I am trying to setup a SFTP server, running off Ubuntu Server 11.04. I installed openssh-server to provide SSH access. What I am trying to do is make file uploads run with a suffix (.filepart or whatever), which would be removed upon transfer completion.
The flow idea is:
- User uploads
- The server starts writing
cat.jpg.filepartin the destination directory
- Once the upload completes, the server trashes the previous
cat.jpg(if any) and renames
This is to make sure that incomplete file uploads do not overwrite the existing files. Any idea on how I can do this?
