问题 I was trying to launch a instance VM to do some test. I selected the image orion-psb-image-R4, but when I launch the instance, an error appears: (Status:ERROR Power State:No State), is impossible to associate an a Public IP (Error: undefined.

For example, you can find in port 22, without it, you cannot access your instance via ssh. You need to

问题 I have a FiWare GE instance setup, with a security group, key, and IP all configured. I also have Putty setup to allow me to connect to the instance. My problem is that when I connect I get asked for login information. I've tried my login credentials for Fi-Ware but that doesn't work. There are no other users associated, so I'm not sure what I'm supposed to use. There doesn't seem to be any (obvious) way to create users and associate them with an application either. Are there default login

由 房东的猫 提交于 2019-11-26 23:06:35
I know that FI-WARE offers a public yum repository at http://repositories.testbed.fiware.org/ that can be used to install FI-WARE packages such as Orion contexto Broker.
