Rsync help

[fossum_13]

So I'm fairly new to rsync, but I think my server is functioning well now.

From the host I can type rsync user@192.168.2.154:: and I get both modules (Desktop, Server)

however when I try "sudo /usr/share/ebox-ebackup/ebox-remote-ebackup --full" I get,
eric@192.168.2.154's password:
root command /usr/share//ebox-ebackup/ebox-duplicity-wrapper remove-all-but-n-full 5 --force rsync://eric@192.168.2.154:873/Server --no-encryption failed.
Error output: rsync: change_dir "/home/ftp/873:Server" failed: No such file or directory (2)
 rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1526) [Receiver=3.0.7]
 BackendException: Error running 'rsync eric@192.168.2.154:873:Server/'

Command output: .
Exit value: 23
Where sometimes the part at the top where it asks for the rsync user password happens repeatedly 1-6 times before freezing in a backup state. I'd like to make sure my web-form if nothing else is filled out correctly...

I have:
method: rsync
host: 192.168.2.154 #should this be hostip/modulename ?
user: eric
encryption: disabled

Any help would be great, thanks
