LIST 上的 ProFTPd 超时

  • 772

最近我将一个 centOS 5 服务器迁移到 7。但从那时起，除非我将 FileZilla 放在 FTP 普通连接上，否则通过 FileZilla 连接到 FTP 不起作用。

获取文件夹列表时 TLS 不起作用登录工作正常。但在那之后它超时了。

到目前为止，我唯一能找到的就是将它添加到 proftpd.conf

  <IfModule mod_facts.c>
    FactsAdvertise off
  </IfModule>

这会将命令更改为 LIST 而不是 MLSD。然而它仍然无缘无故超时。有人有什么主意吗？

编辑：没有 TLS 连接工作正常

    看：

    ProFTPD - 使用 TLS 时无法检索目录列表

    可能是你和服务器之间防火墙的相关规则有问题。
