Although I’ve used ColdFusion for 7+ years now, I’ve never used the cfftp tag before. Yesterday, I found a reason to try it out. I figured it would be as simple as cfhttp–and it was, with one exception (no pun intended).<\/p>\n

Here is my sample code:<\/p>\n

<cfftp action=\"open\" \r\n    connection=\"test\"\r\n    server=\"ftp.osric.com\"\r\n    username=\"chris\"\r\n    password=\"********************\"\r\n    timeout=\"60\"\r\n    stoponerror=\"yes\">\r\n<cfftp  \r\n    connection = \"test\" \r\n    action = \"getFile\"  \r\n    name = \"downloadFile\"  \r\n    transferMode = \"binary\"  \r\n    localFile = \"S:\\chris\\handlebar-moustache.jpg\"  \r\n    remoteFile = \"handlebar-moustache.jpg\"\r\n    timeout=\"60\"><\/code><\/pre>\n
Here’s the error message it produced:
\nAn error occurred during the FTP getFile operation.
\nError: getFile operation exceeded timeout.<\/code><\/p>\n
However, the local file was still created (as a zero-byte file).<\/p>\n
The solution, in my case, was to turn on passive mode (add attribute passive=\"yes\"<\/code> to the cfftp tag).<\/p>\n
