I installed the eucalyptus faststart3.4.2 iso from here http://downloads.eucalyptus.com/software/faststart/ and then I installed cloud in a box. Then creating an instance m1.small I am trying to ssh into the instance created by its IP. The VM is running and I can ping it, when ssh -i euca-demo.private 10.5.20.224 is run most probably it enters VM but asks for passphrase which I dont know because the image was given after installation that I used to create the instance. The message is
Enter passphrase for key 'euca-demo.private':
How can I enter without knowing the passphase? How to know the passphase?
