This works for me:

use chroot = false
strict modes = false
hosts allow = 192.168.232.103
log file = rsyncd.log
fake super = yes

[test]
path = /cygdrive/d/public
read only = false
transfer logging = yes
UID = 0
GID = 0
fake super = yes

[etel]
path = /cygdrive/d/public/etel
read only = false
transfer logging = yes
UID = 0
GID = 0
fake super = yes


/root/bin/rsync-novanished.sh -vrltH --delete --stats -z -D --numeric-ids
