ssh non connette con publickey, solo password

[beppe <gitrec@tin.it>]

dal client ho provato sia dsa che rsa:
$ ssh-keygen -b 1024 -t dsa -f /home/beppe/.ssh/id_dsa_beppe
scp /home/beppe/.ssh/id_dsa_beppe.pub  
beppe@192.168.240.100:/home/beppe/.ssh/id_dsa_beppe.pub

$ ssh-keygen -b 2048 -t rsa -f /home/beppe/.ssh/id_rsa_beppe

e non riconosce la passphrase messa, serve la password.

Ovviamente le chiavi erano state copiate tutte nel file autorized_keys,
sia da sole che con altre, ma non ha mai funzionato.

qualche suggerimento?

ciao
