Rsync hang. Mengapa?

Saya mencoba rsync file dari Ubuntu saya ke router mini Xiaomi memiliki firmware padavan

rsync -vvv --rsync-path="/opt/bin/rsync" ~/somefile root@router:/etc/storage/dnsmasq/

Tapi itu hang, memberi saya yang berikut:

opening connection using: ssh -l root router /opt/bin/rsync --server -vvve.Ls . /etc/storage/dnsmasq/  (9 args)
[sender] make_file(somefile,*,0)
send_file_list done
send_files starting
server_recv(2) starting pid=633
recv_file_name(somefile)
received 1 names
recv_file_list done
get_local_name count=1 /etc/storage/dnsmasq/

lokal: rsync versi 3.1.0 protokol versi 31

jarak jauh: rsync versi 3.1.2 protokol versi 31
