Question

cfftp secure bug?

having a wierd issue here.   i believe it may be a bug in CF.

code:

<cfftp secure="true" action="open" server="#ftpserver#" port="#ftpport#" username="#username#" password="#password#" fingerprint="#fingerprint#" connection="myftp">

<cfftp action="getfile" connection="myftp" remotefile="testfile.txt" localfile="E:\tmp\testfile.txt" transfermode="binary" passive="true"/>

throws error

An error occurred during the sFTP getfile operation. Error: File Exists: E:\tmp\testfile.txt

Folder view shows a file testfile.txt   0 bytes.  and it's locked (presumably by cf server)

It seems like the operation is creating the file stub, but has some problem writing to it, then complains that the file exists when cf created the file in the first place.

this is only in secure mode.  in regular FTP mode, code runs perfectly.

Stack trace:

coldfusion.tagext.net.SftpHandler$SftpOperationException: An error occurred during the sFTP getfile operation.

    Hah, I figured out both of my problems....

    My listDir operation was looking at a directory named "Out" but my getFile operation only said    remotefile="#name#" and thus it actually could not find the remote file.  I had to change it to     remoteFile="Out/#name#"

    Der!!!!

    I'm having a similar issue with coldfusion 10 but the suggested solution does not help me.

    I now get an error that says "The system cannot find the path foo.txt"

    With the failifexists="true" (the default setting), it creates the file with zero length then fails.  With failifexists="false", it doesn't seem to create the file at all and just errors on filenotfound.

    I am doing CF Lockdown - but the coldfusion user absolutely has change privileges to that folder.

    True adding failIfExists="false" to your getFile command

    well I'll be.....that "fixes" it.    i still don't see why it fails in the first place though.

    Because it is designed to work that way. FailIfExists defaults to yes. I suspect it is a fail-safe to keep from accidentally overwriting files. It would be easy enough to wrapp in a try/catch to handle. But it is not a bug. It works that way by design and is documented.

    additionally.  running CF 9.0.1      CF user definitely has write permission since regular FTP works.       Tried with a production SFTP server (Fedex)  and local SFTP server (FreeFTPd)   

    thanks
