Question

我正在使用Coldfusion cfftp标记建立与FTP服务器的安全连接：

<cfftp action = "open"
  username = "username"
  connection = "myConnection"
  password = "password"
  fingerprint = "xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"
  server = "xxx.xxx.xx.xx"
  secure = "yes">

这成功连接;我可以在ftp服务器上查看和下载文件。我正在试图找出它连接的端口。文档说默认情况下cfftp标记连接到端口21，因此它看起来像是连接到端口21.我可以指定port = 21或port = 22，无论哪种方式它仍然可以正常工作。

我发现令人困惑的是当我使用ftp客户端（Bitvise SSH客户端）手动建立相同的连接时。在Bitvise中，我输入与cfftp标签中相同的服务器IP地址，相同的用户名和相同的密码。但是，我必须输入“22”作为连接成功的端口。如果我输入“21”作为端口，我会收到一条消息，说连接失败。连接失败的文本如下：

14:13:29.767 Current date: 2018-04-11

14:14:47.864 The SSH2 session has been terminated.

所以我不清楚cfftp标签发生了什么（我可以将端口指定为21或22，无论哪种方式都是成功的安全连接），与Bitvise客户端发生的情况相比， port必须指定为22，否则连接失败。

看起来Bitvise必然会尝试建立SSH2会话。这是cfftp标签必须要做的，当安全=是吗？

与cfftp安全连接 - 哪个端口？
