Restricted User Shell
In this chapter we will explain how to write GNU Rush configuration rules for several popular remote copy and version control system utilities. For this purpose, we assume the following setup:
rsyncto upload files to the /incoming directory and to copy files to and from their ~/public_html directory. The actual location of the /incoming directory is /home/ftp, but that must be transparent to users, i.e. they use
scp file host:/incoming(not
host:/home/ftp/incoming) to upload files.
sftpto manage their ~/public_html directory. In this case, to prevent users from accessing other directories,
sftp-serveris executed in a chrooted environment.
