goflyway

goflyway, HTTP tunnel in Go

goflyway is a tunnel proxy helping you fly across the wall. It is based entirely on HTTP protocol without any other 3rd party libraries.

中文

Build & Run

Download the binary from releases, on your VPS, launch the server by:

./goflyway -k=KEY

where KEY is the password, then at local run the client to connect:

./goflyway -up=VPS_IP:8100 -k=KEY

Set your Internet proxy to 127.0.0.1:8100 (HTTP or SOCKS5 protocol) and enjoy.

Build from source

$ go get -u github.com/coyove/goflyway/cmd/goflyway
$ goflyway -k=KEY

Usage as a docker image

If you want to do it through Docker (if you don't have/want go installed on your local):

make -f docker.Makefile clean build

Docker image can be built with:

make build_image

It's a multi-stage build so the size is ~8.23mb

❯ docker images | grep goflyway
coyove/goflyway                      latest                       68bd9fe5612e        7 minutes ago       8.23MB

Can be used like:

❯ docker run --rm -p 8102:8102 -p 8100:8100 -p 8101:8101 coyove/goflyway -debug

[W 0912 22:44:16.696] [WARNING] you are using the default key, please change it by setting -k=KEY
[  0912 22:44:16.696] debug mode on, port 8100 for local redirection, upstream on 8101
[  0912 22:44:16.696] listening on :8102
[  0912 22:44:16.697] socks5 proxy at :8101
[  0912 22:44:16.697] http proxy at :8100, upstream is 127.0.0.1:8101

UDP

We have an experimental SOCKS5 UDP relay, turn it on (both at client and server):

./goflyway YOUR_OTHER_COMMANDS -u 8731

note that the listening port (8731 in this example) should be identical at both sides.

goflyway (only) uses TCP to relay UDP, which is bound to be slow. Use the flag -udp-tcp N and increase N progressively (default 1) to tweak the performance.

UDP relay is only tested under a limited number of programs (Skype, Discord, etc.) using SocksCap64, problem reports are welcome. (BTW, dnscrypt is not working)

Console

There is a simple web console for client built inside goflyway: http://127.0.0.1:8100/?goflyway-console.

Others

When comes to speed, goflyway is nearly identical to shadowsocks. But HTTP has (quite large) overheads and goflyway will hardly be faster than those solutions running on their own protocols. (If your ISP deploys QoS, maybe goflyway gets some kinda faster.)

However HTTP is much much easier to write and debug, I think this trade-off is absolutely acceptable. If you need more speed, try KCPTUN, BBR, ServerSpeeder...

Android

Currently there is no client on Android, here is a workaround:

1. Install Termux and launch it
2. pkg install golang
3. go run main.go -k=KEY -up=VPS_IP:8100
4. Connect to your WIFI and set its proxy to 127.0.0.1:8100

Works on my XZP Android 7.0
