Hi again
I am trying to connect to my Leap 42.2 machine using filezilla from a opensuse 13.2 machine using filezilla I get a “Connection Refused”. On the Leap 42 machine I checked the logs using journalctl -j and this is the message:

Permission 640 for '/etc/ssh/ssh_host_xxxxx_key' are to open. It is required that your private key file are NOT accessible by others. This private key will be ignored. key-xxx-private bad permissions could not load host key:/etc/ssh/ssh_host_xxxxx_key' kex protocol error type 30 seq 1 [preauth]

As always, your help is very much appreciated

Well, the message says that the permissions on /etc/ssh/ssh_host_xxxxx_key are wrong (it should have read access for the owner only). And the message also says the are 640, which is read rw-r----- and thus read access for the owner and the group Thus the first thing is to check is those permissions are read;y so:

ls -l /etc/ssh/ssh_host_xxxxx_key

And when yes to remove the r bit from the group permissions.
