Hey guys,

I can neither call the web interface over the internet nor log in via SSH.

I get the following error message with ssh -vv pi@anonym.duckdns.org

OpenSSH_6.6.1, OpenSSL 1.0.1f 6 Jan 2014

Can someone help me with this Problem? :slight_smile:

To see what’s wrong: would you please check (and probably post) the server’s ssh config. Do you have password ident enabled? If you don’t - where did you put the public key of your client to? You took the clients’s public key to the server do you :slight_smile:

Not sure but I think you have a routing problem. The ipv6 address with only zeros afaik refers to the loopback interface, so afaics you are trying to connect to your own machine.

Figure out a the real ip address and then try a
telnet 1.2.3.4 22
to check is the ssh service is listening to this port. 1.2.3.4 being the ipv4 or ipv6 address of your server of course.
