Eu quero fazer um backup de um Synology DiskStation (DSM 6.0.2-8451 Update 9) para um servidor CentOS6 usando o Rsync via SSH.
configuração do servidor CentOS6
/etc/rsyncd.conf
uid = root
gid = root
max connections = 10
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
auth users = synology
secrets file = /etc/rsyncd.secrets
max verbosity = 2
transfer logging = yes
[synology1]
path = /mnt/disk/synology/
hosts allow = xxx.xxx.xxx.xxx (Synology server's IP)
list = true
read only = no
/etc/xinetd.d/rsync
service rsync
{
disable = no
flags = IPv6
socket_type = stream
wait = no
user = root
server = /usr/bin/rsync
server_args = --daemon
log_on_failure += USERID
}
Um usuário do sistema chamado 'synology' também existe no meu sistema, com uma senha igual à 'synology' do usuário rsync fornecida em /etc/rsyncd.secrets.
Eu tentei isso no servidor Synology:
rsync -av /tmp/try/ [email protected]::synology1 -e 'ssh -v'
e obtenha:

rsync error: rsync service is no running (code 43) at io.c(687) [sender=3.0.9]
Ooooh, estou intrigado depois de várias tentativas e horas de googling embaçado. Poucas perguntas por minha causa!
1 / Eu realmente tenho que ter a mesma conta (usuário / senha) no meu sistema CentOS e na configuração do rsync para poder rsync via ssh?
2 / o que está causando meu " erro de rsync: o serviço rsync não está em execução " aqui? alguma ideia?
Obrigado por qualquer ajuda!
