[one-users] ec2 access problem after upgrading to ONE 3.0

[Daniel Molina]

Hi Ulrich,

The snippet of code I sent you just represent the client
configuration. This is the full code I used to do a request to the
OpenNebula Cloud using the Perl Client:

https://gist.github.com/3239f16e320fd9f2df61

I will send you an account to test this code in your machine, doing a
request to the OpenNebula Cloud.

I think maybe the problem is related to the port in which the
econe-server is listening (8443) different from the default one. Try
changing this line in the server code:

system-wide installation: /usr/lib/one/ruby/cloud/econe/EC2QueryServer.rb
self-contained installation:
$ONE_LOCATION/lib/ruby/cloud/econe/EC2QueryServer.rb

@@ -71,7 +71,7 @@ class EC2QueryServer < CloudServer

         econe_port = @config[:port]

-        params.merge!({:econe_host => econe_host, :econe_port => econe_port})
+        params.merge!({:econe_host => econe_host, :econe_port => 8443})
         super(env, params)
     end

And the following econe-server configuration (econe.conf). Remember to
restart the service after these changes:

# Host and port where econe server will run
:server: localhost
:port: your_local_port

# SSL proxy that serves the API (set if is being used)
:ssl_server:  mycloudentrypoint.cern.ch

Hope this helps.
