有人知道这是什么问题吗？

谢谢！

你在路由器上部署server端？

[weiyu99]

@braveguywallce 是呀

[braveguywallce]

为什么在路由器上部署server端？你打算怎么用kcptun?

[weiyu99]

路由器放台湾，上面跑 kcptun + ss

arm架构啊，kcptun放在服务器没错。
不过这个运行命令好像和官方的不一样，官方是：./server_linux_amd64 -t "127.0.0.1:8388" -l ":4000" -mode fast2

[weiyu99]

不是命令执行问题，我在 router 上面有跑 ss-server 端口 1234, 我把 target 改成 "127.0.0.1:1234" 也是报同样的错。最后改成 "router ip: 1234" 才解决的，不懂为何 127.0.0.1 就不行。

[RubberBoy]

应该是监听端口设的是 ip:1234,而不是 0.0.0.0:1234

[gitbufenshuo]

监听 127.0.0.1 只有在你本机 connect 127.0.0.1 :1234 , 在别的地方如何 connect 127.0.0.1 。写成 0.0.0.0 就好了，就是监听所有本机 IP了。在另一台服务器上就可以 connect 通了。

[zeanzhou]

More specifically, it's due to the misconfiguration of ss. The config file of ss should be

{
"server":"0.0.0.0",
"server_port":PORT,
"local_address": "127.0.0.1",
"local_port":1080,
"password":PASSWORD,
"timeout":300,
"method":"rc4-md5"
}

Then your ss is listening to all IPs attached to your VPS, and now you are able to set target in kcptun like

127.0.0.1:PORT
