ColdFusion版本9安全FTP - 无法连接 [英] ColdFusion Version 9 Secure FTP - Unable to Connect

问题描述

我想自动化目前手动完成的操作。正在使用ftp客户端Filezilla执行手动过程。这些是指令：

 在主机字段中，键入IP地址：xx.xxx.xxx.xxx。 
在Port字段中，键入990. 
在Servertype下拉列表中，更改它，以便它读取
 FTP over SSL / TLS（隐式加密）。 （注意：在Mac OSX 
版本，此选项将读取FTPS  -  FTP隐式TLS / SSL）。 
在登录类型区域中，选择正常。 
在用户名字段中，输入您的用户名。 
在密码字段中，输入您的密码。 
  

当我按照这些说明，我连接成功。这是我在ColdFusion中尝试的：

 < cfftp action =open
 connection =abc
 secure = true 
 server =something valid
 port =990
 username =something valid
 password =something valid> 
  

这是错误消息：建立sFTP连接时出错。验证您的连接属性：用户名，密码，服务器，指纹，端口，密钥，连接，proxyServer和安全（如适用）。错误：Session.connect：java.net.SocketTimeoutException：读取超时。

当我删除端口属性时，结果不会改变。当我将用户名更改为无效的时，我得到一个略有不同的错误：建立sFTP连接时出错。验证您的连接属性：用户名，密码，服务器，指纹，端口，密钥，连接，proxyServer和安全（如适用）。错误：外部主机关闭连接。

换句话说，超时被替换为有意闭包。

解决方案

您创建一个FTPS连接，而ColdFusion 9没有FTPS的本地支持，只有SFTP。感谢 abbottmw回答我能够在过去创建一个显式FTPS连接。 ColdFusion 9附带了Apache Commons库，您可以在Java级别使用 FTPSClient 。

I am looking to automate something that is currently being done manually. The manual process is being performed using ftp client Filezilla. These are the instructions:

In the Host field, type in the IP address: xx.xxx.xxx.xxx.
In the Port field, type in 990.
In the Servertype dropdown list, change it so that it reads 
 FTP over SSL/TLS (implicit encryption). (NOTE: On the Mac OSX 
 version this option will read FTPS – FTP over implicit TLS/SSL).
In the Logontype area, select Normal.
In the Username field, enter your username.
In the Password field, enter your password.

When I follow those instructions, I connect successfully. This is what I tried in ColdFusion:

<cfftp action="open"
connection="abc"
secure = true
server="something valid"
port="990"
username="something valid" 
password="something valid">

This is the error message: An error occurred while establishing an sFTP connection. Verify your connection attributes: username, password, server, fingerprint, port, key, connection, proxyServer, and secure (as applicable). Error: Session.connect: java.net.SocketTimeoutException: Read timed out.

When I remove the port attibute, the result is unchanged. When I change the username to something not valid, I get a slightly different error: An error occurred while establishing an sFTP connection. Verify your connection attributes: username, password, server, fingerprint, port, key, connection, proxyServer, and secure (as applicable). Error: connection is closed by foreign host.

In other words, the timeout is replaced by an intentional closure.

What should I be looking at in order to sort this out?

解决方案

Your creating a FTPS connection in Filezilla, and ColdFusion 9 doesn’t have native support for FTPS, only SFTP. Thanks to abbottmw answer I was able to create an Explicit FTPS connection in the past. ColdFusion 9 ships with the Apache Commons library and you can create the connection on the java level with FTPSClient.
