来自热心用户jch12138 的测试:

linux 端尝试运行，也连接不上，下面是报错:

ERROR: Unable to become root [1/Operation not permitted]

这个报错应该是权限问题，因为要创建虚拟网卡，需要 root 权限，启动的时候用 sudo 试试；

sudo systemctl restart happynedge

chenway

加了 sudo 确实成功了

虽然启动了，但是没有成功加入子网，下面是我的云服务器的log

但是手动ping这个域名是可以ping通的

happynsupport

chenway 这个情况好像没有遇到过，应该是edge没有正常解析这个域名；

可以先直接用服务器ip试试，修改配置文件:

sudo vim /etc/edge.conf

把
-l=vip00.happyn.cc:30025
替换为ip:

-l=45.78.59.70:30025

然后重启服务试试:

sudo systemctl restart happynedge

chenway

成功了

chenway 域名解析的这个问题还需要再研究一下，客户端连接supernode时的DNS行为貌似不是很正常...

IOS端，我只能说N2N本身是支持的，但是现在还没有IOS程序员😅，要做成界面易用的APP还需要很长时间，短时间内恐怕支持不了；

Android有现成的开源项目hin2n，近期会提个PR，让其兼容Happyn；

2022-03-31 更新；

Linux最新版已经解决此问题，请到此下载最新安装包覆盖可执行文件，重新启动服务即可；

chenway

还是想问一下，ios端以后会有吗🤩

chenway

happynsupport okok，我看看有空能不能学一点，自己写一个哈哈哈

更新：

现在国内域名已经备案完毕，为了负载均衡，请不要直接用ip连接；已有的ip会动态变化；

请用后台设定的域名+端口连接，如果连接有问题请论坛或工单反馈；
