no matching host key type found. Their offer: ssh-dss



Reason for it not working is some of the older weaker SSH encryption algorithms have been disabled. You can allow ssh to use it by specifying the following option.

 -oHostKeyAlgorithms=+ssh-dss 

so whole command would look like

ssh  -o HostKeyAlgorithms=+ssh-dss root@192.168.111.4
