[Wien] ssh bruteforce attempt from public.metalab.wien.funkfeuer.at

[Gui Iribarren]

yesterday while debugging the RST thing, i also spotted a flood of these
in the log. circa 17 attemps per minute, lasted for at least a couple of
hours. here two example lines only:
Sun Apr 22 18:42:33 2018 authpriv.warn dropbear[29515]: Bad password
attempt for 'root' from 78.41.112.151:44084
Sun Apr 22 19:02:29 2018 authpriv.warn dropbear[30205]: Login attempt
for nonexistent user from 78.41.112.151:47361

i'm pretty used to seeing that kind of bruteforce attempts "from the
wild" out in the internet, but in this particular case,
that ip resolves to public.metalab.wien.funkfeuer.at

possibly just someone experimenting at the metalab (seems to have
stopped today). but reporting just in case.
