[?] DYNDNS host vulnerability

Hello all,

it's convenient to use a DYNDNS domain name like myhost.dyndns.org.
I guess, though, that the host myhost.dyndns.org would be much
more vulnerable as for crackers there is no need to watch out
for a dynamic IP that changes every day (at least in Germany).

Background: Every now and then I do some administration on a
server of a friend via

name@xxxxxxxxxxx

It would be nice to do this instead via

name@xxxxxxxxxxxxxxxxxxxxxxx

so there would be no need to let me know which dynamic IP his
router currently uses. This is what DYNDNS is supposed to do.
Nevertheless, if a cracker tries to crack into a host, he
would be happy not to care for dynamic IPs. Rather he would
be happy to rework on "friends_host.dyndns.org" without
caring for IP changes.

Am I correct or did I miss something?

If I were correct, weak login names and passwords would
be no problem, even with ssh - right?

Thanks and regards,
Frank
