Iridium server, logic machine and ssh

[Geekhouse]

Hi Guys,
i have installed iridium server in the logic machine, server seams to run but when i type http://host:8888/  (which should be the right path as wrote at iridiummobile site) the system shows a blank page.

So i tried to access by ssh in the way to test if the iridium server was installed properly but i cannot get the access done.
As i read ssh is closed by default, but how can i do to check and login the server?

Any clue =?

Thank you in advance
