connecting Arduino Yun to virtual machine host via ssh

Using Arduino Programming Questions

Hi guys,

I need to connecting my Arduino Yun to a linux virtual machine via ssh...
I've trying to do that with making "port forwarding" in the virtual machine settings but I'm just obtaining a "connection refused" message

Are there some others alternatives to do that? Could I do it with setting up some iptables rules in my Arduino Yun ?

Thanks in advance.

Regards.

Arthur.
