Rsync 服务无法使用

xuchunyang commented 6 years ago

https://status.emacs-china.org/778801282 提示 Rsync 服务从今天凌晨起无法连接，我登入服务器确认了 Rsync daemon 正常运行

但是从外网却依旧无法访问，下面两个命令均卡住

~ $ rsync -av --list-only rsync://elpa.emacs-china.org/elpa/
~ $ nc -zv elpa.emacs-china.org 873

不知为何。暂时先等到明天，或许是阿里云的问题。

@zilongshanren 我们这台服务器的 873 端口好像被封锁了，阿里云是不是有什么端口白名单机制？你能不能帮忙看看？

xuchunyang commented 6 years ago

/ping @zilongshanren

netstat能看到监听873吗？

@lujun9972 能

@zilongshanren 能不能请你看看是不是阿里云封锁了 873 端口？
