Basic Rsync sync with Password Entry

Tested on MacOS against a Linux Mint Server with an rsyncd share.

Server Side

The Configuration for the (Linux server) Daemon once can be found in rsyncd.conf, and requires you create /etc/rsyncd.scrt containing the username and password pairs... The secrets file must not be world readable and only accessible by the daemon that runs rsync.

On Mint, You can start rsync via Systemd using:

# systemctl start rsync

Note: Systemd script is rsync or rsyncd depending on distro, and status of the script (reason for failure) can be found by executing systemctl status rsync.

'Client' Side

The execution script is written in tcl for the expect program and can be found in sync_rsync.tcl.

Please substitute username, IP address and password to fit your needs.

You can run this like any shell script by making it executable (chmod a+x sync_rsync.tcl).
