It now also includes support for rdist, rsync, and cvs.

Rssh is a restricted shell for use with OpenSSH, allowing only scp and/or sftp. It also covers chroot jail setup instructions to lock down users to their own home directories (allow users to transfer files but not browse the entire Linux / UNIX file system of the server) as well as per user configurations. In this article series we will help you provide secure restricted file-transfer services to your users without resorting to FTP. SCP/SFTP -> SSHD -> Call sftpd subsystem -> Requires a shell -> User can login to server and run other commands. Basically OpenSSH requires a valid shell. However, this feature also grants ssh shell access to a user. You can use OpenSSH Server to transfer file using SCP and SFTP (secure ftp) without setting up an FTP server. FTP is insecure protocol, but file-transfer is required all time.
