[hubert depesz lubaczewski]

hej
mam dziwny problem z ssh
jest sobie maszynka : polpot. na niej konto depesz ma klucz ssh. ten klucz
(identity.pub) jest na dwoch kontach na innej maszynce (neron) - konta:
depesz i root.
i o ile z depesz w polpot na depesz w neron wchodze bez hasla, o tyle z
depesz w polpot na root w neron juz nie.
