SSH nimmt keyfiles nicht an

Hi zusammen,
ich versuche gerade mein RaspberryPi so einzurichten, das ich mich über SSH ohne Passwort einloggen kann.

Dazu habe ich folgende Befehle ausgeführt:
Client:

Quellcode

 
1
2

$ssh-keygen -t rsa
$scp .ssh/akoya-linux_siggi_nopasswd.pub kodi@kodi:~/.ssh/


Bei der Abfrage nach dem Dateinahmen habe ich §akoya-linux_siggi_nopasswd" gewählt um den Schlüßel zuordnen zu können.
Bei der Abfrage nach dem Passwort hab ich einfach "ENTER" gedrückt.

Raspberry:

Quellcode

 
1
2
3
4

$cat akoya-linux_siggi_nopasswd.pub >> authorized_keys
$su
$nano /etc/ssh/sshd_config
$/etc/init.d/ssh restart


In der "sshd_config" habe ich folgendes geändert:

Quellcode

 
1
2

RSAAuthentication yes
PubkeyAuthentication yes


Versuche ich mich nun einzuloggen wird trotzdem nach einen Passwort gefragt

Quellcode

 
1

ssh -i .ssh/akoya-linux_siggi_nopasswd kodi@kodi

Hab das Problem gelöst.
Anscheinend ist der Dateiname "akoya-linux_siggi_nopasswd" zu lange.
Hab das Keyfile umbenannt nach "siggi-nopasswd" und schon klappt es.
