tracker issue : CF-3796626

Problem Description: CFFTP LISTDIR command fails against FTP servers that do not allow the SYST command.

Steps to Reproduce:
Test against different FTP servers and you will find this does not work on FTP servers that do not allow the SYST command.

Here is code to test:
<cfscript>
ftpServer = '';
userName = '';
pw  = "";
</cfscript>
<cfftp action="open" username="#userName#" connection="myFtp" password="#pw#" server="#ftpServer#" stopOnError="no" passive="true" />
<cfoutput>
	FTP connection Open: #cfftp.succeeded#<br>
</cfoutput>
<cfdump var="#cfftp#">

<cfftp action="listdir" stoponerror="false" name="filelist" directory="./" connection="myFtp" passive="true">
<cfdump var="#cfftp#">
<cfdump var="#filelist#" label="filelist">
<cfftp action="close" connection="myFtp" stopOnError = "Yes">


Actual Result:

215 ERROR

When the LISTDIR command executes the SYST command must get executed first in order to determine the type of FTP server. I see this in regular FTP clients too. In most cases I see the 215 fail in a FTP client and the client simply ignores the response and goes on to the next command.

Here in ColdFusion CFFTP does NOT ignore the error even though the stopOnError attribute is set to false. I was able to see where the actual failure happened by using Wireshark to monitor the FTP network traffic created by CFFTP and I attached a screenshot of the error message as seen in Wireshark.



Expected Result:
Expected a directory listing



Any Workarounds:
None
