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

Features beyond the v3 set depend on suitable client support. I have a list of clients some of which support the later protocol versions.

Download

The latest release is sftpserver-1.tar.gz. Having unpacked it:

$ ./configure
$ make
$ sudo make install

See man gesftpserver for further instructions.

Signatures (including git tags) are made with 8A741BEF. To verify, download both archive and signature and use commands like this:

$ gpg2 --verify sftpserver-1.tar.gz.pgp

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.
