I have downloaded the Amazon AWS SDK for C#, I have no problem accessing the EC2 part of our private cloud running Eucalyptus, I can list, Images, Instances, Zones ...

This is working fine :

AmazonEC2 ec2 = AWSClientFactory.CreateAmazonEC2Client("abcdefghijklmnopqrstuvwxyz1234567890", "abcdefghijklmnopqrstuvwxyz1234567890", new AmazonEC2Config().WithServiceURL("http://10.140.54.12:8773/services/Eucalyptus"));

DescribeInstancesRequest ec2Request = new DescribeInstancesRequest();
try
{
    DescribeInstancesResponse ec2Response = ec2.DescribeInstances(ec2Request);
    int numInstances = 0;
    numInstances = ec2Response.DescribeInstancesResult.Reservation.Count;
    textBoxInstancesLog.AppendText("You have " + numInstances + " running instances");
    textBoxInstancesLog.AppendText(ec2Response.ToString());
}
catch (Exception ex)
{
    MessageBox.Show(ex.ToString());
}

But I need to access the Walrus (S3) part of our Cloud. This is how I try to access the Walrus, the code is almost identical, but with this call I will get an exception.

This is not working:

AmazonS3 s3 = AWSClientFactory.CreateAmazonS3Client("abcdefghijklmnopqrstuvwxyz1234567890", "abcdefghijklmnopqrstuvwxyz1234567890", new AmazonS3Config().WithServiceURL("http://10.140.54.12:8773/services/Walrus"));
ListBucketsRequest s3Request = new ListBucketsRequest();
try
{
    ListBucketsResponse s3Response = s3.ListBuckets(s3Request);
    textBoxS3Log.AppendText(s3Response.ToString());
}
catch (Exception ex)
{
    MessageBox.Show(ex.ToString());
}

I will receive this exception :

System.Net.WebException: The remote name could not be resolved: 'http'
   at Amazon.S3.AmazonS3Client.processRequestError(String actionName, HttpWebRequest request, WebException we, HttpWebResponse errorResponse, String requestAddr, WebHeaderCollection& respHdrs, Type t, Exception& cause)

From Eucalyptus site :

Eucalyptus implements an IaaS (Infrastructure as a Service) private cloud that is accessible via an API compatible with Amazon EC2 and Amazon S3

What am I missing ?

Note: The same code work flawlessly with Amazon S3, the problem is to access Eucalyptus Walrus.

CentOS 5.5 is using the old python 2.4 ! But I want to install Twisted on it ! Does anyone maintain a RPM of this library ?

I am trying to setup a new UEC Cloud network using Ubuntu UEC 10.10, but I am having some difficulties with the Node Controller setup !

I am working (for the moment) on a small setup, using two computers. The first one, for CLC, CC, Walrus and SC. Second computer to be used as NC.

I am doing fresh and clean re-installation of everything.

My problem is that the NC do not have any access to the internet after its installation. As if the CC's computer would not do any forwarding from the private network to the public network. I cant finish the setup, I cant update/upgrade the NC. I can't apt-get install ntp.

If the NC can't talk to the internet, I will see the same problem with the instances too. From the NC, the only computer I can ping is the CC, using its private and public address.

Why would the CC block the NC access to internet ?

Note that I don't have these problems on Ubuntu 10.04 (using the same hardware), but I really need to be on Ubuntu 10.10.
