I have a portal underdevelopment.What I want is that the file should be uploaded to an SFTP server.

Hello there,
I have a portal underdevelopment.
Am using FileField() to upload files and when this is successful it logs it in database and as well upload the file to a root directory of my application.
What I want is that the file should be uploaded to an SFTP server.

How do I go about this.

Thanks for you help in anticipation.
