rsync: if a module is not found, what can I check? I am trying to simply copy a file from 192.168.1.225 to 192.168.1.228 I'm executing the following command from a ubuntu VM at ip 192.168.1.228. (I'm trying to do a **_pull_** , if i'm not wrong in the term) rsync rsync://realtebo@192.168.1.225/pihole_conf/black.list /etc/pihole/black.list In the .225 I created the pihole_conf as follows realtebo@192.168.1.225$ cat /etc/rsyncd.conf [pihole_conf] comment = Pihole configuration path = /etc/pihole auth users = realtebo hosts allow = * hosts deny = * list = false This is the error @ERROR: Unknown module 'pihole_conf' rsync error: error starting client-server protocol (code 5) at main.c(1666) [Receiver=3.1.2] I'd like an help to understand the source of the problem.

You are both allowing and denying all possible hosts from that module.

Remove the `hosts deny = *` line and it should work.

You do have a `secrets file` defined, I hope, which contains the allowed user and the corresponding password. It looks like you don't, but perhaps you redacted some of the rsyncd.conf contents without telling us.
