File not found : / (code=2)

Question

Hello,
I am trying to make connection to SFTP site (with server validation off) and I am getting "File not found : / (code=2)" error message after I have made a connection and try to get file listing by calling GetFiles()? Any idea why I am getting this error message? I am getting same error message if I try running from Examples! Let me know if you need anything else.

Below is the DEBUG log...

Answer 1

It's trying to list the root directory, which you probably don't have permission to list.

Do you know what directory you should end up in?

You could set ServerDirectory = "/home/mydir" (or to whatever your home dir is).

Answer 2

On the server, we do have home directory set to some folder! I thought when I log in, it should put me in the home directory! I tried setting ServerDirectory as you specified, but not luck. Also, right after connecting, I tried Changing the working directory (ftpConnection.ChangeWorkingDirectory("/folder1/");), but I get the same error. I tried connecting to the same using third party FTP tool and it is able to connect fine!

Answer 3

So are you using

ftp.ServerDirectory = "/folder1/";

?

Answer 4

Could you try logzilla, and post the log file of what happens when you log in? that should help figure out the problem.
