Hi, 

I do not have an easy answer for you. 
No, you don���t need to install ssh-agent. 
But then, I do not understand why you can���t connect, since others have not reported this problem, I just can guess: is your key password protected? 
Has you provided it?

Also, password protected keys has had problems in the past, I would suggest to use one that does not have.

I followed the tutorial and provided IceCredentialProvider with ssh settings, also put the same settings in Settings-Tools-Software Configuration Management. 
It seems not to have any effect since when I try to create a repo using SSH it gives the error "Failed to connect to github.com".
I need to get past that error since I get it even when I install Moose via Metacello.
Do I need to add ssh-agent as well? If yes, why do we need to provide public/private key paths with IceCredentialProvider?
