Green End SFTP Server
This is a free SFTP server. It should be possible to use it as a drop-in replacement for the widely-used OpenSSH SFTP server. It does not include an SSH server, but rather runs as a subsystem of one.
Announcements of new versions will be sent to sgo-software-announce, among other places.
Features
- Protocol versions 3 and higher:
- Upload and download files
- List files
- Create directories and symbolic links
- Rename and delete files
- Protocol versions 4 and higher:
- Filename encoding translation
- Text mode transfers
- String owner/group names (instead of numeric)
- Sub-second timestamps (where supported by server OS)
- Protocol versions 5 and higher:
- Extended rename semantics (e.g. atomic overwrite)
- Protocol versions 6 and higher:
- Create hard links
- Several SFTP extensions
Features beyond the v3 set depend on suitable client support. I have a list of clients some of which support the later protocol versions.

Developers
You can clone a nightly snapshot from https://github.com/ewxrjk/sftpserver. In more detail:
$ git clone https://github.com/ewxrjk/sftpserver $ cd sftpserver $ ./autogen.sh $ ./configure $ make
autogen.sh runs Automake, Autoconf, etc; once it has been run once you can generally rely on the makefiles to remake anything that needs remaking.
