This patch has been around for several years. I used to be more diligent about maintaining it but lately I have been slacking off. I'll try to release updates when new versions of openssh appear, but no guarantees.

patch for openssh that allows a system administrator to set the umask on sftp sessions and to control whether the client may issue chown and chmod commands in an sftp session. You may optionally designate a umask that overrides any server, client or environment umasks. This is useful in cases where you want to enforce a strict file creation mode and you want to prohibit users from being able to change file permissions on existing files. An example is a web development server that contains a common folder where many users upload and modify content. The chown/chmod feature is useful in cases where you want to prohibit ftp clients from changing ownership of public area files.

This patch supersedes the popular sftplogging patch for openssh versions 4.4p1 and higher.

This patch is designed for Unix-based operating systems.
