rsync error: protocol incompatibility (code 2)

[Drakx]

Hi,
I'm getting the following issues on the sender node

rsync error: protocol incompatibility (code 2) at compat.c(610) [sender=3.2.5] Unable to initiate dnsmasq.d rsync. Is the receiver online? tput: No value for $TERM and no -T specified tput: No value for $TERM and no -T specified tput: No value for $TERM and no -T specified protocol version mismatch -- is your shell clean? (see the rsync manpage for an explanation) rsync error: protocol incompatibility (code 2) at compat.c(610) [sender=3.2.5] Unable to initiate dnsmasq.d rsync. Is the receiver online?

The receiver node appears to be fine:
docker logs pihole-sync-receiver, chpasswd: password for 'root' changed Server listening on :: port 22. Server listening on 0.0.0.0 port 22.

This has only recently started to complain about rsync.

I have the same problem.

ssh: connect to host 192.168.100.11 port 22222: Connection refused
rsync: connection unexpectedly closed (0 bytes received so far) [sender]

The author made a mistake in entryPoint.sh

 rsync -a -P --exclude '01-pihole.conf' /mnt/etc-dnsmasq.d/ -e "ssh -p ${REM_SSH_PORT}" root@${REM_HOST}:/mnt/etc-dnsmasq.d/ --delete

docker-pihole-sync/entryPoint.sh

Line 62 in 662b2a8

rsync -a -P --exclude '01-pihole.conf' /mnt/etc-dnsmasq.d/ -e "ssh -p ${REM_SSH_PORT}" root@${REM_HOST}:/mnt/etc-dnsmasq.d/ --delete

It won't work for /etc/pihole/ and /etc/dnsmasq.d/ and other locations.
