Hi Richard,

do you use your own key or the one provided by Karaf ?

Do the ssh client support rsa/dsa ?

Hi,

I migrated a karaf 3.0.3 installation from my old windows 7 laptop to a
windows 8 laptop.
In the new enviroment the ssh connect is no longer working.
I get the following error:

$ ssh  -p 8101 karaf@localhost
Unable to negotiate with 127.0.0.1 <http://127.0.0.1>: no matching host
key type found. Their offer: ssh-dss

Here is the debug output of ssh:
