V2ray-core: 谁指导一下如何配置mkcp

Created on 14 Jul 2016  ·  20Comments  ·  Source: v2ray/v2ray-core

我在客户端的outbound和服务器端的inbound增加了kcp，双方的transtransport也配置了，结果就打不开，去掉这部分配置就好了。
服务器可以启动，配置文件无错误。

客户端：

  "outbound": {
    "protocol": "vmess",
    "settings": {
      "vnext": [
        {
          "address": "123.123.123.123",
          "port": 12345,
          "users": [
            {
              "id": "123-123-123",
              "alterId": 64
            }
          ]
        }
      ]
    },
  "streamSettings": {
    "network": "kcp" 
  }
  }

服务器端

  "inbound": {
    "protocol": "vmess",
    "settings": {
      "clients": [
        {
          "id": "123-123-123",
          "level": 1,
          "alterId": 64
        }
      ],
      "detour": {
        "to": "detour"
      }
    },
  "streamSettings": {
    "network": "kcp" 
  }
  }

表示无法使用kcp协议

KCP 使用 UDP 端口，请确认你的主机上相应的 UDP 端口已开放（防火墙之类）。

v2ray picture v2ray on 14 Jul 2016

防火墙默认是通行的

helloyan picture helloyan on 15 Jul 2016

I have the exact same problem as well, comodo shows that there're out packets, but no in packets, and V2ray client tried to establish many links but all of them failed, and there's no log on the server, seems that the data didn't get to the server.

default

Sherman-Liu picture Sherman-Liu on 15 Jul 2016

@helloyan 注意到你使用了动态端口，detour.to 指向的那个 outbound 也可以设置 "network": "kcp".

v2ray picture v2ray on 15 Jul 2016

不应该是客户端的outbound服务器端的inbound吗？这两个我都设置了，而且文档也说只有vmess才支持，其他两个都不是的吧

servers' outbound does not need "kcp“. try to delete it.
服务器端只有inbound和inboundDetour需要设置kcp，客户端只有outbound需要设置，其它的删除了。

@tlze Umm...I figured it out, first of all let me say thank you for your suggestion, it really helped, but that's not the most lethal yet dumb mistake I made......

In this part of the servers' config.json, oringinal one I made looks like this:

  "inbound": {
    "port": *,
    "protocol": "vmess",
    "settings": {
      "clients": [
        {
          "id": "*",
          "level": 1,
          "alterId": 80
        }
      ],
      "detour": {
        "to": "detour"
      },
      "streamSettings": {
      "network": "kcp"
      }
    }
  },

The new one, looks like this:

  "inbound": {
    "port": *,
    "protocol": "vmess",
    "settings": {
      "clients": [
        {
          "id": "*",
          "level": 1,
          "alterId": 80
        }
      ],
      "detour": {
        "to": "detour"
      }
    },
    "streamSettings": {
      "network": "kcp"
    }
  },

Did you notice the difference?

I frickin' forgot to move the "streamSettings" out of the "settings" bit fat curly braces!!!!

Damn you JSON!!!!

Could anyone show me a good json editor?...I'm exhausted...

@v2ray 大哥 mKCP可以和tcp 无缝集成 意思是 mKCP可以完全兼容TCP协议并且 mKCP<>TCP 直接通信？

sgf picture sgf on 25 Jul 2016

https://github.com/v2ray/manual/blob/master/zh_cn/chapter_03/kcp.md

mKCP 在 KCP 协议的基础上进行了一些改进，可以无缝替换 TCP。

你指的什么端口，我也是配置了无法使用KCP。V2Ray占用的端口 UDP 肯定都是放行了的。

hetykai picture hetykai on 17 Aug 2016

使用 ss+kcptun 在linode服务器上可以通信。换作vultr服务器就不行。
然后现在v2ray在linode上可以使用TCP，但mKCP使用不了。g了很多条网页，很大可能性是UDP被运营商封掉了。可为什么我ss+kcptun可以呢。真是奇怪，目前还没有找到答案。
