- Implement client bandwidth limitation parameter --bandwidth, supporting 1M, 1MB, 1G and other formats - Added parseBandwidth function to parse bandwidth values and verify them - Added bandwidth limit option in HTTP, HTTPS, TCP commands - Pass bandwidth configuration to the server through protocol - Add relevant test cases to verify the bandwidth analysis function feat(server): implements server-side bandwidth limitation function - Add bandwidth limitation logic in connection processing, using token bucket algorithm - Implement an effective rate limiting strategy that minimizes the bandwidth of the client and server - Added QoS limiter and restricted connection wrapper - Integrated bandwidth throttling in HTTP and WebSocket proxies - Added global bandwidth limit and burst multiplier settings in server configuration docs: Updated documentation to describe bandwidth limiting functionality - Add 2025-02-14 version update instructions in README and README_CN - Add bandwidth limit function description and usage examples - Provide client and server configuration examples and parameter descriptions

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)
|
|
drip tcp 22 --bandwidth 1M Limit bandwidth to 1 MB/s
|
|
|
|
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.`,
