[solved] SSH Remote Access from the Web using dyndns failed: Permission denied

Official Hardware Classic Yún

Hi

I don't really understand why I am not able to access Linino (OpenWrt-Yun) from the WEB over DynDns with ssh.

What is working:
If I connect to Linino by ssh in the local network:

ssh root@192.168.1.20
root@192.168.1.20's password: 

BusyBox v1.19.4 (2014-04-10 11:08:41 CEST) built-in shell (ash)
Enter 'help' for a list of built-in commands.

root@Yun:~#

Everything is great. I have connection to the Linux-System.

But if i try to connect over the web by using the DynDns:

ssh root@abc.dyndns.org
root@abc.dyndns.org's password: 
Permission denied, please try again.
root@abc.dyndns.org's password:

so on...

I don't get a connection to the Yun.

  • YES, I am sure to type the right passwort
  • YES, the port forwarding works (other device are also reachable)
  • YES, I tried to disable the firewall from the Linux (OpenWRT)
  • YES, I tried to make different configuration (via configfiles and Luci-Webinterface ---> I learned a lot the last days :wink: )

Ok...if I was writing this post I had an Idea...so I finished anyway this post...perhaps it will help somebody else:

I wrote a wrong dyndns-Url by making the example of this post. So I get the Idea to try the same with the actual IP-adress -> show-my-ip.de:

ssh root@92.105.147.12
root@92.105.147.12's password: 

BusyBox v1.19.4 (2014-04-10 11:08:41 CEST) built-in shell (ash)
Enter 'help' for a list of built-in commands.

Voilà...

Notice: I work with Terminal on OS X...at work on Putty.exe on Windows 7 -> same result.

It seem, that Terminal on OS X can't resolve the Dyndns-URL ?!? Just now I searched in the web...but I didn't invest a lot time. Im not enough expert in SSH -> but it seem to me, that it should be possible to use Dyndns-URL.

I am just now happy, that I find the problem. Feel free to replay and help better understand the situation.
