checkout your rsync configuration as follows:

$ sudo vi /etc/xinetd.d/rsync

service rsync
{
        disable = yes
        flags           = IPv6
        socket_type     = stream
        wait            = no
        user            = root
        server          = /usr/bin/rsync
        server_args     = --daemon
        log_on_failure  += USERID
}

and change `disable` from `yes` to `no`.

Restart the xinetd as follows:

$ sudo /etc/init.d/xinetd restart
