I have rsync running on a NAS200 under Jac0's alternative firmware. Installing To install rsync: Install Jac0's alternative firmware and set up ssh as per the instructions Download rsync.tar and copy it to your NAS200 Log into your NAS200 and untar the file in the root directory Reboot your NAS200 Using There are two ways of rsync'ing: 1. rsync protocol (unencrypted) rsync -av --stats files email@example.com::disk1 You will need to provide an rsync module password (see below) 2. rsync over ssh (encrypted but 5 times slower) rsync -av --stats -e "ssh -l root" --rsync-path=/harddisk/volume_1/conf/bin/rsync files firstname.lastname@example.org::disk1 You will need to provide both the root password and an rsync module password (see below) where files are the files you wish to rsync and 192.168.1.1 is the IP address of your NAS200 Note: It doesn't seem possible to set up a user to have both ssh and web/ftp access. Configuration There are two configuration files: /harddisk/volume_1/conf/rsyncd.config Configuration information for rsyncd. One rsync module is set up: disk1 /harddisk/volume_1/conf/rsyncd.secrets Username and password for the modules. Default is admin:admin Note To be accessible from the Linksys web interface, files need to be group readable. You may need to use the either "--chmod=Dg+x,g+r" on the client side or add "incoming chmod = Dg+x,g+r" in the rsyncd.conf file for the module.
