 # Demonstration based on rsync protocol
 In vsftpd, there are virtual users (impersonated users customized by the administrator) because it is not safe to use anonymous users and local users. We know that a server based on the SSH protocol must ensure that there is a system of users. When there are many synchronization requirements, it may be necessary to create many users. This obviously does not meet the GNU/Linux operation and maintenance standards (the more users, the more insecure), in rsync, for security reasons, there is an rsync protocol authentication login method.

 As we mentioned earlier, one-way synchronization uses rsync + inotify-tools. In some special usage scenarios, two-way synchronization may be required, which requires inotify-tools + unison.
