Re: [one-users] accessing VDC using Cloud APIs
Hi, Thanks for the response. I tried to use the REST service with data formatted in JSON using HttpBuilder. I would like to know the authentication method for using the service. When I tried to use the auth.basic method for setting up userid and password, it return 404 Unauthorized error. But I can see that the OzonesClient.rb is using the auth.basic to set the credentials. Any idea if I am doing anything wrong? My objective is to create VDC using the REST services. Thanks, Prakhar On Sun, Sep 18, 2011 at 3:36 AM, Ruben S.

Re: [one-users] Error monitoring host
Thanks for your help. As I said in my original email, I thought it was a funny problem, since everything used to work before and suddenly stopped working, w/o me doing anything. Well, as usual, funny problems are normally the result of stupid mistakes. I actually did something that prevented the monitoring to work as it should. I re-started Opennebula, but I did it as root. Now i have re-strated it once more, this time as oneadmin, and everything works as it used to. Thanks again for the help and sorry for bothering you with stupid problems.
