Nach Neustart: ssh - Permission denied

[mosesjohann]

Hallo Liebe Debian-Gemeinde,

ich war gerade dabei, x11vnc (eine VNC-Verbindung zum Server) über ssh einzurichten, was auch alles super lief. Bei der stelle, an der es sich dann per rc.local selber starten sollte (automatischer start per script - Zeile bereits wieder aus rc.local entfernt), war ein Test-Neustart des Systems fällig. Seitdem kann ich mich von keinem anderem PC (Win/Ubuntu) mehr zu diesem PC verbinden, es passiert immer das gleiche:

Code: Alles auswählen

stefl@evo:~$ ssh stefl@192.168.1.19
stefl@192.168.1.19's password: 
Permission denied, please try again.
stefl@192.168.1.19's password: 
Permission denied, please try again.
stefl@192.168.1.19's password: 
Permission denied (password,publickey).

auch mit user "root" hab ich das gleiche Problem. Lokal gehts aber einwandfrei:

Code: Alles auswählen

stefl@virtual-server:~$ ssh moses@localhost
The authenticity of host 'localhost (127.0.0.1)' can't be established.

Are you sure you want to continue connecting (yes/no)? yes

Lösungsversuche:

• ssh neu installieren ( aptitude remove ssh ) ( aptitude install ssh )
• Neustart
• ssh via Synaptics komplett löschen und neu installieren
• Zeile zum Scriptaufruf für x11vnc aus rc.local wieder entfernen
• verschiedenes in der /etc/ssh/sshd_conf

Es war nur ein Neustart und trotzdem kann ich nicht mehr zugreifen. Ich bin aber mit meinem Latein am Ende und hoffe nun, dass jemand von euch Rat weiß!
