    这是一个创建于 454 天前的主题,其中的信息可能已经有所发展或是发生改变。
    登录我们单位自建的 ftp 时(应该是阿里云),提示连接已经建立( connection established ),然后连接又被关闭了( closed by server ),是不是 ftp 服务那边的问题?跟我这边没啥关系吧?
    管理员在国内,说他可以登录,我在国外用的星链。

    肯定有啊,不然谁都能来试密码?
    你先问问是否需要特定客户端,是否需要 ftp-ssl ,以及账密的加密方式

    有的 ftp 会限制同一 ip 的连接数,限制密码尝试次数

    估计是防火墙相关的问题

    最好是有一层 tls 的 ftps 、sftp 或者 WebDAV ,推荐 WebDAV

    好像有些阿里云的国内服务器会墙掉国外 IP

    FileZilla 的[主动,被动]模式切换试试

    @frank553000 这明显和主动被动无关啊
