Name

kcpraw - an useful fork of kcptun

Synopsis

$ kcpraw_client_darwin_amd64 -l 127.0.0.1:1080 -r vps:80 --key secret --mode fast3 --mtu 1200 --ds 0 --ps 0 --nocomp --host www.zhihu.com   
# kcpraw_server_linux_amd64 -l vps:80 -t :10086 --key secret --mtu 1200 --mode fast2 --ds 0 --ps 0 --nocomp

Features

turn udp traffic to tcp traffic
http obfuscating
easy to install & build & use
provide socks5/socks4/socks4a/http & shadowsocks server at kcpraw/server
support socks5 udp-associate
provide additional tcp/udp tunnels
aggregate multiple underlying connections to one kcp connection

Installation

It is highly recommended to use kcpraw releases.

Note for Windows Users
kcpraw is dependent on winpcap.You should download and install it from winpcap first.

Note for Linux Users
kcpraw uses raw-socket to receive and send tcp packets. root permission is required.

Note for Macos Users
kcpraw requires read permission for /dev/bpfx. so don't run kcpraw as nobody.

Build

Alternatively, you can manually compiled it from source:
1.Download and install Go from https://golang.org/dl/ if you don't have go yet.
2.Run go get or build.sh

$ go get -u -v github.com/zhengying/kcpraw/kcpraw/client
$ go get -u -v github.com/zhengying/kcpraw/kcpraw/server  

# or 
$ go get github.com/zhengying/kcpraw/kcpraw  
$ cd $GOPATH/src/github.com/zhengying/kcpraw/kcpraw  
$ ./build.sh

Note for Windows Users

If you're trying to compile 64-bit kcpraw(or google/gopacket) on 64-bit Windows, you might have to do the crazy hijinks detailed at compile gopacket on windows
