Can you ssh into Galileo at all?
How to ssh to Galileo?
In general it probably would be a better idea to start a new thread rather than continuing an already answered thread with new sub issues. This thread was about ssh and contains some description on how to do it.
Now it looks like the thread is evolving to connectivity issues with Eclipse IDE. I'd suggest as a first step to chack ssh connectivity at all. Once you can successfully ssh Eclipse should be able to connect as well. With that I would assume everything should work fine.
So if you do have more issues pls start new threads
I know this sounds weird. I tried in another pc. Everything works well. I can ssh to Galileo.
I will try to see the difference between two pc.
