcp 5432 --allow-ip 192.168.0.0/16 Only allow IPs from 192.168.x.x
|
|
drip tcp 22 --allow-ip 10.0.0.1 Allow single IP
|
|
drip tcp 22 --deny-ip 1.2.3.4 Block specific IP
|
|
drip tcp 22 --transport wss Use WebSocket over TLS (CDN-friendly)
|
|
|
|
Supported Services:
|
|
- Databases: PostgreSQL (5432), MySQL (3306), Redis (6379), MongoDB (27017)
|
|
- SSH: Port 22
|
|
- Any TCP service
|
|
|
|
Configuration:
|
|
First time: Run 'drip config init' to save server and token
|
|
Subsequent: Just run 'drip tcp <port>'
|
|
|
|
Transport options:
|
|
auto - Automatically select based on server address (default)
|
|
tcp - Direct TLS 1.3 connection
|
|
wss - WebSocket over TLS (works through CDN like Cloudflare)
|
|
|
|
Note: TCP tunnels require dynamic port allocation on the server.
|
|
When using CDN (--transport wss), the server must still expose the allocated port directly.`,
