Thanks for trying. As I said, it's strange because we use rsync with
dozens of upstreams but it only hangs with one site: ftp.heanet.ie.

I can try to get more info if somebody says what debug/dump options to
use. I don't have access to the server so I can only try from my side,
and I'm afraid it'll only show it's waiting for the server answer that
never arrives...
