Overview

goflyway v2 - a local port forwarder built on HTTP

master is the active develop branch and containing v2 code, for the stable v1 release (though it was once called v2.0), please refer to v1.0 branch.

goflyway v2 is a special tool to forward local ports to a remote server securly, just like ssh -L.

goflyway uses pure HTTP POST requests to relay TCP connections. There is no CONNECT involved nor needed because goflyway is designed mainly for those people who are behind a CONNECT-less HTTP proxy or want to accelerate connections through static CDNs.

However pure HTTP requesting is definitely a waste of bandwidth if you already have a better network environment, so use -w to turn on WebSocket relay, or -K to turn on KCP relay if possible.

Usage

Forward localhost:1080 to server:1080 through server:80

    Server: ./goflyway :80
    Client: ./goflyway -L 1080::1080 server:80 -p password

Forward localhost:1080 to server2:1080 through server:80 using WebSocket

    Server: ./goflyway :80
    Client: ./goflyway -w -L 1080:server2:1080 server:80 -p password

Dynamically forward localhost:1080 to server:80

    Server: ./goflyway :80
    Client: ./goflyway -D 1080 server:80 -p password

HTTP reverse proxy or static file server on the same port:

    ./goflyway :80 -P http://127.0.0.1:8080 
    ./goflyway :80 -P /var/www/html

Write Buffer

In HTTP mode when server received some data it can't just send them to the client directly because HTTP is not bi-directional, instead the server must wait until the client requests them, which means these data will be stored in memory for some time.

You can use -W bytes to limit the maximum bytes a server can buffer (for each connection), by default it is 1048576 (1M). If the buffer reaches the limit, the following bytes will be blocked until the buffer has free space for them.

    疑似ssl证书问题

    系统版本 win10 pro，goflyway版本1.2.0a/1.1.0a，之前都使用正常，直到昨天重新全新安装了win10 pro。发现goflyway不正常，google，youtube无法访问，在chrome里提示ERR_CONNECTION_CLOSED，在firefox则是提示服务器响应时间过长，ca.pem已导入了中间证书后，仍然无法正常。 同时注意到，如果是无ssl证书的地址如www.wenxuecity.com，则可以通过goflyway代理正常访问。
