There's some FTP code posted but here's a basic SFTP version. Feel free to correct me or add to it and post.

Some elements actually might not be needed or could be better written.

I'm not a programmer per se so be nice.....

There's a minor bug with that code when running under Windows. Once the file is uploaded it's left in a locked state. If you're running a process involving an export and upload you'll then get an error 800 from FileMaker as it can't overwrite the file.

Here's a slightly revised version that corrects the issue and works correctly cross platform. On line 40 it creates a FileInputStream that is explicitly closed once the upload is done.

I have tried to use this but after a long wait I get the result 'null' and no file transfer occurs.

I have local directory paths in the formats /Users/username/Desktop and /Users/username/Desktop/ and similar formats for the remote directory path.

Anyone give me any pointers, the hostname, port, username and password are all correct

Thanks

Tim

Tim,

It's not a certainty, but the problem is most likely caused by the server being set for key authentication and NOT password authentication. Can you connect to it with Filezilla or other sftp client software? You may need to add key authentication to the code provided. In you client software, are keys set (e.g. in Filezilla, Settings|SFTP|Private keys)?
