rsync: link_stat "." (in sprengel) failed: Permission denied (13)

[Andreas Moroder]

Hello,

we have a old version of rsync running since 2005.

Now I tried to sync between two new servers with rsync 3.0.7 and get the 
error

rsync: link_stat "." (in sprengel) failed: Permission denied (13)

On one server ( 192.168.10.2 ) I have rsync running as daemon and this 
rsyncd.conf

read only = true
use chroot = false
transfer logging = true
log format = %h %o %f %l %b
log file = /var/log/rsyncd.log
hosts allow = 10.53.5.12

[sprengel]
gid = nogroup
path = /data01/abteilungen/sprengelfotos/
comment = Fotos vom Sprengel
auth users = sprengel
secrets file = /etc/rsyncd.secrets

I would like to sync the files in
/data01/abteilungen/sprengelfotos/

with the directory /tmp/sync on the "client" so I started rsync as follows


rsync -r -t -p -o -g --progress 
--password-file=/etc/rsyncd.pass.sprengel 
sprengel at 192.168.10.2::sprengel  /tmp/sync

What is wrong in my configuration and why this "Permission denied error" ?

Thank you very much
Andreas
