./cockpit.sh
A Window will be opened. Refer the screenshot.

Now enter the accesskeys / Secret keys from Eucalyptus Portal and click Login.

Now you see a progress screen, validating the Credentials

After successful login,you will get a similar screen shown below, where you can create / delete  bucket, change ACL for a bucket.

To make an object in a bucket to be  accessible to every one, you need to give full ACL to the Object and the Entire bucket.

Next right click on the particular object and select "Generate public GET URL".

Now you need to copy the URL and paste in a browser.

You will be able to download the object from the bucket.
